Using Structural Insulated Panels for Airtight Energy Savings

Peckham Architecture’s LEED Platinum, phius certified home office performs at net-positive energy, which means that it produces more electricity than it consumes. We could not have achieved this level of energy efficiency without super insulation. In addition to insulating our concrete slab foundation, we used structural insulated panels, or SIPs.

we source our green building materials locally as often as possible. The structural insulated panels for this project came from Thermocore of Missouri, located just 40 miles from Columbia in Taos, Missouri.

Thermocore’s SIPs contain injected polyurethane foam insulation with a Class A Fire Rating. In addition to providing superior and fireproof insulation, injected polyurethane is incredibly dense, strong and moisture-resistant. A closed cell gasket seals the gaps between the SIPs so no heat or air escapes.

Here are a few of our structural insulated panels on the jobsite:

This airtight method of insulation maximizes energy efficiency and makes the most of our green energy array, which includes solar panels, LED lights, ERV (energy recovery ventilation), a tankless water heater and Energy Star appliances.
