Types of Attic Insulation

If you have an Fiberglass insulation company Palm City, you have a barrier against extreme temperatures and energy loss. However, the majority of hot and cold air enters your home through the roof. This may result in moisture and water vapour problems. Aside from causing mould and wood rot, moisture can also cause damage to your roofing. Luckily, there are ways to prevent these problems from arising.

A common type of attic insulation is fiberglass batts. These batts are usually made of fiberglass and provide an R-value of 3.1 to 3.8 per inch. The thickness of the batts helps determine their insulating value. It is important to purchase a batt that is thick enough to reach the top of the joists.

Other options for attic insulation include fiberglass blankets and loose fill materials. These types of materials can be blown into the attic or poured into the cavity. They are a great option for small spaces that don’t have adequate headroom. This type of insulation is also great if there are numerous small holes.

Alternatively, you can install a polyethylene air barrier between joists. This type of insulation can also be installed in the rafter space. If you are using a polyethylene air barrier, make sure it is sealed against obvious air leakage paths.

Aside from blocking moisture, rigid board insulation can also increase thermal resistance. This type of attic insulation can be used to cover a gap between ceiling joists or to close an exposed cavity. The insulating value of this type of attic insulation can be improved by adding a second layer of batts. For example, you can run a second layer of batts across the top of the joists, perpendicular to the first. This second layer should be trimmed to fit tightly around ventilation outlets.

In addition, foam board can be used to seal a ceiling joist opening. For the smallest gaps, you can add cut pieces of extruded polystyrene to reduce heat loss. For larger gaps, a two-part spray foam kit can be expanded to seal around the joists.

Another option for attic insulation is a vapor barrier. This type of material can be installed between joists and sheathing. It can help to make the process of installing insulation easier. It can also be applied over the existing insulation to eliminate moisture and ice dams.

If you plan to add a dormer to your home, you can use dense-pack blown-in insulation to add an extra layer of insulation. This type of insulation can be installed in most rafter spaces, extending all the way to the eaves. It is also an easy way to add a layer of insulation to an already insulated attic.

If your attic is not finished, you can paint the ceiling below it with a latex vapour barrier paint. If you don’t want to seal the dormer, you can paint the ceiling with oil-based paint.

If you’re planning to enclose your attic, you should also consider a gable vent. Gable vents can prevent wind from blowing through the insulated attic.
