{"product_id":"bradford-polyair-performa","title":"Bradford Polyair Performa","description":"\u003cp\u003eBradford Polyair Performa is a foil faced closed cell foam roll, 4 mm or 8 mm thick, in an extra heavy duty commercial grade. It works by reflection rather than by thickness, which makes it a different tool from a glasswool blanket rather than a cheaper version of one.\u003c\/p\u003e\n\u003ch3\u003eHow reflective insulation actually works\u003c\/h3\u003e\n\u003cp\u003eBradford quotes it as reflecting up to 95% of radiant heat. The catch is the air gap. A reflective face pressed hard against another surface reflects almost nothing, because the heat simply conducts across the contact. It needs a small air gap in front of the foil to do its job, so how it is installed decides how much you get out of it. \u003ca href=\"\/blogs\/blog\/blanket-vs-sarking-vs-batts\"\u003eBlanket, sarking or batts\u003c\/a\u003e sets out where each type belongs and why a foil product on its own rarely satisfies a bulk R-value requirement.\u003c\/p\u003e\n\u003ch3\u003eWeather barrier\u003c\/h3\u003e\n\u003cp\u003eTaped and sealed, it also helps block rain, dust and draughts during construction. The extra heavy duty grade is there so it survives frequent handling and knocks on a commercial site.\u003c\/p\u003e\n\u003ch3\u003eSizes\u003c\/h3\u003e\n\u003cp\u003eFive rolls, all 1350 mm wide. In 4 mm there is a 22.25 m roll covering 30.03 m², a version of the same roll with a 150 mm lap, and a 40 m roll covering 54 m². In 8 mm there is a 22.25 m roll covering 30 m² and a 30 m roll covering 40.5 m². If you are lapping and taping, allow for the overlap when you work out roll count. \u003ca href=\"\/blogs\/blog\/how-much-insulation-do-i-need\"\u003eHow much insulation do I need\u003c\/a\u003e covers the estimating.\u003c\/p\u003e\n\u003cp\u003eFor a garage or shed rather than a commercial build, look at \u003ca href=\"\/products\/bradford-polyair-unicell\"\u003ePolyair Unicell\u003c\/a\u003e.
