We are really happy with our PERFORMANCE windows and doors. They look great and passers by have even asked us about them!  The customer service has been amazing and the whole company and everyone we have dealt with have been a delight. The window fitting team were exceptional and really helpful on site.

Once the triple glazed windows were installed the house was immediately much warmer and more comfortable. The inside pane remains warm to the touch, which means that you don’t get draughts falling down the glass and into the room.

Nigel Banks – West Yorkshire 2016

I have worked with Green Building Store for many years, I’ve used them for my own home and I appreciate not just the products themselves but the helpful and supportive back-up.

Chris Morgan – Locate Architects 2016

We found everyone at Green Building Store to be very helpful throughout the project. They gave great advice and support, which was invaluable to novice self-builders like ourselves.

Client – Wales 2015

Green Building Store’s PERFORMANCE range offered the high performance we needed, combined with affordability.

Jonathan Barattini – Gale & Snowden Architect 2015

We got far more input from Green Building Store than we would get from other window suppliers and they very much worked with us as one of the team.

Eric Parks & Nittai Edelmann – Architects 2015

Cost-wise ULTRA came out better than other timber ranges we had quotes for and also the ULTRA windows looked aesthetically better than other similar options.

Marianne Heaslip – Architect at URBED 2015

We have been impressed with the level of support and service we have had from Green Building Store – including help with detailing and optimum installation of windows.

Marianne Heaslip – Architect at URBED 2015

Green Building Store’s PERFORMANCE range was by far the most cost-effective of all the quotes we received. They were of a high quality and the U value fitted the bill for the level of retrofit that we were aiming for.

Ian Mawditt – Bristol 2015

We have been very happy with Green Building Store’s after-sales service. There were no quibbles when we needed to replace a failed glazing unit and, while they were replacing it, the team also helped us adjust some of the doors in the house (fitted by another company).

Ian Mawditt – Bristol 2015

The PROGRESSION range is well suited for our newbuild projects. The modern aesthetic, quality and price very much appealed to us and our clients.

Charles Grylls – Dempsey Decourcy Architects 2016

We have found Green Building Store to be a very helpful company to deal with.

Clients – Hertfordshire 2016

The PERFORMANCE range was able to deal with our technical requirements, whilst also offering high performance triple glazing at a good price.

Chris Hales – West Sussex 2015

We really couldn’t fault Green Building Store. We found that even when a small mistake was made with a delivery it was quickly rectified and delivered the next day.

Angela Morley – Reading 2016

We knew we wanted triple glazing and to get it from a company that really cared about energy efficiency. Green Building Store were very knowledgeable about triple glazing and the PERFORMANCE range was also good value.
