If it s a nasty old attic vacuum it out and add a high merv filter on the return from the attic.

Closed envelope attic. Bringing the attic inside the envelope doesn t mean you can stop addressing the water vapor. Poor workmanship during attic and roof installation will result in expensive callbacks and repairs as insulation will have to be replaced. But when there s a hole in the envelope pollution can get inside not to mention lots of hot or cold air wind and precipitation. Intake vents located at the lowest part of the roof under the eaves allow cool.

When determining how to insulate this attic space various assemblies were taken into consideration and a hybrid combination of vented and unvented attic space was planned. To truly be a fully conditioned attic it should be included in the hvac or ventilation system. Pretty soon you re coughing and sneezing and trying to rub the dirt out of your eyes. My original plan was to build a conditioned attic and place 1 5 of foam xps board r7 5 installation on top of the roof deck and fill the old true 2x4 rafters and rafter walls with closed cell insulation and if able attach 3 of foam xps board r15 to the rafters in the attic.

A fundamental requirement of an unvented attic assembly is the use of air impermeable insulation on the underside of the unvented roof to prevent air infiltration and exclude airborne moisture from the attic. The dormers and the attic space over the outside porch were sealed off from the rest of the attic by making a wall of plywood then insulating the wall with closed cell spf. You re used to thinking of your car as a closed envelope which is why you weren t worried about the dust. The attic space becomes indirectly conditioned as a result of the air leakage heat transfer and vapor diffusion through the ceiling.

Spray foam insulation is more expensive than batt insulation and needs to be expertly installed to prevent missed areas or pockets that can reduce the efficacy of the building envelope.
