Reliabilt glass block hopper-style vents are made to work with virtually all 3 in. thick individual glass blocks allowing access to fresh air without compromising security. Reliabilt 16 in. x 8 in. vents are used in place of two 8 in. x 8 in. x 3 in. glass blocks when assembling and installing a glass block window made from individual 3 in. glass blocks. Double pane, privacy glass combined with full weather stripping surrounding the perimeter of the sash enhances the thermal efficiency. Reliabilt glass block hopper-style vents can be used in either a mortar or silicone glass block assembly. The included removable screen makes cleaning and replacement simple and easy. Our 100% vinyl frame ensures a maintenance-free experience with nothing to peel or rust and is the perfect choice for use in glass block basement, utility, garage and many other window applications.
