Conservatory Roof Options:
for the Perfect Environment, All Year Long

Are you unable to fully enjoy and relax in your conservatory due to it being too hot in the summer, or chilly in the winter? If you have a glass or polycarbonate roof fitted on your conservatory then it might be time to upgrade to the Guardian Warm Roof!

The Guardian Warm Roof is an award-winning style of conservatory roof. Using innovative methods, it works to create the perfect environment inside your conservatory all year long. With clever technology and a stylish design, this type of roof is a fantastic choice for any conservatory.

The Science Behind the Guardian Warm Roof

Simply put, the Guardian Warm Roof is able to keep heat in when needed and stay cool in the warmer months.

The roof has a mixture of ventilation systems and insulation materials within it. By having each of them, the roof can keep a comfortable temperature all year round. A ventilated ring beam, waterproof plyboard and breathable waterproof membrane are installed first before any tiles are laid. The materials used within the roof allow adequate ventilation to eliminate condensation. Inside the conservatory, gaps between the rafters are left to provide ventilation. Under those timber battens comes 125ml of high-performance insulation, and aluminium tape is applied to the joints to ensure it remains airtight.

All of the materials used in the installation of a Guardian Warm Roof features an aspect of weatherproofing, meaning no unwanted draughts or stuffy air is being kept in the conservatory.

Why Choose the Guardian Warm Roof?

There are many benefits of having a Guardian Warm Roof installed on your conservatory, the fantastic thermal technology it provides isn’t the only one! The Guardian Warm Roof has a stylish design that can be customised to suit your individual needs or to match the aesthetics of your home.

The conservatory roof can be customised with various window styles and coloured tiles. It may be a solid roof, but you can customise it with a solstice skylight or roof windows to let light flood into your conservatory which will flow through your house. The windows can also have added accessories such as blinds, remote control systems and security locks for that extra privacy and safety. You can also choose the colour of your roof tiles or slates. The lightweight tiles come in various colours including Ebony, Antique Red, Moss Green, Charcoal and Burnt Umber. Guardian Slate is available in 5 natural colours Black, Brown, Grey, Mulberry and Terracotta. The various colour and texture options allow you to find that perfect match to your homes existing exterior and traditional or modern style.

Thermal science also helps you to save money on your energy bills! The Guardian Warm Roof is designed to be energy efficient and because of this, it has achieved a superior U-value (0.18 W/m.K in England and Wales and 0.15W/m.K in Scotland). This means that you won’t be wasting money trying to keep the room at a nice temperature throughout the year.

The Guardian Warm Roof can be installed on any conservatory roof style. Whether you currently have a Victorian, Combination, Lean-To, Edwardian or Double Hipped style, the roof is suitable for both standard and bespoke roof styles. Because of the pleasant environment it creates, you might even find yourself spending more time in your conservatory, making the most out of your investment.
