Aluminium Double Glazed Windows

Why use Aluminium Windows for your Home?

Although uPVC is still a very popular option it is very worthwhile to consider using a lightweight metal such as aluminium in the frames.

Older designs had real problems with internal condensation on the frames but nowadays modern design & manufacturing techniques have eliminated all the “bugs” and what you get for your money is an excellent product.

The installation can be fitted direct to the opening or you can opt for a wood sub-frame (normally hardwood), on real terms the difference is only visual and can come down to the individual preference of the clients. They do have, however, some particular advantages over uPVC Windows when it comes to design & appearance.

• Very slim frames with up to 30cm Panel heights
• No bending, twisting & Warping over time
• Amazingly strong – great for home security
• No colour fade, rust or rot
• Flame proof (unlike plastic!)
• You can find more than 400 colours & shades
• Maximised acoustic & thermal insulation

Differences in Thermal Performance

Basically, you should opt for the best rated windows that you can buy for your money, broadly speaking that means opting for a window design that reduces the flow of heat or cold from one side to the other and is generally mentioned as the “U-value”.

• Uf: U Value of the frame with no glass.
• Ug: U Value of the glass.
• Uw: U Value of combined frame & glass.

As you can see from the pictures the internal design of the frames has a big impact, the second has more chambers, more insulation, warm edge spacers & triple glazing, but as you would expect, higher performance usually comes with a higher buying price.
