Key Learning outcomes
  • Why you should ventilate roof structures and buildings
  • Understand the principles of wind powered ventilation
  • Why this ventilation system is eco-friendly
  • Why condensation occurs under the roof
  • Benefits of wind powered ventilation
Every roof and building requires a good air exchange. Ventilation turbines can be used in private and commercial sectors of building construction for most types of roofs and ventilation shafts. This article explains how air exchange helps to protect the roof structure from humidity and overheating, importance of ventilating buildings and also how this system ensures active and permanent ventilation and thanks to the fact that it uses wind energy, which is free, it is environmentally friendly and cost saving.

1.0 Ventilation And Why Ventilate

We all know that ventilation is very important, but what exactly is ventilation?
Ventilation is simply the process of providing a continuous supply of outdoor air to the attic space of a home or general areas of any building.

What is proper ventilation?

In order to have proper ventilation, ventilation needs must be specifically calculated based on attic space square meterage and correctly installed.
Proper ventilation consists of 50% intake ventilation placed near the lower part of the attic space, and 50% exhaust ventilation placed near or at the roof ridge. The exhaust ventilation should be at least 1 metre higher than the intake ventilation.
It is estimated that a lot of homes have some form of improper ventilation. Fortunately for homeowners, contractors, and roofers there are wind powered turbines to supply the proper amount of ventilation to existing and new constructions.
Why Ventilate?
You may be curious as to why ventilation is important – ventilation is very important for many reasons.

In order to fight heat and moisture, homes in all climates must be ventilated year-round.

Heat in unventilated attics may cause really high temperatures in the roof structure. This can cause damage to shingles, roof sheathing, and also radiate down into the living area.

Moisture is a home's number 1 enemy, and can cause rot, mildew, mould, paint blister and ineffective insulation.

It is estimated that over 50% of homes show visible signs of improper ventilation.
