Generic Glass-In Vent Plug

The Generic Glass-In Vent Plug is an economical vent designed for EPS foam and hollow-core composite boards, including foil boards, paddle boards (SUPs), and EPS surfboards.

Vent plugs allow EPS and hollow-core boards to "breathe" as internal air expands with heat, helping equalize internal pressure. This glass-in vent is designed to be installed during board construction prior to lamination and glassed over for a clean, flush finish.

The Generic Glass-In Vent is an excellent choice for new board builds where a simple, cost-effective vent is preferred.
