Reflectivity is compromised at tear, but you can tape it and use for ground insulation. Whole blanket reflectivity is gone, so body-wrap use fails.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How much warmer do I get with this vs. without?\u003c\/strong\u003e In calm conditions, 5–10°F effective warmth gain (depends on existing insulation). In wind, the effect is negated unless wrapped tight (traps little air).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this safe against fire?\u003c\/strong\u003e Aluminized plastic will melt and stick if exposed to direct flame. Not near fire.
