Impermax A solar-reflective aliphatic roof
An Impermax A solar-reflective roof is a named aliphatic 1K. It is not a water-based Aqua cool roof.
Write an Impermax A solar-reflective roof when the aliphatic is the membrane, not a separate topcoat. Impermax A (aliphatic moisture-activated polyurethane) cures without foam or CO2 bubbles and forms a continuous, pedestrian, crack-bridging film. Catalogue 2026 supplies it only in reflective white and grey (similar to RAL 7001). High solar reflectance, a cold roof with SRI greater than 100, can be achieved with the white.
What an Impermax A solar-reflective roof actually is
It is designed as a second layer on a cured first layer of an aromatic single-component polyurethane from the Impermax range, avoiding a final aliphatic topcoat. Applications include roofs, terraces, balconies, stadium stands, canals and outdoor neutral-water containment. It is not Impermax Aqua (water-based hybrid aliphatic polyurethane). Do not collapse the two cool-roof names. ETA 06/0263 and BBA 11/4836 sit on the Impermax 1K family — cite the name the current sheet prints.
However, a white film is not a car-park deck. Do not move this card onto vehicles. Read consumption from the current TDS, then the calculator.
How to schedule an Impermax A solar-reflective roof
See Impermax A, Impermax, roofs, balconies and terraces and documents. Area is sized on the calculator.
Outbound reference: EOTA — European Technical Assessments.
A terrace railing is not a specification. Keep the Impermax A solar-reflective roof on the aliphatic 1K.
Therefore the current TDS remains the source for mix and overcoat. A number invented here would be a specification error.
These notes do not replace the current TDS, SDS or a written specification. For pack sizes, mix ratio and kg/m², read the current sheet, then the calculator.
