Correct Attic Baffle Re

P i am currently building a cathedral ceiling room addition on a very limited budget.

Correct attic baffle re.

They allow the air to circulate under or near the insulation. For the plastic insulation baffles at home depot. Fit each one snuggly in the bay with the bottom starting where the ceiling joist meets the roof rafter. Installing baffles from a soffit vent and up the rafter bay allows you to insulate every available inch of attic floor space.

You will need a baffle for each space between the rafters. The r19 kraft faced fiberglass for the ceilings and walls 1000 sf cost me only 200. The soffit vents allow convective air movement from the soffits of the residence to the ridge vent. Use a zippered insulated tent to keep the enclosure draft free attic tent at 7 attic cover insulator 120.

Attic hatch or door. I have been fortunate to obtain many building materials at low cost. It is going to drive me crazy to spend another 200. Pull any existing insulation away from the edges of the attic where you will be putting up the baffles.

I can purchase a roll of housewrap 9 x 100. Without baffles you must keep vents clear of insulation which means. In addition insulation baffles must be installed at the point where the attic floor meets the roofline to prevent the attic insulation from migrating into the cavities and restricting the airflow from the soffit vents. Add weatherstripping around the perimeter and a sweep to the door of a walk up attic.
