Sectional door
vs
Roller door
Two doors with no external projection, but two very different logics under the ceiling. The sectional pushes horizontally back with rails under the ceiling; the roller rolls vertically inside a box above the lintel. One wins on insulation and finishes, the other on ceiling clearance. This comparison analyses 8 technical criteria with Hörmann LPU 42/67 and RollMatic figures.

8 criteria unpacked
Each criterion is evaluated on Hörmann official technical figures and our Luxembourg field experience. The badge indicates the door winning the category - a tie means both meet the need equally well.
| Criterion | Sectional (LPU 42/67) | Roller (RollMatic) | Advantage |
Thermal insulation | Double-wall panel 42 or 67 mm PU injected. LPU 42: U = 1.3 W/m²K installed door (panel 0.53). LPU 67 Thermo: U = 1.0 W/m²K installed door (thermally broken panel 0.31; 0.91 with optional ThermoFrame). | PU-foam-filled aluminium profiles. Hörmann publishes no U-value for the RollMatic, which is designed first for space saving rather than insulation. | Sectional |
Ceiling clearance required | Horizontal rails under ceiling on full retraction length (~ door height). Minimum headroom (motorised door): 210 mm with N track, 115 mm with Z and L tracks. | No horizontal rails: curtain rolled into a box above the opening (headroom of 290 mm, 335 mm for doors over 2,300 mm high). Ceiling completely free. | Roller |
Pedestrian access & partial opening | Programmable partial opening via SupraMatic for ventilation or cycle pass. Integrated wicket door optionally possible. | Partial opening possible but the fully unrolled curtain stays in front of entry. No integrated wicket: separate pedestrian access required. | Sectional |
Maximum dimensions | LPU 42: up to 6,000 × 3,000 mm. LPU 67 Thermo: up to 5,000 × 3,000 mm. Suited to wide double garages. | RollMatic: max width 6,000 mm × height 3,100 mm (RollMatic T: 5,000 × 3,100 mm). Comparable widths. | Tie |
Installed price Luxembourg | Free quote on request. Entry-level RenoMatic generally more affordable, LPU 67 Thermo with Decograin wood finish at the top end. Motor and removal itemised in the quote. | Free quote on request. Generally more expensive than an entry-level sectional of the same width, especially in special colours or large sizes. | Tie |
Motor & connectivity | SupraMatic 4 or ProMatic 4 BiSecur on a rail; Apple Home, Google Home and Alexa via the optional WLAN gateway. Operator suspended under the ceiling, accessible maintenance. | RollMatic: standard operator mounted outside the box, BiSecur radio (HSE 4 BS transmitter), no Bluetooth or HCP interface. RollMatic T: tubular motor inside the winding shaft. | Sectional |
Opening duration | Opening up to 25 cm/s with SupraMatic 4 (20 cm/s with ProMatic 4). Quiet toothed-belt drive. | RollMatic: up to 11 cm/s opening speed with the standard operator, i.e. a noticeably slower opening than a motorised sectional. | Sectional |
Lifespan & maintenance | Individual panels replaceable. Annual roller greasing, EPDM seal check. | Slats individually replaceable in case of impact. Annual check of the double tension springs (spring-in-spring system) and cables. | Tie |

Pros & cons
Summary of each type's strengths and weaknesses. We stay factual: no artificially inflated criteria, no fake equivalences. Each door has its real usage niche in Luxembourg.
Sectional door
- Thermal insulation down to U = 1.0 W/m²K installed door (LPU 67 Thermo, panel 0.31 W/m²K)
- Entry price on request, generally more affordable than a roller door at entry level
- Programmable partial opening for ventilation or pedestrian pass
- Integrated wicket possible: pedestrian access without opening the whole door
- Approx. 200 RAL colours and 7 surfaces on the LPU 42 (including Duragrain, 30 decors)
- Panels individually replaceable after impact
- Horizontal rails under ceiling on ~ door length (reduced usable height)
- Minimum headroom with operator: 115 mm (Z and L tracks) to 210 mm (N track)
- Heavier panels: operator to be sized to the door area (SupraMatic P4 or H4 for large doors)
Roller door
- No horizontal rails under ceiling: space above vehicle fully free
- Box above the opening: ceiling completely free (required headroom: 290 mm, 335 mm for doors over 2,300 mm high)
- Thin curtain suited to garages with ceiling used (storage, heating, spots)
- Ideal solution for garages with a low or cluttered ceiling, if the headroom allows for the box
- Slats individually replaceable in case of impact or deep scratch
- Undocumented insulation: Hörmann publishes no U-value for the RollMatic, unlike LPU sectionals
- No integrated wicket: separate pedestrian access required
- Installed price generally higher than an entry-level sectional of the same width
- More complex work on the winding mechanism (box must be opened)
For whom?
Your real situation drives the best choice. Here are the 6 most frequent profiles on our Luxembourg sites - find yours.
Garage communicating with heated living areas. Insulation becomes non-negotiable for Luxembourg winter energy bills. Sectional wins clearly.
Low ceiling (2.10 to 2.30 m) or equipped ceiling (heating, mezzanine, storage), with at least 290 mm of headroom for the box. The roller then frees the whole ceiling.
Detached or unheated basement garage, utility use. Insulation becomes secondary, budget comes first. The RenoMatic sectional remains the most economical solution (free quote).
You walk in multiple times a day (bike, bins, tools). Integrated wicket or partial opening of the sectional avoids full door opening.
Old masonry garage renovation where ceiling height is precious. If the lintel offers 290 mm, the roller (inside or outside mounting) keeps the whole ceiling free.
Contemporary home, demand for wood decor or Duragrain surface, BiSecur / HomeKit integration. Only the Hörmann sectional catalogue matches this finish level.
Our recommendation:
sectional by default, roller on precise cases
Across 8 criteria, the sectional wins 4, the roller 1, with 3 ties (including price, on quote for both). It outperforms the roller on insulation, pedestrian access, motorisation and opening speed. For a standard residential garage in Luxembourg, it is the rational default choice - especially if the garage is attached and heated.
The roller remains relevant on one precise case: garage with low ceiling or used ceiling (mezzanine, heating, storage), provided there is about 290 mm of headroom for the box. In these configurations, it frees the ceiling entirely. The real choice comes from your garage geometry, not from theory.
