Although pink is arguably one of the best colors, it’s not the best to have exposed pink foam board insulation in your attic or crawlspace areas for safety reasons.  I recommend that you cover exposed pink foam board in your attic/crawlspace with a noncombustible material, or remove it if that’s impractical. 

Exposed pink foam board insulation is combustible and could catch fire and creep up on unwary dwellers.  Either take that stuff out, or get it covered!

Having pink foam board insulation in your attic or crawlspace does not mean that your home will undoubtably at some point catch fire.  But because the possibility remains, I recommend you remove or cover pink foam board insulation.
