PU-foamed sectional doors are available either with 42 mm depth or with sections with thermal break and 67 mm depth. For both versions, the door appearance is 100 % matching.

Depth 42 mm
Hörmann sectional doors with 42-mm-thick PU-foamed sections are especially robust, offering good thermal insulation.

67 mm depth with the best thermal insulation
With the SPU 67 Thermo’s 67 mm sections with thermal break, you benefit from an excellent thermal value of up to 0.51 W/(m²·K)*. The thermal break between the exterior and interior of the steel sections also reduces the formation of condensation water
on the inside of the door.

The surface finish of the sections of steel doors or doors with bottom sections is based on hot galvanized sheet steel and a high-adhesion primer coating (2-component PUR) that protect the door against adverse effects of the weather.

Resistant Stucco surface
Additionally, Stucco texturing gives the door surface a  uniform structure on which light scratches or traces of dirt are more difficult to see.

Micrograin surface finishes give an elegant look
Micrograin features a smooth surface and characteristic fine lines. This door surface finish harmonises especially well with modern facades that are characterised by their clear formal structure. The inside of the door is Stucco-textured in Grey
white, RAL 9002, as standard.

Whichever door type you have selected for your building: At Security Direct, you will find the track application to match your door. Depending on the building architecture and requirement, you can choose between standard and low headroom track applications, low headroom track applications or inclined track applications.

ThermoFrame optionally available for all industrial sectional doors

 Well-insulated industrial sectional doors are essential in heated buildings. This is why Hörmann industrial sectional doors come with an optional ThermoFrame frame connection with a thermal break between the frame and brickwork.

The lip seals on both door sides and the top section of the door provide additional insulation. This way you can decrease the thermal value by up to 21 %.

  • Thermal break between the frame and brickwork
  • Additional seals for improved tightness
  • Easy to fit along with the door frame
  • Optimum corrosion-protection of the side frame
  • Up to 21 % better thermal insulation with the SPU 67 Thermo industrial sectional door with a door surface of 3000 × 3000 mm

The Insulated Industrial Doors are available in Manual Chain Operation, Single (240V) or 3 Phase (415V) motors available.  This depends on the Size of the opening, the usage the door will be operated and if the shutter s face or reveal fixed.


CHAIN OPERATION  -   This is ideal when there is no power on site ie; agricultural buildings.  Chain operation is only available on the 77mm Insulated Lath and you are limited to the size of door it can operate.  Chain operation is usually more expensive than an electric operation.

SINGLE AND 3 PHASE MOTORS  -   We have a range of Single (240V) and 3 Phase (415V) motors.   The motor is selected depending on the Size of the Door, Operation per Hour, Operating Speed, Track Type and Room available for the motor.

The primer-coating of all industrial sectional doors from Security Direct are available in 10 preferred colours, as well as RAL and NCS, in many metallic colours as well as acc. to British Standard.*

The 2-component PUR coating on the exterior or on the exterior and interior and the coil coating procedure for double-skinned sections in preferred colours ensure high quality, long-lasting colour. This maintains the attractive appearance of your door.

In addition you can receive the following with optional colour coating: wicket door frame profiles (external), leaf frame and frame of the side doors NT 60 and NT 80 Thermo, aluminium glazing frames, glazing beads, external frame of the sandwich glazings type A (diecast frame) and type D (plastic frame).
