E Glass with Plain Weave

4 oz. E fiberglass cloth is the most common cloth used to glass a surfboard. E-glass is easy to wet our with polyester or epoxy resin and laps around the rails easily. If you want the lightest weight surfboard the common layup is 2 layers 4 oz. E cloth on the deck and 1 layer 4 oz. E-glass on the bottom. Surfboards made with all 4 oz. fiberglass cloth are light but not the strongest...

FYI the "E" in E-glass stands for "Electrical Grade" fiberglass as it was initially developed for electrical wire insulation but later was found to exhibit good reinforcement strength when coupled with a plastic resin.

The other main type of fiberglass used in surfboards is S-glass (or S-2 glass) and was developed for military and ballistic applications. S-glass has a much higher tensile strength and modulus than E-glass and is approximately 10% stiffer and 30% stronger.
