Probably the most common and popular window type is a casement window that opens outwards with a combination of top and side openers as well as fixed panes. These are particularly suited to modern homes and give a fresh and clean appearance.

If you want something a little different, go for a sliding sash window that’s more suited to a traditional style of house. A further alternative is a tilt and turn window that is particularly suitable for large openings. This type of window can be partially opened from the top to allow ventilation or can be fully opened by swinging inwards on side hinges for easy cleaning.

We can fit bay or bow windows, those suitable for cottage style properties, various styles and colours, including wood effect, with the possible addition of complementary shutters that will deliver exactly the look you want. That’s because every double glazed window installation is specifically designed and custom made for each location.

Benefits of Less Condensation from Double Glazed Window Installation in Melbourne

If you’ve never dealt with condensation-related issues before, count yourself lucky! We have customers who came to us purely because of it seeking Melbourne double glazed window installation. Excessive condensation can cause anything from persistent nuisances to incredibly expensive structural damage, and it’s something no homeowner looks forward to dealing with. Our Australian double-glazed windows save you from having to deal with that nightmare on a regular basis. For this reason, our Melbourne double glazing services have become extremely sought after.

When you have persistent condensation on your windows, all that water has to go somewhere. It doesn’t simply evaporate; a lot of it accumulates under and around your windows. Eventually, that water turns into a ripe breeding ground for mould and mildew, which most homeowners are probably familiar with. Mould can be little more than an ugly annoyance when it sits under the windows around your house, visible to you and any guests. Meanwhile, mildew can leave behind its signature unpleasant smell, which seems to never go away once you let it settle in.
