Thermaboards | Your National Polystyrene Specialist

Thermaboards (PTY) Ltd is a national supplier of Extruded Polystyrene (XPS) and Expanded Polystyrene (EPS) rigid boards are used for thermal insulation. It is produced from general purpose polystyrene by the process of extrusion or expansion. These sheets have a closed-cell structure and virtually no air-voids in between the cells.

We supply all our XPS and EPS rigid boards, ceiling insulation products and insulating blankets nationwide.

Ceiling Boards | XPS

Extruded Polystyrene is a closed cell polystyrene rigid foam board, with high compressive strength and excellent long-term thermal resistance performance

Polystyrene Blocks | EPS

Polystyrene blocks are used in construction as permanent insulation in buildings. The blocks are energy efficient and ensure optimal insulation not only for walls of buildings, but also the roofs and even floors.

Cornice Profiles | XPS

Our cornices are manufactured from the best high density XPS (Extruded Polystyrene) and are sold in 2m lengths. We have a range of 17 different Cornice Profiles available to choose from.

Perimeter Insulation | EPS

Even if the foundation wall is insulated vertically under the slab, significant heat is still lost from the slab edge that is closest to the cold outside air.

Cavity Wall Insulation | EPS

Expanded Polystyrene (EPS) insulation is effective in reducing the thermal transmittance (U-Value) of the walls of new and existing buildings.

Building Materials | EPS

Polystyrene blocks are used in construction as permanent insulation in buildings. The blocks are energy efficient and ensure optimal insulation.

Combi-Cut & Un-Cut Ceiling Rolls | Knauf

Knauf Insulation Ceiling Rolls (Combi-cut and un-cut) are Glass Mineral Wool rolls, designed for use in cold lofts where pitched roofs are insulated at ceiling level.

Multi-Pack Ceiling Rolls | Knauf

Knauf Ceiling Roll Multi Pack provides the flexibility and convenience of 2 rolls in 1 by providing the option to install at either a 100mm depth or a 50mm depth.

Thermal Insulation For Roofs & Walls | ISOTHERM

ISOTHERM Thermal Insulation is suitable for roofs, walls and geyser insulation. It offers a range of benefits including a reduction of electricity costs and the fact that it is safe and easy to install.

Ceiling Insulation | Sisalation

Sisalation®, when used in conjunction with an airspace, is a highly effective thermal insulating membrane due to the high reflectivity and low emissive properties of the aluminium foil surfaces.

Ceiling Insulation | Spunsulation

Spunsulation Radiant Barriers are a range of products manufactured for all sectors of the construction industry that require reflective insulation foils for roofing, walling and insulation applications.
