Spray Foam for Northwest Louisiana Attic Spaces 

Attic Insulation in Your Northwest LA  Home

LFE Spray Foam Insulation primarily uses the envelope method as the best technique to insulate an attic. In this method, spray foam is applied directly to the underside of the roof deck, forming a seal that envelopes the entire space from floor to roof. This creates a “conditioned” space, enabling the temperature in the attic to remain more consistent with the rest of the house.

Spray foam insulation reduces energy consumption in several ways when it is applied on a roof. It can essentially eliminate energy loss from ducts located in the attic. With less infiltration and exfiltration, excess moisture isn’t pulled into the attic since the top of the building is much tighter. Spray foam also reduces infiltration through the ceiling. It reduces energy consumption by eliminating extreme temperatures in the attic.

Including the attic in the insulated space can offer benefits such as:

• The issue of heat gain/loss from ducts, as well as duct leakage is substantially reduced.
• Sealing the roof from air infiltration is more feasible than sealing the ceiling from air infiltration.
• The living space will be clearer of loose insulation and dust.
• When the attic is sealed, test show that energy costs are reduced.
