A cure for thermal bridging

We have utilized a number of strategies to combat thermal bridging, the heat loss/transfer that occurs through the connection between conditioned and un-conditioned space by framing lumber. A relatively new product that we have recently utilized is the ZIP R-Sheathing from Huber Wood the maker of Advantech floor/wall/roof sheathing.

ZIP R-Sheathing combines the popular ZIP System sheathing and continuous foam insulation available in 1″ which includes 1/2″ R-3.3 foam, and 1-1/2″ which includes 1″ R-6.6 foam.

Some advantages of the ZIP R-Sheathing is 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.

Another new product that we have recently utilized for the fist time is “ZIP system Liquid Flash”. Liquid flash as the name implies 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 very tough and durable and looks to be an improvement to some previously widely used weather management techniques. Wear rubber gloves when applying liquid flash!
