1. What's the leading/delivery time？
A: The leading time can be 45 to 70 days from the date when your deposit was received according to the production schedule and what you ordered and what time of the year you order.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
