WALLTITE®
Spray Foam Insulation

External roof insulation

ELASTOSPRAY can be applied to the external surfaces of corrugated and profiled roof cladding. The in-situ application overcomes problem areas such as cracked roofing sheets and glazing, perished fixing bolt seals and gaps in the sheeting.

This practical way of insulating and weatherproofing a commercial building roof, provides a lightweight solution to condensation problems without disruption to production within the premises.

In these situations the ELASTOSPRAY needs to be provided with UV protection via a recommended membrane coating.

  • Simple, seamless insulation of critical areas
  • Suitable for virtually all substrate
  • Economic due to ‘fast track’ installation
  • Lightweight
  • Adapts to any profile without gaps
  • High compressive strength for occasional foot traffic
