Understanding R-value and U-value
Jul 5, 2017 | Posted in Builders, Dealers, DIY, Framers

Knowing what R-value and U-values mean is key to following energy issues and to selecting products that best suit the climate zone you are building in. R-value is essentially a product’s resistance to heat flow. Adversely, U-value measures the rate of heat transfer. This means that products with a lower U-value will be more energy efficient. It is tempting to think that these two values are direct opposites of each other, but there are some important differences to note.

Raised Heel Trusses Improve Energy Efficiency While Reducing Costs
Oct 14, 2015 | Posted in Builders, Dealers, DIY, Framers

Stringent new building codes require improved efficiency of building envelopes through better insulation. While more expensive insulation methods, like spray foam, may have greater R-values, it is possible to meet the required high R-values using less expensive fibreglass or cellulose insulation with a raised heel truss.

Are Triple-Pane Windows a Good Investment?
Feb 3, 2015 | Posted in Builders, Dealers, DIY, Framers

As efficient building envelopes become more of a priority for builders, you may be considering investing in triple-pane windows for the R-value they offer. The technology behind window design has improved in leaps and bounds as manufacturers attempt to overcome the poor insulation value that windows traditionally offer the home builder. Unfortunately, the improved insulation comes at a high price. Do triple-pane windows offer sufficient energy-saving to justify the investment?

Phase Change Materials Make Windows More Efficient
Aug 11, 2013 | Posted in Builders, Dealers, DIY, Framers

Because glass is a poor insulator, the large amounts of energy that are wasted trying to keep the interior of office buildings and schools comfortable make glass unviable for those who wish to create an effective building envelope. Designers are torn between form and function, having to compromise either their vision or sustainability goals. Now phase change windows offer a new evolution in energy efficient window systems that will enable designers to let the light shine in.

Spray Foam vs. Radiant Barrier Sheathing: Pros and Cons
May 16, 2013 | Posted in Builders, Dealers, DIY, Framers

When installing attic insulation, a case can be made for both radiant barrier sheathing with typical types of insulation as well as spray foam insulation. A number of factors should be taken into consideration when choosing between these two, especially the climate zone that you’re building in. Radiant barrier sheathing is inexpensive and reflects thermal radiation to keep attic spaces cool. Spray foam offers insulation and provides some sound proofing from outside noise.
