The advantages of the
liquid sealing
system
without removal
A lightweight liquid sealing solution that avoids removal and reinstallation. It allows for significant savings without interrupting your operations.
adhesion
With its flexibility, the liquid sealing membrane adapts to all project configurations. It adheres to most existing surfaces.
sealing
Seamless sealing, without joints. The risks of infiltration and leaks are reduced. A uniform protection to extend the lifespan of your roof.
reflectance
White coating with high albedo. Sun rays are reflected back into the atmosphere. The building reduces its temperature and its air conditioning consumption.
How Cool Roofing
actually works
Without
Drylast
Heat is absorbed by the roof. The building warms up. Energy consumption increases through air conditioning.
With
Drylast
Sunlight is reflected back into the atmosphere. The building reduces its energy consumption through passive air conditioning.
Techné — 2022
Since the Drylast treatment, we have had no leaks and we have noticed a 30°C temperature drop on our roof this summer. It’s amazing !
