Go Green

Here at Atcost we strive to do our best for the environment.
With onsite recycling skips we separate all plastics, wood, metals and glass minimising the amount going to landfill.
We are also continually making the move to completely computerise our processing systems with the goal of running a paperless company.


For peace of mind and quality.

All of our window and door systems are made from the market leading names such as Rehau, Pilkington and Reynaers to name a few. Companies such as these are at the forefront of technology and development of their systems and are recognised as leaders world wide. We can assure you our products are designed to last.

Here’s a short little video we made ourselves as a little introduction to some of our products. It only took us 20 minutes to make and was initially a bit of fun but we will follow this up with new videos on each product and offer tips on maintaining your windows and doors.
