Wienerberger Porotherm HP 150 Hollow Clay Block: Thinner Profile for Versatile Infill Walling

Optimize your walling with the Wienerberger Porotherm HP 150 Hollow Clay Block, a specialized thinner variant in Wienerberger India's acclaimed Porotherm range – the global leader in sustainable clay building materials. These horizontally perforated (HP) hollow clay blocks are tailored for non-load bearing infill masonry where reduced wall thickness (150mm) is desired, such as internal partitions or space-constrained external infills in RCC-framed buildings. Lighter and more efficient than traditional options, one HP 150 block covers significant area quickly, minimizing mortar, plaster, and overall construction time while delivering superior natural insulation.

Key Features & Specifications

• Material: Pure natural terracotta clay with eco-additives (e.g., coal ash, rice husk) – horizontally perforated for balanced strength and lightness.
• Dimensions: 400 mm x 150 mm x 200 mm (Length x Width x Height) – equivalent to 16" x 6" x 8".
• Weight: Efficient 8.8 kg per piece, further reducing structural loads compared to thicker blocks.
• Density: 733 kg/m³ – lightweight yet dense enough for durability.
• Fire Resistance: Solid 120 minutes (2 hours) – enhanced safety for residential and commercial spaces.
• Compressive Strength: Typically ≥3.5-5 N/mm² – reliable for infill applications.
• Water Absorption: Controlled ~15% – resists moisture without excess retention.
• Thermal & Sound Insulation: Air-trapping perforations provide good U-value reduction and noise dampening (~40-45 dB).
• Origin: Produced in India by Wienerberger, leveraging over 200 years of global expertise in clay solutions.

Why Choose Wienerberger Porotherm HP 150 Blocks?

• Space & Load Optimization: 150mm thickness saves interior space and cuts dead weight, ideal for partitions or where 200mm is excessive—potentially reducing foundation/structural costs.
• Comfort & Efficiency: Natural clay perforations ensure cooler interiors, better acoustics, and breathability for healthier living.
• Rapid, Resource-Saving Builds: Large format + tongue-and-groove design slashes mortar use by up to 65%, speeds construction 2-3x, and pairs perfectly with DryFix adhesive for water-free bonding.
• Proven Safety: 120-minute fire rating + seismic-friendly lightness enhances building resilience.
• True Sustainability: Low embodied carbon, fully recyclable, made from de-silted natural clay – contributes to IGBC/GRIHA green ratings.
• Versatile Use: Excellent for internal walls, thinner external infills, and multi-story projects (up to high-rises).

Suited for non-load bearing applications in homes, offices, hospitals, and high-density developments, Wienerberger Porotherm HP 150 blocks offer thinner, smarter walling that aligns performance with planetary care. Embrace enduring clay innovation for modern Indian construction.
