Curtain walling was a bespoke solution usually reserved for larger commercial projects, the complex designs and high costs made them unrealistic for domestic use.  Nowadays however, more and more new build homes are being designed with large areas of curtain walling, in order to maximise light inside the property and create an impressive wow factor.

It's important that you consider the wind loading and structural suitability for any new curtain walling product.  We work with surveyors / draftsmen who specialise in this type of work and we would always carry out a detailed technical survey prior to completing any curtain walling project.

Your new replacement Aluminium Windows 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.


In some cases Windoor Online Limited will add Argon Gas to the double glazed units.  Gas is denser than air, which results in greater energy efficiency and a lower u-value.


If your home has windows that are low to your internal floor level, Windoor Online Limited, will instinctively upgrade your windows to include toughened glass. Toughened glass is achieved by subjecting the unit to a heating and cooling treatment whereby high compressive 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 bathrooms, dressing rooms, or perhaps just windows that are overlooked, you can choose from a range of decorative obscured glass.  We offer every pattern available in the Pilkington obscured range.


You can relax as all our aluminium windows and installation are covered with an 10 year insurance backed guarantee (IBG) with HomePro against defects and malfunctions so you have nothing to worry about.
