Earthbag projects that take more than a few weeks to build will need to be protected from the sun. You could cover walls with tarps or coat the bags or tubes with latex paint. Or you could order UV-rated bags or tubes that are specially coated to protect against sunlight. The higher the UV rating, the longer these products will last in direct sunlight.

Here’s one company offering bags with a 1,600 UV (ultra violet) rating — Commercial Bag and Supply Company. I found one company with a 2,000 UV rating, although they don’t carry standard 18”x30” bags. Pranavi Polymers Pvt. Ltd. makes UV-rated bags to order. Use Google to find companies who sell standard sized UV-rated bags near you. Bags like this can save a lot of work and protect your structure from UV degradation.

UV-rated Bags — 2 Comments

  1. Hello Owen,
    We also sell UV protected woven poly bags and we always have thousands of 18×30’s in stock. I really would like to get more exposure for Pacific Packaging on your blog, if that is possible. I don’t know if you are open to paid advertising but I would be willing to consider that in the future as well.

    Mike
