uPVC Lift & Slide Doors Double Glazed Perth

On average, the Kömmerling PremiDoor 76 (PD76) achieves a 1.4 U value, making it incredibly advanced in thermal performance compared with the standard offering of single-glazed windows and doors in Australia.

Utilising energy-efficient glass options in our lift and slide door configurations provides many benefits once installed, including noise reduction, energy efficiency, increased safety, reduced condensation, and reduced heat transfer. This helps to keep your home naturally cooler in summer and warmer in winter, helping you to save on energy bills.

Most sliding door systems in Australia are fitted with brush piles as a type of seal. Although the lift and slide door utilises brush piles in some parts of the door, the sliding panel is fitted with rubber seals which are compressed when the door is in the locked position – this is one of the features that allows the product to provide enhanced security and perform so well thermally.

While standard sliding doors sit permanently on rollers, lift and slide doors use a unique handle system. This means when the handle is turned 180°, the internal gearing lifts the door panel upward, disengaging the weather seals from the track, and allowing the glass panel to be moved easily. When the handle is returned to the original position, the door is lowered back onto the track and is locked in place by its own weight. 

Yes – and not only due to the double glazing. Standard sliding doors use brush seals that must be loose enough to allow the door to slide. This often leads to minor air leaks, which reduce home conditioning (air conditioning or heating) effectiveness. However, as lift and slide doors physically drop into the track, the weight of the door compresses the high-quality rubber gaskets against the frame, creating a hermetic seal that provides stronger thermal insulation – and soundproofing – than a standard door. 

Yes, lift and slide doors can support larger glass spans and heavier double-glazed units than traditional sliding doors. This is because when the door is moved, the weight is only on the rollers, not the frame or other components. This is a primary advantage of lift and slide doors, making these double-glazed units a popular choice for homes with expansive openings onto alfresco spaces, in which a door with a larger glass span maximises the view.  

Yes. Rather than sitting ‘on’ the track like regular sliding doors, lift and slide doors sit directly ‘in’ the track. Combined with their heavier weight, this makes lift and slide doors more difficult to lift out from the outside. When the door is in a ‘down’ position, this ‘weights’ it into a locked state. Additionally, our lift and slide door systems feature multi-point locking bolts that engage with the frame at several heights. The combination of track position, weight and double-glazing makes double glazed lift and slide doors one of the most secure door options on the market.
