Having such a large set of doors can raise the question of how to find a suitable solution for privacy, curtains may not be suitable, and blinds would just get in the way, that's why we offer a stunning range of integral blind options.  These blinds are installed inside the double glazed unit so they don't get in the way.  They don't need any cleaning either.  They operate in two ways, so you can choose to raise or lower the entire blind or you can tilt the slats so not only do these blinds look fantastic, they're really practical and useful as well.

Aluminium Bi-Fold Doors from Windoor Online Limited are designed with thermal efficiency in mind.  The profile utilises the latest polyamide thermal barrier technology.  This creates a thermal transmittance barrier between the cold outside and the warm inside keeping your home at a comfortable temperature.

The glass specification is equally important, after all, most of the door is made up of glass, we use softcoat glass, and we argon gas fill the units as standard.

Your new replacement Aluminium Bi-Fold Doors can be manufactured with double glazed or triple glazed glass units.  We use a range of high-performance glass solutions from Pilkington UK and Saint Gobain.  Our internally soft coated K glass offers excellent thermal insulation as the heat bounces off the glass and back into the internal living space.  As standard on our Bi-Folding Doors, we add Argon Gas to the double glazed units.  Gas is denser than air, which results in greater energy efficiency and a lower u-value.

In order to comply with building regulations, all Bi-Fold Doors will include toughened glass. Toughened glass is achieved by subjecting the unit to a heating and cooling treatment whereby high compression stresses are set up at the surfaces with balancing tensile stresses in the centre.  It’s primary benefit is that if broken, the glass breaks into none sharp pieces to reduce the risk of being cut by sharp broken glass.


If you’re aiming to improve security or achieve excellent noise reduction, Windoor Online Limited can offer acoustic laminated glass from Pilkington. The desired performance is achieved by combining various thickness of glass with a special polyvinylbutyral interlayer.


For something extra special, why not add integral blinds to your glass units.  You can choose from a number of different systems, including magnetic, solar powered and electric.  Discuss your requirements with us.
