Ridge & external finish
Discuss Classic or slimline ridge styling, roof colour and optional decorative cornice. The detail should work with your home’s windows, doors and roofline.

Ultraframe Classic glass roof
Light above. A room that works below.
A glass roof makes the garden and changing sky part of your room. The Ultraframe Classic system offers a flexible starting point for traditional and contemporary designs, with different roof shapes, finishes and glazing specifications.
We plan the roof around your property and the room beneath it. That means considering structural support, drainage, ventilation and the glass specification together, whether you are creating a new space or improving a conservatory you already have.
An insulated internal pelmet
A plastered perimeter can give the room a more finished feel while leaving the centre glazed. Ask about suitable downlights and the electrical work needed.
Designed for your location
Ultraframe’s roof design process accounts for location-specific wind and snow loads. Our survey establishes the dimensions, supports and installation details for your home.
Ambience glass by TuffX
Choose the view. Compare the performance.
Glass choice affects colour, glare, daylight and solar gain. These digital tint samples let you explore the Ambience range and carry a preference into your roof design.
Illustrative screen samples only — not photographs of physical glass or a calibrated simulation. Real glass changes with the light, viewing angle and sealed-unit build-up. Ask us about physical samples before making a final choice.
Ambi-Blue
A gentle blue tint with a brighter outlook than the stronger solar-control options.
Ambi-Sunshade Blue
A stronger blue solar-control option for comparing heat rejection with available daylight.
Ambi-Aqua
An aqua tint offering strong solar control with a different colour character to blue.
Ambi-Neutral
A subdued neutral appearance when you prefer less obvious colour in the roof.
Ambi-Bronze
A warm bronze tint to compare alongside traditional frame colours and finishes.
Ambi-Ultra
A very dark tint with high solar rejection and substantially less daylight transmission.
Ambi-Satin Privacy
A privacy option with a translucent appearance. Ask us to confirm the proposed glass build-up and its performance.
Ambience roof glass comparison
Each row refers to the exact double-glazed build-up shown. Low E and Low E+ are different specifications; do not assume that every unit with the same tint has identical performance.

*TuffX’s published term. Figures checked against the manufacturer’s product information on 2 October 2026. These are glass-unit values, not whole-roof U-values or a guarantee of room temperature. Final glass specification, availability, size and roof-system compatibility are confirmed in your quotation.
How to read the figures
A lower glass U-value means less heat passes through the glazing under the stated conditions. A higher solar reflection figure means more solar energy is rejected. Light transmission tells you how much visible light passes through: higher is brighter. Consider all three together.
More than just a tint
Ask about Ambi-Max for larger panes, Ambi-Triple for a triple-glazed build-up and satin privacy combinations. These need a separate specification and compatibility check. Ambi-Clarity is a side-glazing product, so it is not listed here as a roof-glass option.

A clear scope from the start
New roof or a complete new room?
A replacement roof needs an assessment of the existing structure. A new room also brings foundations, walls, doors and finishing work into the design. We discuss the full scope before preparing your quotation.

Classic glass roof questions
Can I replace a polycarbonate roof with glass?
Possibly, but glass changes the loading. We inspect the existing frames, supports, base and roof layout before confirming whether a new glass roof is suitable and what supporting work is needed.
Which Ambience glass should I choose?
Start with the direction the roof faces, how shaded it is and how you use the room. Higher solar rejection can reduce solar gain, but a darker option also admits less visible light. Compare the figures and ask about physical samples.
Does self-cleaning mean maintenance-free?
No. The coating uses daylight and rain to help break down and wash away organic dirt. Its effectiveness depends on exposure and conditions; occasional cleaning and care in line with the manufacturer’s instructions can still be needed.
Is the glass U-value the U-value of the whole roof?
No. The comparison figures describe the named glazing build-ups. The complete roof includes frames, bars, edges and junctions, so its performance must be assessed separately.
Can I include an insulated pelmet and lighting?
Yes, an insulated internal pelmet can be considered as part of the design. It creates a plastered perimeter for a more room-like finish and can accommodate suitable lighting. We confirm the scope and electrical work in your quotation.
Will a new glass roof keep my conservatory comfortable?
The roof is one part of the design. Glazing, shading, ventilation, walls, doors, heating and orientation all matter. We assess the room as a whole rather than promising a fixed indoor temperature.
Can I use the visualiser for a quote?
Yes. Your roof shape, dimensions, bar layout, colour, ridge preference, pelmet choice and Ambience glass selection are included in the enquiry. The preview is a concept, with the final specification subject to survey.
