Every seam is hot-air welded into a single homogenous skin, so there's no seam tape to fail years down the line — the roof is effectively one continuous sheet of plastic from edge to edge. It's a different installation discipline to EPDM rubber (welding equipment and training rather than a roller and adhesive), which is exactly why it holds a separate, established place in UK flat roofing rather than competing head-on with our EPDM range.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFlexible PVC membrane, 1.5mm gauge, in five real fixing\/construction systems: loose-laid ballasted, mechanically fixed, elastomeric-modified mechanically fixed, fully adhesive-bonded, and fleece-backed\u003c\/li\u003e\n\u003cli\u003eHot-air welded seams form a continuous, monolithic waterproofing layer\u003c\/li\u003e\n\u003cli\u003eAnthracite Grey or Dark Grey depending on system (see specification table)\u003c\/li\u003e\n\u003cli\u003eSupplied in trade rolls — 1.05m or 2.1m widths\u003c\/li\u003e\n\u003cli\u003eSuitable for new-build and refurbishment flat roofs, typically over insulation on a warm roof build-up\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSystem\u003c\/th\u003e\n\u003cth\u003eFixing method\u003c\/th\u003e\n\u003cth\u003eColour\u003c\/th\u003e\n\u003cth\u003eRoll size\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eD — Loose-Laid\u003c\/td\u003e\n\u003ctd\u003eBallasted (requires ballast layer over membrane)\u003c\/td\u003e\n\u003ctd\u003eAnthracite Grey\u003c\/td\u003e\n\u003ctd\u003e1.05m x 20m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMF — Mechanically Fixed\u003c\/td\u003e\n\u003ctd\u003eMechanically fastened through insulation to deck\u003c\/td\u003e\n\u003ctd\u003eAnthracite Grey\u003c\/td\u003e\n\u003ctd\u003e1.05m x 20m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEMF — Mechanically Fixed\u003c\/td\u003e\n\u003ctd\u003eElastomeric-modified, mechanically fastened\u003c\/td\u003e\n\u003ctd\u003eDark Grey\u003c\/td\u003e\n\u003ctd\u003e1.05m x 20m \/ 2.1m x 20m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEBM — Adhesive Bonded\u003c\/td\u003e\n\u003ctd\u003eFully bonded with contact adhesive\u003c\/td\u003e\n\u003ctd\u003eDark Grey\u003c\/td\u003e\n\u003ctd\u003e1.05m x 20m \/ 2.1m x 20m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType A — Fleece-Backed\u003c\/td\u003e\n\u003ctd\u003eBonded or mechanically fixed via fleece backing\u003c\/td\u003e\n\u003ctd\u003eAnthracite Grey\u003c\/td\u003e\n\u003ctd\u003e1.05m x 15m \/ 2.1m x 15m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctr\u003e\n\u003cth\u003eGauge\u003c\/th\u003e\n\u003ctd\u003e1.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSeaming\u003c\/th\u003e\n\u003ctd\u003eHot-air welded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCoverage per roll\u003c\/th\u003e\n\u003ctd\u003e1.05m rolls: 21m² (20m length) \/ 15.75m² (15m length). 2.1m rolls: 42m² (20m length) \/ 31.5m² (15m length)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow is this different from your EPDM rubber membrane?\u003c\/strong\u003e Both are genuine single-ply waterproofing systems, but they join differently. EPDM sheets are jointed with adhesive tape or liquid-applied seam adhesive; PVC sheets are hot-air welded into one continuous skin. PVC also tends to be specified where a lighter colour or a fully bonded\/mechanically fixed system is wanted, while EPDM is generally the more DIY-accessible option.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I install this myself?\u003c\/strong\u003e Realistically, no — not to the standard the material is capable of. Hot-air welding PVC seams correctly needs proper welding equipment and hands-on training; a poorly welded seam is a leak waiting to happen. This is a trade\/contractor-installed product, unlike our EPDM range which is designed for competent DIY installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich fixing system should I choose?\u003c\/strong\u003e Mechanically fixed (MF\/EMF) is the most common choice for refurbishment over an existing deck and copes well with movement. Fully bonded (EBM) gives the flattest, most wind-resistant finish and suits new-build. Loose-laid ballasted (D) is used where the roof structure can carry the extra weight of a stone or paving ballast layer and mechanical fixing isn't practical. Fleece-backed (Type A) adds an extra protective layer under the membrane, useful over slightly uneven decks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need a vapour control layer underneath?\u003c\/strong\u003e Yes, on a warm roof build-up — fit a VCL below your insulation, then this membrane goes above the insulation as the top waterproofing layer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat size roll do I need?\u003c\/strong\u003e Measure your roof area and add roughly 10% for laps, upstands and waste. A 2.1m wide roll covers ground faster with fewer seams than the 1.05m width, which matters on larger roofs where fewer welded joints means less on-site labour.\u003c\/p\u003e\n\u003cp\u003eBuilding a full warm roof build-up?
