Everyday activities like cooking, showering and washing dishes add moisture to the air, in cold weather, moisture that gets trapped in the attic can condense and lead to mould, even rotting wood (i.e trusses) and in warm weather excess heat build-up, not only makes the house less comfortable and energy efficient, it can also cause roofing materials to crack and age prematurely, not something homeowners want to think about. We at Global Innovative Building Systems are glad to provide you with the solution to this problem.
The VentSure® Ventilation System:
This is a patented ventilated system which has a unique design and easily installed between the ridge cap and roof deck. It generates air movement in the attic space balancing both indoor and outdoor temperatures and prevents overbearing heat loads trapped in roof voids. Condensation under the decking is eliminated in winter, thus preventing premature ageing of the deck.
How It Works:
It is a unique natural ventilation system, wind blowing over the ridge creates a negative pressure that draws the warmer air out of the attic space. Replacement air enters through the under eave vents, bathes the underside of the roof and exits at the ridge cap, through ridge vents, roof vents or gable vents. Even with no wind, the natural convection action of rising warm air maintains a continuous airflow along the underside of a roof.
A cooler environment is naturally created within the building. In cooler climates, adding attic insulation will also create ideal living space and comfortable working conditions. In warmer climates, ceiling insulation will also help to keep ‘cool’ air from entering the attic, further reducing energy usage on air conditioners. So now, your home has a better looking, healthier, longer-lasting roof.
