Polytec / Polystyrene Pipes

EPS is a low cost, resilient, and energy efficient method for pipe insulation applications ranging between temperatures of -110°C and 74°C. EPS comes in standard sizes and it can be cut to specification to meet your pipe insulation project requirements. EPS pipe insulation aids in process control, conservation of energy, and personal/equipment protection.

Advantages:

  • Low k-factors for your insulation needs.
  • Lightweight and durable.
  • No long-term R-value loss or thermal drift.
  • No CFC, HCFC, HFC, or formaldehyde.
  • Easy to fabricate.
  • Superior ingress resistance to moisture.
  • Cost effective thermal control is a very high priority in pipe insulation.
  • Foam-Control EPS pipe insulation comes in a wide range of densities necessary to provide energy efficiency, structural integrity, cost effectiveness, and its proven to do so.

Technical Data

  • Roof Insulation.
  • Under Roof Tile Insulation.
  • EPS panels can be fitted aginst the roof battens under the roof tiles for added thermal and acoustic insulation.
  • EPS panels can be fitted above the waterproofing membrane.
  • The CeilDeck Roof Insulation.
  • These systems are available in different thickness and sizes depending on the specification for insulation.
  • Cavity Fill.
  • Underground Floor Slabs.
  • Resistant to vibration.
  • Low mass.
  • Thermally efficient.
  • Recyclable.
  • CFC and HCFC free, physiologically and chemically harmless.
  • Resistant to aging, mildew, bacteria and rot.
  • Easily cut and worked (finetoothed saw and conventional hand tools).
  • Easily bonded.
  • Ensure adhesive is compatible with EPS.
  • Easily painted using high quality acrylic PVA applied by brush or spray.
  • Flame retardant EPS distinctly reduces the flammability and the spread of flame on the surface of foamed articles. This product is self-extinguishing as soon as the ignition source is removed Fire Retardant FR grade (Styrene unfaced) has obtained a B/B1/2/H&V with & without sprinklers when tested in accordance with SANS 428.
  • EPS is not known as a good sound absorbing product due to its closed cell structure and low density. Insulpro CC offers a range of alternative acoustical insulation products if required.
  • CFC free, recyclable, and does not decompose into harmful substances.
  • Polytec does not provide sustenance for rodents.
  • Densities of 15, 20, 24 and 30 kg/m³.
  • Thermal conductivity at 10°C ranging from 0.033 to 0.038 W/m.K.
  • Hardness of 70, 110 and 200kPa.
  • Temperature limitations -110 to 70°C.
  • CFC and HCFC free, physiologically and chemically harmless.
  • Easily painted using high quality acrylic PVA applied by brush or spray.

These systems are available in different thickness and sizes depending on the specification for insulation. Odourless, inert and fully compatible with all standard building materials and components – Resistant to fresh water, salt water, alcohol, weak and certain strong acids, weak and strong alkalis, resistant to most vegetable and animal oils – EPS is vulnerable to ketones, esters, hydrocarbon chlorides, benzol, petrol, fuel and turpentine.
