Structural insulated panels (SIPs) are a high performance building system for residential and light commercial construction. The panels consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board (OSB).
SIPs are manufactured under factory controlled conditions and can be fabricated to fit any building design. The result is a building system that is extremely strong, energy efficient and cost effective. Building with SIPs will save you time, money and labor.
Panels are precut in our factory and delivered to the site ready for assembly. The accurate pre-cutting of SIPs panels saves time, by drastically reducing on site building time. By using SIPs, on-site construction time can typically be reduced by up to three times.
The SIP wall is both load-bearing and pre insulated, the structural shell is completed much quicker than traditional methods of construction. Erection times are known in advance, therefore SIP technology offers an accurate delivery dates.
The load bearing ability of a SIP relies on the strong BONDING between the OSB layers and the insulation core which it is formed by the self-adhesive PIR foam.
The SIP component interacts in a similar way to the web and flanges of an I beam where the OSB boards act as flanges by taking compression and tension forces, while the core spaces them apart, providing the construction thickness and shear stiffness.
In their current application, mainly residential and light industrial buildings the structural ability of the composite panel is well above the performance requirements.
The air tightness of the SIP building envelope prevents air from gaining access to the interior of the home except in controlled amounts.
A controlled indoor environment is both healthy and comfortable. Humidity can be controlled more easily in a SIP home, resulting in a home that is more comfortable for occupants and less prone to mold growth and dust mites.
Due to the air tightness of the building envelope that it is provided by the SIP construction system mechanical ventilation is required.
