The handy 1.5m x 20m roll is ideal for smaller projects or detailing work where a compact, easy-to-handle roll size is preferred.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eBuilt for the Reality of a Building Site\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eMost vapour control membranes are designed to be installed once the structure is enclosed and protected. DA is different. It combines the vapour control and airtightness performance expected of an internal membrane with the physical robustness to cope with exposure to the elements, foot traffic, and the general punishment of a live construction site.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe membrane has a three-layer structure: a functional airtight film sandwiched between two durable polypropylene fleece layers. The fleece gives DA its characteristic toughness — it resists tearing, scuffing, and damage from being walked over, making it particularly well suited to floor applications and to situations where the membrane will be installed before other trades have finished working in the same area. The green-coloured outer fleece also minimises glare when working in bright conditions externally.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eThe Key Advantage: Up to 3 Months' Weather Exposure\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eOn timber frame and CLT buildings where external insulation is installed after the structural frame is up, there's often a period where the internal membrane is the only line of defence against the weather. DA is specifically designed for this situation. It can be installed directly to the timber frame or CLT at an early stage in the project, making the structure airtight and temporarily weatherproof while other work continues — handling driving rain and UV exposure for up to three months before the external insulation and permanent windtight membrane go on.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis also makes DA a useful planning tool. A strip can be fixed over a roof joist before rafters are installed, leaving accessible, easy-to-tape edges that allow the airtight layer to be continued seamlessly later in the project without having to work in awkward confined spaces.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhere DA Is Used\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eTimber frame and CLT roofs, walls, and ceilings where the membrane will be temporarily exposed externally during construction\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAbove-rafter applications on sarking boards beneath insulation, on diffusion-open roof structures\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSuspended timber floor refurbishment — DA's durability makes it the preferred choice over standard membranes where floorboards will be laid over the top\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eEarly-stage airtightness detailing at junctions and structural interfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eFix with galvanised staples (minimum 10mm wide x 8mm long) at 100mm centres in the overlap zone, reducing to 50mm if dense-pack blown insulation is being compressed against the membrane. Leave a 40mm overlap at adjacent structural elements to allow for taping later. Overlap between membrane runs should be a minimum of 100mm. The printed guide lines on the membrane help maintain consistent overlap widths and keep tape lines straight. Seal overlaps with Tescon Vana tape, pressing firmly with a seam roller. For connections to rough masonry or concrete, use Orcon F sealant. Always tape onto the green fleece face of the membrane for best adhesion.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eTechnical Specification\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRoll size: 1.5m x 20m (30m² coverage)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSurface weight: 130 ±5 g\/m²\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSd value: 2.05–2.55m (fixed, not humidity variable)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eElongation: 90% (MD and CD)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eTensile strength MD: 230 N\/5cm \/ CD: 200 N\/5cm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eNail tear resistance MD: 120N \/ CD: 115N\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMoisture vapour diffusion resistance factor: 5,000 μ\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWater resistance: W1\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eUV and weather exposure: up to 3 months\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFire rating: Class E\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCE marked to DIN EN 13984\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eIndoor air quality rating: A+\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWarranty\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e10-year warranty when installed as part of the full Proclima system. 6-year warranty when used alongside non-Proclima products.\u003c\/p\u003e","brand":"Trade Prices Online","offers":[{"title":"Default Title","offer_id":57098332078460,"sku":"PHPC030","price":77.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0381\/0535\/0275\/files\/p_DA-crop_659d5109-3db2-4a82-b53d-0d8b2e70298a.webp?v=1782373395","url":"https:\/\/tradepricesonline.co.uk\/products\/pro-clima-da-1-5m-handy-roll-1-5m-x-20m-1","provider":"Trade Prices Online","version":"1.0","type":"link"}
