"Visiting the showroom and talking with Rudi and Sylvia gave us the confidence to go ahead with replacing 28 year old double glazed windows & sliding doors in our living room in harsh beach side conditions. Mario and staff installed the windows & doors efficiently, cleaning up after the job. Thank you for a reliable quality service. "

"Just replaced all our old windows with Astellite and I couldn’t be happier! The windows look amazing (double glazed uPVC windows, two coloured frames - black from the outside, white from the inside), plus the energy efficiency was evident from day one. The installation process was seamless and top notch professional. Thank you Astellite team!"

Frequently Asked Questions

What are the benefits of Astellite double glazed sliding windows?

Our sliding windows provide superior thermal insulation, noise reduction, and storm resistance while maintaining a sleek, modern look. They’re also easy to operate, low maintenance, and built to withstand Melbourne’s climate.

How do double glazed sliding windows improve energy efficiency?

The combination of German-designed aluplast uPVC frames and Lightbridge double glazing helps lock in indoor temperatures and reduce heat transfer. This contributes to lower energy bills and supports 7-star energy ratings.

Are Astellite sliding windows secure?

Yes. All Astellite sliding windows come with Safetec burglary protection, strong locking systems, and ultra bonding stability, giving you peace of mind about your home’s security.

Do sliding windows suit all areas of the home?

Absolutely. Sliding windows are versatile and ideal for bedrooms, living areas, and kitchens. Their smooth horizontal glide makes them perfect for spaces where swing windows aren’t practical.

What’s the difference between double glazed and triple glazed sliding windows?

Double glazing uses two panes of glass for insulation, while triple glazing adds a third pane for even greater energy efficiency and noise control. Both are available with Astellite sliding windows, depending on your needs.

How durable are uPVC sliding windows compared to timber or aluminium?

uPVC sliding windows won’t rust, corrode, or rot. They’re UV-stable, storm-resistant, and require minimal upkeep compared to timber or aluminium frames.

How long does installation take?

Installation time varies depending on the size of your project, but Astellite is known for its fast turnaround and meticulous craftsmanship. We’ll give you a clear timeframe during your free quote.
