Items to Avoid

• Do not proceed if the crawlspace/ basement is damp or water is present on the floor.
• Do not use exposed foam where fire protection of combustibles is needed. Cover foam with gypsum board where required or consider using noncombustible rigid mineral wool insulation with an airtight facer.

Items to Incorporate

• It is recommended that a radon test be completed. If radon is detected, consult with a radon protection specialist to determine the best way to protect against radon exposure. This may include completely covering the existing slab with a continuous air barrier, and provide dedicated soil gas exhaust from under the slab.
• Seal around all penetrations in the floor.
