What is a Profiled wall?

A profiled wall utilises metal cladding with trapezoidal, sinusoidal or half round profiles fixed to the steel structure of a building.  Cladding panels can be produced in 6 different profiles which can be laid horizontally or vertically and can be manufactured from prefinished steel or aluminium in a vast array of colours; providing a wide choice of aesthetic finish.  Profiles are induced into sheets of material which are fed through banks of forming rollers in dedicated, state-of-the-art production machinery.

Why choose a profiled wall System?

A profiled wall system offers a range of profiles, materials, colours and orientations to give a huge choice of aesthetic finish.  The acoustic and thermal performance of built up cladding using profiled sheeting fully complies with Building Regulations Part L and can be adjusted to achieve specific requirements of the project.  Standard lead times are five days from receipt of cut lengths, depending on the profile and colour.

Insulation material

Quilt insulation, unless supported, will tend to sag. In a vertical orientation system the spacer system runs horizontally, supporting the insulation. In a horizontal wall system the spacer system runs vertically, offering no support. This is overcome by using semi-rigid slab insulation. This is stacked into the system as the external sheet is installed, ensuring continuity of insulation and no risk of sagging. Note that it is common to use a 0.7mm gauge for the outer profile when a wall is laid horizontally, especially if a metallic finish is specified. The installation requires care and skill, and often costs a little more for this reason.blog entry

Fire Wall issues

Wall cladding systems firewall options to be available where there are boundary conditions to consider.  All fire walls must be constructed in accordance with fire testing accredited to BS476, with particular reference to part 22 which tests integrity and insulation ratings. Always consult manufacturer's recommendations, but in general you should always:

• • Fire protect the main steel for the duration of resistance required
  • Use slotted holes and low melt washers for the secondary steelwork which is not fire protected
  • Use an entire system from one source - mixing and matching profiles, spacer systems and components may result in a construction that has not been tested.

  Which Fire Test

  Built up systems normally offer a 4 hour integrity rating, and either 15 or 30 minutes insulation rating (30 minutes is mandatory in Scotland).  BS 476 is an intensive fire test which exposes the system to temperatures in excess of 1000 degrees centigrade for the entire duration of the 4 hour test. This should NOT be confused with LPC approval or the LPS1181 test. LPS1181 is a short duration reaction to fire test - very different to a fire resistance test. Typically the peak temperature is around 1000 degrees centigrade, but is not maintained and the entire test duration is often less than 15 minutes. It does not test a systems performance in a fully developed fire, but only how the system reacts in the growth phase of a fire.

  A much better test is the LPS1208 - which is equivalent to the BS476 part 22. Please ensure that you understand the difference, as many recent prominent fires have been propagated by the use of LPC approved systems containing combustible components. LPC approval is NOT an indication that a product is non-combustible.

  Euroclad Elite Systems have been tested to BS476 Part22, LPS1181 EXTA and EXTB and LPS1208.  Please reference www.redbooklive.com for the specific LPCB certification for individual systems.
