Who We Help
For over 35 years, we’ve been working in partnership with housing providers, facility management businesses, and developers across the UK with bespoke windows and doors that deliver on quality, compliance, and long-term value.
Social Housing
From retrofit and regeneration to planned maintenance and capital projects, we specialise in supporting facility management businesses, local authorities and housing associations to deliver energy efficient and more sustainable homes.
We hold the relevant accreditations and support the delivery of work on projects supported by The Social Housing Decarbonisation Fund (SHDF), EWI and Warm Homes: Local Grant.
Every stage is expertly managed by our in-house team to ensure projects run safely, on time, and with minimal disruption for residents.
Commercial
Manufacturing and delivering specification-led windows and doors for commercial buildings of all sizes — from hotels to healthcare facilities, and offices to retail spaces.
Our work supports retrofit, new build, planned maintenance and capital upgrade projects, helping clients to modernise ageing assets with energy-efficient, compliant, and future-ready systems.
Trade
Supporting your projects with quality windows and doors, expert technical support, rapid glass replacement, and competitive trade pricing. We provide complete flexibility and customisable options, delivering on time every time, so projects run smoother and your customers stay happy.

What We Offer.
Manufactured in-house, every product is built to meet or exceed the standards of modern construction, from retrofit and regeneration schemes for social housing to large-scale commercial and modular projects.
Reliable, energy efficient, and easy to maintain, our uPVC window systems are designed to meet sustainability and compliance targets by reducing heat loss and improving EPC ratings.
Practical, secure, and versatile, our uPVC door systems are offered in a range of styles (including composite or bi-fold), providing solutions that suit both individual homes and commercial or public spaces.
Strong, slim, and thermally efficient, our range of aluminium windows helps to modernise buildings and maximise light, whilst reducing energy costs — ideal for projects that prioritise appearance and functionality.
Durable, secure, and stylish, aluminium doors are built to resist the elements and withstand heavy use — a sleek, practical solution for communal entrances and high-traffic areas.
Sleek and stylish, these modern glazed façades elevate the look of office blocks, retail stores, and high rise buildings, whilst also bringing light to shared spaces.
