Double Glazed Sliding Windows

Associations & Accreditations

At one time, sliding windows and sliding doors Melbourne were one of the most popular styles of window. This was when uPVC started to become the preferred material to fabricate windows. Without excessive maintenance, wood could not be made to slide and once uPVC hit the market, sliding was the feature that everybody wanted. It’s still popular today and many people prefer to install double glazed sliding windows throughout Australia when there’s limited space for a frame to swing outwards or if there’s a need for a semi-permanent flyscreen as the window is kept open for long periods of time in summer. This style of window works best for smaller apertures but can be fabricated to any size required.

Double Glazed Sliding Windows – A Classic Design with Modern Features

Early sliding windows had an inherent weakness at the point of the slide. UPVC window manufacturers didn’t try too hard to seal the area and they were known to let in draughts and in heavy rainfall, water could penetrate. Today, the designs have been tweaked and solutions have been created to close off these issues. The Ultimate double-glazed sliding windows have Double Weatherpile seals which are so good, that they block out heat in summer and the cold in winter. The windows are available in Low-E and opaque glass, utilising European hardware mechanisms and an advanced multi-point locking system. Furthermore, they are easy to clean and maintain with excellent sound reduction. We even include a flyscreen, just what you would expect from Ultimate Windows.
