Frequently asked questions
What is the difference between "integrity only" and "integrity and insulation"?
"Integrity only" applications prevent the passage of fire through an assembly for a given time. By contrast, "integrity and insulation" applications stop the spread of fire and the radiant heat. This helps protect escape routes and building boundaries from the spread of fire.
Integrity only glass can stop the spread of fire for 30 or 60 minutes, while integrity and insulation glass can stop the spread of fire and heat from 30, 60, 90 or 120 minutes.
Do you provide aluminium fire-rated curtain walls?
All our curtain walls, including our fire-rated SR series, are made from steel rather than aluminium. This is because of steel's superior durability.
How is the SR series fire-rated curtain wall installed?
The SR series fire-rated curtain wall is installed in stick format. This means it's thermally broken, gasket glazed, self-draining and pressure equalised.
What is the maximum glazing capacity of the fire-rated SR series?
The maximum glazing capacity of the fire-rated SR series curtain wall is 90mm.
What framing depths can the fire-rated SR series have?
The fire-rated SR series curtain wall can have a framing depth of 40, 60, 90, 140 or 180mm.
What width profile does the fire-rated SR series have?
Our fire stopping curtain wall has a width profile of 60mm.
What is the thickness range of the profile wall in a fire-rated SR series curtain wall system?
The profile wall in a fire-rated SR series curtain wall system has a thickness range of 2 to 5mm.
