Powder coating
The lantern’s powder coated exterior doesn’t just offer a wide range of colours, it also delivers a thicker, more consistently smooth finish when compared to standard finish.
Powder coating results in an extremely durable finish and is also much kinder to the environment.
Self-clean glass
Once installed, your powder-coated, glazed lantern will be fully weather resistant, with self-cleaning glass to reduce maintenance even further.
Specially designed to remain cleaner for longer, our self-cleaning glass features a transparent coating that breaks down dirt using the sun’s ultra-violet rays, which is then washed away by any rain.
The highly durable coating is integrated into the external surface of the glass. It will still require the occasional clean in line with the glass manufacturer’s instructions, but at far longer intervals compared to conventional glass.
RAL
We offer more than 150 colours in matt, satin or gloss, including the option to have different colours on the inside and outside of the frames.
This gives you greater freedom to match both the interior and exterior style of your property.
