Con­trol­ling mois­ture around bins 

Con­trol­ling mois­ture around bins can be a mon­u­men­tal task in any envi­ron­ment. Add the fact that Belize gets 60 inches of rain annu­ally and mois­ture becomes a huge issue. For this Beliz­ian bin site, the answer was spray foam insulation.

How can insu­la­tion con­trol moisture?

Closed-cell spray foam insu­la­tion is unique in that it has the abil­ity to expand and fill every crack and crevice. At one inch thick, it cre­ates a mois­ture bar­rier that pre­vents water from seep­ing into the bin.

Proper Water Drainage

Spray foam insu­la­tion is installed with water drainage in mind. Philip Bulfer, owner and spray foam tech­ni­cian, real­izes the impor­tance of a qual­ity instal­la­tion. “Installing the spray foam insu­la­tion to cre­ate water drainage is very impor­tant,” said Bulfer. “It takes a lit­tle bit of extra time, but proper water drainage doesn’t hap­pen with­out it.”

    That is awe­some that adding spray foam insu­la­tion can help con­trol mois­ture. I would agree that mois­ture in your home is some­thing that you would def­i­nitely want to avoid. I will remem­ber to use this arti­cle to help me bet­ter under­stand how to prop­erly insu­late my home. Thank you for sharing!
