The roof window frames are manufactured to ISO 9001 using robust 3mm Zintec* steel which is then polyester powder coated in RAL 9005 matt black as standard although other colours are available upon request. All of our roof lights offer a high specification of glazing that incorporates a 4mm toughened safety outer leaf with ‘Pilkington Activ’ self-clean, a 16mm argon gas filled cavity and a 4mm inner leaf of Pilkington K toughened.

The units are bedded and fronted by hand, using silicone to resemble the traditional putty appearance so often found on original Victorian skylights, In addition, all of our sky lights are supplied with a solid ash interior liner and a solid brass or chrome winding mechanism.
