Description

INSULATED/SOFFIT RAFTER VENT t/
A unitary insulated vent chute and blocking body to provide greater and full width of air flow in an attic while blocking added insulation above ceiling from exiting to the eaves area and from being moved by air flow, therefore creating a greater R-value to the perimeter of the roof/ceiling areas.
The product is made from extruded foam board (either rigid, semi-rigid or flexible foam)that measures approximately 22" wide to fit between the rafters and approximately 3' to 4' long( tabbed or friction fit), tapered or slatted cuts across full width part way up (approximately 5" from end that rests on top plate of wall) to extend between 8" to 10"this allows ease for bending to form along rafter( slotted cuts may not be necessary if foam is flexible, see diagrams),.
The thickness of the foam board depends on the R-value of the foam, but recommend an R-20 to match the R-values of the wall system for continuous R-values,(minimum of 2"
thick to maintain vapor barrier specs) Also a reflective coating/material (metal type or polmer/plastic or material type) that is permanently attached to the underside of the body , this is to seal and strengthen the folds( bending area)and to reflect any heat loss that permeates through the attic insulation back into the insulation instead of being drawn out by air flow. The reflective material also acts as a tabbed strip on both longitudinal sides for attaching to rafters. ( the reflective is an added bonus to the body,and is highly recommended).
There should not be any reflective coating/material on the top side of the body facing the underside of the roof sheathing and shingle area, as the increased air flow will carry out heat away from the sheathing instead of reflecting it back into the sheathing causing premature damage to shingles.
BENIFITS
¨ Greatly reduces the potential of ice damming, roof rot and mould issues and early shingle deterioration.
¨ Allows full width air flow per vent for the whole roof.
¨ Insulated seal at top plate of wall system.(minimtun 2" thick to prevent frost and moisture penetration into attic/cellulose.
¨ Reduced chances of potential mould issues along ceiling edges along perimeter wall system.
¨ Increased warmth of interior perimeter walls by preventing "cold air drop".
¨ Lowers energy costs and greenhouse gases.
¨ Will allow builders/home owners to actually "meet"the building codes for R-values in the attic around perimeter wall ares where it presently cannot be met due to roof pitch and rafter/overhang design in majority of new homes and retrofits.
¨ Due to vaulted ceilings, this product can be used as a continuous to the roof/attic peak for greater efficiency to reduce energy costs of heating/cooling.
