Specifications :- Insulated Sectional Doors.

Composition
The use of quality materials and precise manufacturing controls ensure long service life in normal industrial and domestic applications. All our Insulated Door Panels conform to the Building Regulations requirements
for Industrial Doors, and the durability of finishes are those specified by us.

Outer and inner sheet steel

• 0.45mm continuously hot dip, zinc-coated structural steel [95% zinc, 5% aluminium] S220GD + ZA to EN10326:2004 39.1mm and 79.1mm thick rigid Polyisocyanurate [PIR] foam, density 40 kg/m3
  
  
• Seal: Low density compressible foam, factory applied.,

Outer and inner sheet aluminium

• 0.6mm thick aluminium grade 3004H44 to both sides.
  
  
• Core: 39mm and 79mm thick rigid polyurethane foam, density 40kg/m3
  
  
• Seal: Low density compressible foam, factory applied.

Micro ribbed and T&G Panel subject to quantity and availability.

Thermal bow
Due to the excellent thermal properties of our door panels, consideration needs to be given to the temperature differential that exists between the internal and external faces.

The effect known as thermal bow is of no concern in terms of structural performance. It does however require consideration on clearance and deflection. For application for wide doors and dark colours please contact our technical department.

Durability
The use of high quality materials and precise process control means that long service life can be expected in most industrial and commercial applications. Further information on the durability of coatings can be obtained
from our Customer Services department.

Colours and finishes
Steel outer sheet:
can be finished in Plastisol or Architectural Polyester. Plastisol colours have a leathergrain finish. Polyester finishes are all stucco embossed as standard.

Aluminium outer skin:
mill finish, stucco embossed as standard. Colour availability subject to minimum volume.

Inner skin:
finished in white, polyester coated, stucco embossed galvanised steel as standard. A separate list and sample


Fire resistance
The facing materials used on composite panels, when tested independently, have a Class 1 surface spread of
flame to BS 476: Part 7: 1971, and Class 0 as defined by the Building Regulations1985.

Firesafe/Ecosafe
Our Door Panels are now Polyisocyanurate [PIR] as standard. Whilst PIR belongs to the same chemical family as, the industry standard, Polyurethane [PUR] its’ polymer structure delivers enhanced fire performance
characteristics such as being more difficult to ignite and self-extinguishing.

In addition we would also highlight the inherent environmental benefits of our Door Panel such as being HFC, CFC and HCFC and of Zero ODP in line with the Montreal Protocol. Also, by virtue of the blowing agent used in manufacture the insulation core exhibits a
Low Global Warming Potential [less than 5].

Pursuant to the ideology of Sustainable Construction we would also recommend our
80mm thick PIR Panel which provides an
installed/complete door U value of just 0.54 W/m2K whilst also being eminently suitable for coldstore and chillstore applications.

The Panel can manage temperature differences of 40 degrees and is available with a White Foodsafe Laminate Liner at a small cost premium and subject to minimum quantities.
