Upgrading your attic insulation and ventilation systems will improve your home’s efficiency. Proper ventilation in your attic is a crucial part of your home’s overall insulation system and air circulation plays a major role in keeping your home cool in the summer and preventing warmth from escaping in the winter. It will also prevent condensation build up in your attic, which could cause costly moisture damage.

When you have upgraded insulation blown into your attic by a professional insulation contractor like 4 Weather Insulation in Calgary, they will ensure your ventilation system is up to snuff. This allows them to blow that highly efficient insulation into all the nooks and crannies of your attic, giving your home the proper R-value throughout the entire space.

How the Attic Ventilation System Works

It’s all about air flow! In order for your home insulation system to be effective, you need a constant flow of air in your attic. Depending your home and attic, 4 Weather Insulation will ensure your vents are correctly sized and positioned to provide constant air movement throughout the entire attic area. This air movement will push out the hot air in the summer and move out any condensation that might form in your attic in the winter, reducing the strain on your heating and cooling system and lowering your energy bills.

Benefits of Proper Ventilation in Summer and Winter

Without proper ventilation, the temperature in your attic can increase substantially.  If you have moisture in your attic and it is overheated, you could face a number of problems including damage to your roof decking and shingles. Heat from the attic will also transfer into your home, causing uncomfortable temperatures and appliances like your air conditioners, fans and refrigerators to work overtime. This will increase your energy bill.

In the winter, condensation could start to build up in your attic and without proper ventilation it will not be able to escape. Condensation can damage your roof decking, causing it to swell or rot. Major condensation build-up can also cause the wood in your attic to rot, mold or mildew which can cause health hazards in your home. This condensation can drip onto your insulation, reduce its effectiveness and even start leaking into your ceiling.

Proper ventilation and upgraded insulation can also prevent the form of ice dams in the winter. Ice dams can form on the edge of your roof when the attic is warming the roof surface causing the snow to melt. When the water from the melted snow runs down your passed the exterior wall and hits the unheated edge of the roof it freezes. Over time, this thawing and freezing will start to accumulate ice build up which could damage your gutters, shingles or even cause a leak in your attic.
