Energy Efficient

The decorative super-insulated columns provide high levels of comfort and have a U-value of only 0.15 W/m²K. Our slimline ridges are 30% slimmer than traditional ridges and come with high-performance thermal breaks to prevent cold spots and condensation.


Our glass conservatory roofs have been weather-tested to ensure that they can withstand adverse weather conditions. Our glass conservatory roofs also fully comply with the latest Building Regulations and have been pre-approved by Assent and JHAI.

Structural Integrity

As a testament to their structural integrity, our glass conservatory roofs are BBA-approved and come with a 25-year life expectancy certificate. They have been wind-tested by Wintech at speeds of up to 130mph. Additionally, our glass conservatory roofs are leak-proof due to the Speedlock system, which also allows for the introduction of up to 15 bars.

Internal Pelmet

For space to install lights and speakers in an area that is conventionally difficult to light, our glass conservatory roofs consist of a vaulted ceiling and an internal pelmet around the perimeter.

Customisation Options

Our glass conservatory roofs come with various customisation options. You can choose between White, Satin Black, Anthracite Grey, or any custom RAL colour for the frames of your glass conservatory roof. Our glass conservatory roof comes with a choice between a classic ridge and a slimline ridge. The pitch of our glass roofs can be adjusted from 2.5° to 40.9° to suit any style of property.

You can choose between toughened and performance glass in sizes 24mm to 35mm, and in different colours including Neutral, Aqua, Blue, Bronze, or any bespoke colour. We also offer a one-, two-, or three-tiered cornice for a modern look or a curved cornice for a traditional look. They are available in four standard colours and any RAL colour. Our super-insulated columns are also available in different colours, panelling, and sizes.

Performance Glazing & Further Choices

Our performance glazing has a U-value of 1.0 W/m²K and has either high or low levels of solar rejection and light transmission depending on how much sunlight your home receives. It’s important to choose the correct specification for the orientation of your home. This results in the glazing keeping your room warm during the winter and cool in the summer.

Our glass conservatory roofs come with a myriad of choices to create a bespoke roof. In addition to the other customisation options already mentioned, we also offer a central lighting panel, crestings and finials, a roof vent,  and a choice between aluminium and uPVC for the frame of the roof.

Frequently Asked Questions

How much are glass conservatory roofs?

It is difficult to provide a price for your glass conservatory roof as various factors contribute to the overall costs, such as the size and any customisation options. For a quote, please call us at 01985 215566.

Does a glass roof make a conservatory more energy-efficient?

A glass roof will make your conservatory extremely energy-efficient and keep you warm. This is because of the chambered top caps that come with our roof, which provide structural integrity and prevent heat loss. Twin wall-chambered top caps also help enhance the thermal efficiency of our glass conservatory roof and prevent condensation from building up better than our competitors do.

Is your glass roof secure?

Yes, it is. The chambered top caps that come with our glass conservatory roof are a security feature as well because they are impossible to remove. This makes our glass roof a very safe option.

Does your glass roof have trickle vents?

Our glass conservatory roof comes with trickle vents to allow for a continual flow of air into your room below. This prevents moisture accumulation and regulates temperature so that your living space does not overheat.
