If you measure environmental impact on energy efficiency then our product is one of the highest performing conservation style rooflights available. Whilst some of our competitors products achieve the required standards of BS6375 it is worth asking exactly how each product performed under test conditions as there are many variables within the test that will differentiate between an average performing rooflight and an excellent one. We are proud to say that the Lumen range of steel rooflights achieved the highest class 4 rating for air permeability. Our full test report can be downloaded on the website along with an explanation of each test. As a result of the test performance achieved by the Lumen, we can say with confidence that our product is also one of the most energy efficient rooflights you can buy.
In addition to our excellent performance, we have decided to keep our manufacturing based in the UK. Whilst this has the obvious benefits of having control over our quality and development there is another factor that should be considered. Whilst our competitors are happy to boast of energy ratings or applaud the government's objectives to reduce carbon emissions; importing products from their factories in the Far East or Eastern Europe by plane or truck actually helps to increase the carbon footprint produced by those products.
Whilst we still have a long way to go ourselves, we are doing what we can to keep our environmental impact to a minimum and support organisations such as SPAB, The Woodland Trust, Weald & Downland Museum and World Wildlife Fund to ensure that both our built and natural environments are continue to thrive.
Pilkington Activ Neutral is the attractive neutral coloured glass that combines dual action, self cleaning properties with solar control performance. Neutral is a revolutionary glass that is perfect for use in both the roof and verticals. Pilkington Activ Neutral Self-Cleaning Glass uses the forces of nature to maintain its clear appearance without leaving unsightly streaks. In a dual action process organic dirt is broken down by daylight and is then washed away by rain, thus making it environmentally friendly and very easy to maintain.
There are a number of benefits offered by Pilkington Activ neutral glass compared to other spray on coatings. Activ Neutral will not scratch off and therefore you do not need to worry about re-applying in the same way that a rain racer coating would. Pilkington Optitherm S3 is an ultra low emissivity, high thermal insulating off-line coated glass. The effect of the low emissivity coating is to reflect heat energy back into the building. The transparent coating also transmits heat from the sun and provides high light transmission to create a naturally lit, comfortable working environment.
