If you are deciding between insulating the roof deck or the roof, insulating your roof should be the priority. Chances are your house is roof insulated because this is easier to do, according to this insulation contractor. It can be insulated to some extent on the roof, but it is much more likely that your house will be insulated on the roof and not on the roof, than vice versa. Ice buildups and frost under roof cover can cause moisture damage to roofs, especially in 1 ½ story homes on Cape Cod.

You can find relatively cheap fiberglass wadding insulation in bulk quantities, as is the case with this roll of R-38 fiberglass wadding insulation from Owens Corning, designed to fit up to 341.36 square feet of attic space. Please note that this is the roll and not the loose filling. According to the U.S. In the US, Studies Show Radiant Barriers Lower Filling Costs by 5-10% When Used in Hot, Sunny Climates.

Localities usually have their own energy efficiency codes. For example, Florida's Energy Efficiency Code requires insulation to be rated at least R-19 to withstand hot, humid weather. Both roof and roof insulation are great options for insulating your home, but which one is best for you?. The biggest difference between these two types of insulation is where they are installed.

Attic insulation is installed on the roof plane, while roof insulation is installed on the roof slope itself, above and below the rafters. In most homes, the ultimate goal of insulation, beyond energy efficiency, is to maintain year-round comfort for the rooms below. As a result, we insulated the attic floor to optimize comfort in the main living areas. If we insulate the lower part of a pitched roof, we would run the risk of gaining and losing heat between adjacent rooms below and the attic, which would compromise the energy efficiency and comfort of the house.

In this context, the decision concerning the attic floor vs. Sure, you can lower the thermostat and get used to wearing bulky sweaters indoors to cut costs. But if you have an unfinished attic, giving it adequate insulation is one of the easiest ways to keep a lid on your heating bill this season.

Department of Energy estimates that an attic with adequate insulation can reduce 10 to 50 percent of your heating bill. And it works the opposite way for hot climates; in summer, it helps stabilize your home's indoor temperatures to keep cooling needs under control. Roof insulation usually refers to insulation that is installed between the roof rafters. Roof insulation means insulation that is installed under roofing materials.

Many builders mainly insulate the attic because it is cheaper and easier to install, and roof insulation is often poorly insulated. Reflective insulation will also help in winter, as it reflects radiant heat from sources inside your home to prevent heat loss. If your attic has enough insulation and adequate air sealing, and your house is still drafty and cold in winter or too hot in summer, you will likely need to add insulation to the exterior walls. The insulating fibers are packed in bags and blown into place to the desired depth and density with special machinery that you can rent from a home center.

When installing ceiling insulation, you want to maximize coverage, BUT keep ceiling lights in mind. This value is important information to help you select the right insulation for your needs. These techniques improve the R-value of the entire wall by reducing the thermal bridge and maximizing the area of the insulated wall. In unfinished attic spaces, insulate between and over floor joists to seal living spaces below.

Energy audit procedures may include the use of infrared cameras to detect gaps in insulation, as well as air and moisture leaks. Also insulate (4A) any part of the floor of a room that is cantilevered beyond the outer wall below; (4B) slab floors built directly into the ground; (4C) as an alternative to floor insulation, foundation walls of unventilated access spaces. Installing insulation is also one of the best things you can do to make your home more environmentally friendly. If you have a set budget to improve your home insulation, opt for attic insulation first, as it is cheaper to install and more cost-effective for you in the long run.

For example, cathedral ceilings built with 2x12 beams have room for standard 10-inch panels (R-30) and ventilation. . .
