Upgrade Your Conservatory with an Ultraroof Warm Roof Conversion
If your conservatory is too hot in summer and freezing in winter, you’re not alone. Many Sussex homeowners are finding that their once-loved conservatories just don’t perform like the rest of their home.
The good news? You don’t need to start again. With an Ultraroof warm roof conversion, Sussex Window Works can turn your existing conservatory into a beautiful, energy-efficient living space — quickly and affordably.
What Is an Ultraroof Warm Roof?
Ultraroof is Ultraframe’s most advanced solid tiled roof system, purpose-designed for conservatory roof replacements and new extensions.
Unlike older glass or polycarbonate roofs, Ultraroof combines super-insulated panels with a lightweight structure that looks and feels like part of your home.
Key Benefits:
-
Fully Building Regulations–compliant — your conservatory can become a real room again.
-
Exceptional insulation — U-values as low as 0.15W/m²K keep you warm all year round.
-
Lightweight design — often fits onto your existing conservatory frames or footings.
-
Customisable finish — tile colours, internal pelmets, roof lights, and plastered ceilings.
-
Quick installation — typically completed within a few days.
How a Warm Roof Conversion Works
A warm roof conversion involves removing your existing glass or polycarbonate conservatory roof and replacing it with a high-performance Ultraroof structure.
In many cases, we can retain your existing base and walls, subject to survey — making it an ideal upgrade that minimises cost and disruption.
The process:
-
Survey & structural check – we assess your existing conservatory.
-
Removal of old roof – safely dismantled and recycled where possible.
-
Ultraroof installation – precision-fitted panels with integrated insulation.
-
Finishing touches – internal plastering, lighting, pelmets, and external trims.
The result?
A warm, bright, solid-feeling room you can use every day — perfect as a kitchen extension, dining room, home office, or snug.
Ultraroof vs. Traditional Roof Systems
| Feature | Ultraroof | Traditional Roof |
|---|---|---|
| Installation time | 2–5 days | Several weeks |
| Insulation | U-value ~0.15 | Often 0.25–0.3 |
| Weight | Lightweight panels | Heavy tiles |
| Appearance | Custom tile finish, optional skylights | Requires full build |
| Planning requirements | Usually permitted development | Often requires approval |
With Ultraroof, you get the look and feel of a traditional extension without the cost or hassle of a full rebuild.
