Aluminium Windows

Aluminium windows for a sleek, modern and long lasting solution.
Celsius Home Improvements do a lot more than uPVC windows. Discerning customers have been choosing aluminium for decades.

They are a long-lasting, cost-effective choice with very low maintenance, no rotting or warping and are B-rated energy efficient. Aluminium is also a sustainable resource - 100% can be recycled after its use.

Available in a choice of frame RAL colours you'll be able to select one that suits your home and style perfectly.

As with all our windows they are designed to significantly reduce heat loss and outside noise, keeping your home warmer and quieter all year round.

Remember all Celius products come with our 10 year guarantees!

Engineered to be greener

A number of factors influence the energy efficiency of a window. These include the profile system and the specification of the sealed unit. Windows are rated from A (no heat loss at all) through to G, the window Energy Rating label allows you to see, at a glance, how energy efficient a window is. Building regulations require that a window rated at C or above must be installed.

By using recycled PVC-U reinforcements instead of steel, wherever possible, we reduce our demands on natural resources, achieve better insulation and create a product that's actually stronger!
