Cobra 610 Insulated Sectional Overhead Door

Superior thermal performance - optimal opening size Download
L20 Spec.

The Cobra 610 is an insulated sectional overhead door with a guaranteed high thermal performance. It insulates better than current building specifications with less cold-bridging when compared to traditional roller shutters.

Sectional overhead doors slide away fully up and over the top of the opening. They leave the opening completely free, which makes them ideally suited for goods doors in warehouses, factories and storage areas.

Sectional overhead door technical specification

Technical Specification Cobra 610

Insulated sectional overhead door


Manufactured from hinged panels 40mm thick x 610mm high. The panels are made from 39mm thick rigid polyurethane foam and covered inside and outside by 0.5mm thick hot-dipped galvanised steel sheets. The inner and outer sheets are 'V' grooved to provide increased lateral strength.

The whole door has a low density, compressible foam at the panel base, and a factory applied weather seal at the bottom edge.

The panels are fitted with pre-punched galvanised steel end caps and the top and bottom panels are finished with an aluminium retainer which holds the top and bottom EPDM rubber seals.

All metal components on the door are galvanised for weather protection.

Thermal performance:

HVP's sectional overhead doors have a 'U' value of 0.6 W/m2 K.


Insulated door panel to give a sound reduction of (Rw) 25db. Please note: this is for the panel only, and does not include joints, i.e. a fully installed door.

Fire Resistance:

Thermal bow:

If the sectional overhead door will be positioned where it is likely to receive direct sunlight, dark colours should be avoided due to the potential of thermal bow.

Doors accidentally damaged, can easily be repaired using replacement materials and components.

Vision panels can be incorporated in varying sizes.

Excellent insulating properties

The thermal performance of our Insulated Sectional Door panels is better than the current specification in Building Regulations. The 1995 edition of Building Regulations Approved Document L 'Conservation of Fuel and Power' defines the 'U' value requirements for vehicle access on similar large doors as 0.7 W/m2 K.

U-value measures conduction, so lower values are better as they mean less warmth passes through. Our insulated sectional doors have a 'U' value of 0.6 W/m2 K.; better than stipulated by Building Regulations.

Industrial Sectional Overhead Doors

The Cobra 610 is an industrial sectional overhead door. It can be used on warehouses, loading bays, factories, storage spaces, etc.
