Extruded Polystyrene Thermal Insultaing Boards

Esscofoam range of products are manufactured to comply to the requirements of astm c-578-95 and bs 3837:part 2:1990

Extruded polystyrene  insulated Boards for roof, cavity walls and floor applications 

The “Inverted Roof” Concept is done using Esscofoam 35,26 & 21 RF

Problems with Conventional Roofs:

In areas of extreme climatic conditions, the waterproofing membrane in the conventional roof is continuously subjected to tremendous stresses caused by temperature extremes: the great

success of the “inverted Roof” concept is that it protects the membrane from all kinds of stresses.

Why Esscofoam?

The “Inverted Roof” system posesses characteristics which Esscofoam 35, Esscofoam 26 and Esscofoam 21 RF with shiplapped edges posess:

  • Closed and uniform cell structure
  • Extremely low moisture absorption
  • Very good mechanical strength
  • Long-term high insulation, performance efficiency
  • Good dimensional stability
  • High resistance to temperature cycling
  • High resistance to ageing
  • High resistance to rotting

Installation Recommendations For The Waterproofing Membrane

  • The membrane shall be laid directly on to the concrete deck
  • If the concrete deck surface is rough, it is advisable to install a protection sheet underneath the membrane.
  • The membrane shall be free of solvents which could attack extruded polystyrene foam.
  • The waterproofing membranes shall be of good quality.

Esscofoam 35, Esscofoam 26 or Esscofoam 21 RF Insualtion

Esscofoam 35, 26 or 21 RF insulation boards shall be laid loose over the membrane, with tight staggered joints.

 

Protection Layer

Paving slabs or gravel shall be laid loose over Esscofoam 35,26 or 21 RF to protect it from wind uplift, buoyancy and UV radiation. In the case of gravel, gravel sizes of 15-30 mm in diameter shall be used and the gravel layer depth shall be a minimum of 50 mm.

 

Cavity Wall Insulation With  Esscofoam 21 CW

Esscofoam 21 CW offers all the advantages of extruded polystyrene insulation at a substantially lower cost, making it highly cost-effective and lower in density.

 

Major Characteristic Advantages of Esscofoam 21 CW

Very high resistance to water absorption.

  • It does not require a vapor barrier.
  • It is not affected by cavity masonry wall construction.
  • High long-term insulation value.
  • Protects the inner walls from condensation.
  • Strong rigid board, not easily damaged
  • Easy to handle, cut and install.
  • The boards are specially long to help cover more areas   and therefore reduce installation time and cost.
  • Available in a wide range of thicknesses.
  • It has Tongue and Groove profiles on all four edges  to eliminate thermal bridging.
  • It does not rot or settle.
  • It is extremely cost-effective in cavity wall applications.

Installation

Esscofoam 21 CW boards are installed with the long edge horizontal and fixed to the inner wall, either mechanically through the use of wall ties, or bonded with a recommended adhesive.
