Difference Between Attic And Wall Insulation

A blower machine allows the installer to place the materials precisely where they need to be.

Difference between attic and wall insulation.

Foam in place insulation can be blown into walls on attic surfaces or under floors to insulate and reduce air leakage. The right insulation for this wall would be 3 1 2 deep and 15 wide. Insulation types include loose fill batts rolls foam board spray board and vapor barriers. The insulation is with facing against the inside.

This installation technique keeps the insulation materials loose and crumbly allowing air pockets to naturally form between the fibers. On the attic floor i wan to lay some flooring and a small walkway. Unfaced means the insulation lacks a vapor retarder paper or plastic facing. These tiny air pockets slow down heat as it tries to pass through the insulation.

Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation. Residential insulation is designed for the four main areas of your home. This cotton candy like insulation earns its r value by trapping air in between tiny fibers. I want to cover the insulation with a thin layer of plywood or paneling on the walls of the stairway going up to the attic.

Find your zone on the map and then use the chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces. If the attic already has a layer of insulation up to the top of the joists use unfaced insulation with the new batts installed perpendicular to the joists. The most common insulation materials are fiberglass cellulose and foam. Kraft faced insulation includes a paper vapor retarder which helps prevent mold and mildew.

For example an attic should have insulation quality and volume that is rated between r 49 and r 60 in zone 7 regions like buffalo new york where it gets downright icy in the winter. Kraft faced insulation should be installed in exterior walls exterior basement walls and attic ceilings by pressing the product into the wall cavity with the paper side. Also it is an unfinished extra room. The type of insulation you need depends on which type is currently installed and the required r value.

Ceiling walls underfloor and between floor areas. Insulation is designed specifically for each area to ensure it fits the required stud spacing s cavity depth and thermal ratings r values. 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. In other words i see pink.
