Modern replacement windows are built to ever increasing standards of performance - providing the home owner/purchaser with products with ever increasing levels of thermal insulation and almost eliminating draughts. However, every house into which these products may be fitted is different and ventilation of the building is an important feature of performance which must be considered when specifying the products you want to install.

Its important that your house can breath

If your windows are already fitted with trickle ventilators building Regulations require that the replacement windows should have them too. If they are not fitted it is good pratice to review the ventilation requirements of your home when you are considering replacement windows.

Trickle ventilators fitted to the head of the window, or in th sash are the most common methods in replacement window, other options are a trickle vent “glazed” in with the glass, as shown above, or the simple “vent-a-matic” spinning air vents fitted to a hole in the sealed unit.

The advantages of properly ventilating your home include :

Fresh air can enter your property and stale air can escape, keeping the indoor atmosphere healthier
Potentially harmful airborne pollutants such as emissions from cleaning products, flooring and furnishings can escape from your home.
Odours and water vapour from cooking and bathing can be reduced
There is likely to be a reduction in condensation and mould, which could reduce damage to your decor and reduce potential health problems for asthma and allergy sufferers.
Some ventilation systems can be left open to allow ventilation at night or while you are away from home.
