Description
Material Use:
Elastic, rapid-setting roof insulation adhesive designed for bonding polyisocyanurate, fibrous glass, or mineral fibre insulation boards to various substrates such as steel, wood, gypsum board, concrete, or compatible roofing membranes. Also suitable for laminating insulation panels together and adhering fibreboard or Re-Cover Board panels to insulation.
System Components:
- Compatible with polyisocyanurate insulation
- Works with modified bitumen membrane air/vapour barriers, kraft vapour barriers, asphalt built-up vapour barriers, and Blueskin® Air/Vapour Barriers
- Compatible with aged asphalt and coal tar roofs
- Not compatible with foamed polystyrene insulation
Applications:
- Roof deck insulation attachment
- Laminating insulation panels together
- Re-cover applications using fibreboard or Re-Cover Board panels
- Adhering insulation to compatible vapour barriers and membranes
Application Details:
- Spot Method: Apply adhesive in 25 mm (1") spots on 225 mm (9") centers; spots compress to 40–50 mm (1½"–2") diameter under pressure.
- Bead Method: Apply 20 mm (¾") wide beads on 300 mm (12") centers; place panels into wet adhesive and apply pressure.
- Install insulation panels into wet adhesive as soon as possible.
- Condition adhesive at room temperature before application in cold weather.
