XPS Sheets – Perimeter Insulation
Perimeter insulation is the thermal insulation of those parts in the building envelope that are in contact
with soil. For more than 30 years, XPS has proven its efficiency in applications as exterior thermal insulation
of walls and floors in contact with soil. The high compressive strength and low moisture absorption as well
as the elasticity and its easy handling at building sites allow the use of XPS within a wide application range

XPS insulation materials are used for exterior thermal insulation of basement walls and basement floors
as well as for floors on the building’s foundation in general. A few XPS products can even be used in groundwater and underneath foundation slabs of buildings. Perimeter insulation with XPS additionally provides protection of the building’s water sealant. Other special products can combine functions of
water drainage protection of sealant and thermal insulation.
Thermal Insulation of Flat Roofs
XPS is mainly used for thermal insulation of flat roofs as inverted roof constructions. According to this construction principle, the insulation layer is positioned above the waterproofing membrane. This has
proven to be advantageous in regard to the durability of the water proofing membrane and of the entire
roof. The waterproofing membrane is effectively protected against thermal and mechanical influences
during the construction and utilization period. This function is especially important for roofs which are to
be used. The thermal insulation above the membrane requires an insulation material that is durable,
resistant against moisture, not biodegradable, and pressure-resistant.
The inverted roof with XPS has been successful for more than 40 years. The continuous development of
XPS and its applications leads to the possibility of using XPS for green roofs as well as for parking decks.
Special products with one-sided mineral coating for retroactive thermal protection-related
refurbishments of flat roofs – so called PLUS roof – are also available.
XPS is suitable for a variety of floor constructions. Products with different compressive strength values
are available. This enables the thermal insulation of floors in offices, shops, and showrooms, as well as the insulation in industrial buildings, warehouses, and refrigerated storage.
In addition to XPS’s high-pressure resistance and its ability to absorb great stresses or tensions, its
elasticity offers a decisive advantage for these applications.
Exterior Wall Insulation
XPS is well suited for the insulation of cold bridges in exterior walls and for cavity wall insulation.
The cold bridge insulation is most important for highly insulated constructions. Beams and pillars in
exterior walls, which have to be made of concrete due to static requirements, need cold bridge
insulation. XPS insulation products with both natural or grooved surfaces, are very well suited due to
their excellent adhesion strength on concrete. Additionally, these insulation boards can be easily
plastered in a professional manner. Due to its high compressive strength and moisture resistance, XPS
is especially well suited for cavity wall insulation. XPS has furthermore advantages for the heat insulation
of large-sized, pre-fabricated concrete sandwich elements for industrial constructions.
Pitched Roof Insulation
Increasing requirements for thermal insulation result in high thicknesses of insulation layers in pitched
roof insulation. However, both the space between the rafters and that below the rafters, is limited for additional insulation material. This is an ideal application for an addition thermal insulation using “above
rafter insulation“. The great advantage of this construction is the closed, cold bridge-free exterior thermal
insulation. Alternatively, an interior “under rafter insulation“ is also possible.
Thanks to its great bending stability, moisture resistance, and the easy handling at building sites XPS
is very well suited for this application.
XPS boards can be used for interior wall and ceiling insulation with plastering for refurbishments. They
are also used as a core layer for tile support elements in sanitary areas. Additionally, composite boards
with different facings made from plaster, plasterboard, wood, plastics, metal and other products are available
Sandwich panels with XPS core layers have proven their efficiency over many years and in different
technical applications: facade panels for buildings and sandwich elements for the automotive industry and
for refrigerated storage constructions. Various metals, wood, and plastics are used as facings.
XPS is well suited as a core layer because of its good shear strength and high tensile strength as well as
its high moisture resistance.
InsuBoard FIRE TEST VIDEO
InsuBoard (Pty)Ltd was established with the objective to manufacture extruded polystyrene boards
(XPS boards).We purchased an extruded polystyrene plant (XPS) that will enable the company to
manufacture insulated ceiling boards in Gauteng Province.
Insuboard (Pty)Ltd will be manufacturing insulation boards that are an environmentally friendly
product for the insulation of walls and ceilings for houses, schools, clinics and commercial buildings..
The boards are also utilised for the manufacture of cornices.
The objective will be to offer insulation that complies with the new building regulation code SANS 204
Energy Efficiency in Buildings, this will reduce the carbon foot print and the end result is the reduction
of the use of electricity.
The company plans to develop into a leader and services provider for the building industry, to provide
panels which is economical and energy efficient. This meaning having the best and most efficient
facilities, processes, and people. To achieve this, Insuboard will invest in ways that will pay off in
competitive advantages for its customers, such as structural plan review, including pre-job and in
job training and aftermarket sales and services. The ultimate goal is to meet these needs and to
continue to improve the company.
Our objective is to provide a high quality ceiling system with the benefits of
insulation which will eliminate the use of heaters in winter and air conditioners in summer.
The objective is to conserve energy.
