Thickest Hot Tub Covers: 6"-4" Tapered with 1.0# (R23.85-R37)
Product Review (submitted on August 31, 2013):
Odering from a website is always a bit daunting, but BeyondNice made it easy.The cover fits perfectly. Our old cover was waterlogged...but we had no idea how nasty it was with mold until we took it apart. Imagine the potential health hazard ! Using the tub is fun again because we don't have to wrestle with that heavy old cover. As an added benefit, we have noticed significant energy savings as the cover is so insulative!! Love, love, love it. Our only regret? Not ordering one sooner!
