The Hormann LPU 42 M Ribbed Silkgrain® sectional garage door is stylish and sleek - eminently suitable for the traditional or modern style property. The clean lines created by the medium ribbing (1 horizontal rib per panel) fit particularly well with contemporary designed houses but in traditional and muted colours will perfectly suit most older and traditional style properties.

The complete door system is available in this design – the garage door, the side door and the front door – seeing them as a suite on the right property creates an absolutely stunning visual effect that has an impressive impact. Furthermore, if there is a need to cover gaps or frames matching profiles provide the perfect solution for a flawless finish. The Hormann LPU 42 M Ribbed Silkgrain® sectional garage door is smooth to touch, silky as the name suggests. The choice between this Silkgrain finish and the wood grain finish is purely down to individual preferences.

The panels are filled with 100% CFC-free rigid PU foam to a thickness of 42mm and with weather resistant seals around all four sides of the door and between the panels the Hormann LPU 42 M Ribbed offers fabulous insulation properties. Insulation in a sectional garage door is ideal for any garage that may be used for anything other than a car!

The Hormann LPU 42 M Ribbed sectional garage door is available in a glorious array of colours and finishes - the Hormann LPU 42 M Ribbed Silkgrain® comes in white as standard with a host of factory and RAL colours being available.
