Full Vinyl Ester Resin Construction Overview

Leisure Pools manufactures each composite fiberglass swimming pool using Corrosive Resistant Vinyl Ester Resin for each layer of the swimming pool construction*. As a result of using Corrosive Resistant Vinyl Ester Resin for each layer of the swimming pool, 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.

By way of background, standard fiberglass pools are made up of a number of layers being:

1. Gelcoat Color Layer
2. Corrosive Resistant Vinyl Ester Resin with Fiberglass Layer
3. Structural Polyester Resin with Fiberglass Layer
4. Polyester Resin Finishing Layer

One of the key layers that has been introduced into fiberglass construction over the last 20 years has been the use of a Corrosive Resistant Vinyl Ester Layer. 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.

Standard Pool Failures with Polyester Resin
Standard fiberglass pool manufacturers only use Vinyl Ester Resin in one layer of the swimming pool as Vinyl Ester Resin is generally double the cost of a Polyester Resin, which is a cheaper resin used to provide bulk to the swimming pool. Unfortunately, even with this one layer of Vinyl Ester Resin, Osmosis has still on occasion appeared and swimming pools have failed using this standard manufacturing method. This may be because manufacturers have attempted to use as little Vinyl Ester Resin as possible.

A swimming pool is a large investment, so in order to eliminate the risk of failure, Leisure Pools does not take any short cuts and has a patent pending that will sanction Leisure Pools as the only company able to offer a composite fiberglass swimming pool with a full Vinyl Ester Resin Construction.

*Except the gelcoat color layer.

Full Vinyl Ester Resin Construction Benefits

Leisure Pools construct their pools using full Vinyl Ester Resin in order to offer our customers the following amazing benefits:

  • Vinyl Ester Resin provides improved structural strength properties over traditional Polyester Resin therefore enabling Leisure Pools to offer a stronger swimming pool and a Lifetime Structural Warranty.
  • By constructing all layers after the Gelcoat Color with Vinyl Ester Resin Leisure Pools is able to offer a Lifetime Structural Osmosis Warranty.
  • Testing shows that a Leisure Pools Composite Armour™ Full Vinyl Ester Resin swimming pool is 111% stronger than a standard fiberglass swimming pool.

A swimming pool is something that should last a long time. Customers spend tens of thousand of dollars on a swimming pool project and as a result the swimming pool shell must last. Leisure Pools’ Patent Pending Full Vinyl Ester Resin swimming pool is another key to step to ensuring a stronger, longer lasting pool.

Vinyl Ester Resin v Polyester Resin
Leisure Pools has a patent pending to be the only composite fiberglass swimming pool manufacturer to use Vinyl Ester Resin for each layer after the gelcoat color layer.

Standard fiberglass swimming pool manufacturers may use one layer of Vinyl Ester Resin and then multiple layers of cheaper Polyester Resin in order to reduce overall build costs.

So what are the differences between Vinyl Ester Resin compared to a Polyester Resin:

Vinyl Ester ResinPolyester Resin
High quality expensive resinCheapest resin available
High corrosion resistancePoor corrosion resistance
High strength propertiesPoor strength properties
High resistance to micro fracturingPoor resistance to micro fracturing
High resistance to shrinkagePoor resistance to shrinkage

There are numerous technical websites that will go into detail regarding the respective resin and given the investment
of a swimming pool it is worth spending 5-10 minutes to do your own research.
