Typical Applications
The SL90HDWIL is intended for cavity wall openings where the inner leaf is wider than a standard 100mm blockwork arrangement. The existing product information lists masonry, distributed timber floor and distributed roof loads. Suitability depends on the opening span, supported loads, wall construction and bearing conditions.
Installation Guidance
The existing product information advises that masonry should be built tightly against the vertical section of the channel, with a mortar joint at the top. The channel should be well filled with cured masonry before work proceeds above. Always follow Stressline's current installation instructions and the project-specific structural specification.
