MANUFACTURING:



Panelman specialises in the manufacturing of insulated panels and doors to form insulated structures.


  • insulated panels
  • insulated doors
  • insulated structures


Panels are manufactured to any length and consist of two pre-stressed skins permanently bonded to fire retardant Polystyrene, Polyurethane or Rock-wool in press by using a heat polymerizing adhesive.

fire retardant Polystyrene

Lamination under pressure with 100% adhesive coverage gives the panel its impressive strength characteristics. These panels combine the strength of a male/female joint with the insulation properties of a snug core to core fit. Various facing materials and finishes are available with frost white chromodeck as a standard. Typically, these panels are 1185mm wide with a thickness ranging from 40mm to 300mm.

Lamination under pressure

They are normally packed on pallets and can be unloaded in most situations using ordinary forklifts.

EXPANDED POLYSTYRENE PANELS (EPS):

EXPANDED POLYSTYRENE PANELS

Polystyrene is generally used in panel applications due to its insulation properties and high strength to weight ratio.

All polystyrene used by Panelman is regularly tested to EPSASA standards and contains a flame retardant additive, which restricts the extent of burn but is not classified as a fire stop material.

MINERAL WOOL / ROCK WOOL PANEL (FIRE STOP AND ACCOUSTIC)

MINERAL WOOL / ROCK WOOL PANEL

Mineral wool is a high quality resin bonded core material. Mineral wool panels offer a significant contribution towards improved fire safety.


If exposed to fire, Mineral wool panels will not release dense smoke and will withstand temperatures in excess of 1000°C. It is a food safe fire stop panel as well as CFC and HCFC free. Mineral wool panels will meet the fire resistance requirements for compartmentation given in the LPC Design Guide for fire protection of buildings. Fire Class A1, according to EN 13 501 Non-combustible – tested to SANA 10177-5. Mineral wool panels is mainly used for data centres and generator rooms due to its excellent fire resistence and accoustic properties.

POLYURETHANE PANELS

POLYURETHANE PANELS (PU) (PIR)

Polyurethane used are made from fully cured foam slabs thereby ensuring they are flat and not subjected to further shrinkage when cut.


It is CFC free but not HCFC free. Even though PU is not non-combustible, it does not burn in the same way as other foams such as polystyrene. Polyurethane when subject to fire forms a carbonaceous layer which retards further flame spread and penetration but being an organic compound will eventually burn.

Panelman also manufactures hinge, sliding and uplift doors finished in anodized aluminium. Door and window frame kits are also available and supplied pre-mitred.


Panelman has a wide range of extrusions that enable the company to be separated from the competition, ensuring the highest quality.

  • The doors are of robust construction and durable with the same insulation and cladding as the wall panels
  • All doors have aluminium extrusion that fits precisely round the doors, with silicone gaskets
  • All doors are fitted with internal safety release mechanisms. (doors can be opened from the inside although locked on the outside)
