Designers, architects and constructors discover the possibilites of buildings made with Structural Insulated Panels (SIP panels). This phenomenon comes from North America and it is for years a big success in the entire  industry! The construction method is widely applied in applied in Canada, USA and in Mexico as well. Also on the European continent you will find more and more construction companies who design and build with this concept: will Europe (and the rest of the world of course) follow the big success of America?

Constructions with SIP panels

SIP stands for Structural Insulating Panels. It is also known as a sandwich panel. A SIP panel consists of at least three parts. By combining an inner and outer board with a core of insulation, a SIP building system generates a wall with high strength and rigidity properties. This system is used for both bearing and non-supporting walls, but also for roofs. SIPs are high performance building systems for residential and light commercial construction. The result is a building system that is extremely strong, energy efficient and cost effective.

MgO and EPS insulation material

 

Core – Insulation

Many insulation options are available for a sandwich panel, we describe three of them: EPS, PIR and PUR.

✔ EPS is the abbreviation of Expanded Poly Styrene. It is a material that we encounter daily in our lives. Expanded polystyrene, commonly known just as styrene foam. It is mainly used in insulation materials, and because of its special properties, as well as packaging, ground, road and water engineering.

✔ PUR consists of a two-component sprayed foam that consists of: polyol and isocyanate. It has a high lambda value, and therefore defines heat loss in an excellent way. It is a widely applied insulation material. This is a CFC-free product and therefore environmentally friendly. The polyurethane foam adheres to almost any material. In addition, it is easy to use.

✔ PIR, or polyisocyanurate, is a plastic that is made specifically for insulation. PIR differs from PUR due to increased fire safety, especially in the field of flue gas development. In addition, the material absorbs no moisture. However, the main difference is the even higher insulation value of 0.023 – 0.026 W / Mk. For comparison: take glass or rock wool with a value of 0.040. PIR isolates approximately 1.7 times better for the same thickness. An exterior wall that is insulated with PIR remains relatively thin and has a excellent insulation.

Obviously, many other insulation materials are possible. An important aspect is that each insulation material has its own heat resistance, fire resistance and of course price.

Facings – Magnesium oxide boards

We were talking about the insulation, now we treat the outer two layers of the SIP panel. Most common is oriented strand board (OSB) used for the facings. But why not using MgO?
By gluing magnesium oxide (MgO) boards on either side of the insulation material, you will have an insulating panel. For convenience, we are talking about MgO sheeting material, which is also the chemical designation. One of the many unique features of MgO is that the material is non-combustible. To be more specific we are talking about European fire class A1. On the exterior the MgO board will be finished with a waterproof layer, like stone strips or cork. The interior can be painted right away or finished with plaster.

Cost effective construction 

Due to its prefab characteristics it is possible to build a rough building casco in a very short time frame. The application of SIP panels has great advantages over conventional construction methods. One of them is the lead time of a the construction of a house, which means that significant cost savings can be realized. A second advantage is the independency of weather influences, which means that you are able to guarantee continuous quality.

You save on material costs, but in addition you save money in construction costs further ahead. The production time and construction time on site is significantly reduced. This leads to a cost saving on labor. Moreover, a building in SIP panels is energy efficient.


Our MgO SIP panel: SINH™ panel

 

Circular construction and zero energy buildings

We have good news in case the client or customer indicated to want to build energy-neutral. Because MgO boards production process is more than fifty percent cleaner compared to (portland) cement if we look at the carbon footprint and CO2 emissions. Additionally, there are no toxic substances used in the boards, the life cycle is longer and the building material is 100% recyclable. We have investigated this in cooperation with TNO. (TNO is the Dutch Organisation for Applied Scientific Research)
To resume: MgO is a contribution to a better and greener environment!

What design options do we have?

Since this is a prefab building method all panels are constructed on a production facility. The assembly is at the construction site. These SIP panels can be customized according to all kind of design specifications. This provides the customer and architects enough opportunities for their own individual preferences.


New housing project in Nieuwleusen (The Netherlands)

 

An example in practice is our collaboration with the SIP panel producer RC Panels. In 2016, in Nieuwleusen (The Netherlands) they chose our MgO boards for a new construction project of zero energy houses. Please visit our project page with reference projects and all possible applications of MgO boards.

Benefits of SIPs

All benefits of SIPs:
✔ Reduction of construction costs
✔ Reduction of labour costs
✔ Reduction of lead time of projects
✔ Energy savings
✔ Wide range of applications
✔ Consistent quality
✔ Design flexibility

SINH website ¡Hola, bienvenido!

