Spa Covers Exposed!

Legitimate reasons to re-consider EPS foam spa cover replacement

  1. Most spa covers fail to insulate effectively due to water saturation in one year or less
  2. IARC classifies styrene a probable carcinogen in humans.
  3. Toxic VOC’s released when exposed to Chlorine, Bromine, Ozone or Hydrogen Peroxide
  4. Spa bathers are exposed to neuro-toxins benzene/styrene, PVC from off gassing.
  5. Millions of energy dollars lost every month to water soaked styrene spa covers.
  6. Mountains of styrene spa covers, tossed in American landfills monthly.
  7. Traditional foam spa covers contain a Highly Toxic Carcinogenic HBCD.  Read EPA’s report

Foam does not insulate… AIR in the foam insulates!

The average effective insulating value of polystyrene foam/vinyl spa covers is less than one year due to interstitial gaps between foam beads allowing condensation to saturate, naturally. Hot tub cover retailer’s sell vapor barriers that actually help hold that water until cover weight is unmanageable.

Warm water expands air in polystyrene foam until cooler ambient weather condenses it creating water vapor inside the core. Increased differences in heated water temperature and cooler outdoor weather conditions accelerate water permeation accordingly. Water saturated foam covers conduct heat and could cost up to 3 times more to heat a spa on standby ready power. Compounding that problem, this wasteful use of styrene foam renders it non-recyclable as wet foam can harbor microorganisms and mold spores. Other HCFC closed cell foams are expensive and 1000+ times more damaging to our planet than CO2.

 

IARC (International Agency for Research on Cancer) classifies styrene a probable carcinogen in humans. The Environmental Protection Agency (EPA) classifies styrene a, “Class A” probable carcinogen yetis reluctant to set guidelines for styrene use prompting citizens to unite against EPS foam and ban it from food and beverage containers in communities all over the world. San Francisco has passed the ordinance against EPS unanimously… law as of 1/1/17.

 

Toxic VOC’s released when polystyrene and PVC are exposed to strong oxidizers! Material Safety Data Sheet (MSDS) information warns EPS foam and PVC vinyl become unstable when exposed tostrong oxidizers and a health risk releasing dangerous and harmful VOC’s. Strong oxidizers include water sanitizer’s chlorine, bromine, ozone and hydrogen peroxide. (Sitting in a spa, foam cover halfopen, places bathers within inches of off-gassing VOC’s and full exposure).

 

Spa bathers with polystyrene covers are likely to be exposed continually to neuro toxins benzene, styrene and PVC toxic vapors if their heated water has sanitizers. Most spa users have grown accustomed to the smell of accumulating toxic fumes that escape when opening their spa and are unaware the faded vinyl on the underside is a dire warning. These are signs of oxidizers attacking the chemicals that make up PVC vinyl and polystyrene foam. These vaporized chemicals are neuro-toxins that can affect memory, sense of smell, taste and hearing. They are associated with Dementia, lethargy and color blindness and can be blamed for breathing disorders including asthma. The spa industry seems content to await legislation before pursuing a user safe alternative.

 

Many people are told spas use about $15 in energy a month, the truth is with a dual hinged foam cover that number is closer to $50 to $90 on average in CA. Wet foam covers cost spa owners even more to operate on standby ready power! California spa owners squander about $23M a month in wasteful energy on spas with wet foam spa covers.

 

Disposal of heavy, wet polystyrene spa covers after 2 or 3 years of service would suggest an inappropriate use to the most casual observer. A worse decision is to leave it on the spa for another2 or 3 years wasting energy while leaking toxic VOC’s. The path of polystyrene foam reminds one of asbestos in the 50’s where industry just couldn’t find enough places to misuse it. Research discloses the insidious nature of polystyrene foam for use as a spa cover yet the spa industry continues to expose our health, our planet, our wildlife and water supply to a grim future.
