Thermoboard being installed for under concrete ground floor insulation

THERMOBOARD is a 40mm thick expanded polystyrene (EPS) sheet that is primarily used for thermally insulating concrete ground floor slabs. The standard dimension of the THERMOBOARD sheets is 1200 x 1200 mm.
The sheet edges re tongue and grooved so that they tight fit together and prevent any thermal bridging.
When fitting the THERMOBOARD sheets that they may be glued together using a quick setting EPS adhesive such as EBS’s POLYGLUE.
Steel mesh used in the concrete slab itself can be spaced off the THERMOBOARD sheets with EBS’s high density EPS mesh spacers.
THERMOBOARD can also be used in brick cavity walls and above conventional ceiling boards to thermally insulate these areas.
THERMOBOARD is particularly useful in optimising the performance of under floor heating systems as it stops heat generated form dissipating into the ground.
As EPS is impervious to water THERMOBOARD also acts as a moisture penetration barrier.

Thermopour being used to fill and insulate cavity brick walls.

THERMOPOUR is a dry, lightweight, volcanic glass which is mixed with cement and water to make a pourable slurry which once applied dries to form a thermally insulating barrier in a range of construction applications.                                                                                       THERMOPOUR can be used in the following applications:

  • Brick wall cavity insulating filler.

  • Insulation of concrete roof decks.

  • Under concrete floor insulation

  • Build up screed on concrete floors to provide improved insulation.

  • Insulating plaster on conventional brick and concrete walls.

Depending on the mix ratio used THERMOPOUR can have ultimate strengths ranging from 1,5 -15 MPa.                                          THERMOPOUR has the following advantages:

  • Lightweight and easy to transport and mix.

  • Compatible with Portland cement.

  • Excellent fire resistance and if used in the applications above will improve the overall fire resistance of buildings. Resists spalling during fires.

  • Superior strength to lightweight concretes as does not rely on air entrapment.

  • Low water permeability which helps stop the ingress of water and moisture into buildings.

·     Good adhesion to brick and cement. When used as an insulating filler in cavity walls THERMOPOUR increases the overall strength of cavity walls by binding the two brick skins together and by the residual strength of the product itself.                                                                      THERMOPOUR mixing instructions are contained in the THERMOPOUR data sheet.                                                                       THERMOPOUR is supplied in 10kg/100lt bags.

EBS Polyblock house under construction in the DRC.

EBS POLYBLOCK is an EPS insulated concrete form walling system (ICF).                                                                                                   ICF's have been used extensively worldwide for close to 50 years to construct quick to build, thermally insulated buildings.                                 EBS POLYBLOCK is a hollow EPS building block 1200mm long x 300mm high x 120/150/180mm wide that is filled with concrete and reinforcing steel to build structural walls and is plastered using EBS’s EPS plaster system POLYPLAST.                                                                         EBS POLYBLOCK can be used for:

  •  All types of residential construction.

  •  Public buildings

  •  Perimeter walls

  •  Agricultural buildings

  •  Infill panels for steel frame construction.

  •  High rise developments as partition walling.

The prime benefits of using EBS POLYBLOCK are:

  • Permanent thermal insulation.

  • Lightweight and quick and easy to build accurately.

  • Limited requirement for skilled labour.

  • Cost competitive vs. other construction methods.

  • Structurally sound being 2-3 times stronger than conventional brickwork.

EBS POLYBLOCK is Agrément approved and thus complies with the South Africa building codes and is thus accepted by the banks and municipalities.                                                                                                                                                                                           EBS POLYBLOCK  as a thermally insulating building system assists in meeting the “Energy Efficiency in Building” requirements laid down in the SANS 204/XSA10400 codes of practice.

TASS being installed in residential and commercial buildings.

TASS is an abbreviation for ‘Thermal Acoustic Slab System’.
TASS is a combination of  moulded EPS ‘coffer’ blocks and high tensile, galvanised steel cold rolled channels that act as the support ribs for the EPS blocks in the TASS suspended floor and roof slab system.
TASS acts as a permanent coffer system to support the reinforced concrete element of the slab.
By using EPS blocks in the system TASS provides excellent thermal insulation to buildings.
Other advantages include:   
  •  TASS components are lightweight and quick and easy to install with reduced labour requirement.                                                                Improved sound insulation.

  • Fire performance equivalent to all concrete slabsystems.

  • Fully load bearing.

  • The TASS system comprises 4 different block depths allowing deeper beams to be formed enabling ‘free’ spans of up to 12 metres.

  • The combination of TASS blocks allows beams to be incorporated into the slab depth eliminating the need for down stand beams.

  • The system is dual spanning

TASS was commercially introduced to the South African market in 2003 and its acceptance has grown continually through a wide range of projects in South and central Africa.                                                                                                                                                                            As a thermally insulating system TASS assists in buildings meeting the SANS204/XSA10400 “Energy Efficiency in Buildings” codes of practice.      TASS is fully supported by and in house engineering design service and quotations are supplied within 24 hours from email submission of plans to:

POLYPLAST is a plaster system specifically designed for EPS building systems and is recommended for use with the EBS POLYBLOCK walling system and for TASS ceiling soffits.                                                                                                                                                POLYPLAST is a combination of water based acrylic resins which is mixed with plaster sand and water to form a workable, easy to apply plaster mix.                                                                                                                                                                                                            The advantages of POLYPLAST are:

  • Excellent adhesion to EPS.

  • Does not shrink crack and as the product remains flexible does not crack over time.

  • Takes on the colour appearance of the plaster sand used and can be left with this ‘natural’ appearance or painted.

  • Can be used to repair cracked or damaged plasters on brickwork.

POLYPLAST application thickness is recommended at 6-8mm and at this thickness is cost competitive with conventional plasters at 15-20mm thickness.

EBS POLYJOINT is a range of pre-cut sheets of EPS 100mm thick x 1,200m long at varying heights – 170mm, 255mm and 340mm to suit different concrete slab depths.

EBS POLYJOINT is used for expansion joints in concrete to replace soft board often used in this application. Soft board has the disadvantages of swelling when in contact with water and deteriorating over time.

EBS POLYJOINT overcomes these problems by being dimensionally stable,  impervious to water, easy to cut and place, long lasting and lightweight.

POLYGLUE is a synthetic rubber based adhesive used to bond EPS to itself and to all other clean and dry surfaces such as metal, brick, wood and fibreglass.                                                                                                                                                                                       POLYGLUE functions as a contact adhesive and has the following advantages:

  • Quick drying unlike most acrylic adhesives used for gluing EPS.

  • Touch dry in 15 minutes.

  • Excellent bond strength.

  • Good heat resistance.

  • High initial tack.

  • Does not attack EPS.

POLYGLUE is available in 1 and 5 lt. standard pack sizes.
