How our warm roof is built

We build each roof around a lightweight aluminium structural frame with thermally broken rafters. The structure supports 90mm rigid PU insulation, a 25mm secondary insulation layer and a breathable membrane beneath lightweight composite tiles, effectively reducing heat transfer for year-round use despite the compact build.

Internally, 12.5mm foil-backed plasterboard finishes the vaulted ceiling, while over-soffit ventilation eliminates condensation. Every layer works in sequence to remove cold bridging and deliver elite insulation across the roof.

Building-regs-compliant thermal performance

Achieving 0.15 to 0.18 W/m²K, our warm roof systems easily exceed UK building regulations for thermal efficiency on conservatory roof replacement projects. They’re the perfect replacement for older polycarbonate or other faulty roofs.

Lightweight aluminium ring beam

A thermally broken aluminium frame weighs just 31-38 kg/m², letting roughly 9 in 10 existing conservatory frames carry the load without new foundations.

Advanced insulation materials, stacked

Primary 90mm PU board and a 25mm secondary layer sit above and within the frame, removing cold bridging and lowering long-term energy consumption.

Plaster-ready vaulted ceiling

Each roof arrives with 12.5mm foil-backed plasterboard internally, ready for plaster, recessed LED downlights and an insulated perimeter pelmet system.

Strength, security and weather resistance

The aluminium frame is tested against high wind speeds and snow loads, while lightweight composite tiles resist cracking and fading. Any integrated rooflights or lanterns use solar-control, self-cleaning glass, giving your customers a secure, weather-tight new roof in all conditions.

A straightforward like-for-like swap

Our warm roof is one of the easiest conservatory roof replacement options on the market. Around 90% of existing conservatory frames can support the lightweight aluminium structure, so most jobs need no new foundations or support legs.

Combining the aluminium ring beam, PU insulation and breathable membrane, the system fits Victorian, Edwardian, Lean-To, Gable and P-shape footprints with U-values from 0.15 W/m²K, a clear upgrade from any old glass roof or polycarbonate.

Had both front and back stable doors fitted recently, and I have to say the men that came to fit them were really good, pleasant, efficient and did a great job! I am really pleased with my doors and the way the men conducted themselves; they are a credit to Alpine – thanks again.

I can’t thank the team at Alpine enough for all of the hard work on your build. They were great from the start, being really helpful through the quote process and in advising. The fitting team worked so hard to make sure everything was perfect, and nothing was too much trouble. We are so happy with Alpine. The results really speak for themselves, and we would not hesitate to recommend them to anyone!

We recently renovated a small cottage and needed to consider the traditional look and feel of the property, Alpine Windows and Doors were brilliant, listening to our requirements, we ended up with 6 sash windows and a new composite door all in a non standard colour, which was no problem. from placing the order to the completion of the installation nice and smooth, 5 weeks time frame, fitted perfectly with our project, would highly recommend

Excellent service from start to finish. They made the process from colours to design easy, nothing was too much trouble. Lovely polite staff and fitters. Fitters turned up on time and finished to an exceptional standard (I am a perfectionist!) left my home clean and tidy and removed all old frames and doors. Couldn’t fault them at any stage and would highly recommend them. I would give more than 5* if I could.

Peter at Alpine has done the windows and doors at both our offices and my home. The service was very professional, fast and competitive price wise. I had a combination of Aluminium bi folds and French doors with UPVC windows. I cannot fault the quality. Very happy to recommend for both domestic and commercial projects.
