I couldn’t be more impressed with your ventilation products. The entire process from ordering to installation was headache free. We’ll definitely be ordering again!

Each 8’ Vent strip provides approximately 1 sq. ft of airflow. Standard ventilation requirements:
1) 1 sq.ft. venting per 300 sq.ft. of attic floor space.
2) 60% of needed venting should be from the soffit area.
Proper roof venting is critical to good construction practices and maintenance. The purpose of roof venting is two-fold:
a) to reduce temperature build-up inside the roof cavity during the summer months
b) to reduce condensation-related problems, i.e. fungal wood rot during the cooler months of the year.
A good venting system, using Whitehaven wood SOFFIT vents, allows for a continuous flow of air. The air flow enters the cavity at a low spot in the roof (e.g., under the eave) and exits the roof at a high spot (e.g., near the ridge of the roof). As a general rule, there is no need to provide for any sort of mechanical assistance to the venting system.
A good venting system works adequately by means of a natural convection current where warm air rises and pulls the cooler, drier air behind it.
A good roof venting system must also be designed in such a way as to provide for proper air flow at all portions of the roof.
Improperly vented roofs often result in premature deterioration of the roofing material and fungal wood rot in the roof framing and sheathing.
It is not uncommon to find an improperly vented fifteen-year-old roof with badly curled (and thus non-functional) roofing material and advanced fungal wood rot on the lower side of the roof sheathing.
With the introduction of more insulation and weather sealing, as well as other building techniques which reduce venting, proper roof venting techniques are even more critical than in the past.

Bad roof ventilation can lead to deterioration, rot, and fungus in your roofing. Good vent and roof design increases natural air flow through your roof, minimizing damp and warping, and:

I wanted to share some pictures of your vents; when they’re installed, they look great!

Whitehaven Wood Products also produces vent strips for commercial applications too. We’ve recently completed and shipped these massive 7-foot long wooden vents for cooling station sheds in Alberta. This was a big project, but just as clean and professional as our domestic products.
