We have been really pleased with the quality of the ULTRA windows and doors from Green Building Store which have contributed to the overall energy performance of the project. Due to the success of this retrofit Passiframe now specifies Green Building Store windows and doors on all projects where possible.

Scott Adams – Passiframe 2020

I am already very familiar with Green Building Store’s windows and doors and know them to be good quality and robust..The clients are really happy with the windows and doors, including the big bi-fold doors, which really help bring the garden into the building.

Marianne Heaslip – Associate Principal URBED 2020

The ULTRA window range was the obvious choice for us. The U-values were in line with our needs and plans for Passivhaus certification. The support from Green Building Store was always first rate.

Rich Hibbert – Technical Manager PYC Group 2020

I’m always impressed with the quality of Green Building Store’s products, and the ULTRA windows and doors at Larch Corner are no exception. Without products of this outstanding calibre there is no way we would have achieved extraordinary standards of airtightness.

Mark Siddall – LEAP Architecture 2019

When it comes to MVHR systems for Passivhaus buildings, Green Building Store really understand the nuances and offer great support. I believe it’s their depth of understanding that makes working with them so incredibly effortless.

Mark Siddall- LEAP Architecture 2019

I have found everything to be spot on. The PERFORMANCE windows and doors are great. There have been no issues at all.

Pete Smith – Client 2019

We chose the PERFORMANCE range from Green Building Store because the clients wanted windows made from natural materials and the PERFORMANCE range offered good value for money for triple glazed windows. Green Building Store were very helpful with details and specification and were very thorough in putting together a comprehensive quote for the client and made ordering very efficient.

Sara Darwin – PHI Architects 2019

Thank you. We couldn’t be more impressed with the service we’ve had throughout from Green Building Store. You’ve been absolute professionals, really easy to deal with and all-round lovely folk!

Jo & Gail – Clients 2019

We specified the PERFORMANCE range because of its excellent value for performance and also because of  the quality of Green Building Store’s customer service. We did some cost comparisons and these windows came out really well compared to competitors.  Green Building Store is also very easy to work with and really supports us throughout the whole specification process.

Paul Testa – Architect 2019

During the whole of our major house refurbishment Green Building Store was the best company we dealt with, and indeed probably the best company we have ever dealt with in our life.

Alan & Monica – Clients 2018

We specify Green Building Store’s PERFORMANCE range of windows and doors regularly because they offer a good balance between cost and performance. They look great in our new office – we’re really thrilled with them.

Andrew Neal – Senior Architectural Technologist 2018

For me, achieving full Passivhaus certification on a retrofit project is the pinnacle of 20 years’ work and coincides with the length of my relationship with Green Building Store. Their products are often my first choice – not just because they offer excellent products but because their customer support – including the MVHR design service – and aftercare is second to none.

Gil Schalom – Architect 2018

Green Building Store’s AfterSales team were excellent …We really got the feeling that Green Building Store were on our side and batting for us. They have been a nice bunch of people to deal with.

Mark Watts – Architect & Developer 2018

I enjoy working with Green Building Store and Green Building Store windows and doors are our go to specification for high performance windows and doors. The combination of performance, cost and service is great, and difficult to find elsewhere.

Paul Testa – Architect 2018

We got a lot of technical advice and support from Green Building Store throughout our project. They are a really nice bunch of people and it has been a good experience to work with them.

Chris Copeman – Client 2018

Many thanks for the advice and care in designing the MVHR system. I’ve seen architects saying that Green Building Store are the most experienced suppliers in this field, but what they don’t say is how helpfully that expertise is provided.

MVHR Client – 2017

We’re very happy with the windows and doors – they look brilliant and are performing well. The service from Green Building Store, including fitting team and aftersales, has been fantastic. With windows and doors, it really matters to have a helpful and responsive supplier and aftersales team.

Will Anderson – Client 2017

Green Building Store were very helpful to deal with and very patient when I had to tweak the plans prior to ordering. I have already recommended Green Building Store to two other friends, who have been very happy with their windows as well.

Jerry Hooper – Client 2017

Green Building Store’s customer service was really good… We now specify windows from Green Building Store at every opportunity. It is good to be able to work with a supplier we can trust.

Tim Ratliff – Ratliff/Landells Architects 2017

We have a lot of previous experience of working with Green Building Store for MVHR design and supply and like working with them.

Dan Higginbotham – Parsons + Whittley Architects 2017

The PERFORMANCE windows are everything we wanted. They look great and we have not had any problems with them at all.
