Attic Insulation

DIY Attic Energy Savings

Adding insulation to the attic, basement, walls or other areas of your home are do-it-yourself (DIY) projects, with substantial benefits. Properly insulating your home is one of the fastest ways to increase a home’s energy efficiency, and save on heating and cooling costs.

Gone are the days of fiberglass splinters, heavy insulation products that are hard to cut, and blown in pieces that take a lot of material for adequate coverage.

R-TechAtticInsulfoam’s R-Tech lightweight rigid insulation panel products are ideal for homeowners looking for a DIY insulation method.  Homeowners and builders can quickly and economically increase your home’s insulating power with these large lightweight panels that can be cut simply and easily to fit virtually any space.

Available from home improvement stores nation-wide, R-Tech comes in various thicknesses, panel sizes and fanfold options (picture unfolding 100 squares insulation in under 5 minutes!) without loose insulation all over, or pesky and painful fiberglass slivers to avoid.

Home Insulating Tips

How do I know if I need more insulation in my attic?

No matter what kind of insulation you currently have in your attic, one quick way to determine if you need more is to look across the span of your attic. If your insulation is just level with or below your floor joists (i.e., you can easily see your joists), you should add more. If you cannot see any of the floor joists because the insulation is well above them, you probably have enough and adding more may not be cost-effective. It is important that the insulation be evenly distributed with no low spots; sometimes there is enough insulation in the middle of the attic and very little along the eaves.  If your attic insulation covers your joists and is distributed evenly, you probably have enough.

R-Tech panels easily fold over the top of panel joists without the need to fill in gaps and low spots.

How Much Should I Add?

Insulation levels are specified by R-Value. R-Value is a measure of insulation’s ability to resist heat flow. The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38. A layer of R-Tech is a fantastic way to beef up attic insulation with fast and easy installation. Lay directly over trusses, planks, or subfloor and these large panels can fold out (fanfold) or be joined together with very few gaps for heat/cooling to escape through.

Note that EPA recommends air sealing the attic before adding attic insulation.
