Overview

This waterborne aerogel insulation coating is intended for thin-build building-envelope and retrofit evaluations where board insulation is difficult to install.

The published evidence is for the identified test sample and system context. Surface preparation, primer, dry-film build and finish layer must be defined for each project.

Handling / storage

  • Confirm a clean, dry, stable substrate and compatible primer before trial application.
  • Build the insulation layer and protective finish to the approved system sequence and allow each layer to dry as specified.

Selection limits

  • Not a substitute for a whole-building energy model, facade design or local code review.
  • Thermal and adhesion results do not establish weathering, crack bridging or moisture performance for an untested substrate.

Product FAQ

Is 0.040 W/(m·K) a project guarantee?

No. It is a reported value for the submitted sample under the report conditions; verify the full system for the intended project.

Can this replace conventional facade insulation everywhere?

Selection depends on target thermal performance, permitted thickness, substrate, climate exposure and local building requirements.
