Glazed windows and doors
Glazing of windows and doors is what allows the outside environment to interact with the interior of the house, a relationship that can be both good and bad. It’s good when we open doors and windows up to allow cool summer breezes inside, but it’s bad when all that glass sucks the warmth out of a room on a frosty winter evening, or lets the hot afternoon sun heat up the internal temperature to unbearable levels.
Glazing is usually the Achilles heel of a building’s performance. The Australian Window Association (AWA) estimates that up to 40 per cent of a home’s heating energy can be lost through windows and up to 87 per cent of its heat gained through them. Choosing high-performing windows and placing them appropriately can reduce your energy costs significantly and improve the thermal comfort of your home. The art is in knowing how different windows will interact with the design of your home.
But where do you start to work out which glazing system or treatment is the best solution for you? It’s a complex task even for a switched-on homeowner. We look at some of the main considerations below; for more detail, see our window and film buyers guide in Renew 143. We also recommend Your Home as an excellent resource.
