Steel
vs
Wood
Hörmann steel dominates the Luxembourg residential market with its double-skinned LPU sectional doors. Solid wood remains a heritage choice for character homes. One focuses on technical performance and zero maintenance, the other on natural authenticity and noble ageing. This comparison settles it on 8 objective criteria.
Steel door
Insulating, durable, maintenance-free
Solid wood door
Authentic, noble, artisanal
Two philosophies in numbers
Hörmann steel and solid wood do not play in the same league. Double-skinned steel with PU foam delivers 2 to 3 times better thermal insulation, weather resistance without maintenance, and a lower entry price. Solid wood offers unmatched aesthetic charm but demands regular upkeep and costs more. Here are the real figures.

8 criteria materials
Each criterion is assessed against real technical characteristics and our field experience in Luxembourg. Steel = Hörmann LPU 42/67 sectional doors, wood = bespoke artisanal doors in pine, oak or larch.
| Criterion | Steel | Wood | Advantage |
Thermal insulation | Double-skinned 42 mm PU-injected steel panel (LPU 42): U = 1.3 W/m²K installed door. LPU 67 Thermo (67 mm): U = 1.0 W/m²K installed door, 0.91 W/m²K with optional ThermoFrame. | Solid wood 42 mm without PU foam (Hörmann LTH 42): U ≈ 2.9 W/m²K installed door. Wood naturally insulates better than bare metal, but without injected PU foam it remains 2 to 3 times less effective than double-skinned Hörmann steel. | Steel |
Weather resistance | Hot-dip galvanised steel + polyester coating. Withstands UV, rain and frost without notable degradation for many years. No swelling, no warping. | Solid wood reacts to moisture: swelling, shrinkage, potential warping. Sensitive to UV (greying), fungi and wood-boring insects without regular treatment. | Steel |
Maintenance | Soapy water cleaning once a year. No surface treatment required. The polyester coating needs no touch-up as long as it is undamaged. | Stain or varnish mandatory every 2 to 3 years. Light sanding before application. Recurring labour costs apply if outsourced. Neglected maintenance = accelerated degradation. | Steel |
Natural aesthetics | Decograin and Duragrain finishes convincingly mimic wood (Golden Oak, Dark Oak, Night Oak, Winchester Oak…). But it remains an imitation - touch and ageing stay synthetic. | Authentic solid wood charm: unique natural grain, living texture, noble ageing (patina). A character that steel cannot reproduce, even with the finest decors. | Wood |
Price | Free quote on request, from the RenoMatic steel 42 mm to the LPU 67 Thermo Decograin. Wide range, affordable entry level, industrial economies of scale. | On quote for bespoke artisanal work; sculpted solid oak sits considerably higher. No industrial production in Luxembourg; every door is unique. | Tie |
Lifespan | Long lifespan without structural issues. Galvanised steel does not degrade if the paint is intact. Springs and mechanics are the wear parts, not the panel. | Lifespan varies with species and maintenance. Well-maintained wood (regular staining) lasts long, but neglected upkeep drastically shortens lifespan. Wood remains a living material that naturally degrades. | Steel |
Motorisation | Compatible with all Hörmann operators: SupraMatic, ProMatic, BiSecur technology. Relatively light steel panel, nominal drive suffices. | Heavier than double-skinned steel, depending on species and thickness. Requires a more powerful operator and reinforced springs. Hörmann compatibility not guaranteed on artisanal doors. | Steel |
Finish options | Approx. 200 RAL colours, 7 surfaces on LPU 42 (Woodgrain, Slategrain, Silkgrain, Sandgrain, Planar, Decograin 6 decors, Duragrain 30 decors). Decograin and Duragrain decors mimic wood or metal, among others. Very broad industrial catalogue. | Choice of species (pine, oak, larch, chestnut), natural tones, coloured stains, varnishes. Every door is unique. But the range is limited to the capabilities of the local craftsman. | Tie |

Advantages & disadvantages
The real strengths and weaknesses of each material, based on more than 20 years of expertise in Luxembourg.
Steel
- Best double-skin thermal insulation: U = 1.0 W/m²K installed door on LPU 67 Thermo (0.91 with optional ThermoFrame)
- Zero surface maintenance - soapy water cleaning suffices
- Entry price significantly lower than artisanal wood
- Weather-resistant against UV, frost without degradation
- Standard compatible operators (SupraMatic, ProMatic, BiSecur)
- Decograin finishes realistically mimic wood
- Synthetic appearance despite wood-imitation decors
- No noble ageing - the surface remains identical over time
- Standardised industrial production, less artisanal customisation
Wood
- Authentic charm and unrivalled heritage character
- Noble ageing: value-enhancing natural patina
- Natural, bio-sourced material, low manufacturing carbon footprint
- Every door is unique - fully bespoke artisanal
- Natural acoustic insulation superior to steel
- Enhances character homes and listed buildings
- Mandatory maintenance every 2-3 years (stain/varnish) - costly if outsourced
- Sensitive to weather: swelling, shrinkage, warping, greying
- Heavier: reinforced operator and stronger springs required
- Entry price significantly higher than Hörmann steel
- Few manufacturers in Luxembourg - longer lead times, limited after-sales
Which for your project?
The right material depends on your home, your budget and your tolerance for maintenance. Here are the typical profiles we encounter in Luxembourg.
You seek thermal performance and zero maintenance. Hörmann LPU 42/67 with Decograin wood-effect gives you the look without the constraints. The most common choice for new builds in Luxembourg.
Your home has character and deserves a door to match. Solid wood (oak, larch) brings authentic charm that steel cannot reproduce. Accept the maintenance as part of the heritage.
You want the best insulation at the best price. Hörmann LPU 42 steel offers U = 1.3 W/m²K (installed door) at a significantly lower price than artisanal wood at equivalent specification. Price on free quote.
You do not want to sand and stain every 2-3 years. Steel demands nothing - an annual soapy-water wash suffices for many years. Wood punishes neglected maintenance with accelerated degradation.
You are not on-site for regular upkeep. Steel is the only sensible choice - it does not degrade in your absence, unlike wood which requires regular attention.
Your architect has designed a bespoke door to fit into a wood/stone ensemble. Solid wood remains essential for these projects where every detail matters and budget is not the primary constraint.
Our recommendation:
Hörmann steel for standard residential
Out of 8 criteria, steel wins 5, wood wins 1, with 2 ties (including price, quoted on request for both). Hörmann steel dominates on thermal insulation, weather resistance, maintenance, lifespan and motorisation - the criteria that matter most day to day. With Decograin finishes, it even offers a convincing wood-effect without the constraints of the natural material.
Solid wood retains an indisputable advantage on authentic aesthetics. For character homes, listed buildings or high-end architectural projects, nothing replaces the charm of solid oak or larch. But one must accept the maintenance every 2-3 years, a higher price and limited after-sales support in Luxembourg.
