Air Vents Goretex
Some EPS Foams (especially block foam or lightweight molded blanks) contain very small air pockets between the foam beads which expand and contract with changing temperatures. If a board is dinged while surfing and water gets in, additional heat (leaving your board on the beach or in a hot car) will cause the water to change phase in to steam and exert pressure on the fibreglass skin - pushing the glass away from the foam (de-lamination).
Our Air Vent provides full time Gortex venting of your EPS and hollow wood boards without an extra part to install in your deck. The Air Vent's poly mesh screen size allows air (steam) out of the board to relieve internal pressure but will not allow water molecules in and is waterproof up to 2m.
