Product Types

Four Material Families, Complete Coverage

From fire-rated rock wool to high-performance XPS — every insulation type your project needs.

FIRE-SAFE

Rock Wool

A1 fire-rated, non-combustible mineral wool insulation. Excellent thermal, acoustic, and fire performance. Available as rigid boards and flexible blankets. Up to 1000°C melting point.

LIGHTWEIGHT

Glass Wool

Lightweight, cost-effective thermal and acoustic insulation. Available with aluminum foil, kraft paper, or black glass tissue facing. Ideal for interior partitions and ceiling voids.

HIGH-PERFORMANCE

XPS Board

Extruded polystyrene with closed-cell structure — near-zero water absorption, high compressive strength (≥ 200 kPa). The go-to choice for below-grade, inverted roof, and cold storage applications.

ECONOMICAL

EPS Board

Expanded polystyrene — the most cost-effective rigid insulation. Lightweight, easy to cut and install. Standard choice for ETICS (External Thermal Insulation Composite Systems) and sandwich panels.

Applications

Where Insulation Delivers Value

Two core building envelope scenarios where insulation matters most.

Building Envelope

External wall ETICS, curtain wall insulation, cavity fill. Flat roof, pitched roof, and inverted roof systems — meeting global energy codes.

Cold Chain & Industrial

XPS & PU sandwich panels for cold rooms, freezer warehouses, and temperature-controlled logistics. Industrial pipe and duct insulation.
