We have upvc frames, double glazed windows with low e coating. We’re in western Vic, gets pretty chilly in winter. The low e coating we didn’t pay extra for, if we had to I wouldn’t have worried about it. We love the upvc frames. Don’t get cold like aluminium ones and extremely sturdy. We are building our ‘forever’ home which is why we went for the extra expense of the upvc. Longevity, thermal transfer and we liked the look of them a lot more than aluminium. There’s also none of the upkeep required by timber frames. We’re still building but we have seen how they perform through winter and summer (it’s taking us a while!). Through winter the house stayed very mild, we will rarely need to light the fire. Over summer house did get warm on extreme days but we are using scyon linear boards, not brick so I feel that has some bearing on it.

Maximise expansive coastal and hilltop views from every aspect, with carefully selected windows and doors to beam light throughout every corner. Bi-fold doors bring the outdoors in. Giving you the chance to soak up the surroundings. They stack seamlessly so any view is uninterrupted. For those windswept days, the bi-folds easily and securely shut, taming the elements whilst allowing the light to pour in. Large fixed windows make a bold statement. They create picture perfect views for overlooking the pool and coastline, flooding light into the home. This stunning holiday home in Victoria, know as Contemporary Coastal, was custom built by Langford Jones Homes.
