Kingspan recently introduced Kooltherm K9 Internal Insulation Board, a premium performance insulation product used for interior exposed application on basement, crawlspace, attic and habitable space walls.

In this article we’ll present the two methods that work together to achieve compliance with modern energy code air leakage requirements.

The market for residential zero-energy buildings grew 59 percent across the United States and Canada last year, according to a new report.

CertainTeed’s new SmartFlash ONE roof flashing resin is a one-component, UV-stable, fluid applied solution designed for both steep and low-slope roof flashing details and repairs.

The United States has long had tax incentives encouraging domestic energy production, for everything from oil and gas to nuclear and wind power. We do this for many reasons: to ensure stable supplies of home-grown power, to make energy more affordable, and to incentivize cleaner, greener options.

Crandell’s presentation provides an excellent primer on the many applications of continuous insulation based on a comprehensive body of building science knowledge resulting in recent building code and energy code advancements.

For a boat hull, it is best to essentially eliminate wetting potential with the use of a highly water- and vapor- resistive hull, or at least outer coating on the hull, right?

Unlike boats, a building’s walls must have some capability to “breathe” instead of being totally impervious to all forms of water.

I’m a second-generation home builder working in northeastern Connecticut, and I’ve been building net-zero energy homes for about 10 years. In my early years doing this, I experimented with structural insulated panels (SIPs) and other methods, but these days, I have settled down to a formula based on a cellulose-insulated double stud wall sheathed with plywood on the outside, and a flat attic with deep blown cellulose.

Halo Exterra, a foam board insulation for above-grade exterior insulation applications is also designed to be a water-resistive barrier (which means that no building paper needs to be used).
