The high-density closed-cell EVA foam is tested to IIC 72 (ASTM E492) and STC 73 (ASTM E90), so it knocks down both impact and airborne sound, and a pre-attached silver moisture-barrier film blocks subfloor vapour with no separate poly needed on most installs. At 3 mm it cushions the step, conceals minor subfloor defects, and adds R-3 thermal value, while a high-density build resists flattening over time. The pre-attached tape strip and overlap seal seams fast as you go. One roll covers 200 sq ft. Lay it film-side down, tape the seams, and float your floor on top — mould- and mildew-resistant, odour-controlled, and built for laminate and engineered-wood installs across Scarborough and the wider GTA.\u003c\/p\u003e","brand":"NorthLine Signature","offers":[{"title":"Default Title","offer_id":42943095013470,"sku":"UNDER3MM","price":64.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0605\/0073\/8142\/files\/Gemini_Generated_Image_fu6vl5fu6vl5fu6v.png?v=1782410678","url":"https:\/\/gdbuildingsupply.com\/products\/tegra-pro-3-mm-acoustic-underlayment-eva-foam-with-moisture-barrier-iic-72-stc-73-200-sq-ft","provider":"Good Day Building Supply Inc.","version":"1.0","type":"link"}
