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!

An interstitial gap between foam beads within a spa cover.

An interstitial gap between foam beads within a spa cover.

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.

Why should I replace my spa cover with the Airframe?

Four good reasons to upgrade your EPS foam spa cover to the Airframe

1. Your open cell EPS foam spa cover is water heavy…on purpose

Open cell Expanded Polystyrene should not be used for insulating a spa outdoors. Condensation is inevitable and the average spa cover can be effective for a few months before water vapor renders it little or no insulating value. While unhealthy mold breeds in the sealed cores, water permeation continues until the cover becomes unwieldy…energy consumption doubles for the unaware spa owner.

A new EPS foam/vinyl spa cover weighs on average 45 pounds. If you have had your spa cover for a year it has probably gained water weight that greatly reduces its R value.

The average EPS spa cover contains the equivalent of 3,520 Styrofoam drinking cups. Open cell EPS foam acts like a giant sponge, gaining up to 40 pounds of water weight in just 18 months on an outdoor heated spa. Spa cover companies sell vinyl bags from 2 to 6 mils thick to wrap the foam cores in a futile effort to prevent condensation buildup…and charge more for double bagging to better retain that condensation.

 The Airframe spa cover weighs on average 38 pounds and does not gain weight.


2. Why expose your family to dangerous Volatile Organic Compounds (VOC’s) / chemicals?

Chemicals from the petroleum based vinyl and foam cores drip into your spa water.

Health issues are a concern as the Expanded Polystyrene cores and their Polyvinyl Chloride zippered bags become unstable and off gas when exposed to sanitizers. Sanitizers act to degrade the stability of those petrol-chemical compositions. Chlorine and ozone (strong oxidizers) attack the chemical compounds of PVC and styrene foam to create airborne Volatile Organic Compounds. These VOC’s are considered harmful to humans if touched or inhaled.

In contrast, the Coverplay Airframe spa cover has a gas permeable, outdoor acrylic fabric allowing the cover to breathe. The vapor barrier facing the water is a radiant shield that reflects 95% of the heat back to the water and is unaffected by sanitizers. It DOES NOT contain the harmful styrene, benzene, pentane or PVC’s that foam/vinyl covers do.  The Airframe is truly a Hypoallergenic spa cover.

 The Airframe spa cover does not emit dangerous VOC’s like EPS/vinyl spa covers. 


3. Your spas cover smells.

If you smell odors emanating from your spa it may be mold and bacteria growing inside the water logged Styrofoam or dangerous VOC’s from sanitation efforts… it is best to avoid inhaling these vapors or skin contact with any dripping, oozing residue.

Open cell foam hot tub covers begin storing water vapor from the first day of use. The speed at which an EPS cover degrades is dependent upon the difference in temperatures of the spa water and surrounding air. Spa owners delay replacing wet and heavy foam spa covers if they, “don’t look that bad” while accepting access to only half of their spa.

As EPS foam spa covers fail (2 years on average) they get tossed to spend 2000 years buried in a landfill. Recyclers avoid discarded foam covers because of micro-biological cultures they contain including mold spores.

 Given a choice savvy spa owners avoid buying another water absorbing cover to foul the air we breathe and the planet we share. The, “Green” Airframe spa cover offers them that choice with an energy saving environmentally friendly design.


4. You want a spa cover solution that makes sense for your budget, health and won’t get water heavy or add more Styrofoam to the landfills.
