Ultra Performance Aluminium Windows

Not all aluminium windows are the same, so when buying new windows it is important to make the right choice. The Alitherm Aluminium Windows that we supply are designed to last and have a wealth of features not usually available with many other aluminium windows.

Our aluminium windows are made from the finest materials in a choice of styles –

• Picture window
• Bay window
• Side opening
• Bottom opening

We can provide any design or combination that you require. Leaded lights either square or diamond pattern and Georgian glazing bars are also available.

Choose Windows with Polyamide Technology

Aluminium is known for it's resistance to rust, rotting and distortion but the introduction of polyamide technology takes it to a new level. Polyamide offers greater thermal insulation and increased strength.

Duel Colour Finish

With this exciting development in aluminium window technology, you can now choose different colours for the internal and external faces.

For instance, if you are replacing wood frames, you may wish to have the exterior colour in brown, thus keeping to the character of the originals, and have white as your internal colour, or indeed any other combination of two colours.

Super Slim Profiles – Maximum Light and Strength

With the inherent strength of the aluminium alloy used in the construction of our windows, we are able to offer super slim frame profiles. These are very attractive to the eye and maximise the available light entering your home. They will transform your home both inside and outside while retaining all the benefits of double glazing.

Maximise Your Security

In today's security conscious world you can never be too careful. So with security in mind our windows have been designed to meet the standards of BS 7950. Locking handles come as standard and a choice of locking systems are available including:

• Multi Point Locks with shoot bolts offering maximum security
• Espag Locks or two point lock
• Cockspur or single point lock

Additional Security Features

All fixings used in the construction of the windows are either stainless steel, aluminium alloy or another suitable corrosion resistant material.

All opening vents are hung on concealed stainless steel variable angled friction stays and fitted with espagnolette type locking handles. To limit the opening of the vent, restrictor stays are also fitted.

To secure the glazing units, aluminium clip in beads and flexible gaskets both inside and out meet with the requirements of BS 6262 Code of Practice for Glazing for Buildings.

Your Comfort and Warmth

To keep out those other unwelcome visitors, bad weather and draughts, all opening windows are fitted with highly durable double weather seals. The weather sealing is capable of performing to the toughest rating required under the British Standard.
