Best Practices for Installing a Crawl Space Vapor Barrier

[christinescoms]

Hello everyone,

I’m in the process of installing a vapor barrier in my crawl space and have a few questions. Should I opt for a thicker barrier or is a thinner one sufficient?

I’m also wondering if I need to seal the seams with tape or adhesive, and whether I should cover the entire ground area or just specific sections.

Additionally, is it necessary to extend the barrier up the walls, and if so, by how much?

Any tips on installation to ensure effectiveness would be greatly appreciated.

That's down to your local building regulations / codes. Also check if you need gastight or semipermeable.
