Slimline Odd Leg Windows are becoming more popular with the growth in demand of properties such as Garden rooms, Static Caravans, Narrow Boats, Man Caves and Sheds

Our customers have a close affinity and sense of pride with these properties and are looking for solutions that are thermally efficient, maintenance free and slim sightlines. It is also expensive to ‘upgrade’ to the latest models or versions and as an alternative a more economical way of upgrading is to refurb – this is where double glazed doors come in!

Our products is a patent approved upvc system, which has been specially designed for the properties with narrow wall thicknesses.

Replacing old aluminium or single glazed windows and doors with new upvc odd leg double glazed windows and doors will not only give your property improved kerb appeal but will also have other added benefits – increased thermal performance and insulation as well as security being the most obvious advantages.

Fixing Methods

Screw Fix

If your wall construction thickness differs than required for aluminium fixing kits, or you'd prefer to trim the internal surround of the window with the existing timber or an new timber beading.

You can fix the windows and doors using screw fix through the depth of the window frame into the timber subframe of the window.

Simply open the vent and screw through the frame into the wall. Screws are not included. At least 50mm Screws required.

Aluminium Fixing Kit

Installed by knocking an aluminium fixing bar into the specially designed window, giving a secure clamp fix finish. 

The fixing bar then doubles up as an internal trim which sits flush to the inner wall.

This is suitable for wall construction of 38mm or 53mm.

The aluminium fixing kit is an additional charge on top of the standard screw fix offering. 

You will need to seal the odd leg frame (external lip) with non drying silicone sealant or a neoprene foam tape.

Odd Leg





Always measure from inside.

Remove any internal trim around the window to reveal the existing window. Simply measure the existing window. 

If the existing window is a very tight fit or you are measuring a new aperture, you can take the tight sizes (hole size) and reduce the overall size by 5mm - 8mm to allow for easy installation. 

Do not worry if you have rounded corners, these can easily squared off using a hand held oscillating saw. 

The corners do not need to be 'professionally squared' as the external overlap of the upvc window frame will cover the corners and therefore will not be seen.
