FLAT ROOFING Protan says its new flat roofing system is giving contractors peace of mind that however windy, the roof will stay in place due to its vacuum system. According to the company, the flat roofing system is the only single ply roofing method to harness natural air movement to provide adhesion. It uses strategically positioned vacuum vents across the roof, with fixings present only at the perimeter and penetrations. Air movement across the roof and through the vents creates suction, drawing air from between the membrane and airtight substrate below, causing the single ply to ‘stick’ to the roof. The stronger the wind, the more the membrane adheres to the roof structure. Fraser Maitland, Protan UK managing director, said: “It seems increasingly that the country is being hit by unusually high winds, causing £billions of damage as roofs are ripped off. Protan vacuum system gives a guaranteed solution to ensuring the roof stays in place, however gusty the weather. Protan vacuum system works by loose-laying Protan SE membrane Zink Copper Stainless over an airtight, load-bearing vapour control layer, which itself is on top of a metal or concrete sealed deck. The process, combined with the reduced number of fixings, delivers fast installation and reduced labour time. As the construction process avoids penetration of the support structure and vapour control layer, and requires an airtight base, the system can help achieve, or exceed, the requirements of Building Regulations Approved Document L. Mr. Maitland added: “Protan is one of the top three membrane manufacturers in Europe, and developed the vacuum system to provide an effective, value solution to single ply roofing in the continent, especially Scandinavia, where winds equivalent to a category four hurricane have been experienced in the past few years.” www.protan.co.uk Withstanding uplift 01992 801927 www.almhm.co.uk ROOF SCREED DEWAT E R I N G Entrapped water in Roof / Floor Screeds and Insulations whether caused by a failed roof, defective installation or flooding requires the Caretec Dewatering System.
