Aluminium Windows Harlow & Essex

Aluminium is also a superb natural insulator. This means that our aluminium windows deliver fantastic energy efficiency, whereby they trap the warmth inside your home. These RAUM frames can attain U-values as low as 1.1, which is among the best any double glazed window can achieve. Your home will feel naturally warm, even during winter, which can lead to cheaper energy bills over time.

Our uPVC casement windows are designed to deliver an exceptional thermal performance. uPVC is a great natural insulator, and our frames are enhanced thanks to a chambered profile that improves its heat retention. The double glazing we use will work to trap the room’s natural warmth, keeping it at the optimal temperature all year round. This could save you money on your heating bills over time.

By working with Lister, we can offer our customers RAUM aluminium windows that come fitted with multi-point locking systems. This means they are protected at several different points around the frame, thus improving the consistency and overall standard of the window’s security. They can be designed to adhere to Secured by Design standards; the police preferred level of product security.

Aluminium has a much better natural lifespan than other regularly used window frame materials. RAUM support this with their ten year manufacturer’s guarantee, however these aluminium windows can often last much longer than that. If well maintained, aluminium windows can realistically last for around two decades before showing any signs of natural wear and tear.

Aluminium windows are traditionally finished in a matte anthracite grey. This can blend effortlessly with modern and traditional homes alike here in Essex or Kent. However, these RAUM frames are also available in a wide range of different colour finishes, thanks to the option of over 250 bespoke RAL colours. You’ll be able to create aluminium windows to suit your home perfectly.
