Insulated Exterior Facade Stucco Coating
Fire Barrier F360 Class
THERMOLOCK Insulated Exterior Facade Stucco Coating is a new generation construction plaster designed to combine thermal, acoustic, and water insulation in a single product. It is classified as A1 fireproof according to EN standards and provides F360 class fire resistance. The F360 class defines the highest level of protection for fire-retardant insulation materials.
The product is specially formulated for exterior applications requiring superior fire safety, thermal,
acoustic, and water insulation. Due to its perlite and inorganic components, it has a breathable
structure and never allows fire or smoke formation. It is also suitable for use on different surfaces.
Advantages
- Fire resistance ≤ 360 minutes
- CE-certified
- High thermal insulation
- High water insulation
- Easy to install
- Smooth finish
- High acoustic insulation
- Suitable for most surfaces
Application
1. The substrate should be clean, free of dust, oil, and weak particles.
2. Mix 20 kg powder with approximately 15–16 liters of clean water using a low-speed mixer.
3. Mixing 6 minutes until a homogeneous mixture is obtained.
4. Allow the mixture to rest for 5-6 minutes for better water integration.
5. Apply manually with a trowel or by machine spraying.
6. For multilayer applications, allow the first layer to dry before applying the next.
7. Protect the surface from direct sun, wind, and frost during curing.
Areas of Application
Wall and ceiling coverings
Houses exposed to water and humidity
Commercial buildings, schools and skyscrapers
- Glass surfaces where insulation is desired
- The outer surfaces of the tiny houses
- Any type of structure requiring insulation
Primer Application
Primer use is required for surfaces other than concrete. The product to be used as primer is Thermolock Adhesion Enhancing Transition Primer. Please refer to the product’s technical data sheet or product documentation for its use.
Storage
- Store in a dry, closed place on pallets.
- Do not stack more than 10 bags.
- When stored this way, it has a shelf life of 16 months.
Safety
Avoid contact with skin and eyes Wear protective gloves and goggles during application. Non-flammable and non-toxic. Classified as a non-hazardous cement-based material. For detailed health information, please refer to the MSDS document.
Sustainability
Thermolock is produced from natural, recyclable raw materials and helps reduce energy consumption, CO₂ emissions, and extend the lifespan of building structures.
It is an ideal choice for green construction projects and environmentally certified buildings (LEED, DGNB, BREEAM).
