The supporting structure must already be in place for the product. The dimensioning of the product will have taken into
consideration the dimensions of the supporting structure including all weathering. More information about supporting
structure construction can be found in Glazing V
ision’s sales drawings.
Please note that a minimum distance of 140mm
from the structural opening to any surrounding structured must be felt on all sides. Sufficient room for installation
(including weathering) and maintenance must also be allowed for.

It is important to consider the type of tile or other roof finish to be used. The opening in the roof should ideally be positioned
so that you get a full tile at the top and at the bottom of the product, avoiding the need to cut tiles down.
5.
It is important to ensure that the area of installation is suitably prepared. The area surrounding the supporting structure
should be clear to provide safe access during the installation works. It will be necessary to work on the outside and
therefore suitable provisions should be made for safe handling of the product, including all relevant personal protective
equipment (PPE) and safety systems for working at heights.
6.
Before starting installation, Glazing Vision advises that the physical supporting structure dimensions are cross-checked
with those given for the order, to ensure the product will fit. The supporting structure will need to be within ± 10 mm of the
ordered size (measured across the flats). The top surface of the supporting structure should be flat without undulations
greater than ± 2 mm. Also check the diagonals to ensure that the supporting structure has been constructed square. The
supporting structure must be weathered as per the sales drawings. If using any metallic waterproofing material, take care
when applying it to the product/supporting structure, as if done incorrectly it can cause a thermal bridge which can lead
to internal condensation and invalidate the product warranty.
7.
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 structure. Nothing in this manual or on Glazing
Vision’s sales drawings
constitutes a structural proposal.
8.
Preparation of the roof prior to installation will vary depending on roof type and roofing materials. A few common scenarios
are included in this manual. Please follow the applicable steps for your configuration. Glazing Vision strongly recommends
that
a ‘dry run’ (without any silicone
or butyl) is completed before committing to the final installation.
Sales Drawings
Sales drawings for the Pitchglaze can be
obtained by downloading them from Glazing Vision’s website
(www.glazingvision.co.uk/resources) or by contacting Glazing Vision.
Sales drawings should accompany this installation manual. If you do not have them then do not continue the
installation without them.