We have reached a new digital milestone, just two months after we have launched our SINH website in German. Now it is turn for our website in Spanish. From now on the Spanish speaking architect, the dealer and construction worker is able to get to know everything about versatile sheating material made of magnesium oxide (MgO). ¡Hola, bienvenido SINH!


Guggenheim in Bilbao, Spain

 

Spanish construction industry

After the bursting of the bubble in the Spanish construction and real estate market in 2007, after 2014 recovery in sight. The construction sector in Spain is growing again. The perpective for 2017 is a growth of 3 to 4%.

In addition to the economic outlook improvement in Spain, there is increasing emphasis on cost-effective construction solutions, innovation and sustainability in the construction industry. Several concepts such as prefabricated, circular building and building energy neutral attract more and more attention. Magnesium oxide boards is a perfect fit for these developments.

Latin America

MgO boards are widely applied in the construction projects in countries like Chili and Mexico. Especially if we mention prefab buildings and SIP panels. Which country follows on this continent!?

Buy cheap and waste money

Recently one of our customers drew my attention to the study “Magnesium oxide boards cause moisture damage inside facades in new Danish buildings” conducted by Kurt Kiel Overgaard Hansen, Tommy Bunch-Nielsen, Bent and Carsten Grelk Red. These authors are working at the Department of Civil Engineering, Technical University of Denmark and the Bunch Building Institute. The focus of the study was around treating the application of magnesium oxide, or shortly MgO boards in ventilated facades.

The article describes the effect of drops of saline (sodium chloride in water) (NaCl) leaked from the boards falling at screws, fittings and anchors of metal which resulted in negative impacts on the façade structure and a loss of several million Euros for the builder. The research concluded that MgO boards should not be used in ventilated façade systems and in situations where excessive humidity exists. The boards used by the Danes are dissolved by water and the drops of salt erodes metal construction materials. In the article several tests have been conducted to underpin the analyses.


ventilated facade in Denmark

 

Why you can not draw any generic conclusions based on this article?

The Danish investigators only refer to the sheathing board product that is used by this company. It is almost impossible to find out where this building material is purchased, as well as the composition of the boards and which quality control system is used in order to guarantee the performance.

The importance of CE-certified building materials

Our answer to this problem is a CE-certificate combined with a Declaration of Performance (DoP). The MgO board purchasing expert is aware of China’s availability of cheap and low range sheathing board products. You might come across Chinese producers who have a Quality Certificate and even a copy of a CE Certificate copied of somebody else. (Known as a Chinese Export certificate). The total expenses of European certification is more than USD 150.000. In addition, for many producers in China it is hard to comply with all requirements of CE marking. The plant of SINH (Ningbo) Construction Material Co. Ltd. is one of the few CE certified MgO board producing companies with audits of the Dutch independent organization KIWA. This voluntary CE marking ensures consistent quality that is recorded through an accredited DoP Declaration and an ETA (European Technical Assessment) by European standards. Therefore, it is of vital importance to purchase MgO boards from solid certified companies instead of going for a quick (and cheap) Alibaba deal.

CE marking

 

The chemical composition of the board

The article starts with the basic problem of the generation of tears on the board, which results in salty water, and consequently causes corrosion of the metal parts. Although a very thorough analysis, unfortunately the research does not conclude with a solution to the problem. The professional purchaser is already aware of the problem, with the recipe of non-certified MgO building materials and the knowledge that this will bring consequential losses in the future. It is impossible to mess with recipes having CE marking accompanied by a DoP, without any consequences for the CE certification. SINH Building Solutions is fully aware of the issues relating to the leaking of salty water on boards, with the amount of chloride and saw-dust in this product. With our unique recipe, we guarantee that the SINH™ board will not show the same problems that were described in this Danish study.

Why buy cheap and waste money?

A very common filling material for MgO boards is saw dust. This is a relatively cheap filler, which also fits perfectly in dry conditions. The producer can create more margin and/or guarantee low purchasing prices for the trader if he increases the amount of wood, which is at the expense of the amount of magnesium oxide powder in the recipe. These kinds of non- certified producers fail to show concern around the integrity of the board which may swell, mold or even start to rot. The same he can do adding big particle saw dust.

Application of MgO boards in facades

A MgO board is an open material, which means it has good moisture ab- and desorption properties. The application of this material in ventilated facades, could have been correct if the chemical recipe contained the right mix of material. Above that we always recommend our customers to protect the boards for all kinds of weather conditions. Doing so the MgO board will become an underlayment board. We have found many glue- stucco- and paint companies such as: Innotec, Schönox, Ardex, Codex, Coba, Bostik, Strikolith, etc. who have tested our boards thoroughly with submersion and freezing-thawing scenarios with some suppliers even providing a warranty of 10 years.

