Swimming pool made from environmentally friendly composite

Alaglas Swimming Pools, an American residential and commercial swimming pools specialist, has announced that it has chosen a “green” thermoset material to produce the structural segments of its composite-based pools. In fact this “green” material is a poly(ethylene terephthalate) modified polyester laminating resin stemming partially (i.e. 28%) from biologically renewable resources and/or recycled materials i.e. the EcoTeck™ H460-EKAD-50 from the American material producer AOC. The new Alaglas composite pools are made using the same manufacturing process and equipment than previous pools made from conventional petrochemical-based polyester. The pool construction begins with a sprayed-on, moisture-resistant gel coat that is backed up with a layer of chopped glass fibres in a Hydropel H010 vinyl ester. Then EcoTek™ H460-EKAG grade is used to wet out the reinforcing glass fiber in three manufacturing steps that create an engineered structural laminate : a spray up of chopped glass fibres and resin, a lay up of resin-impregnated stitched fabric that combines biaxial woven fibreglass cloth with multidirectional strand mat, and another sprayed-up layer of chopped fibres and resin.
