A Courageous Builder Embraces Advanced Framing Techniques

Advanced Framing Technique, also known as Optimum Value Engineering (OVE), is a change from 2 x 4 to 2 x 6 home construction wood framing. This concept has been around for quite awhile but has not been widely embraced by home builders.

Advanced Framing Technique enables a builder to use 20 percent less wood in the framing, which decreases the amount of labor and provides a stronger frame. While it’s a better use of raw materials and can translate into 20 percent savings, it does present a significant learning curve to the builder.

In building science, we love OVE because it creates a 5-1/2” cavity rather than a 3-1/2” cavity which allows for a better insulated home. As an insulation manufacturer (among many other construction products and systems) we would like to see more builders embrace this because it makes a more energy efficient building.

Don't Skimp on Insulation

On February 5, Martin Holladay from Green Building Advisor.com posted a Blog entitled “It’s OK to Skimp On Insulation, Icynene Says.” This was in response to open-cell spray foam manufacturer, Icyene’s position advising builders to install less insulation than the code requires and for building officials to approve insulation that doesn’t meet minimum R-value requirements.

Martin makes some very good points regarding the flaws in this thinking. Icynene’s position is that air-tightening a home will have a significant impact on the energy consumption of the home–which is absolutely true, but they are also saying that by doing this you can accept lower R-values. There is no reason to accept lower R-values. Builders should be able to do both: air-tighten a home and have the R-values that the code requires.
