Product knowledge

We look at everything to make sure you get the correct product for your project, to explain further ill use this example.

A property in a coastal area will need a window that holds a high resistance to sea water due to the high salt content in the air, this corrosive effect can destroy a window within 18 months or causes sealed units to become misty.

Or a aluminium bifold door can start to corrode within 6 months. Even worse the company who installed them will prove less than helpful when that time comes.
