Client: Tom Holmes
Project Type: Residential Construction
SIP Benefits / Energy Savings: Seamless construction and superior insulation significantly outperform spray foam
R-value: Thermocore's SIPs with polyurethane increase R-value with thinner panel
Builder: Glenville Timberwright
When a devastating flood washed out Tom Holmes’ Wisconsin timber framing business in 2008, he decided to showcase green building techniques as he rebuilt. He used spray foam in the walls of his shop and production area, and Thermocore structural insulated wall and roof panels in the office area.
In January 2010, Tom, president of Glenville Timberwrights, asked his HVAC contractor to test his building with a heat gun. The temperature outside hit zero degrees that day. In the shop area, the walls registered in the 50-degree range. But in the office area covered with Thermocore Structural Insulated Panels, the walls, windows, and floor all registered in the 70-degree range.

“It was very consistent from room to room, floor to ceiling,” Tom said. “Our HVAC contractor said he’d never experienced anything like that in 30 years of business. The way these insulated panels wrap up the building with seamless construction is far superior to any other product that uses studs to interrupt the insulation.”
