Re: west facing windows in Perth and the heat 6Jul 20, 2019 3:01 pm Great post by arcadelt, agree with everything they've said. OP, good to see you've been looking through the Your Home website. It's extremely useful. I'd recommend that you continue looking for the right block. I'd say NW facing glass is as bad as W facing glass. As it's also very difficult to shade, & the sun is in this direction at the hottest time of the day. As you've probably learnt, double glazing does nothing to inhibit sunlight heating a home. Double glazing is effective against conduction (that is the transfer of heat/coolth from the air, through you windows & into your home). But it does virtually nothing for radiation (direct sunlight). Films or low-e glass can be somewhat effective, but nowhere near as effective as an insulated wall. Film on a large expanse of west facing glass would be like a band aid on a large open wound. As I mentioned, keep looking for the appropriate block. Large windows facing west would be the least preferred orientation. Then South I'd think, as they leak too much heat in winter. East is similar to west, & is difficult to shade, but occurs at a cooler time of the day. For large East facing expanses of glass I'd recommend an east facing covered alfresco area & external shutters to help shade the glass (this can also help western glass somewhat). North facing glass is by far the best, with appropriate length eaves. It might be a bit darker in the mornings but the light is still light, so you should be getting it.
