It's a family business

We are a 100% family owned business, operated and controlled from our Suffolk based HQ. Since 2006, we’ve been supplying high performance eco-building products to the UK market. Now our main speciality, GreenSteps windows and doors represent the uncompromising high standards we strive for.

Windows and doors developed for tomorrow’s buildings

We are proud to have worked with the same production facilities for our windows and doors since 2008. GreenSteps windows and doors were developed by us specifically for the UK. Built to the highest performance standards, not specified down to a price level. Brought to you directly to keep prices low. Supplied to the lowest energy projects since 2008.

GreenSteps convictions walking the talk

All GreenSteps timber is sourced from sustainably managed forests. We only produce low energy products – with timber frames made for triple glazed units. Our office is triple glazed and super insulated. We use recycled Carbon neutral paper and our printing is done with vegetable based inks. We re-use our exhibition stands again and again. We believe in what we sell.
