What is ThermaTile®?
ThermaTile® is a conservatory roof conversion system for homeowners who want the look and feel of a tiled roof without losing the core structure and purpose of their conservatory. It is designed for existing conservatories where the roof needs a more solid, stylish and insulated finish.
The system uses lightweight composite slate tiles on the outside and CI Group’s specialist C.H.R.I.S® insulation system on the inside, helping turn a room that is too hot, too cold or rarely used into a more comfortable living space.
Is ThermaTile® the right option for your conservatory?
ThermaTile® is usually best suited to homeowners who want a more substantial transformation than internal insulation alone. It is designed for people who want their conservatory to look and feel more like a permanent part of the home.
ThermaTile® may be right for you if:
- You want a tiled conservatory roof appearance.
- Your current glass or polycarbonate roof feels dated.
- Your conservatory is too hot in summer or too cold in winter.
- You want to reduce glare and rain noise.
- You want the room to feel more like a proper living space.
- You want a roof system that includes specialist insulation.
You want a transformation that can usually be completed in a few days.

How the ThermaTile® system works
ThermaTile® is designed as a complete conservatory roof conversion. The existing roof is assessed, prepared and upgraded with a tiled external finish and specialist internal insulation. The result is a conservatory that looks more permanent from the outside and feels more comfortable from the inside.
Every ThermaTile® project includes C.H.R.I.S® internal insulation. This helps improve the comfort of the room while the external tile finish transforms the appearance of the conservatory roof.
Lightweight tiles with an authentic slate appearance
ThermaTile® uses lightweight composite slate tiles created to replicate the look of natural slate, giving your conservatory a smart, durable tiled finish without the weight of traditional slate.
The tiles are manufactured to provide strength, durability and long-term performance while remaining suitable for conservatory roof structures.

How ThermaTile® compares with other CI Group roof systems
What customers say about their conservatory roof transformation
What is ThermaTile®?
ThermaTile® is CI Group’s lightweight tiled conservatory roof conversion system. It combines lightweight composite slate tiles with C.H.R.I.S® internal insulation to create a more comfortable, more permanent-looking conservatory space.
Is ThermaTile® the same as conservatory roof tiling?
ThermaTile® is CI Group’s branded tiled roof conversion system. It is more than simply adding tiles, because it includes the external tile finish, internal insulation and ceiling finishing as part of a complete conservatory roof upgrade.
Can ThermaTile® replace a glass or polycarbonate conservatory roof?
Yes, ThermaTile® is designed for conservatories with older glass or polycarbonate roofs, subject to survey and suitability checks.
Will ThermaTile® make my conservatory warmer in winter?
ThermaTile® includes C.H.R.I.S® internal insulation, which is designed to help improve comfort and reduce heat loss through the roof.
Will ThermaTile® make my conservatory cooler in summer?
ThermaTile® helps reduce the extremes of heat caused by direct overhead sun, making the room more comfortable during warmer weather.
Will I lose natural light?
ThermaTile® changes the roof from glass or polycarbonate to a tiled external finish, so the room will receive less overhead light. However, your conservatory will still benefit from side windows and doors, and the internal ceiling finish is designed to create a bright, clean look.
How long does ThermaTile® take to install?
ThermaTile® installations are typically completed in 2-3 days, depending on the size, shape and condition of the conservatory.
Does ThermaTile® include internal ceiling finishing boards?
Yes. The internal roof is finished with ceiling boards to create a clean, completed look inside the conservatory.
Is ThermaTile® suitable for every conservatory?
Most conservatories can be assessed for a ThermaTile® conversion, but suitability depends on the existing frame, roof structure and condition. A survey confirms the right approach.
How much does ThermaTile® cost?
Every ThermaTile® quote is tailored to the individual conservatory. The cost depends on the size, shape, structure, current roof type, finish and installation requirements. CI Group does not advertise standard website pricing because every project is different.
What is the difference between C.H.R.I.S® and ThermaTile®?
C.H.R.I.S® is an internal conservatory roof insulation system installed beneath the existing roof. ThermaTile® is a tiled roof conversion system that changes the external roof appearance and includes C.H.R.I.S® internal insulation.
What is the difference between ThermaTile® and SkyTherm®?
ThermaTile® creates a lightweight tiled conservatory roof appearance. SkyTherm® creates an orangery-style roof with a flat roof, roof lantern or flat rooflight.
