Question:
Is this suitable for a 150mm cavity? Or do you have any recommendations?
Answer:
Yes, the Manthorpe GW281-25 Lintel Tray is suitable for cavity widths from 50mm up to 150mm, so it can be used in a 150mm cavity wall construction. The GW281 has a 100mm bed size and 400mm roll width. Manthorpe's lintel tray range is specifically designed to suit cavities up to 150mm wide and can be folded to suit various lintel profiles. If your lintel has a particularly deep profile, Manthorpe also offers the GW282 with a 463mm roll width and the GW283 with a 530mm roll width for larger lintel heights and configurations. For a standard masonry cavity wall with a 150mm cavity, the GW281 is generally suitable. However, if you are using a deep cavity lintel, a wide insulated cavity with a complex lintel profile, or you need a greater upstand height, then the GW282 or GW283 may provide a better fit. If you can provide the lintel model (Catnic, IG, Keystone, Birtley, etc.), I can advise which of the GW281/282/283 options would be the best match.
