SIPS vs Sticks: The Breakdown

Energy Efficiency Baseline Up to 58% more efficient
Fire Resistance Sticks require one layer of 5/8” drywall to meet an hourly wall. One hour firewall is achieved with 1 layer of 16mm Fyreline Jib for Type “L” panels or 2 layers of 16mm Fyreline Type “X” drywall for Type “S” panels.
R-Value The whole wall R-value data of a 4.5” SIPS wall rated at R-2.29 out performed a 140×45 wall with R-19 fiberglass insulation. Premier SIPS offer a 20 year R-Value warranty :
4” SIP = R2.29
6” SIP = R4.05
8” SIP = R5.28
10” SIP = R6.52
12” SIP = R7.92
Strength Baseline 20-30% stronger. The natural 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 provides the web. This gives SIPS an advantage at handling in plane compressive loads, that can be engineered for most applications. View load charts.
Seismic and/or Wind Yes, tie downs and additional material/ labor costs required. Yes, tie downs and additional material/ labor costs required.
Waste Created Baseline 30% less salvageable structural lumber sent to the landfills over stick, Premier SIPS are also recyclable.
Labor Costs Baseline Up to 55% labor savings.
IAQ – Indoor Air Quality Baseline The tightness of a SIPS envelope prevents air (carrying outside pollutants and allergens) from gaining access to the interior of the home except in controlled amounts, creating a healthy and comfortable indoor environment. Humidity can be controlled more easily in a SIP building resulting in more comfort and an environment less prone to mold growth and dust mites.
