Create A Stunning Roof Window Feature On A Budget

Vertical combiation skylights

Even small budget loft conversions or home extensions can have a stunning window feature thanks to RoofLITE's combi flashing kits.

Easy to install, the RoofLITE UCX combi flashing will create a perfectly weathertight seal for multiple roof windows. The stylish grey (RAL 7043) aluminium will complement your roof, and the weather and UV ray-resistant properties will ensure it will survive whatever the British weather throws at it.

A Smaller Budget Doesn't Mean An Unimpressive Finish

When you install 2 or more roof windows side by side or vertically, you can brighten your room, giving it the feeling of more space. And at RoofLITE prices, you can do so for much less.

It's so easy to do. Just follow the three easy steps below.

1. Choose The Design Of Your Group Installation

Simply decide on the design you would like (or have the space for) - 2 horizontal windows, 2 vertical windows or even 2 rows of 3 windows.

Your loft conversion company or home extension builders will be able to give you advise on what's possible with your roof structure.

Add value to your home

2. Choose The RoofLITE Windows You Want

RoofLITE windows are great value for money, and you can save money without compromising on quality.

Just remember that if you're creating a horizontal installation, you can have any combination of window widths but the heights must be the same. Vice versa, if you're creating a vertical installation, you can have any combination of window height but the widths must be the same.
