On the interior, 3mm thick white polyurethane encapsulates and protects the strong timber core. The stylish white Everfinish and smooth rounded corners contribute to an elegant and contemporary look. The outstanding qualities of the hardwearing polyurethane material make this roof window virtually maintenance-free.

• Abrasion and impact resistant: Compared to plastic, polyurethane offers superior impact resistance. 
• Oil and solvent resistant: Polyurethane has excellent resistance to oils, solvents, fats and greases.
• Weather resistant: Polyurethane has outstanding resistance to oxygen, ozone, sunlight and general weather conditions.

The new roof window (GGU) is also ideal for bathrooms and other high humidity areas as it is extremely easy to keep clean by just wiping out the water.
