Why add a roof lantern to your flat roof
We can use a versatile range of roof lanterns for flat roof projects. As the name suggests, a roof lantern will help to light up a glazed or brick built extension with a flood of natural light. Natural light from the sun is known to boost our mood and create a feeling of well-being. With a roof lantern from Global Windows, the benefits are more than aesthetic.
The versatility and superb functionality of roof lanterns has made them a hit with UK homeowners. Many people are now choosing them as the perfect conservatory roof replacement. Stylish in design, with excellent levels of thermal efficiency, it’s perhaps no surprise that their popularity has soared in recent years.

New Window and Window Swap
Had Global swap an existing window for a new bi-fold door and install a completely new window in our dining room. As hoped, both have created a lot of addition light. I have used Global in the past and would use again in the future. Professional service provided from the office staff. They were the only business I spoke to that was aware of the new building control regulations that were introduced at the start of October last year and therefore acted as Principal Designer keeping the works compliant. The guys that completed the work were very respectful, polite and tidied up after themselves. Would recommend.
