Developers in London & Home Counties

Developers can come to Window Projects for their premium installer. Of course, we’re more than just your local window and door installer. We’re a significant business with our hands in residential, commercial, and public projects. We have Certass accreditations so developers can be sure that we’ll know building codes and government mandates inside and out, whether it’s windows or doors, curtain walls or cladding. For health and safety, we offer welfare for scaffolding work.

Government standards are rising in multiple areas. Developers now have to ensure energy efficiency and accessibility while balancing concerns about longevity and maintenance costs. However, at Window Projects, developers don’t have to sacrifice design for efficiency. Almost all of our products have a wide variety of RAL colours or wood finishes.

Window Projects are registered members of the GGF. Developers can have peace of mind knowing this, as certification means we’re compliant with GGF’s conciliation services and the standards they uphold.

For large scale refurbishment, we have FENSA approval and can offer updated materials and even remove asbestos.

Commercial & Public Projects

Window Projects offers developers a wide variety of options for their new builds in commercial and public sectors. Commercial and public sectors must meet certain standards for energy efficiency, longevity, and improved ventilation.

We have aluminium and PVCu window options for casement, tilt & turn, or sliding sash styles. You can order these in almost every size available. Although Window Projects provides developers with double glazing as standard, we always recommend triple glazing for improved thermal efficiency.

Schools, hospitals, and commercial projects have unique challenges when it comes to maintaining internal temperatures. That’s why we offer window options for solar control, reduced glare, and noise reduction. To ensure low maintenance, developers can get self cleaning glass.

Safety and security are important to developers looking to build public and commercial projects. Ask us more about locks and toughened glass.

For residential and domestic projects, developers can rest assured we will meet their design. Almost all products come in modern and heritage styles, like our flat skylights or our flush casement windows. Developers can find the full range of RAL colours for their windows and doors.

We can best advise you about which window or door style works best for your project when you call us. Sliding sash windows are our most cost effective option for large scale projects. Now, with improved materials and double glazing, you can be certain of their energy efficiency.

Our doors are more secure than ever with multi point locking systems. We also offer lowered thresholds for doors of new builds to improve accessibility for wheelchair users and those with reduced mobility.

Window Projects offers developers premium features like bifold doors, French doors, roof lanterns and more.
