CodeMark certified for NCC compliance.\u003c\/p\u003e\n\u003ch3\u003eEnclosing the sub-floor changes everything\u003c\/h3\u003e\n\u003cp\u003eThe system figures tell the story clearly. In an unenclosed sub-floor Kingspan quotes RT 0.8 for heat flowing in and RT 1.6 flowing out. Enclose the sub-floor and the same product gives RT 1.6 in and RT 3.0 out. Nearly double, from the same roll. If the sub-floor can be enclosed, that decision is worth more than any change of product.\u003c\/p\u003e\n\u003ch3\u003eTwo roll formats\u003c\/h3\u003e\n\u003cp\u003ePermifloor at 1350 mm x 33.33 m covering 45 m², and Permifloor 500 supplied as two 500 mm x 30 m rolls covering 30 m². The narrow rolls suit working single-handed between joists in a confined sub-floor, which is where most of this work happens.\u003c\/p\u003e\n\u003ch3\u003ePoints to check\u003c\/h3\u003e\n\u003cp\u003eIt is Class 3 vapour permeable but it is not a water barrier, so it is not the product to rely on for that. Maximum span is 2.4 m without support mesh. It is electrically conductive, so keep it clear of wiring. Fibre-free, non-allergenic and non-irritant, and rodent and insect resistant.\u003c\/p\u003e\n\u003cp\u003eFull figures are in the table below.\u003c\/p\u003e","brand":"Kingspan","offers":[{"title":"2 x 500 mm x 30 m (30 m2)","offer_id":45225012363446,"sku":"SQ6974821","price":430.68,"currency_code":"AUD","in_stock":true},{"title":"1350 mm x 33.33 m (45 m2)","offer_id":45225012330678,"sku":"SQ4896908","price":646.09,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/3995\/3590\/files\/AIR-CELL-Permifloor-4.webp?v=1782756339","url":"https:\/\/awbm.com.au\/products\/air-cell-permifloor","provider":"AWBM","version":"1.0","type":"link"}
