When it comes to choosing insulation for your home, one of the important things to consider is R-value. R-value is the measurement by which you can tell how well a particular insulation can keep heat from leaving or entering your home. The higher the R-value the higher the resistance to heat flow, meaning better climate control and better energy efficiency.

R-Value & Energy Efficiency

Insulating your home or building is one of the most cost-effective ways to improve a home or building’s energy efficiency. That’s because heating and cooling account for as much as 60% of a building’s energy demand. So making sure that you have an efficient building “envelope” means that you can better control the interior temperature, and it goes a long way in reducing energy consumption (and lowering your carbon footprint).

ROCKWOOL Comfortbatt®

If you’ve watched any of my shows over the last 15 years you know that when it comes to energy efficiency I look to ROCKWOOL Comfortbatt®. Comfortbatt® is stone wool insulation that is used in exterior walls, attics, crawlspaces and basements, and it provides consistent, comfortable indoor temperatures and energy savings throughout the year.

There are several reasons why I use it. One is that it’s incredibly easy to work with. The batts are easily cut with a serrated knife to achieve an optimal fit around pipes, electrical wiring boxes, ductwork and between studs and joists that are less than the standard width.  They are made to friction fit between wall studs, so they fill the cavity completely and don’t sag or compress.  They also have the added benefits of providing fire protection and sound absorption. 

ROCKWOOL Comfortbatt®, comes in a range of R-values and widths to deliver top thermal performance.  Depending on where you live and the part of your home you’re insulating (walls, crawlspace, attic, etc.), you’ll need a different R-Value. If you’re not sure what you need, check out ROCKWOOL’s R Value calculator to determine the right product and R-value.

If you want to increase your home’s energy efficiency, few things will help as much as insulation with the right R-value. For more information please visit www.rockwool.com.
