Frequently Asked Questions about Structural Insulated Panels

Many construction projects nowadays use materials that can improve structural integrity while attaining sustainability and energy-efficiency. One example of a building material that is gaining renewed popularity is structural insulated panels (SIPs). Structural insulated panels are pre-fabricated panels consisting of a built-in insulation core between two boards. Since not many people are familiar with this type of building material, it is essential to address some of the frequently asked questions about this product.

Can building using SIPs help save money?

SIPs are not cheap. But if you build using SIPs, you will cut the construction time by almost half. This will translate to savings concerning labour. Another way you can save money is by decreased energy consumption because SIPs will create an airtight building envelope. You will likely require smaller HVAC equipment by considering the superior insulation properties of a SIP structure.

Are SIPs environmentally friendly?

One advantage of using SIPs is sustainability. Manufacturers of SIPs sometimes use recycled materials to fabricate panels. Construction projects using SIPs also produce less waste. Moreover, a structure made with SIPs will use less energy in its lifetime than one that is built using traditional materials.

Are SIP panels resistant to fire?

Since SIPs are primarily constructed using wood, you will need to follow the required construction guidelines to fireproof a structure. Building codes for residential structures usually require the application of a fireproof thermal barrier.

Are SIPs compatible when used in combination with other building materials?

SIPs are suitable when combined with almost any kind of building material. Depending on the project plan, builders can use SIPs for roofing and traditional timber frames for walls. Conversely, you can build a structure using SIPs for walls and use traditional roof trusses. SIPs are also compatible with a variety of materials used in foundations, like poured concrete.

Can you easily modify SIPs on site?

Builders recommend avoiding adjustments and modifications to SIPs on site especially if it affects the intended entry and exit point for electrical wiring. However, it is possible and easy to make changes using special tools should the need arise.

Are SIPs susceptible to insect infestation?

Termite infestation is a common concern in many parts of the country. Although the insulation core will not necessarily attract termites, there are some cases when insects might feed on the board and nest in the foam core. As a necessary precaution, you can treat the panels with borate. Another method of deterring termites is to use a steel mesh designed for this purpose.

Is it possible to repair or replace damaged SIPs?

When there is damage to the panels, you need to contact an engineer first to assess whether the damage is merely cosmetic or structural. Cosmetic damage, such as that which is caused by moisture can be fixed from the outside of the panel. Structural damage, on the other hand, may require replacement or modification of the panels.
