We have utilized several strategies to combat thermal bridging. The heat loss transfer occurs through the connection between conditioned and unconditioned space by framing lumber.
We have recently utilized a relatively new product is the ZIP R-Sheathing from Huber Wood, the Advantech floor/wall/roof sheathing maker. ZIP R-Sheathing combines the popular ZIP System sheathing and continuous foam insulation available in 1″, including 1/2″ R-3.3 foam and 1-1/2″ 1″ R-6.6 foam.
The ZIP R-Sheathing advantages are a one-step installation of wall sheathing and foam envelope insulation, tight to weather walls as soon as the proprietary “ZIP” tape has been installed on the seams, and a reasonable balance of cost to build and energy efficiency. We will definitely use the ZIP R-Sheathing again on upcoming projects and recommend it as a consideration for your future new home construction project.
We have recently utilized another new product for the first time is “ZIP System Liquid Flash.” It is a liquid flashing material for sealing sheathing seams and preparing window and door openings. It is applied with a caulk gun and plastic spreader. The applied product is durable and looks to improve some previously widely used weather management techniques. Wear rubber gloves!
