Thermal Insulation Mortar

Lightweight Thermal Insulation Mortar for Building Wall & Roof

Caberry Thermal Insulation Mortar is a functional building material blended with lightweight thermal aggregates such as vitrified microspheres, expanded perlite, EPS particles, together with cement, gypsum and other binding materials. It is widely used for thermal insulation and heat insulation of building walls and roofs.

It features stable thermal resistance, crack resistance, fire retardancy and convenient on-site mixing, suitable for new construction, renovation and energy-saving retrofitting projects.

• External & internal building walls for thermal insulation and energy saving
• Roof thermal insulation, heat insulation and energy-saving renovation
• Residential buildings, commercial buildings, industrial plants

Excellent Thermal Insulation Performance

Lightweight aggregate structure effectively reduces heat transfer, lowers building energy consumption for cooling and heating.

Fire Retardant & Safe

Good fire-resistant property, meets the fire safety requirements of exterior wall insulation systems.

Strong Compatibility

Compatible with cement substrates, concrete, masonry walls, matched with interface agent to reduce hollowing risk.

Good Crack Resistance

Reasonable particle grading, low shrinkage, reduces surface cracking under temperature changes.

Simple On-Site Construction

Ready-mixed powder, only mix with clean water; easy plastering operation for workers.

Stable Durability

Resists aging, moisture and climate erosion, maintains long-term insulation performance.

Note: Technical indicators can be adjusted according to local energy-saving standards and project requirements.

1. Substrate Treatment

   Ensure wall flatness, remove floating dust, oil and grease. Repair cracks with cement mortar or interface agent. Apply interface agent to improve adhesion and prevent hollowing.

2. Mix the Material

   Follow the mixing ratio: powder to water 1 : 0.9~1.1. Add water first, then powder, mechanically stir for 3–5 minutes until homogeneous without lumps. Let it stand for 5 minutes, stir again, and finish application within 2 hours.

• Do not construct on frozen, wet, loose or contaminated substrates.
• Control the mixing water ratio; excessive water will reduce strength and insulation performance.
• Mixed mortar must be fully used within 2 hours; discard expired mixture.
• Follow local exterior insulation system standards for thickness and mesh cloth matching.
• Avoid construction in heavy rain, strong wind or extreme temperature conditions.

• Package: Woven bag; OEM / private label packaging is acceptable.
• Storage: Keep sealed, dry, ventilated, away from moisture and rain.
• Trade Terms: EXW, FOB Guangzhou, CIF, DDP available.
