Download PDF Copy of these Instructions Here
Barge B.A.L is a 0.55 metal channel flashing with a captured 350°C high-temperature rockwool fire resistance insert so that when the profiled wall sheet is compressed into it, on the end gable, under the barge cap it gives it an effective seal and meets the BA.L requirement.
First up you need to trim or set the wall sheet 10mm lower than the top of the roof sheeting. This allows the rockwool insert to compress. BAL seal can cater for variances in wall sheet length of up to 20mm and still seal.The rock wool can expand or compress as needed.
For the shed that has gable end wall sheets fixed to the trim angle on the roof battens you will need to slip the BAL seal between the wall sheet and the trim angleTek screw through the wallsheet and BAL Gable end seal to the trim angle, then fix barge capping into place.