These companies also provide working instructions for the usage of their products. Options to finish the board are: stone strips, ceramics, cork, paint or plaster work.

Green building materials FIRST!

The Environment Committee of the European Parliament wants wants to ban the rights for the cement industry for free CO2 emission rights for building materials. This means we have to use greener building materials to contribute to a more sustainable world.

The cement industry has to buy her allowances at auction (Emission Trading System) starting from 2020 and 2030. The recent conclusion of “Carbon Market Watch”, an organization that follows the emissions market, is evident and shows the cement industry earned between 2008 and 2015 about 5 billion in excess free undistributed rights.

In February 2017 the European Parliament will vote on this proposal and the final decision follows in consultation with the European leaders.

CO2 emission building materials: background

Concrete is the most used building material allover the world. We need Cement in order to be able to make concrete. In addition we need a huge amount of ‘marl’ (calcium carbonate) to make cement. Calcium carbonate degrades during the furnace process in amongst 56% calcium oxide and 44% CO2!

CO2_Cement_SINH_Blog

In 2014 more than 4.1 billion m3 of cement is produced and processed worldwide, with a weight of more than 8.1 trillion kilograms leads to the same amount of CO2 emissions! Therefore the cement and concrete industry is responsible for 5% of the global CO2 emissions.

The biggest producers are located in China (54%) and India (7%).

The winners: green building materials 

In addition to all the initiatives already taken to make cement and concrete more environmental friendly and which are described in several articles, we offer a greener alternative, namely: magnesium oxide board materials. Magnesium oxide (MgO) boards are widely used in China, Japan, Australia, USA and Korea. In Europe, it is still a relatively new building material. SINH™ board is one of the few brands active in The Netherlands and in the rest of Europe. To produce magnesium oxide you only need the half of temperature of the production of cement and concrete. In conclusion our solution leads directly to a 50% cut of the total amount of CO2 emissions.

From now on it is: green building materials first!
It’s easy as that!

Guten Tag SINH™ Our website in German

Willkommen SINH™! We are proud to announce that from now on our website is available in German. Guten Tag SINH™!

With this milestone we reach Europe’s largest market. It is not sufficient having a website in English and doing successful business at the same time in German speaking countries, like Germany itself, Austria and Switzerland.

German construction industry

After years of negative prospectives, the German construction industry is growing since 2013! And the perspective is very positive. A lot of houses and other buildings have to be modernized and renovated the coming years. Sustainability and climate neutral construction are important matters in Germany. In this field Germany is leading in Europe. To produce and transport our SINH™ MgO boards to The Netherlands, we cause only 40% of the CO2 emission of concrete/cement/gypsum boards.

“This step is a logical consequence of the new strategy of SINH™ building solutions. Our main focus and future is Europe. We go for sustainable growth in Germany, Austria and Switzerland.”

About my experience of CE Certification

Withindia Building Solutions is a developer and supplier of innovative and sustainable magnesium oxide construction solutions. Furthermore we worked one and a half year on achieving CE-Certification for its core product: SINH™ board. Perhaps you might think: That takes long! Can’t CE Certification go any faster?

But I’m afraid you have to count on this kind of time laps if you want to introduce a new construction material on the European market. Particularly if you are busy with all other daily company activities.
Therefore I want to take you step by step into “my journey” of CE certification.

Step 1: the basis

First of all, everything starts with which product you want to introduce and which European standards you have to deal with. For us, this product is: SINH™ board
De base for CE-certification are the documents ETAG 18-1 (type 2, fire proof products for vertical walls) and ETAG  18-4 (type Z2, indoor use).

sinh-board_tapered_logo_branded

Step 2: European Assessment Document

The second step was to develop an European Assessment Document (EAD). We started this process in Augustus 2015 and its conclusion came in May 2016. We needed more than 70 tests in different labs to realize the EAD document. These results are registered in the EAD.

Step 3: Audits, Factory Production Control

The third step was Factory Production Control (FPC) by KIWA at our Chinese partner. For that the first audit took place in June. Subsequently not every detail was in order and a follow up audit became necessary.
This follow up audit was executed by Skype connection. A novelty for everyone. We walked through the entire production chain in China during the live connection. In practice we showed that a Skype audit works perfect, on the condition that all basic conditions are met. (like a visit at manufacturing site). All persons concerned worked in a constructive way together to meet the final result. In the end a GO for certification was given by the auditors. During the audit the open mind of KIWA regarding the use of modern communication methods has had a substantial impact on achieving this result in a reasonably short time.

