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.
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.
Information to collect
- Building area
- Existing substrate
- Climate exposure
- Target thermal performance
- Moisture or waterproofing concerns
Applicable technical data
| Property | Reported value | Basis |
|---|---|---|
| Thermal conductivity | 0.040 W/(m·K) | Report XT226-250016; submitted sample under listed methods. |
| Added thermal resistance | 0.26 m²·K/W | Report XT226-250016; submitted sample and report conditions. |
| VOC content | 35 g/L | Report XT226-250016; submitted sample. |
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.
System limits
- A coating result is not a whole-building thermal calculation.
- Facade, vapor and weather-exposure design must meet local requirements.

Application FAQ
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.
