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.
- Primer
- Confirm a compatible primer for the prepared substrate.
- Aerogel insulation layer
- Define the build and drying intervals for the selected coating.
- Protective finish
- Select the finish for the intended exposure and curing conditions.
Typical applications: Exterior walls, Roof retrofit, Factory buildings, Energy-saving renovation.

Handling and selection limits
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.
