Difference Between Wall And Attic Insulation

Foam in place insulation can be blown into walls on attic surfaces or under floors to insulate and reduce air leakage.

Difference between wall and attic insulation.

Residential insulation is designed for the four main areas of your home. The most effective places to add insulation to older homes are exterior walls attics basements and crawl spaces. Ceiling walls underfloor and between floor areas. As was the case for the ceiling cavity and eave space temperatures total r value does not tell the whole story.

The higher the r value the better the thermal performance of the insulation. Achieving greater r values in exterior walls in exterior walls add insulating sheathing to achieve a greater r value in your wall system. Most homes are insulated in the attic and any floors located above unfinished basements or crawl spaces. These tiny pieces of insulation do a great job at insulating because they spread evenly throughout the space wrapping around any obstacles like the outlets wires pipes and ductwork.

2d extend insulation into joist space to reduce air flows. You can achieve better thermal performance in your attic by adding an additional layer of insulation. In finished attic rooms with or without dormer insulate 2a between the studs of knee walls 2b between the studs and rafters of exterior walls and roof 2c and ceilings with cold spaces above. Attic temperature 0 f outdoors calculated difference.

The layer of continuous insulation in the 2 4 wall shields the highly conductive steel stud from exposure to near outdoor temperature. R values vary based on the type thickness and density of the material being used. Some installations can yield a higher r value than traditional batt insulation for the same thickness and can fill even the smallest cavities creating an effective air barrier.
