We have just had the windows installed throughout our new-build Passivhaus and are very pleased. They look fantastic - we went for the optional oak interior frame and black outside. The sound insulation is amazing and the quality very good.

ecoHaus really helped guide us through the deciding and ordering process, which helped a lot. And their aftersales has been excellent. We forgot to ask for keyed-alike doors but they have sorted it without hesitation. Really nice people to deal with and we are very happy.

When we saw the windows installed there was only one word to describe them and that was WOW!

We have 12 metres of floor to ceiling facing out onto our garden.

Its now 3 weeks ago and we are still amazed. The big sliders each of which weighs 220kgs have real momentum when you move them. The silence when they are all closed is almost deafening. We searched widely before deciding on who should supply for this spectacular eco build within a walled garden and there is no doubt we made the right decision and our very talented young architect agrees.

The whole process was smooth from start to finish and undertaken highly professionally by ecoHaus, who, if you are considering installing Internorm windows are the go to supplier.

ecoHaus recently fitted windows on our new build house. From the initial contact and design process through to the installation and aftercare we found the service to be open, honest and first class.

We are delighted with the results - the windows are high quality and value for money, making a real difference to the feel of our new home. Would recommend a visit to their Nailsworth showroom to find out more.

ecoHaus recently fitted the doors and windows on 3 contemporary new builds for me.

The end result is fantastic quality and value for money (which isn't the same as cheap!)

From the sales team working honestly and openly working through options, then the ordering and detailing team and finally the fitters, it has been a pleasure to work with them

I found ecoHaus on the internet after searching for triple glazed windows. As I was basically rebuilding a 1970's bungalow from the ground up I needed windows and doors for the whole project.

From the initial contact when I visited then showroom, through design, planning, delivery and commissioning, they excelled. Not only were the resales and technical staff responsive, the project manager and site teams were superb. These were all backed up by really good admin and client liaison.

The windows have now been fitted for around 15 months and they are brilliant. Couldn't be happier or recommend enough.
