Project Update – Exterior Insulation at Blueberry Dr.

The CodeBoard system helps us achieve our performance goals in the following ways:

• The 1.5 inches of exterior insulation improves the effective insulation value of our walls by over 30% and eliminates the thermal bridging from our 2X6 wood framing and other structural wall components;
• The Code Board also acts as our air barrier and becomes an easier lower cost way for us to hit our air tightness target of 1.5 ACH (or lower). The continuous rigid insulation with the overlapping edges and proprietary tape along with some careful detailing around windows, doors and other holes makes it much easier for the guys to seal up the home and get us to our target;
• This is the most economical way we have found to improve our effective insulation numbers and economically hit our air change target;
• We also received great customer support from Owens Corning including an onsite orientation for our staff.
