Is your product environmentally friendly?
There are many factors that can determine how environmentally friendly a product is. About 20% of the steel used in our Lumen roof lights is recycled. Whilst this amount may seem low compared to other manufacturers it ensures that the quality of the material used in the Lumen range of steel skylights is always high. By using a better quality steel you can be sure that the product you are purchasing will last a long time and therefore reduces the need to use more material replacing it in a few years. 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 explaination 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.
Do you have any advice concerning rooflights in a coastal location?
We produce the rooflights to the very best of our ability. As such we are proud to offer our customers an exceptional guarantee. Whilst the guarantee gives assurances about our commitment to you and the quality of the product, there are some exemptions. Firstly the location of your property is very important. Our zintec rooflights are treated with an Interpon APP120 primer before the application of a Cromadex Extra Life coating system for C3 Environment. As well protected as our products are the harsh salty environment of a costal location is likely to result in the faster deterioration of the protective coating and ultimately the metal. As such we do not recommend installation of our standard range in coastal regions or areas which are subject to a corrosive or polluted environment. If your property is located in one of these areas, please talk to us about our range of paint options or stainless steel rooflights. As with almost all exterior building materials, you should undertake regular maintenance to ensure that the product continues to work efficiently. We supply a copy of our guidelines with the order but please contact us on 0845 050 8746 should you require additional copies. Paint standards - ISO 12944 Paints & Varnishes - Corrosion Protection of Steel Structures by protective paint systems (parts 1-8) (1998) ISO 12944 Classification C3 = Urban and industrial atmospheres. Moderate sulphur dioxide levels. Production areas with high humidity C3 definition of coastal is less than 5000 metres from the sea.

How do I maintain my roof light winders?
Manufactured in the UK our winders are produced using CZ121 brass as this offers excellent corrosion resistance. Over time the colour may start to dull and so it is advisable that winders are checked and cleaned on a fairly regular basis to ensure smooth operation. Before cleaning, examine the item for damage. Surface dirt can often be removed using a very soft toothbrush or artist's brush. There are two ways to remove accumulated surface grime. The first is to use lukewarm distilled water with a mild liquid detergent and a soft cloth. Be careful to avoid scrubbing too hard because this may scratch the surface if there are particles of grit in the cloth. Rinse with distilled water and allow to air dry on paper towels. If this is not sufficient, greasy residues can be removed with a mixture of equal parts distilled water and alcohol. This can be applied with a stencil brush, cotton swabs or a soft cotton cloth. Rinse in distilled water and let dry. Polishing will remove tarnish. Because all metal polishes contain abrasives, they will also remove some of the metal. Over-polishing can, therefore, result in the loss of surface detail. If excess metal polish has been used in the past, there may be a build-up of residue in detailed areas. This is usually greyish-white or greenish-white in colour. Such residues should be removed. This can be done by using a wooden toothpick moistened in the water and alcohol solution mentioned above. If lacquer or varnish is present, remove it before polishing (but only if adequate facilities are available because the process requires toxic and flammable solvents). A mild polish, such as jeweller's cloth, is recommended for most mildly tarnished copper, brass and bronze pieces. The cloth contains a fine abrasive, but even so excess metal can be removed by rubbing too hard. Use a more abrasive polish, such as liquid metal polish, only if using the cloth is ineffective. Most polishes leave a blackish residue, which can be removed by softly polishing with a plain piece of flannelette. Polishing should be done only if the surface can be protected from tarnishing again. There is no point in polishing away material from the surface if tarnish is allowed to reform.
Are the rooflights prone to condensation?
Condensation is the water that results from the conversion of water vapour in the atmosphere. The air in our homes always contains water vapour, which is usually invisible. The warmer the air, the more water vapour it can hold, but there is a limit to the amount it can hold for a given temperature.

I have been told that Pilkington Activ can be easily scratched and should this happen the whole unit needs to be replaced. Is this true?
