Most building code issues need to be addressed on a project-by-project basis. Since fire protection requirements can be particularly challenging to assess, we work with the best fire protection consultants to ensure appropriate use of our products in specific buildings.

In the U.S., there are very few limitations on the use of fiberglass frames in non-combustible construction. The International Code Council (ICC) has confirmed that window sashes and frames made of combustible material are permitted in Type I and II buildings (Item #5, Section 603.1 IBC).

In Canada, building codes permit the use of fiberglass frames in combustible construction. In non-combustible construction, fiberglass windows are permitted where they are separated by a 1-meter horizontal spandrel (walls or slab extensions, such as concrete balconies or eyebrows, may form part of this separation) and the window area does not exceed 40% of the exterior wall area for each fire compartment. It is possible to use fiberglass frames in non-combustible situations that exceed these limitations: appropriate design, supported by fire modeling or code consultation, often permits additional design flexibility.
