Window FAQs

How energy efficient are uPVC windows?

UPVC windows are highly energy efficient due to their excellent thermal insulation properties. They reduce heat loss and provide a superior barrier against heat transfer compared to traditional materials, helping to maintain a consistent indoor temperature while also reducing energy bills. UPVC windows are often rated A+ or A++ for energy efficiency, especially with double or triple glazing. By minimising air leakage and maximising heat retention, uPVC windows contribute significantly to reducing energy consumption. 

Are uPVC windows secure?

Yes, uPVC windows are highly secure. They are often double or triple glazed, making it harder for intruders to smash through them. Unlike wooden frames, which can deteriorate and rot over the years, uPVC can stand the test of time and continue to protect your home long into the future. For the finest security performance, opt for frames with robust locking mechanisms when choosing your window style.

How do I maintain and clean uPVC windows?

To keep your uPVC windows looking their best, start by wiping away any debris with a soft cloth. Then use warm soapy water to wash the frames with a non-abrasive sponge or cloth. Rinse thoroughly and buff dry. If you really want your windows to shine, cleaning with a vinegar-water solution (2 cups of water with ¼ cup of vinegar) works wonders. Always avoid harsh chemicals like bleach. Cleaning every couple of months will help keep your windows looking their best.

Can uPVC windows reduce noise pollution?

UPVC windows are excellent for reducing noise pollution. Their double or triple glazing and strong seals create an effective barrier against external sounds, making them ideal for homes in noisy areas. 

How do uPVC windows compare to other window materials, such as wood or aluminium?

UPVC windows offer several advantages over wood and aluminium windows. Unlike wood, uPVC doesn’t rot, warp, or require frequent painting, making it virtually maintenance-free and more durable in the long run. UPVC also provides better thermal insulation than aluminium, as aluminium conducts heat and cold more easily. While aluminium frames can be stronger and slimmer, allowing for larger panes of glass, uPVC windows generally offer a better balance of energy efficiency, cost-effectiveness, and ease of maintenance.
