These products can be very heavy. Glazing Vision strongly recommends that a structural engineer is consulted when
designing the structure(s) that will support the product and the surrounding roof. Nothing in this manual constitutes a
structural proposal.
Before continuing onto the installation instructions:
The rafters and horizontal trimmers that will support the product should be complete and in place.
