To determine a suitable glass specification for resisting wind and snow loads, the following information is required:

• Size of glass pane and glazing angle if the glass is not within 15 degrees of vertical
• Method of fixing e.g. fully framed, two edge supported
• Single, double or triple glazing and any glass type preferences e.g. toughened, laminated etc.
• Design wind load and snow load for the location (For sloping glazing this can be the upward and downward loads separately if they are not the same. Pilkington do not have sufficient information about your building to calculate these loads due to the wide range of factors that influence the design load.)
• Mention any other factors that may influence the glass choice such as colours or coatings for solar control or thermal insulation

The above will form the input parameters for undertaking wind and snow load calculations using the Pilkington Mechanical Strength online calculator available via MyPilkington.  To register for MyPilkington, please click here.
