Add Value to Your Home

Your new room is a big investment and with Ultrasky you can ensure a good return on your investment. When extending your home, the amount of natural light flooding into the room is extremely important as bright spaces add much more value than dark spaces. The slimline look of Ultrasky in conjunction with the optimal fixed 25° pitch is perfect for drawing in natural light over a kitchen island or dining table.

Because it’s been thoroughly wind tested, you’ll be able to depend on your roof’s triple layer storm shield protection and reduced bar frequency to resist harsh weather.

The structural integrity of your Ultrasky lantern will be underscored by outstanding heat retention performance, which is made possible by its thermally broken components which also eliminate any risk of condensation.

When fitted in a 1000mm x 2000mm configuration, this rooflight can return a U-value of 1.1. This is just one of the many benefits that make the Ultrasky lantern roof an enduringly-popular choice for homeowners.

A Range of Options to Choose From

Our Ultrasky lantern can be customised by adding a manual or automatic roof vent. This will allow you to control the temperature of your room and filter out warm air that would otherwise convert into condensation.

Depending on your budget and design preferences, your rooflight can be clad in aluminium or uPVC – externally and internally. Whichever material you choose, you won’t need to compromise on performance.


Three Reasons to Choose the Ultrasky Lantern Roof

Uninterrupted Sightlines

Although looks won’t be your only consideration when seeking out a lantern roof, you want your new system to deliver outstanding aesthetics and market-leading performance in equal measure. The Ultraframe lantern roof succeeds on both levels and will bring any orangery, extension or flat roof to life.

The Ultraframe lantern roof uses fewer bars and more glazing. Not only does its design produce stunning minimalist sightlines, but it also captures and focuses the light from above, which is then redirected into the space below. Because it can span wide areas, it’s the perfect accompaniment for homes with lots of space.

Comprehensive Guarantee

Your Ultraframe Lantern roof will be designed to last. But we want you to buy your product with absolute confidence – so that, if the unexpected happens, you’re fully covered. That’s why your purchase will include a comprehensive 10-year guarantee as standard.

What does this guarantee cover? You’ll be protected against cracking, discolouration, component failure, cracking and shape deterioration. Please speak to your Ultra Installer to ensure they offer this level of guarantee for your lantern roof, for your peace of mind.

Outstanding Glazing Range

Your new Ultraframe lantern will reward you with superb thermal efficiency. That’s because the glazing used as standard in this system will deflect the sun’s rays during spring and summer while retaining heat when it’s cold – but without affecting light penetration.

This equates to a room that isn’t just lighter and brighter; it will also make your investment worthwhile, because you’ll be able to rely less on your thermostat to stay warm during colder seasons – which means your heating costs are likely to reduce.
