Duokote Thermal Blanket

Duokote Aug 10

Product Description

How it works

  • Thermal blanket covers float on the pool surface. The closed cell foam core creates an insulating layer which traps heat in the pool.

There are two key causes of heat loss

1 – Radiated heat loss

  • Heat transfers from hot to cold. When the air temperature is lower than the pool water temperature heat will radiate out of the water into the air. This typically occurs at night and on colder days. The pool blanket acts as an insulating barrier to minimise this transfer.
  • Thermal resistance (R) is a measure of insulation effectiveness. Heat is transferred from one material (water) to another (air) by conduction, convection and/or radiation. Insulators minimise the transfer of heat energy. The R-value is an indication of how well a material insulate.

2 – Evaporation heat loss

  • The majority of the heat loss (approx 95%) is through evaporation.
  • A pool cover provides a physical barrier which virtually eliminates evaporation.
  • Preventing evaporation provides the additional benefit of reducing the need to continually top up the pool with tap water.

Applications

  • The heavy duty duokote is suitable for both commercial and residential pools.
  • The duokote’s superior heat retention make it the preferred option for heated pools.
  • Duokote’s durability make it the preferred option for schools and commercial applications.

Construction

  • A layer of closed cell foam laminated between two sheets of woven, p.e. film.
  • The p.e. film is u.v. stabilised and formulated specifically for the harsh pool environment.

Our Clients Say

"We have had a pool for over 35 years which has been looked after by various members of the family. When it became apparent that the pool was in need of painting/resurfacing, we made contact with Sparkling Pools. We were dreading the thought of the disruption, noise, dirt and having contractors on site for several weeks.

We had the pleasure of meeting Grant whose considerable knowledge of swimming pools is so impressive. He checked out not only the pool finish, advised us of the various alternatives open to us, but also the machinery and ancillary equipment. We were so impressed that we gave Sparkling Pools our contract to resurface and we enjoyed a textbook example of a perfect contract."