Suppliers that do not offer Pilkington Activ are often quick to dismiss the benefits of such a revolution in glass. The Pilkington Activ coating is applied as the glass is cooling down in the float process and is what is known as a Pyrolitic or hard coat. This happens at around 600 degrees C.
We have just purchased a number of your Lumen Conservation Sky Lights and would like advice on cleaning the glass.
The Lumen range of conservation rooflights are supplied with Pilkington Activ self cleaning glass as standard. A specia coating on the glass reacts with ultra-iolet rays from natural daylight to break down and disintergrate organic dirt. When rainwater hits the glass the loosened dirt is washed away. For further details about Pilkington Activ, visit www.pilkingtonselfcleaningglass.co.uk.
What do you recommend in terms of maintenance?
MAINTENANCE The Lumen range of conservation rooflights from Tuscan Foundry Products are manufactured of folded and welded steel section, and protected by a zinc coating, with a polyester powder paint finish. This combination should ensure a long and low maintenance life but is subject to the following factors: i) The location in which the product is installed ii) The condition of the coatings when the rooflight is installed iii) The frequency and quality of cleaning and maintenance The protective coatings applied are able to offer a predictable longevity according to the location of installation. To ensure that our Lumen rooflights offer the predicted longevity, they must be installed with the paint and zinc coating intact and be regularly maintained. Building products are frequently damaged on site prior to installation. Any damage to the powder coating or zinc finish will adversely affect its longevity. It is advisable that the Lumen rooflights are handled and stored with care. Keep the rooflights well protected until they are required. Prior to the installation, check thoroughly for chips and scratches to the powder coating. If there are shallow or superficial scratches or chips then these can be treated with a touch up paint available from Tuscan Foundry Products. If there are deep scratches or extensive parts of the powder coating are damaged then consult the building contractor or architect as the rooflight may need to be replaced. Maintenance at regular intervals is essential to uphold the longevity of the Lumen rooflight and to ensure the guarantee is valid. This consists for the most part of cleaning the accessible parts of the product. Cleaning should be carried out regularly and at no more than six monthly intervals. In areas exposed to extreme weather or along costal areas, this time should be reduced to every four months. As the external surfaces of the rooflight are subject to the bulk of weathering and are largely inaccessible from the inside, cleaning should be carried out from outside if possible. If this is not possible the rooflight casement should be wound open to its furthest extent and then cleaned from the inside. Wash the accessible metal parts of the rooflight with warm soapy water, a soft cloth and rinse any cleaned sections with clean warm water. Do not use any abrasive cleaners or hard bristle brushes. The winding mechanisms should be maintained at least every six months although it can be done at more regular intervals if required. To clean the mechanism use a damp cloth with warm soapy water. A non oil based product such as a silicone spray or Easy Glide can be used but this may attract dust. Do not use a mineral or synthetic oil as this will eventually damage the mechanism. Maintenance of the double glazed Pilkington Activ units must be followed in accordance with the attached Pilkington leaflet. Failure to do this will invalidate the unit warranty. If this sheet is not accompanied by the Pilkington leaflet, please call our sales office on 01409 255120 for a copy. We recommend that the following maintenance is carried out on an annual basis. Inspect the powder coat finish. Inspect all of the visible areas of metalwork for signs of cracking or chipping. If required a touch up paint is available from Tuscan Foundry Products (01409 255120). Clear away any material that has lodged in the top gutter of the rooflight. If allowed to build up, an accumulation of leaves, twigs and other items can eventually lead to leakage at the rooflight head. In addition, chemicals contained in debris can have an effect on the powder coating at the top gutter. Open the rooflight casement to its fullest degree to ensure all debris can be removed. We strongly recommend oiling the hinges on all Lumen rooflights to reduce wear at the point where the powder coating bears upon the stainless steel hinge bolts. A light engineering oil such as WD40 or 3in1 oil will suffice. Use oil sparingly and apply only to the middle part of the hinge. Should you have any queries concerning the treatment of scratches, damage or maintenance, contact our sales office on 01409 255120.
