When it comes to effective and efficient insulation solutions for a wide range of applications, Expanded Polystyrene (EPS) and Hydroboard stand out as popular choices. These materials offer exceptional thermal and environmental benefits, making them go-to options for architects, builders, and homeowners looking to optimize energy efficiency and sustainability.
Expanded Polystyrene (EPS)
Description: Polystyrene, the base material for EPS, is derived from the polymerization of styrene, a result of combining benzene and ethylene. This process produces a thermoplastic material known as polystyrene, which softens under heat and solidifies upon cooling.
EPS is formed by expanding small polystyrene beads with a pentane blowing agent, using steam to create the required density. The pre-foam is then molded into various shapes and sizes or cut into sheets and blocks.
Environmental Sustainability: EPS boasts remarkable environmental credentials, with zero ozone depleting potential (ODP) and zero global warming potential (GWP). It is also recyclable and does not decompose into harmful substances, contributing to a sustainable future.
Features and Benefits:
– Resistance to vibration and aging
– Low mass and thermal efficiency
– Recyclability and environmental safety
– Flame-retardant properties, reducing flammability and spread of fire
– Durability and resistance to water, acids, alkalis, and more
– Rot-proof and does not promote fungi or bacteria growth
Fire Properties: EPS is inherently flame retardant, significantly reducing flammability. It is self-extinguishing once the ignition source is removed.
Acoustic Properties: Due to its closed cell structure and low density, EPS is not known for its sound-absorbing properties.
Applications:
– Insulation for buildings, including walls, floors, and roofs
– Insulation for pipes and vessels to prevent heat loss and condensation
Hydroboard: A Moulded Insulation Board
Description: Hydroboard is a specialized insulation board designed for applications requiring resistance to moisture and compression. Its unique composition, formulated for water resistance, makes it ideal for specific uses like insulation of surface beds, flat roof insulation, and cavity insulation in masonry walls.
Environmental Sustainability: Similar to EPS, Hydroboard exhibits eco-friendly traits, boasting zero ozone depleting potential (ODP), zero global warming potential (GWP), and recyclability.
Features and Benefits:
– High compressive strength compared to standard EPS
– Low water absorption and vapor permeability
– Cost-effective thermal insulation
– Resistance to aging, impact, and various substances
– Similar durability and resistance features as EPS
Fire Properties: Hydroboard, like EPS, is flame retardant and self-extinguishing upon removal of the ignition source.
Acoustic Properties: Due to its closed-cell structure and low density, Hydroboard is not known for sound absorption.
Applications:
– Insulation for brick cavity walls
– Surface bed insulation
– Perimeter insulation
– Flat roof insulation (protected membrane)
Expanded Polystyrene (EPS) and Hydroboard both offer exceptional insulation solutions with unique benefits.
Whether you’re looking for lightweight and cost-effective insulation (EPS) or specialized moisture-resistant insulation (Hydroboard), these materials provide reliable options for a sustainable and energy-efficient future.
Always ensure compatibility with adhesives and paints and adhere to proper handling and storage guidelines for optimal performance and longevity.
