Need a re-roof - Think again !

Is your home protected? Many home owners do not realise just how much of their hard earned money is disapearing through the roof. Research shows that up to 40% of heat loss is because the roof or loft space is not insulated properly. New regulations aim to combat this but they only relate to new builds and loft conversions so older homes are still suffering. Typical problems are nail fatigue, slipped and broken slates or tiles, condensation, crumbling back pointing, torn roof felt or even no roof felt at all! When a roof starts to leak is about the time most people decide to address the problem, usualy deciding to re-roof the whole property. There is an alternate. Spray Polyurethane Foam is a product that has been around in the UK for over 20 years, yet most home owners are still unaware of the advantages of this system over a re-roof. It is suitable for application to any kind of roof structure, whether flat or pitched. This process restores and extends the life of the roof. Polyurethane foam is a superior insulator than traditional methods. "U" FACTOR represents the measurement of the amount of heat which passes through a composite of materials (U heat loss). Typical foam thickness used in the encapsulation of domestic roofing materials achieves the following U values: 20mm ..... ..... ..... U Value = .98 40mm ..... ..... ..... U Value = .52 70mm ..... ..... ..... U Value = .29 The lower the U-value the greater the heat retention. At a spray foam thickness of 40mm, there would be a need to incorporate the listed materials by the given percentage increase to achieve a comparable U-value and therefore the same degree of insulation. Polystyrene ..... 64mm ..... ( 60%) Mineral Fibre ..... 72mm ..... ( 80%) Cork ..... ..... 80mm ..... (100%) Cellular Glass 88mm ..... (120%) Initially applied in a liquid form it expands to 20 times its original size and seals any unwanted air ingress. This locks the independent tiles into one solid structure, cutting heat loss by up to 80% and only adding 2Kg/m2 in weight to the roof. It ensures that the roof is more resistant to storms and gales preventing the ingress of wind driven dust, rain and snow. Spray Foam Insulation has the same breath-ability and combustibility as wood. It meets BS476 Part 1 Surface Spread of Flame. It does not present a fire risk and is also BBA approved. This Eco-friendly product is used and endorsed by local Councils, Health Authorities, commerce, industry and the domestic user throughout the UK. So, before you decide on an expensive and disruptive re-roof take a look at Polyurethane Spray Foam Insulation, you will be surprised just how cost effective and affordable it realy is.
