1. Start with clean, dry surfaces and confirm compatibility with the selected adhesive.
  1. Avoid stretching insulation around fittings; cut accurate segments so the material sits naturally.
  1. Seal longitudinal and butt joints continuously to protect the vapour-control layer.
  1. Treat hangers, supports and penetrations as part of the insulation system, not as afterthoughts.
  1. Provide a suitable weatherproof and UV-resistant finish wherever the insulation is installed outdoors.
