JB WINDOW window assemblies are perfect for installation in fixed walls (e.g., plasterboard, masonry, ...).  These window assemblies come in different variants, and just like the JB DOOR door assemblies, we have metal, plywood and solid wood frames. 

For coupling different glass plates there is the choice between a vertical style or glass against glass.  This also applies to our fire-resistant designs.

JB WINDOW window assemblies are dry fit-out systems with a limited number of parts, enabling quick installation with no mess and without use of specialist tools or equipment.


Window assemblies with frames made of powder coated steel, stainless steel, and solid wood.  Available in several sections and finishes according to type and technical requirements.

Fire resistance

In tests carried out according to the European standards EN 1363-1, EN 1364-1 and EN 1634-1 some variants of the JB WINDOW range can meet the fire performance level of 30 minutes - EI30 and/or 60 minutes - EI60.
