I need to lintel over a 1200mm wide window (cavity wall), with roof rafter ends supported only
1 or 2 brick courses above this, and standard catnic-style lintels are 3 brick courses high I understand. Can you get such lintels with less rise in the box section ? Or will I need to use something different, like a separate RSJ lintel in each leaf ?Also, since there's not many brick courses over the lintel to the rafters, would a box lintel be able to cope with slight point loads that may result ?
Thanks, Simon.
