Benefits Of Our Metal Windows Over Traditional Steel Windows

When replacing old metal windows, people want their new windows to be an improvement on the old ones. For people living in Listed Buildings or Conservation Areas, consent is required, and will not normally be permitted, especially if your looking to install the latest energy efficient PVCu windows. It is very important that your new replacement windows maintain the character, traditional styling and integrity of your property. When replacing your metal windows, especially traditional steel windows this can workout to be exceedingly expensive. Look no further because we have the perfect solution with our aluminium ‘steel-replica’ windows.

Aluminium is much more thermally efficient when compared to steel windows, highly secure, very sustainable, endlessly recyclable and is a fraction of the cost. Aluminium is a premium product, maintenance free and built to last, with the life span of aluminium windows being measured in decades rather than years.
