We use Granada for all of our secondary glazing needs. Their product range is HUGE and they usually turn quotes around within 24 hours. Their vertical sliding units in particular have a very thin and discreet profile which makes selling their products very very easy.

We've been using Granada Glazing products for about 4 years now on all of our secondary glazing installs (City Insulation Ltd). The range of styles is excellent so they discreetly match primary windows and the effectiveness at reducing external noise pollution is fantastic. Our customers are amazed at the level of noise reduction achieved, not to mention increased warmth within their homes which is so important as energy bills are rising at such rates. We wouldn't use anyone else!
