Accredited Double Glazing: Quality Products

From 1st July 2013 it became mandatory for manufacturers of windows & doors to apply CE Marking to their products. CE marking indicates that a product conforms to legal requirements in specific European technical standards known as harmonised European Norms (‘hEN'). It enables a product to be placed legally on the market in any European member state. However, regulatory requirements may differ from country to country.

What’s the difference between double glazing and triple glazing?

Our Declaration of Performance

A key part of the CE Marking process is that a Declaration of Performance must be produced by the window manufacturer. The Declaration of Performance details all of the essential characteristics of the product and enables the information to be available to the end user. The document has to be available in the public domain, so not only does the certification need to accompany the product it needs to be visible in places such as our website.
