DIY mechanics, custom fabricators, and homeowners who need a flexible, high-temperature reflective barrier will find FLASLD Thermal Block useful. It’s designed for people who want a durable, adhesive-backed solution to reduce radiant heat exposure to nearby components and surfaces without specialized tools or installers. If you require a thicker structural barrier or a product rated for direct flame contact, consult technical specifications or a heat-protection specialist — this product is optimized for radiant heat reflection and insulation in automotive and household applications.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can FLASLD Thermal Block be used directly on hot exhaust pipes?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No—it's designed for radiant heat reflection and protection of nearby parts, not for continuous direct flame or direct contact with extremely hot exhaust pipes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will the adhesive survive an engine bay environment?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, the factory-applied adhesive is formulated for automotive temperatures and vibration when applied to clean, dry surfaces.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"FLASLD","offers":[{"title":"Default Title","offer_id":48081136189598,"sku":"B0D174GCQN","price":79.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/flasld-thermal-block-front-view.jpg?v=1785797245","url":"https:\/\/northtrailauto.ca\/products\/flasld-thermal-block-automotive-heat-shield-40-x-80-aluminized-adhesive-backed-reflective-barrier","provider":"North Trail Auto","version":"1.0","type":"link"}
