Lonsdale PlasGard Glazing Bars

PlasGard Glazing Bars


PlasGard is a simple two part glazing bar with continuous screw on cap. Approved by all the major polycarbonate sheeting manufacturers for use with multi-wall and solid plastics, PlasGard is also suitable for single glazing with glass from 6mm to 25mm. Ideal for unheated spaces such as canopies, verandahs, car ports, shelters or rail platforms. Easy to install, PlasGard offers excellent value and a wider than normal glazing rebate for exposed locations or areas where bomb-blast mitigation is required.

"In my opinion PlasGard is one of the best & also one of the simplest glazing bars on the market. Our customers love it !" – Mr Rod Sens, Omega Building Products Ltd.
