Construction Progress: Week of Apr 22

Insulation spraying was completed this week, inside and out. Since in typical construction the majority of heat and energy loss is through the roof, the insulation in the roof was sprayed on both the exterior and interior. This detail allowed for much thinner roof members while nearly doubling the amount of insulation. For more information about the installation process of the insulation used see “Construction Techniques: Spray Foam Insulation.”
