Premium Thermal Performance for High-Spec Builds

The 50mm high-density XPS ceiling board represents the highest insulation performance within the Sanboard pine-finish range.

With an R-value of 1.67 m²·K/W, this thickness delivers superior thermal control in both hot and cold climates — reducing solar heat gain in summer and limiting internal heat loss in winter.

Manufactured at a consistent density of 35–37 kg/m³, the rigid closed-cell core ensures structural stability, moisture resistance and long-term energy efficiency.

Designed for high-spec residential, architect-driven and energy-conscious developments where insulation performance is a priority rather than an afterthought.

Production lead time: 3–5 working days.

Nationwide supply across South Africa.

Thickness: 50mm
Thermal Conductivity (λ): 0.030 W/m·K
R-Value (50mm): 1.67 m²·K/W

The increased thickness delivers superior resistance to conductive heat transfer.

• Reduces solar heat gain in high-temperature regions
• Minimises internal heat loss during winter
• Improves indoor comfort year-round
• Reduces HVAC energy demand

This thickness is selected where performance margins matter.
Manufactured with flame-retardant additives.

Fire Classification: B-s1, d1 in accordance with SANS 53501-1 (EN 13501-1)

Although combustible, the material poses no flame spread hazard under standard test conditions. When exposed to fire, it retracts from the heat source and does not produce flaming droplets.

Installation must comply with applicable building regulations. Not suitable where non-combustible materials are required.
