Lumen Rooflight cleans itself with Pilkington

27 February 2009

Manufactured in the Great Britain, the Lumen Rooflight offers a range of standard sizes and can fulfil bespoke applications to meet tight deadlines.

The Lumen rooflight meets with ISO 9001 and complies with British Standard 6375 Part 1: 2004 for weather performance. All Lumen rooflights are fitted with Pilkington Activ™ Neutral self cleaning glass and have an Argon gas filled cavity and Pilkington Optitherm™ S4.

Pilkington Activ™ Neutral Self cleaning glass uses natural daylight to break down organic dirt and when it rains, or when water hits the glass, the dirt is loosened (both organic and inorganic) and washes away. 

Compared with conventional glass, self clean allows the water to dry very quickly, reducing unsightly streaks or marks that will ensure the rooflight is easier to maintain, making it environmentally friendly. 

For energy efficiency, Pilkington Optitherm™ S4, an ultra low emissivity high thermal insulating glass, is added as standard to all Lumen products.  The Optitherm™ S4 glazing works by reflecting heat energy back into the building.  The transparent coating on the glass transmits heat from the sun and provides high light transmission to create a naturally lit, comfortable environment all year round. This ensures rooms can stay cool in the summer and warm in the winter - ideal for the British climate and weather conditions.

There is a big difference between an easy clean coating and a Pilkington Activ™ coating; although some rooflight suppliers may claim they are the same.   Unlike other factory applied coatings, Pilkington Activ™ will last the lifetime of the glass, removing any concerns you may have over access to reapply a coating after just a couple of years.  By using a natural dual action process to clean, it is therefore a more environmentally friendly option. 

The Lumen rooflight range includes the Lumen conservation rooflight; replicating an original Victorian design by featuring casements and a glazing bar for added strength. Designed to sit flush, this low profile rooflight meets conservation requirements as it remains in keeping with listed architecture.
