Project Challenge
Retrofit work often has limited available thickness, uncertain existing substrates and a need to coordinate thermal and moisture performance without disrupting the envelope.
Application Guide
Aerogel Insulation Solutions for Building Energy Retrofit
Aerogel-based coatings and insulation materials can be evaluated for walls, roofs, thermal bridges and space-limited retrofit areas. Product selection depends on the existing substrate, climate conditions, moisture exposure, target thermal performance and local building requirements.

Suitable Products
System Limits
- A coating result is not a whole-building thermal calculation.
- Facade, vapor and weather-exposure design must meet local requirements.
Verification Steps
- Survey the substrate, moisture condition, thermal bridges and permitted thickness.
- Prepare a representative trial area with the selected primer, coating build and finish.
- Review the applicable TDS, test method and local requirements before specification.
Documentation and project review
Request the technical document set for the selected product grade, then verify it against the substrate, test method, system build and operating conditions.

Can a thin coating solve every retrofit requirement?
No. It must be evaluated against the target U-value, wall build-up, climate and applicable construction requirements.
