Isothermal Mechanical Engineering supplies EPS (Expanded Polystyrene) styrofoam sheets across Kenya, Uganda, Tanzania, Rwanda, and Ethiopia, serving construction, cold chain, packaging, and agricultural industries throughout the East African region. Our EPS sheets offer reliable, cost-effective thermal insulation and protective packaging for a wide range of applications.
EPS (Expanded Polystyrene) sheets, commonly referred to as styrofoam sheets, are rigid, lightweight foam boards made by steam-expanding polystyrene beads and fusing them together into a closed-cell structure. They are widely used for thermal insulation, protective packaging, and lightweight construction fill because of their excellent insulation-to-cost ratio, ease of handling, and moisture resistance.

Used extensively in wall cavities, roof decks, and ceiling insulation to reduce heat transfer, improve energy efficiency, and lower cooling costs in residential and commercial buildings — increasingly important across East Africa’s growing urban construction sector.
A major application in food processing, dairy, floriculture, and agriculture — insulating cold storage rooms, refrigerated trucks, and walk-in freezers. This is a particularly strong market in Kenya’s flower export industry and the dairy sectors of Kenya, Uganda, and Rwanda.
Used to protect fragile goods (electronics, appliances, glassware) and perishable produce during shipping and handling, thanks to its lightweight, shock-absorbing properties — relevant for the region’s growing horticultural export trade.
Core material in EPS sandwich panels used for prefabricated buildings, cold rooms, and portable structures, sandwiched between metal or other facing sheets — widely used in cold storage construction across the region.
Used as a lightweight, insulating material in suspended ceiling systems for both thermal and acoustic benefits in offices, hotels, and commercial buildings.
Installed beneath concrete floor slabs to reduce heat loss and improve energy efficiency in both residential and commercial construction.
Used as void formers in concrete construction and as lightweight fill in road embankments, reducing load on underlying structures.
Popular in advertising, exhibition stands, and model-making due to ease of cutting, shaping, and lightweight handling.
Used in fish and produce transport boxes, greenhouse insulation, and seedling trays — directly relevant to East Africa’s agriculture, flower, and fisheries export sectors.

What is the R-value of EPS styrofoam sheet insulation?Typically R-3.6 to R-4.2 per inch, depending on density and grade.
What EPS density do I need for roof insulation?EPS 16 is commonly used for general wall and roof insulation, while higher densities like EPS 20–24 are used where additional load-bearing capacity is needed.
What thickness of styrofoam sheet is best for insulation?This depends on the climate and application, but 25mm–75mm is common for wall and roof insulation, with thicker sheets used for cold room panels.
Are EPS styrofoam sheets waterproof?EPS has moderate water absorption (up to 4% by volume) and is not fully waterproof. For high-moisture or below-grade applications, additional waterproofing measures are recommended.
Do you supply EPS sheets across East Africa?Yes — Isothermal Mechanical Engineering supplies EPS styrofoam sheets to Kenya, Uganda, Tanzania, Rwanda, and Ethiopia, serving construction, cold chain, floriculture, and packaging industries.
