Home Blown-in Insulation & Gutter Solutions
23 January 2012
What features in a new house will affect its resale value? The curb appeal and the new kitchen surely will. But, as the cost of heating and cooling continues to rise, your home’s insulation and the quality of that installation could be a compelling factor.
Insulation slows the passage of heat through your walls and roof and so reducing the amount of energy needed for heating and cooling. In winter the insulation helps to keep the heat from seeping out; in summer it keeps the heat out.
Blown-in cellulose insulation has a high recycled content, and relatively little energy is used in its manufacture. Blown in insulation is the top choice of many builders for standard wood-frame home construction.
Fiberglass batt insulation is more widely used than cellulose to insulate walls, but it must be installed correctly. When it is not, the insulation is seriously compromised. The problem lies in the fact that fiberglass batts must be carefully cut to fit tightly around plumbing pipes, wiring, boxes for outlets and light switches, and any other irregularity in the outside wall. When there are gaps, heat passes easily through the wall. This is why it is best to have batt insulation installed by insulation professionals.
There is also a less common type of fiberglass called spray foam insulation because it completely fills the space between the wood studs, leaving no gaps. It contains about 25% recycled material and costs less than batt insulation.
Your home has more winter heat loss through your roof than through your walls, and you’ll need more insulation in your attic area under the roof than in the exterior walls below. The extra insulation will also cover summer heat gain, it is not uncommon to have summer temperatures in an attic exceed 140 to 150 degrees F. Because it’s faster to install blown-in type insulation into an attic cavity, most home builders use it.