Step 4: CE Certification

Our company received the CE-certificate including DoP (Declaration of Performance) on the 1st of October of 2016 of KIWA. Summarized: An excellent job!

ce-certification-europa

Finaly: my experience

The entire process took us one and a half year to achieve the CE Certifacation. It was a period of “blood, sweat and tears”. The whole path took very long and was very expensive.

But why can I recommend you this process?
Not only because you comply with regulations, but also going this path will increase the quality and consistency of your final product and satisfied customers. You are in fact forced to come down to the level of operational instructions, and to describe these in your new quality management system.

I can hear you saying: once you received CE Certification you can sit and lean back on your chair… Well, let me tell you: it will be the opposite! From now on you are committed to manage high product requirements and the process to achieve it.

Personally this is not my favourite project, but on the other hand it has been very useful and a blessing for the final result of our company!

Therefore I’m curious about what you think. Could you tell me more about your experience? Or do you have any questions? Please, let us know!

Main finishing options for Magnesium Oxide boards

Another question came in yesterday about the finishing of Magnesium Oxide Boards in case of exterior walling.

The most common exterior surface finishes are: Paint, Plaster and Tiles.

Before you start applying the finishing material:

When the MgO boards are fitted, the boards should not be exposed to the weather for a long period of time. Both heavy rains or high dryness will have their negative effects on shrinkage or expansion of the boards. These will cause cracks later when the finishing material is applied.
The MgO boards should also be clean and dry before starting finishing.
Small damages to the MgO boards should be removed or repaired.

Paint

Paint can be applied easily to the MgO boards. For exterior use, the boards should be primed with 1 or 2 coats of Plaster/Masonry Primer before coating with exterior quality paint. The primer works here as a sealant and water repellent that protects the ‘open’ structure of Magnesium Oxide Board.

Plaster

Cement plaster can be applied to the surface of the MgO boards. All joints between the Boards must be meshed with Fibre Mesh (preferably 4mm x 4mm) or wire scrim prior to applying the cement plaster coat.
After plastering, a sealant primer should protect the Plaster.

Tiles

Tiles may also be applied to the surface of the MgO boards. In this case it is recommended to roughen up the surface of the Board and put a suitable bonding agent (glue) on it before tiling. The amount of Glue has to be affluent.

When the tiles are applied for walls higher than 10 feet, these tiles should not be bigger than 1,3 Square Feet and thicker than 12mm.

Fungus and Magnesium Oxide boards: happy marriage?

Last week we were called by an Indian architect, who wanted to use SINH™ boards to cover air-condition piping’s. He wanted to know if Magnesium Oxide Boards would host or stimulate the growth of fungi in his construction.

As our company has not yet conducted a test to cover this issue, I started to search the internet for answers. First of all, you should know that there are thousands of species of fungi. Most of them are unharmful, only few of them cause illness and allergies.

Like Duane Craig (2009), who is a blogger for The Construction Informer, wrote in 2009: “Most of the time even though mold is present in our buildings it isn’t actively growing to the extent we can see it with the unaided eye. Then too, mold growth is greatly affected by humidity and since many of our buildings are air conditioned, or use dehumidifiers, the opportunity for mold growth is diminished.”

I also came across an article of Pamela Hargrove (2004): Testing for Fungal Growth in Building Products: a collaborative Effort. This article shows main tests available and developed in cooperation with ASTM, the American Society for Testing and Materials.

To summarize, there are 3 main test methods for the panel products industry available:

1. ASTM G21 – is a method used to test synthetic polymers including poly(vinyl chloride) and plastics.

2. ASTM D 3273 – is a standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber. This standard is for fungal growth in soil, contained in the humidified environmental chamber. Air circulation within the environmental chamber circulates the fungal spores in the chamber to the vertically suspended samples four inches over the soil. Weekly photographic images of each sample are emailed to customers so they can follow the progress of the testing.

3. ASTM D6329-98(2008)– Standard Guide for Developing Methodology for Evaluating the Ability of Indoor Materials to Support Microbial Growth Using Static Environmental Chambers. The test is designed to run for 12 weeks, four times longer than ASTM D3273. The quantitative assessment here is a count of the number of colony-forming units (CFUs) taken from samples collected during weeks 1, 6 and 12, and compared against the baseline level of CFUs at the start of the test.

Some other standards (not limitative) that have been published for testing of materials for resistance to fungi are:

  • MIL-STD 810E – Method 508.4 – Determines whether fungus will grow on a device exposed to warm, moistured air in the presence of fungus spores. The MIL-STD 810 involves spraying the test items with a composite of fungal spores and supporting the test items in the environmental chamber for 28 days.
  • ASTM C 1338 – Fungi Resistance of Insulation Materials and Facings
  • ISO 16869 – Assessment of the Effectiveness of Fungistatic Compounds in Plastics Formulations

To address the need for uncoated building products including gypsum board and cement board, a task group was formed in February 2004. The proposal in 2011 for a new test method ASTM WK32079, (Test Method for Determination of Mold Growth on Building Products designed for Exterior Applications) is one of its results.

