Energy Efficiency

The majority of our windows are A-rated for energy efficiency. They incorporate the very latest glazing technology and these double or triple glazed units use the latest clear energy glass.

In the UK, homes create a quarter of all CO² emissions. Our windows and doors will help to eliminate energy loss from your home as the units offer up to 3 times more thermal insulation than standard double glazing and are 20% better than Low-E thermally insulating glass. The outer pane allows optimal amounts of the sun’s energy through the glass into the room allowing the benefit of free solar heating. The inner pane uses an advanced glass coating technology which reflects the heat from inside the room back into the room. Our PlatinumNRG range of double-glazed PVCu casement windows achieve the ‘greenest’ Window Energy Ratings (WER) rating of A+ for energy efficiency.

The Window Energy Ratings scheme was launched in the UK by the British Federation of Rating Council, a Government-supported independent body, so consumers can reliably compare one product with another.

Eco-Friendly because aluminium is one of world’s most abundant, recyclable and sustainable building materials available

Our PVCu & Aluminium windows are both 100% recyclable & create energy efficient windows that exceed all current regulations.

Our PVCu windows are recyclable and 100% Lead and Calcium Zinc free. Our state of the art, intelligent design uses steel reinforcement in section under 1800mm and our recycling is done in the UK, reducing our carbon footprint


Here are Whiteline we re-cycle all our off-cut PVCu profile and Aluminium off-cuts and all our offices have paper recycling bins.
