Thermo‑Coll: Aerogel Insulating Skim Coat for High‑Performance Summer Protection

Thermo‑Coll: Thin‑Layer Thermal Insulation for Modern Buildings

Rising ambient temperatures and stringent energy codes demand materials that guarantee indoor comfort while minimising energy use. Thermo‑Coll meets this challenge with an aerogel‑based formulation offering one of the lowest thermal conductivities on the market (λ = 0.018 W/mK), creating an effective “thermal jacket” in a few millimetres.

What is Thermo‑Coll?

Thermo‑Coll is a pre‑blended thermal insulating skim coat made of aerogel and water‑based polymer binders. Thanks to its nanoporous structure, it forms a continuous thermal barrier that blocks solar heat gains and improves building energy performance with minimal added thickness.

Key benefits

• High thermal insulation in layers of only 3–8 mm

• Mitigates summer overheating even on sun‑exposed façades

• Ready‑to‑use paste for fast, clean application

• Compatible with new and existing renders, EPS systems and other insulation boards

• Suitable for interior and exterior use, including occupied spaces and heritage buildings

Technical specifications

• Composition: aerogel + water‑dispersion polymer binders

• Thermal conductivity: λ = 0.018 W/mK (CMR Vicenza certified)

• Available grain sizes: 0.5 mm and 1 mm

• Appearance: white, slightly textured

• Packaging: 16 kg buckets

• Compliance: CE mark to EN 15824

• Application tools: notched trowel or float

Recommended application cycle

1. Prepare a clean, dry, sound substrate

2. Apply nano‑emulsion primer

3. Spread Thermo‑Coll evenly

4. Embed glass‑fibre reinforcing mesh

5. Finish with a smoothing layer and, if required, a breathable paint

Typical uses

• Interior energy retrofits without evacuating occupants

• Sun‑exposed façades subject to intense solar radiation

• NZEB projects and conservation areas

• Upgrading existing ETICS systems without increasing thickness

• Window reveals and other thermal‑bridge hotspots