In conclusion:

  1. Each test has its own strength and limitations;
  2. There are no special designed test methods dedicated to test fungi resistance of Magnesium Oxide Boards (external & internal applications);
  3. To limit fungi growth best is to manage humidity. To manage humidity, the architect and builder have to pay attention to building design, product choice, good construction practices and proper maintenance;
  4. Characteristics of Magnesium Oxide Boards as a material do not favour the growth of fungi due to its open molecular structure and high permeability to vapour.

 

My answer on the question “Fungus and Magnesium Oxide boards: happy marriage?” would therefore be “NO”.

Magnesium Oxide Boards: Innovative solution for Architects and Designers?

Last December 2015, our company had a stand at Credai Gujarat Builders Exposition in Ahmedabad.

A lot of visitors were very eager to know more about Magnesium Oxide Boards. So that is why I hope this article may provide some clarity.

Magnesium Oxide Boards are usually referred to as MgO boards. It is a factory made product. Most manufacturers can be found in China. Finding a trustworthy supplier can be a hassle and will consume a lot of your time.

The boards are made of Magnesium Oxide, a mineral bonded cement. This mineral supports a lot of important features like fire resistance, water resistance, its light weight, and resistance to mold and mildew. MgO boards are available in various thicknesses and sheet sizes. The board makes a hard sound when you rap with your fingers on it.

Magnesium itself is a silvery metal and is a solid at room temperature. It is lighter than Aluminium. As a metal it is mostly used in alloy form, particularly for lightweight high performance structures like airplanes. Pure Magnesium in its raw form is not stable –it burns. Magnesium Oxide however is the exact opposite: it is completely non-flammable and used for fireproofing.

Magnesiumcabonate is a stone-like material, which exists in large deposits as raw ‘rock’ and is mined like other minerals. It is ground up, crushed and calcined at temperatures between 450C and 900C. During a chemical process Magnesium Oxide is made. This is crushed into a powder with different purities. For usage in building applications purities between 80-85% are good enough.
Photo of Magnesium Carbonate (Magnesite)

Big raw deposits of Magnesium Carbonate can be found in China (80%), India, South Korea, Brazil, Turkey, Greece, USA, Canada and Australia. The deposits to be found around the world are so big that this resource will be with us for decades. In the MgO Board Factory Magnesium Oxide powder will be used together with some other additives as well. These include saw dust, Perlite and Magnesium Chloride. Also fibre mesh is added to build upon the strength of the board. MgO Boards can be used for various applications like walling, flooring, under roofing, ceiling, tile backing and underlayment, furniture and duct covering. In India very nice decorations are made with the boards as they are also very easy to (water) cut by CNC.

When you start designing and use MgO boards, you will find numerous applications to choose from. Like its size (twice as large as gypsum boards) or its weight (half of cement fibre boards) or its water resistance (unlike like Plywood and Gypsum boards).

The MgO Boards also contribute to lower building cost (material, labour, energy):

  • The boards are use in dry construction so you can skip lorries carrying cement & water;
  • The boards enable light weight designs of roofs & floors which will lower your bills to steel constructors;
  • The acoustic capabilities will provide alternative material for ceilings;
  • The boards replace concrete and steel constructions for your roofing thus saving cost;
  • When you need a fire resistant construction you can design thinner layers than you normally would do with traditional materials.

Concluding when you are interested in applying this relatively new material in India, you might consider the following points:

  1. For which purpose am I going to use the MgO Boards?
  2. Can I build upon the specific features of this material?
  3. Can the board help reduce building costs when I design smartly?

A company that has implemented groundbreaking projects in Amreli, Surat, Bardoli, Navsari and Ahmedabad. Avadh has a strong reputation for pioneering innovative building solutions in the design of lifestyle projects, and its quest for innovation led to the sourcing of SINH™ board for roofing underlayment for this project.

Avadh’s choice of SINH™ board was based mainly on the fact that SINH™ board is strong and lightweight, making it possible to reduce the load on the rooftop structure. This generated significant cost savings in the steel roof construction, as well as for transport and labour costs.

Other compelling arguments for using SINH™ board were that SINH™ board is fire- and water-resistant, highly durable and can serve as an excellent insulation layer for both hot and cold. All these properties enabled Avadh to comply with the most stringent of health and safety requirements in this project.
