Key Advantages

Why Borax Panels Win

Thermal insulation, flame resistance, noise reduction, and a beautiful durable finish — all in one easy-to-assemble composite panel.

Superior Heat Insulation

Closed-cell polyurethane foam delivers the lowest thermal conductivity of any insulation — keeps interiors cool in summer, warm in winter, slashing energy bills.

Light Flame Resistance

Self-extinguishing B1-class foam core retards flame spread, adding a critical layer of fire safety to your building envelope.

Lightweight Construction

Far lighter than traditional masonry — reduces structural load, speeds installation, and needs no heavy lifting equipment on site.

Noise Reduction

Dense foam core absorbs sound transmission, creating quieter, more comfortable interiors even in busy urban settings.

Convenient Construction

Simple tongue-and-groove assembly installs quickly in any weather — not affected by environmental conditions, no wet trades required.

Beautiful & Durable

Decorative pre-coated metal skin stays vivid and weather-resistant for decades — clean lines and a premium finish that lasts.

Composite Structure

Insulation & Decoration, Unified

PU sandwich panels composite a thermal-insulation core with a decorative skin — hung on the wall outside the building to deliver both insulation and a finished appearance in a single assembly step.

Decorative Outer Skin

Pre-coated colored metal — weatherproof, fade-resistant finish.

Polyurethane Foam Core

Closed-cell PU — the insulation and sound-damping heart of the panel.

Inner Backing Layer

Protective inner skin that seals and stabilizes the composite.
