How do I take care of my windows/doors?
All our Lumi products are high quality, durable and low maintenance. We recommend you clean any frames, painted or foiled surfaces once a month with a soft camel hair brush, then wipe down with a soft cloth soaked in warm water and a mild detergent. You should not use any abrasive or chemical products on your Lumi products. If you follow these steps, your windows will look as good as new for years to come.
Where can I see your windows?
We recommend you contact us for more information about windows in your area. We have over a dozen regional sales managers covering the whole of the UK and Ireland, each specializing in their own area, who would be happy to help you find showrooms and installers in your area.
What are the advantages of fibreglass windows?
Fibreglass is an excellent material that can bring many strengths and advantages. It is one of the most energy efficient materials on the market, contributing largely to the low U-values of our windows. It is also incredibly low maintenance, capable of lasting a lifetime with proper care. Its strength, durability and low weight pairs perfectly with our innovative design, allowing us to create larger than average windows, minimizing sight-lines and maximizing glass, without compromising on stability or security.
What experience does your company have in the industry?
While we have only recently expanded into the window industry, we are far from inexperienced. We have been manufacturing high quality, bespoke composite doors for well over a decade under our Diamond and Apeer brands, growing continuously into one of the largest composite door manufacturers in the UK. This experience in both manufacturing and design has proven invaluable in the establishment of Lumi, fueling our innovation and ensuring we have a consistent, high quality product.
Is Lumi suitable for coastal builds?
The Lumi system was designed with coastal builds in builds in mind. The all-glass external finish and weather-resistant fibreglass frame seal away the internal components, protecting them against the elements, making the Lumi system perfect for dealing with the harsh, salty air and extreme weather that commonly batter coastal properties.
