The demand for energy efficient, sustainable development has increased significantly in recent years as a result of social pressure and legislation. This has resulted in access to important information concerning the environment plus the impact which building materials and products have on our surroundings.


Insudek expanded polystyrene blocks are an excellent insulator as air is a poor conductor of heat (as long as it is not allowed to move). EPS is 98% air therefore it offers exceptional insulating qualities. EPS’s exceptional cushioning and thermal properties result in lower damage rates and maintain a secure cold chain for temperature-sensitive products.

The Greenhouse gas emissions of plastics, including Polystyrene, are 76% less than other, alternative materials. Insudek Blocks use Pentane as blowing which is a naturally occurring chemical like methane. It is formed by natural processes including the decomposition of plant matter and digestive tracts of animals.


Manufacturing Insudek blocks does not pollute water, be it during production, usage or destruction. EPS is accepted in use with various types of building material and complies with regulations for building and construction performance.


Insudek blocks are one of the lightest of all slab construction materials allowing ease of handling and faster construction times. The outstanding thermal insulation properties and durability ensure performance throughout the full lifetime of the building/construction application in which it is used.
