FAQ


1. How does the structural insulated panel design and fabrication process work?

A: The construction of a SIP home or commercial building begins with the construction documents. Once the construction documents are in the hands of a SIP manufacturer, they are converted to SIP shop drawings that give the dimensions of each individual panel. The shop drawings are reviewed by the builder, engineer, the building owner, and other involved parties. Once the shop drawings are finalized, the SIPs are fabricated and shipped to the jobsite for installation.

2. How strong are structural insulated panels? Why SIPs are so strong to bear heavy load?

A: The structural characteristics of SIPs are similar to that of a steel I-Beam. The OSB skins act as the flange of the I-beam, while the rigid foam core provides the web. This design gives SIPs an advantage at handling in plane compressive loads. SIPs can be engineered for most applications.

3. How do structural insulated panels react to fire?

A: Residential building code requires that foam insulation be separated from the interior of the building by a material that remains in place for at least 15 minutes of fire exposure. Structural insulated panels faced with a certain thickness of gypsum drywall meet different requirement in different building code.

4. Can structural insulated panels be modified on site?

A: On-site modification can easily be done using a few additional SIP specific tools. Panels can be cut using a beam saw or a beam cutting attachment to a circular saw. The foam core can then be recessed for splines or dimensional lumber using a hot wire foam scoop or specialized angle grinder attachment to recess the core.

5. How to install water pipes is your SIPs prefab house?

A: Plumbing should not be located in exterior SIP walls because of the possibility of condensation or supply lines freezing in cold climates. During the design phase of the project, all plumbing should be relocated to interior walls. Generally a small section of the wall using conventional wood framing that can be used to run plumbing.

6. What's the leading/delivery time?

A: The leading time can be 20 to 40 days from the date when your deposit was received according to the production schedule and what you ordered

7. How many houses can be loaded into one container?

A: it depends. Generally one 40'HQ can load around 100 sq.m in construction size.

8. Does the house come with interior and exterior finished? Can I have a complete house with everything ready?

A: Besides the structure/shell, we will try to provide as many as we can to save your cost and time. But other accessories and decoration materials are not made by us; there is no standard option and price. We can check the market according to your detailed requirements after the general agreement made on the structure/shell.

What we deliver to you exactly are precut panels and other elements, so any accessories or decoration materials should be installed after the complete shell was erected onsite.

9. What kind of foundation is required for SIPs house? do I need foundation?

A: Foundation is needed for SIPs house, and all kinds of foundation system can be applied. However, traditional concrete foundation is highly recommended. There only difference is some anchor bolts are needed as connection of wall and foundation.

10. Who will assemble the house? do you send workers to install the house for me?

A: We do not provide onsite service. Because the installation is quite easy, most of our customers can set up the house easily by support of our installation documents. It will be more economic and easier to do it by your local labors.

11. Do you have CE for your product?

A: For CE, I have asked Intertek which is a professional lab: their staff confirmed as our product is not the final consuming products and the consumer cannot touch it. Our products have nothing to do with the safety issue. So CE is not required.

We have exported any houses to the UK, Germany, Italy, France, Sweden, Denmark, Ukraine, Romania, Cyprus and so on, we never had problem with CE.

12. What's the life time of your house?

A: The design life of our SIPs house is 70 years. For any light structure building system, the better maintenance you do, you longer life span you can expect.

13. Is your SIPs house termite proof?

A: There is a kind of SIPs made of fiber cement board facings, it's a good solution to termite problem. And we use steel as connector to houses made by such SIPs. Then no wood inside, termite cannot eat steel or fiber cement.

14. How many storey can be built by SIPs?

A: SIPs is suitable for low-rise houses, though the highest SIPs building in the world is 6-storey, we suggest to construct a SIPs house under three storey. Then it's easier to pass the building code and save more material cost.

15. Does your prefab house can fulfill our building code?

A: Basically we follow the Canadian building standard, however, we can make house by custom requirements.

For building code, it's different from country to country, the customers need to check with their local council and get the permission, and we will provide full support.

16. Can structural insulated panels be modified on site?

A: On-site modification can easily be done using a few additional SIP specific tools. Panels can be cut using a beam saw or a beam cutting attachment to a circular saw. The foam core can then be recessed for splines or dimensional lumber using a hot wire foam scoop or specialized angle grinder attachment to recess the core。

17. What is the best heating system for a SIPS house?

A: Any conventional heating system can be used but should be downsized because SIPS houses are so energy efficient and airtight. Controls are important as heating demand can be low or negligible and overheating can occur. Ventilation should be designed into the SIPS house because it will not have the gaps and drafts present in many conventionally built houses.

18. What are the options for external finishes?

A: Almost total choice from bricks, natural stone, brick slips, polymer and cement renders, timber cladding and metal cladding.
