Cobra 610 Insulated Sectional Overhead Door
Superior thermal performance - optimal opening size DownloadL20 Spec.
Sectional overhead doors are available in a range of various sizes, from small, round windows to fully glazed doors.
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.

Technical Specification Cobra 610
Insulated sectional overhead door
Construction:
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.
Acoustics:
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:
Facing materials used on composite panels to have a Class 1 surface spread of flame to BS 476: Part 7: 1971 and Class O as defined by the Building Regulations 1985.
Track:

The internal liner skin is finished in RAL 9010 white, polyester coated, stucco embossed galvanised steel as standard. Other colours are available on request.
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.

- Chain Hoist or Electric operation: 7000mmW x 7000mmH
- Maximum door area: 42 m2. Contact HVP for doors higher than 5500mmH.

We fit a cable break safety unit as standard on all electrically operated sectional overhead doors and as an option on all doors.
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.
