Astellite Double Glazed Windows: What Sets Them Apart and What to Expect
Astellite double glazed windows are designed, manufactured, and installed in Melbourne by a team that has been bringing European window engineering to Australian homes since the company was founded. Every product in the Astellite range uses German-engineered Aluplast uPVC profiles and high-performance Lightbridge double glazing, which are combined with precise custom manufacturing and professional installation to deliver consistent results across every project. This guide covers what makes Astellite double glazed windows different and what homeowners can expect from the product and the process.
What Goes Into Every Astellite Window
Astellite double glazed windows are built around two core components that together determine how well the window performs over its lifetime.
German-Engineered Aluplast uPVC Profiles
Aluplast is a German manufacturer of uPVC window profiles whose products are used across Europe in high-performance residential and commercial construction. The profiles used in Astellite windows feature five-chamber multi-chamber construction, which reduces heat transfer through the frame to a very low level. The material is UV-stabilised for Australian conditions, moisture-resistant, and engineered for a service life of over 30 years without painting, staining, or resealing.
The choice of Aluplast profiles reflects the same principle that shaped Astellite from the beginning: Australian homeowners deserve access to the same quality of window engineering that has been standard in demanding European climates for decades.
Lightbridge High-Performance Double Glazing
The glazing units used across the Astellite range are sourced from Lightbridge, an Australian glazing supplier whose products are specifically manufactured for the performance requirements of the local market. The combination of Lightbridge glazing and Aluplast profiles delivers window systems with the low U-values, appropriate solar heat gain coefficients, and high acoustic performance that Melbourne’s climate and the current NatHERS 7 star standard require.
Custom Manufacturing and Local Installation
Astellite double glazed windows are custom manufactured in Melbourne to your home’s exact opening dimensions. There are no standard-size units that need to be forced into non-standard openings. Every window is measured, manufactured, and fitted precisely, which means a tight seal, smooth operation, and consistent thermal performance across every unit.
Installation is carried out by Astellite’s own team, which means the same standard of care that goes into manufacturing the product is applied to fitting it. The team manages everything from site preparation through to final cleanup, and every installation is backed by a 10-year warranty.

Astellite manufactures a full range of window and door styles for residential homes in Melbourne. Window styles include tilt and turn windows, awning windows, sliding windows, bifold windows, fixed windows, bay windows, corner windows, and custom windows.
