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.

Floor Insulation
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.

Interior Fitting

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
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.

About

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.
