SOMMER High Security Louvre O·S·G Barrier


The SOMMER physical protection louvre O·S·G Barrier is designed to protect ventilation openings against external hazards while allowing air to pass through. This type of physical protection louvre consists mainly of specially shaped lamellae enclosed by a frame. The entire louvre is welded into a mounting frame, which is firmly embedded in concrete in the wall. Small louvres are manufactured in one piece. Depending on static requirements or logistical considerations, large louvres are delivered in parts and welded together on the construction site.
