The Hormann LPU42 L Ribbed Silkgrain sectional garage door is the absolute ultimate in unconventional design – totally uncluttered door 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 rubber weatherseals around the edges of the door and between the panels, the Hormann LPU 42 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! 

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 paint finish. The standard colour is Traffic white with a further 15 factory finished colours and around 200 RAL colours options being available.

Designer Door
The LPU 42 Ribbed panel is used for most of the designer doors from the Hormann standard range of dor options. Its flat surface is ideal for optional stainless steel elements and ultra modern glazing elements too. Design a unique door for your own property and from the ultra high specification aluminium entrance door range you can also get a front entrance door to match the garage door. Many of the standard models offered in the designer doors have a front entrance door with the same glazing or stainless steel elements to perfectly co ordinate your front elevation with a door that you can rest assured is of the very highest engineering standards with the latest locking mechanisms available for ultra high security too.
