PVCu / uPVC Windows and PVCu / uPVC Window Installation
by Sky Windows, Wales

Why choose PVCu / uPVC Windows?

Waterproof and weather resistant
Unlike timber and metal, PVCu windows do not rot, crack, warp or rust when exposed to the elements for years on end. It is very durable and has a very long working life.

Low maintenance
PVCu windows do not require any major maintenance, regular painting or weatherproofing to provide you with years of trouble free service. A general wipe over with warm soapy water is all that is required to keep your frames looking like new.

Excellent thermal insulation
The multi-chambered design used in the construction of PVCu window frames whilst adding overall strength also helps to greatly reduce any heat loss through the frame.

Less of an impact on the environment
PVCu windows leave trees standing and PVCu can be melted down and recycled for use in the manufacture of other products.


Sky windows are made from 100% lead-free PVCu – better for the environment and better for you and your family. You no longer have lead in your petrol or paint, so why choose to have windows containing lead?

Energy Ratings explained

One of the most effective ways you can save energy within your home is through installing energy efficient doors and windows. Whether double or triple glazed, Sky windows outperform most of the other leading windows in the UK – mainly due to our innovative PVCu multi-chambered profile design. The BFRC Energy Rating Scheme is the UK’s national system for rating the energy efficiency of windows and is recognised within the Building Regulations as a method of showing compliance for your windows installation. The rating scale runs from A+ to G, and indicates how well a product will: • help you contain and conserve heat within your building in the winter • keep out the elements • resist condensation on the inside • contribute to improved sound insulation. Sky windows and doors can achieve an ‘A+’ rating*, better than most of its competitors, which means you’ll be able to enjoy a warmer and quieter home as well as lower energy bills. *Individual stockists may offer different ratings

EnergyPlus – setting new standards

The Sky EnergyPlus range offers even greater energy efficiency for your home. With a unique six-chamber PVCu profile that’s fully compatible with other Sky ranges, EnergyPlus profiles can achieve an A+ rating without the need for expensive low-iron glass on the outer pane of glass or the need for costly thermal inserts.

What’s more, EnergyPlus profiles can achieve a Window Energy Rating of a staggering A+12*. The additional chambers designed into the PVCu profile when it’s manufactured prevent less cold air entering your home, and less warm air leaving it.

Why pay to heat your home, then lose up to 20% through your windows and doors?
