As Alec Purdie explains, there will be instances onsite where firestoppers cannot get to both sides of the supporting construction. We now have test evidence where you can install the QuelStop Fire Batt from one side only. This detail does require a framed and lined aperture; therefore, we have also tested a way to line the opening using the QuelStop Fire Batt. To learn more, go to our standard firestopping installation detail download page or contact us.
