ROOF PANELS

GLAMET

Self-supporting metal panel, insulated with polyurethane, for pitched roofs with a minimum slope of 7% used in industrial and commercial buildings and refrigerated warehouses. Glamet has over lapping joint and are used for roofing & wall cladding.

OVER LAPPING JOINT

  • Over lapping joint ensures the interlocking between the panels. It arrests seepage and also gives additional strength to the panel to withstand all weather conditions and make it walkable.
  • Glamet is in the thickness of 30, 40, 50, 60, 80 & 100mm. All panels are with the cover width of 1000 mm.

HIPERTEC ROOF

Self-supporting insulation panel insulated with rock wool for roof and wall applications, which require a high degree of fire resistance and high degree sound insulation.

The HIPERTEC ROOF panel, manufactured in accordance with a system patented by our manufacturer, consists of a profiled external steel sheet and an internal micro-ribbed steel sheet, with an insulation core of orientated fibre high density rock wool, arranged perpendicularly to the plane of the panel and positioned in strips, laid longitudinally with off-set joints and transversely compacted, in such a way as to completely fill the space between the metal facings.

HIPERTEC ROOF SOUND

The HIPERTEC ROOF SOUND panel is manufactured in accordance with a system patented by our manufacturer and consists of a profiled external steel facing, an internal flat, but perforated liner, with an insulation core of orientated fibre high density rockwool, arranged perpendicular to the plane of the panel and positioned in strips, laid longitudinally with off-set joints and transversally compacted, in such a way as to completely fill the void between the two metal facings.

The ribs of the external metal sheet are filled with shaped mineral wool strips.

BEHAVIOUR IN A FIRE

Establishing the behavior of metal panels insulated with extruded polyurethane in a fire has always been difficult.

Additionally, the complexities of the various National Standards do not the help matters.
This applies particularly to the “Reaction to the fire” and “Resistance to fire” concepts, which define the behaviour of materials.

REACTION TO FIRE

Reaction to fire is the degree to which a material resists combustion.
With regard to this, materials are assigned a class (0, 1, 2, 3, 4, 5): the higher the class, the higher the degree of combustion.

The fire reaction class is established through tests of small sized samples, which are carried out by following extremely strict standards, which vary from country to country.
For this reason, except for Class 0, which is an ISO standard, it is difficult to make any correlation between the classifications accepted by the various national standards.

Class 0

The non-combustibility test to assign Class 0 is carried out to the ISO-DIS 1182.2 standard, which envisages to a very small sample material to 750 C and checking the following.

parameters

  • Formation of flames
  • Increase in temperature
  • Loss of weight
  • In Italy, when the material passes this test, it is assigned Class 0, which in Germany is called A1 and in France MO.

Class 1-5

No organic substances achieve Class 0, so they must be classified with other methods. For the Italian laws, they are:

  • CSE RF 1/75/A – Suspended materials attacked by flames on both sides
  • CSE RF 2/75A – Materials attacked by flames on one side
  • CSE RF 3/75A – Materials subject to one flame and radiant heating
  • Methods CSE RF 1/75A or CSE RF 2/75A are used according to the type of material.
  • The Fire Reaction Class of the product is established by combining these categories.
  • The other European countries classify the fire reaction in a different way.

SOUND INSULATION – SOUND ABSORPTION

The sound level is measured in decibels (dB), which are established by a given sound intensity and pressure, calculated in a logarithmic scale. When the sound is increased (reduced) by twofold the sound level increases (or decreases) by 10 dB.
