Solves the problem of providing effective roof ventilation with none of the excessive costs that can sometimes be incurred. Designed for simple installation into new or existing glazing bars, GlazaVent relies on water-tight beads and gaskets eliminating the risk of leaks. Equally suitable for use within a domestic conservatory or shopping mall. |
