Optimal cooling and ventilation through 92 open air space.
Foam board roof vent.
Heat from the house rises up to the attic but when there isn t one the heat rises up to the roof.
The rigid foam is cut to be 2 inches wider than the space between rafters then 1 inch of foam is scored and folded over on either side of the foam creating standoffs that hold the foam away from the roof sheathing providing a space for air to flow.
Install it anywhere from the roof to the foundation.
Even small amounts of condensation can substantially reduce the r value of the insulation creating faster heat loss into the attic space and eventually leading to mold mildew rot ice damming and loss of.
Attach this roof and attic insulation treatment using foam baffles to ventilate insulate and channel cold and hot air to roof vents before insulation is add.
Superior air flow adhesive and ease of installation make plyco quick vent the leader in foam vent technology.
The plyco quick vent advantage.
They keep your home at a comfortable temperature without the need to crank your heat.
Rigid foam insulation also known as insulating boards provide high r values.
Cathedral roofs especially need a lot more insulation between the ceiling and the rafters because there usually isn t any attic space.
The edges of the wood panels are rabbeted to provide for expansion and contraction of the wood while allowing the foam edges to be installed tightly to achieve thermal integrity across the entire roof deck.
In an un vented roof foam can serve as the air barrier and vapor retarder and prevent moisture from getting in to the roof cavities.
Allows flat straight non bulging ridge cap installation.
Types of insulating boards.
Keeps pests and insects from penetrating.
Seals around major ribs.
You can even place it under the foundation slab.
Spray foam is a very expensive option however.
In a vented roof foam can seal the openings and serve as an air barrier and a vapor retarder in addition to its insulating function.
Foam insulation can play an important role in both vented and un vented roof assemblies.
Rigid foam and spray foam are two of them.
All insulation materials require proper venting.
Eliminates snow and rain penetration.
Foam board insulation would be a more economical especially if you are supplying the labor see photo.
