The temperature of outdoor surfaces on sunny days can exceed 130°F/55°C, well above the maximum safe temperature of 115°F/46°C. It is not unknown for overheated outdoor surfaces to cause painful injury—or even to burst into flame.
A That’s Really Cool!™ system can be large enough to cool an entire playground or patio deck, or can be scaled to make a park bench comfortable. That’s Really Cool!™ can be used to warm outdoor surfaces in painfully cold climates, too.
That’s Really Cool!™ can be integrated into diverse outdoor fixtures, such as handicapped-accessible handrails, formed play structures or manufactured decking. There’s also a version of That’s Really Cool!™ which can be installed on solid surfaces.
A review of local playgrounds by the Boston Globe in 2008 concluded that several “slides are too hot to even go down”
That’s Really Cool!™ greatly increases
the usefulness of playground projects, which
can cost upwards of $100,000 per project
and have a lifetime expectancy of 10-20
years. The system requires retrofitting of
molds for components in production, or
incorporation during mold-making for new
The initial cost to retrofit an injection molding
system using this technology would be
minimal, while increasing the usability and
lifespan of the product many times over.
That’s Really Cool!™ can be integrated
into existing systems or can be standalone. Ongrid or off-grid sources such as solar and
wind power can power the That’s Really
Cool!™. A simple retrofit for a backyard
playset can be easily achieved.
This illustration represents the cooling relief when That’s Really Cool!™ is applied to pool decking.
EN 563, a safety standard promulgated by the European Association for the Co-Ordination of Consumer Representation in Standardization, has set a maximum safety temperature of 156°F/69° C for plastic surfaces which will come into contact with human skin for a minimum of 10 seconds, and 165°F/74°C for plastic surfaces which will come into contact with human skin for a minimum of 4 seconds.
“New York City started posting signs, ‘Danger hot slide!’ at many of its playgrounds in 2009”
Since human skin burns if it attains a temperature of 109°F/43°C, it is even more preferred that a sufficient flow of coolant is established through the component to maintain the surface temperature of the playing surface below this temperature. Most preferably… about 100°F/37°C.
