Double Glazed Windows

Window Energy Performance

A window's energy performance has traditionally been stated in terms of its U-value.

However, manufacturers may quote the U-value of the frame, the sealed unit or the whole window - the performance of different products may not be readily comparable.

Whole window U-value calculations, while clearly more useful, are complex to determine because they must include the thermal performance of a number of components.

Wedlock Windows Ltd can offer you A Rated windows at very reasonable prices.
