Hormann LPU 42 Silkgrain Style 450 Garage Door Hormann Steel Sectional Doors

Stunning modernism at its best, the Hormann LPU 42 Design L Ribbed sectional garage door Style 450 is an unusual combination of the smooth silky Silkgrain finish and gleaming stainless steel elements. A neat stainless steel trim with small circular punched apertures at regular intervals sits along the bottom edge of the bottom panel (above the thick lipped weather seal). The stainless steel trim sits proud of the panel by a maximum of 3mm. Surprisingly this minor trimming creates a major impact. The Hormann LPU 42 Design L-Ribbed sectional garage door Style 450 has a matching side door and a matching front entrance door, all with the same trim – viewed as a suite – simply unforgettable!

The engineering and manufacturing standards are stringent, achieving an excellence in build as well as design. Hormann sectional doors are tested and certified in accordance with the high safety requirements of the European Standard 13241-1. Incorporating various safety features – many unique to Hormann - such as finger trap protection, torsion springs that have a patented spring safety device to list just a couple.

The Hormann LPU42 L Ribbed Silkgrain sectional garage door is the absolute ultimate in unconventional design – totally uncluttered panels without any feature whatsoever. The very starkness of this door bestows an exquisite purity to its overall appearance. A classic example of less is more! And although the door is different to the rest of the Hormann range the same stringent engineering and manufacturing standards are maintained.

Fully insulated with the panels having a 42mm filling of CFC-free rigid PU foam and seals around the edges of the door and between the panels, the Hormann LPU 40 L-Ribbed Silkgrain® sectional garage door can make an amazing difference to the garage, especially if it is integral or has a direct entry to the main property. The consequential retention of warmth and stability of temperature will possibly render the garage suitable for other purposes, perhaps as a hobby room or workshop. Certainly, energy will be conserved which must be a plus if power is saved! 

Surface Finish
The finish of the Hormann LPU 42 L Ribbed Silkgrain® door is the most beautiful smooth surface, almost like velvet to touch. On a practical level, the rich appearance is protected with a high quality polyester primer finish. The standard colour is Traffic white with a further 15 factory finished colours available.
