Insulated Sectional Overhead Doors

Manufactures 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.


The use of quality materials and precise manufacturing controls ensure long service life in normal industrial and commercial applications. all 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 carrier and hinges.


39mm thick rigid polyurethane foam, density 40kg/m3.


Low density compressible foam at panel base and pvc tape to 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.

colours & finishes (outer skin)

Finished and coloured to match most contemporary building cladding. (inner skin) finished in ral 9010 white, polyester coated, stucco embossed galvanised steel as standard.

We live in a very old property with outbuildings when it comes to exceptional service and professionalism we would not go any where else but to Mark and the team at Staffordshire Industrial doors .Mark provided us with numerous options and profiles to ensure that our doors matched the fabric of the buildings and enhanced them whilst providing security. This level of interaction with the customer is old school and very much lacking elsewhere across this sector .The installation team were excellent they were totally professional and respected the buildings and had pride in their work they are a credit to the firm .The result is a superb installation .
