Industrial Doors // Sectional Overheads // Door Specification

The door panel provides the overall Insulated Sectional Overhead Door assembly with its main characteristics and therefore the following detailed information is provided to assist when the door performance needs to be explained.

Composition

The use of quality materials and precise manufacturing controls ensure long service life in normal industrial and commercial applications. All OSA Insulated Door Panels conform to the Building Regulations requirements for Industrial Doors, and the durability of finishes are those specified by our steel suppliers technical specifications department.

• Outer and Inner Sheet:
  0.5mm hot dipped galvanised steel. Both inner and outer sheets are supplied “V” grooved to provide increased lateral strength, and the whole panel is made-up to form a “T+G” joint top and bottom. Reinforcing strips are fixed internally to ensure secure fixings for the roller carriers and hinges.
• Core:
  39mm thick rigid polyurethane foam, density 40kg/m3.
• Seal:
  Low density compressible foam at panel base, and PVC Tape to the panel nose, all factory applied.

Thermal Performance

Sectional door panels provide high levels of insulation. The foam core between the inner and outer steel sheets of the door panel creates effective interruption of cold bridges, thus preventing transmission of heat or cold.
