Thin-build aerogel insulation coatings can be evaluated where conventional boards are constrained by geometry, added thickness, weight or construction access. They should be specified as a complete coating system and not as an isolated thermal layer.
Survey the existing envelope
Identify substrate type, cracks, salts, moisture sources, previous coatings and areas of thermal bridging. Adhesion and moisture problems must be corrected before the insulation coating is applied.
Define the coating build
State the primer, number of insulation coats, target dry thickness, topcoat and curing window. Application conditions should include substrate temperature, relative humidity and protection from rain or condensation.
Evaluate data in context
Review thermal conductivity, added thermal resistance, adhesion, water resistance and VOC information with the test method and sample configuration. Project performance also depends on workmanship and the existing wall or roof assembly.
