Polystyrene sheets is a closed cell, lightweight rigid cellular plastic material produced in a range of densities from 13.5kg/m3 and 28 kg/m3 which offers excellent thermal insulation properties. They can be cut into all shapes and sizes or profiled using computer hotwire cut CNC cutting processes. Polystyrene insulation is used across various industries, including civil engineering, construction, packaging applications. It is valued for its durability, ease of handling, and high strength to weight ratios including shock absorbing characteristics.
Foam Insulation Panels – EPS Polystyrene Boards
Foam insulation panels and boards are known for their its excellent thermal insulating properties. Polystyrene sheet applications include thermal insulation systems for all areas of building construction, walls, roofs and sub-floors. Foam board insulation panels can be used for ceiling panels, decorative surfaces, protective packaging, display boards, signage, letters, models, props and stage sets for trade shows.
Foam Technologies stock a range of densities of polystyrene sheets and foam insulation boards (Standard) SL, (Medium) M, and (Hard) H, and VH grades). Standard sheet sizes are 2400x1200mm and 3600x1200mm which can be cut to thickness from 10mm to 600mm. Special custom cut sheet sizes can be ordered with quick turn-around times.

Applications of Foam Insulation Sheets
Construction
Insulation: Polystyrene sheets and foam insulation boards are used as thermal insulation in cavity walls, external wall cladding systems, insulated panels for roofs, under slab or underfloor insulation. The excellent insulating properties help reduce heat gain or heat loss saving energy and reducing energy consumption.
Lightweight Fill Material: Ideal for use as lightweight infill void foam for landscaping, weight reduction, soil stabilisation for retaining walls and roof top gardens.
Packaging
Protective Packaging: Polystyrene sheets are used to protect sensitive and fragile items during shipping. Their cushioning properties help to absorb shocks and impacts.
Marine and Buoyancy
Floating Devices: Foam board is utilised in the construction of floating devices such as buoys and marine applications due to their buoyant properties.
Arts and Crafts
Model Making: The ease of cutting and shaping polystyrene sheets makes them a popular choice for creating scale models, prototypes, and artistic installations.
Geotechnical Engineering
Lightweight Fill: Used in geotechnical applications to reduce the load on underlying soils and structures, especially in areas with weak ground conditions.
Environmental Considerations
Recyclability
Foam Insulation boards are recyclable. It can be processed into other materials, helping to reduce waste.
Handling and Safety
Handling
Handle foam board insulation sheets carefully to avoid damage. Use proper lifting techniques to manage their weight and size and protect the blocks from impacts that could cause deformation.
Safety Precautions
When cutting or shaping polystyrene sheets, use protective gear such as gloves and masks to avoid inhaling dust or debris.
Storage
Store polystyrene sheets in a dry, cool location away from direct sunlight and chemicals that could degrade the material.
Quality Assurance
Polystyrene Insulation boards and sheets conform to the relevant industry standards and building codes. Regular testing for density, thermal conductivity, and compressive strength to ensures consistent product quality and performance across all product categories.
