The most important step in residential energy conservation is the installation of thermal insulation. That is why DOCO has developed two new seals that provide extra thermal resistance to your HOME door system.
Our new thermal seal (225017) has a U-value up to 12% higher than our standard seal. When adding the optional Q-Lon seal (225018), both the U-value and air permeability classification increase.
In the image below you can see the three levels of thermal resistance.
- Standard seal
- New thermal seal
