1. Glass Layer Thickness for Wind Load Resistance → Did you know that thicker glass doesn't necessarily have to be on the exterior? Contrary to popular belief, just because the wind is coming from the outside doesn't mean the thicker glass in the sealed unit has to be positioned on the exterior. Considering that thick glass with low-E insulation is very expensive, if the low-E is on the exterior, the thick glass can be positioned on the interior. 2. Position of Setting blocks and/or Reinforcement in Horizontal Mullions When the glazing is heavy, the horizontal mullion deforms. This deformation should generally be limited to L/360 or a maximum of 3 mm. To meet this requirement, the setting blocks can be moved closer to the corners of the glazing, but never closer than 150 mm. It is also possible to add a steel reinforcement to the horizontal mullion. 3. Glass Tint → If a 10mm glass layer and a 6mm glass layer are required on one or more large sealed units of a curtain wall, ...

We were recently at the AVFQ congress in St-Hyacinthe and it was a very interesting activity. We're very happy we could also go to the "get together" the evening before it started, meeting so many people in our industry always feels great. Thanks to the AVFQ for organizing this event!  Plus, our Glaspex logo is front and center in the photo 🧐  Can't wait for the golf tournament to meet you all again!

   Windows used as guardrails: a subtlety worth knowing In relation to guardrail conditions or walls acting as guards, what is an infill panel? → Answer When a horizontal mullion (transom) or handrail is located at guardrail height or below, the glazing beneath that mullion will act as an infill panel. Infill panels are subject to concentrated load requirements equal to half of the guardrail load, in addition to wind load. What this means in practice The interior glass lite of the insulated glass unit will generally need to be tempered. For balustrades, the glazing must be tempered or laminated; refer to CSA A500, Table 6.1.
