Sized for fabrication and trimming, the 40\" x 80\" panel provides a large, continuous surface that can be cut to fit hoods, firewall areas, exhaust tunnels, or household appliances where radiant heat is a concern. The aluminized surface helps deflect heat while the composite construction resists abrasion and mechanical wear.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the FLASLD Thermal Block handle extreme temperatures?\u003c\/h3\u003e\n\u003cp\u003eThe sheet is engineered with an aluminized layer over a woven silica substrate to tolerate intense heat exposure without breaking down. It can survive short bursts of very high temperatures while keeping the reverse side much cooler than unprotected surfaces.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminized finish reflects radiant heat up to approximately 95%.\u003c\/li\u003e\n  \u003cli\u003eWoven silica core resists scorched or brittle failure under high heat.\u003c\/li\u003e\n  \u003cli\u003eRated for exposure to very high temperatures in automotive environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I cut and apply this heat shield myself?\u003c\/h3\u003e\n\u003cp\u003eYes—FLASLD Thermal Block is sold as a large sheet you can trim with common tools to the shape you need.
