Keylite Sun Tunnels

Keylite Sun Tunnels

In some homes, it simply isn’t possible to install additional windows or roof lights. Maybe the space is too confined, or there are beams, wiring or other obstructions in the way. But luckily, there is an excellent alternative to bring beautiful natural daylight into any room. If your interior spaces are in need of more light, and there is simply no room for conventional glazing elements, then a high-quality sun tunnel could be the perfect solution. Sun tunnels feature a highly reflective internal tubing that redirects sunshine from the external roof surface directly down into otherwise dark interior areas, allowing you to bring plentiful natural light into even the most hard-to-reach rooms and awkward corners.

At Roof Window Outlet, we’re proud to stock an extensive range of premier sun tunnels from one of the most esteemed brands on the market: Keylite. If you want to achieve a flawless finish and truly unbeatable light performance in your home, then Keylite is the number one choice. Here are just some of the many reasons why investing in a Keylite sun tunnel for your property could be one of the best decisions you’ll make.

Why Choose Keylight Sun Tunnels?

Discrete Design

As Europe’s fastest-expanding roof window manufacturer, Keylite is renowned for its elegant, subtle and streamlined designs. Offering a wide selection of rigid and flexi sun tunnel options in a broad range of sizes, Keylite has the ideal product to suit all properties – regardless of how awkward or restricted they might be. The revolutionary Keylite Sunlite Tube System range ticks all the boxes when it comes to intelligent, low-profile design and exceptional performance.

Enabling homeowners to channel beautiful natural daylight into even the most problematic corners where conventional windows just couldn’t be fitted, the Sunlite system is perfect for both flat and pitched roofs between 15 ̊ and 60 ̊. With numerous sizes to choose from, including 35 cm, 45 cm, and 53 cm options, you can select the perfect sun tunnel for your exact needs. Suitable for neat installation into tiled and slate roofs, the Sunlite system will blend seamlessly into your roofline for a subtle, discrete finish.

Unbeatable Performance

The Sunlite Tube System comes in two varieties: rigid and flexi. Keylite’s rigid sun tunnel comprises a highly durable, mirror-polished aluminium light tube with an unbeatable Alanod Miro Silver finish, allowing an incredible 98% light reflectance – simply unrivalled. This rigid tubing enables highly efficient illumination with minimal transmittance loss. It’s also extremely robust and will never lose its reflectance over time.

Keylite’s flexi sun tunnel, like Keylite Flat Roof Polycarbonate Sun Lite: Flexi System, is designed for homes where obstructions preclude the installation of a rigid tube, meaning even the most awkward, out-of-the-way corner could soon be flooded with plentiful natural sunlight. The flexible tubing is perfect for problematic areas and still offers an impressive 83% light reflectance.

Added Extras

Keylite doesn’t just deliver unbeatable performance. Its sun tunnels come complete with a wealth of ingenious added features and benefits at no extra cost. The revolutionary Sunlite Tube System is highly efficient, quick to install and easy to clean. Keylite’s clever click-fit installation enables each sun tunnel to be installed into the roof far faster than many competitor products. In fact, most Keylite sun tunnels can be installed in just a few hours by a competent DIYer following the comprehensive instructions provided.

Every Sunlite model also incorporates integrated ventilation at both roof and ceiling levels, allowing homeowners to reduce condensation risk. Meanwhile, the innovative Self-Cleaning Glass ensures maximum daylight penetration without any maintenance required.

Trouble-Free Guarantee

When choosing Keylite, you’re guaranteeing yourself a fantastic finish. Over the years, this award-winning company has been recognised by an array of established industry bodies and companies, including the likes of the Builders Merchant Journal, Buildbase and Barratt Development.

Plus, this award-winning roof window company promises fantastic performance for years to come. Every single sun tunnel it produces comes with a 10-year manufacturer’s guarantee, so you can relax in the knowledge that you are making the perfect investment for your home.
