INTRODUCTION TO COMPOSITE PANELS.
COMPOSITE PANELS. The days when an
insulated roof meant building it up with liner trays, micro
zeds, quilt insulation, vapours barrier and top sheet etc. etc
involving high labour costs and the inherent risk of cold
bridging and weak spots are no more.
PROPERTIES and PERFORMANCE.
Environmental. The use of CFC and HCFC
free foam for all standard foam filled composite panel products
irrespective of thickness, clearly demonstrates a responsibility
to environmental issues.
Fire Performance - Profiled Roof & Wall
Panels. Walls: Both faces of the panels are class O in
accordance with the building regulations when tested to BS476
parts 6 and 7. Roofs: External fire exposure tests to BS476 part
3 1975. EXT SAA.
Structural Integrity. The composite
panels by their nature form a composite beam and are therefore
capable of spanning considerable distances, have high resistance
to bending and good shear strength.
Framing Systems - Tolerance of Support
Structures.
Flat panel cladding systems reflect any
inaccuracy in alignment of the supporting structure. It is
therefore recommended that all secondary structural supports to
which Trisomet and Trimapanel are
connected be capable of adjustment during erection to give a
true line and level.
Acoustic Properties - Sound Reduction.
Architectural wall panels have a sound
transmission class rating of 28db for sound transmission loss
tabulated from the frequency range of 100 to 5000 Hertz. The
profiled composite panel Trisomet has a class rating of 25 db
for the same frequency range.
