Traditionally, it has been thought that the application of sandwich panels with polystyrene or polyurethane insulation has been limited to cold stores (large and small) and refrigerated vehicles, but this is certainly not the case. In recent years, polystyrene sandwich panels with outer skins of Chromadek, aluminium, GRP and even stainless steel have been used for a wide range of other applications. Low cost housing, food processing plants, complete abattoirs, mobile office accommodation for construction sites, chicken breeding houses, field clinics and temporary staff accommodation are but a few of the many structures erected with insulated sandwich panels.
Many of the applications just mentioned, require large volumes of panels and are needed over a relatively short time span. The volumes required and delivery period, needs a panel manufacturing facility of high through put with consistent high quality. The automatic panel manufacturing plant of Isowall, with a production rate of 5.5 linear meters per minute, meets these very demanding requirements.
Isowall, who have been in the panel manufacturing business for the past 45 years, also have the expertise and experience to support their products in any of its wide applications. Projects outside of cold storage that have been successfully completed with Isowall insulated panels, include chicken houses, schools, houses, bank buildings, factories, telecommunication shelters, clean rooms, spray booths and many others.
The Isowall structural composite panel consists of a core of thermally efficient insulation material sandwiched between two outer pre-stressed skins and bonded to them. This gives the panel its impressive strength characteristics. Various facing materials and finishes are available.
Insulated sandwich panels are chosen above conventional building materials and methods because of a wide variety of benefits.
Insulated panels reduce the cooling or air conditioning loads of a building or enclosure in hot weather and the heating load needed in winter, e.g. chicken houses in cold weather.
The sandwich panels are easy to erect and do not require special equipment to install. Single panels can be manufactured to any length, but are generally restricted to the length that can be legally transported by road.
Sandwich panels are easily stored on a construction site as compared to bricks, sand, stone, mortar and timber. With the Isowall panel making plant, each panel is marked for ease of identification.
Once erected and completed, sandwich panels do not need painting and can be easily kept in a hygienic condition, particularly as required for food processing plants or abattoirs. The skins of the panel can be pre-painted Chromadek, stainless steel or aluminium as required for the level of hygiene or corrosion resistance. The inner and outer skins can also be of different materials.
Isowall panels are also that much easier to erect, as all panels are automatically mass produced and are uniform in profile, thickness, length and width, according to customer specifications.
The Isowall plant, situated in Silverton, Pretoria, is equipped to supply small or large quantities of panels for any application and at a rate which will meet most projects.
