What is a SIP?
S-I-P stands for Structural Insulated Panel. SIPs have been used for many years to build homes, commercial buildings, high-tech assembly rooms and cold-storage facilities. SIPs provide the frame, insulation, moisture barrier and exterior sheathing. For homes, the interior and exterior wall surfaces are finished with the same materials as in traditional construction. Not only does this simplicity of design provide a superior structure, it also greatly streamlines the construction process.
Understanding Why a SIPs Home is a Better Home
Lower Monthly Housing Costs
Improved energy efficiency - up to 70% savings on energy bills
ENERGY STAR® mortgage rates for those who qualify
Many insurance companies give discounts for metal panel construction
No preventative termite treatments necessary
No maintenance or repair bills for wood problems (warping, wood rot, mold, termite damage)
Indoor Quality
Quiet - SIPs walls and roofs demonstrate superior sound attenuation- even exhibiting higher Sound Transmission Class (STC) values than brick or block walls
Consistent Temperatures and Air Quality - the SIPs tight building envelope virtually eliminates air infiltration and leakage thereby eliminating drafts, and hot or cold air pockets within the home.
Fewer Pests - the tight building envelope makes intrusion of insects and other pests less likely.
Safety
Strength - SIPs homes have a greater resistance to wind damage than wood frame homes. There is significant evidence that SIPs homes are much more likely to survive natural disasters. One of the many reasons for this attribute is their ability to sustain winds of up to 140 mph.
Fire Testing - metal SIPs panels have demonstrated superior characteristics in fire testing when compared to traditional wood frame.
Design Value
Speed - SIPs houses go up faster, saving labor and time. Less labor and interest expense means that more of your investment goes into superior materials.
Flexibility - doors and windows are cut out of the walls after erected. As a result, design changes can be made relatively late in the construction process
