SIPs vs. Stick
Build tight and ventilate right, that is the key difference in how SIPs outperform stick framed construction. When compared to buildings framed with dimensional lumber, Extreme's large SIPs cover greater surfaces with far less gaps in the walls and roofs to be filled and sealed. These large panels offer owners better indoor quality, reduced infiltration of outside pollutants, smaller HVAC systems, and a superior indoor temperature control. As a result, Extreme buildings stay cooler in the summer and warmer in the winter. Extreme SIPs have consistently outperformed other building methods of construction in both whole wall R-value comparison and energy efficiency. The best data we have are the happy customers that report the dramatic results of less energy used every month. Contact us for test data to back up the actual findings of our many satisfied customers.
Additionally, you can view in detail how SIPs compare to conventional 2x6 framing in terms of energy use and greenhouse gas emissions in an environmental profile study. That study tracks the environmental effects of both framing methods from raw material extraction through the 50-year lifetime of a single-family home (study produced by the EPS Molders Association - EPSMA).
