The 5 main types of garage doors
Each type addresses specific constraints of space, insulation and use. A quick comparison - Fermelux installs all 5 in Luxembourg, with a clear preference for the sectional door on attached garages.
| Type | Main advantage | Space required | Ideal for |
 Sectional | Best insulation (LPU 67 Thermo: U 1.0 W/m²K installed door) | No external overhang | Attached garage, villas in Kiem, Belair, Strassen |
 Up-and-over | Robustness and controlled budget | External overhang ~1 m | Large individual garages, village houses |
 Roller | Maximum space saving | Curtain stored in lintel housing | Small urban garages, low headroom Bonnevoie, Gare |
 Side sectional | Partial pedestrian opening | Side wall clearance required | Frequent on-foot access, cluttered ceiling |
 Side-hinged | Traditional aesthetic | Large external overhang | Character properties, renovated farmhouses in the Ardennes |

« Choosing a garage door well means first understanding your project: an attached garage demands insulation that most competitors overlook, while a detached garage does not have those constraints. Start by identifying your profile - everything else follows naturally. »
The 6 criteria to check
Before signing a quote, review these 6 points. They determine 90% of the final result - the perceived quality of your installation, its service life, and your energy bill.
Dimensions & survey
Width × height of the opening + lintel headroom (from 115 mm for a powered sectional door with Z or L track, 210 mm with N track, 60 mm for the RollMatic OD up-and-under door) + depth below the ceiling. A made-to-measure sectional door fits most Luxembourg configurations, even unusual older houses.
Thermal insulation
For an attached garage, aim for a U-value of 1.3 W/m²K for the installed door (LPU 42, 42 mm panels), or even 1.0 W/m²K (LPU 67 Thermo, 67 mm) if the garage is heated. In Luxembourg, harsh winters call for serious insulation - the most underestimated source of savings.
Security against break-ins
Multi-point locking, fall protection, anti-lift resistance, obstacle detection. With a Hörmann operator, LPU sectional doors are protected against being forced up by a mechanical lock in the rail; the LPU 67 Thermo also comes with RC2 burglar-resistant equipment as standard (optional on the LPU 42) - a real plus in residential estates.
Overall budget
The price depends on the range level (from entry level to the premium LPU 67 Thermo with connected motorisation), the dimensions and the options; supply and installation included, on free quote. In Luxembourg, PRIMe House grants may cover part of the cost on eligible projects.
Aesthetics & finishes
Around 200 RAL colours and 7 steel surfaces on the LPU 42: Woodgrain, Slategrain, Silkgrain, Sandgrain, Planar, Decograin (6 finishes) and Duragrain (30 finishes). The door takes up a large part of the façade visible from the street: its look affects the value of your property.
Motorisation
SupraMatic E4 (650 N, up to 25 cm/s, built-in Bluetooth), SupraMatic P4 (750 N, doors up to 15 m², ideal for heavy doors such as the LPU 67 Thermo), ProMatic 4 (650 N, 20 cm/s, standard use). All connect to Apple Home, Alexa and Google Home via the optional WLAN Gateway.
Steel, aluminium or timber?
Three materials dominate the residential market in Luxembourg. Each has its strengths and limitations - here is an objective comparison across the 6 criteria that truly matter over 20 years.

Insulation & Luxembourg climate
In Luxembourg, winters regularly drop to -10 °C in the Ardennes and -5 °C in the centre. A poorly insulated garage door can reduce the temperature of adjacent rooms by 3 to 5 °C and increase heating bills by 10 to 15 %. As the largest opening in the building, the door is the weakest link if not chosen carefully - particularly in high-performance homes where it becomes the main thermal bridge.
Double-skin steel panels filled with CFC-free polyurethane foam deliver the best performance. The standard 42 mm thickness (LPU 42) achieves a U-value of 1.3 W/m²K for the installed door, enough for most attached garages. The LPU 67 Thermo, with its thermally broken 67 mm panels, reaches 1.0 W/m²K installed (0.91 W/m²K with the optional ThermoFrame): the best-insulated door in Hörmann's residential range.
Beyond the panel, perimeter seals and the floor seal complete the weathersealing. On the LPU 67 Thermo, a double lip seal between the panels further limits air infiltration, and the optional ThermoFrame eliminates the thermal bridge between frame and masonry - a key criterion in Luxembourg, where airtightness determines the building's energy class.

« The most important question is not 'which model should I buy?' but 'what is my profile?'. Once you know whether you have a new build, a renovation, a detached garage, a condominium or an urban garage, the recommendation becomes obvious - and it is often a different Hörmann model for each case. »
