Leisure Pools manufactures each composite fibreglass swimming pool using corrosive-resistant vinyl ester resin for each layer of the swimming pool construction*. As a result, Leisure Pools is able to offer a Lifetime Structural Warranty and Lifetime Structural Osmosis Warranty, making it the best available Warranty on the market today.
VINYL ESTER RESIN VS. POLYESTER RESIN
The primary ingredient in any fibreglass pool is resin. There are two different types of resin utilised today in fibreglass pool construction: polyester resin and vinyl ester resin.
Polyester resin is the cheaper, far less durable option for fibreglass pool construction. Vinyl Ester Resin is a high performance resin that provides improved strength properties and inhibits water penetration into the laminate, a process commonly referred to as Osmosis. To save on cost, most swimming pool manufacturers use primarily polyester resin, applying, at most, one single layer of vinyl ester resin.
FULL VINYL ESTER CONSTRUCTION PREVENTS OSMOSIS
The high ester content of polyester resin creates a swimming pool that is vulnerable to osmosis. Esters in the resin of a fibreglass pool are susceptible to breaking down, allowing water to penetrate through. Bubbles of trapped water and pressure continue to grow in-between structural layers of the pool shell. If this happens, in time, this process of delamination can lead to total structural failure.
Leisure Pools understands the importance of resin quality and uses 100% FULL VINYL ESTER RESIN throughout the build process. This means water cannot penetrate through any layer of the pool shell and compromise the structural integrity of the pool shell. This is how Leisure Pools is able to offer our Lifetime Structural Osmosis Warranty.
