60 minutes integrity, 60 minutes insulation 60:60
Glass options offering 60 minutes insulation are limited to very thick laminated panels with a high acoustic performance. The heavy glass panels can be fully framed or butt jointed. The frame system is steel or stainless steel with the inclusion of a fully intumescent taped perimeter to both faces and intumescent silicone/cement/taped joints between the glass panels.
Glass options are Pyroclear®, Pyrostop®, Pyroguard®, Pyranova® and Pyrobel® in specific thicknesses.
The frame and door system is generally RAL polyester powder coated steel or stainless steel such as those from RP Technik GmbH https://www.rp-technik.com/en and Forster Profile Systems https://www.forster-profile.ch/gb-en/home.html
There is a wide choice of both glass options and glazing systems available so depending on the design, the location and the specific fire rating requirements we would fine tune the shortlist to the most appropriate systems based on overall cost and appearance.
