Choosing the right roof window manufacturer is a decision that carries real weight for distributors, building-material importers, contractors, architects, and project developers alike. A roof window is never just a glazed opening cut into a roof — its frame construction, glazing, thermal performance, weather resistance, installation system, and the long-term availability of spare parts all shape how well an entire building performs over time.
For professional buyers, finding a reliable Dachfenster Hersteller means looking past price comparisons alone. Manufacturing experience, product range, customization capabilities, quality control, international supply capacity, and technical support often matter just as much.
The global market today includes a mix of long-established European roof window manufacturers and newer players serving international OEM and private-label demand. The list below compares ten notable Dachfenster Hersteller, weighing their manufacturing background, product specialization, market presence, and overall fit for professional buyers.
VELUX Group
Founded
1941, Denmark — VELUX's story starts in 1941, when Danish engineer Villum Kann Rasmussen set out to design a roof window that could turn dark, unused attic space into bright, livable rooms. The first VELUX roof window was patented a year later, in 1942. What began as a handful of Danish projects has since grown into an international building-materials group with a footprint in markets around the world.
Highlights
- More than 80 years of roof-window experience
- International presence across 37 countries
- Strong brand recognition in the European roof-window market
- Deep experience in daylighting and natural ventilation
- Ongoing development of electric, sensor-driven, and smart-home solutions
- Broad product ecosystem spanning both residential and commercial applications
Products
Company Profile
VELUX is arguably the most recognizable name in the global roof-window industry, and its business has grown around a fairly simple architectural idea: bring more daylight and fresh air into a building. Today the company operates internationally, pairing roof-window manufacturing with a much wider catalogue of daylighting, ventilation, and smart-home products. For buyers looking for an established Dachfenster Hersteller, VELUX is often the benchmark — not just for brand recognition, but for how much sits around the core product itself: installation accessories, shading systems, automation, and dedicated technical support. For large distributors and projects where brand recognition drives purchasing decisions, VELUX remains one of the strongest reference points on the market.

Roto Frank Dachsystem-Technologie
Founded
Roto Frank — established in 1935; Dachsystem-Technologie with more than 75 years of market experience. Roto Frank brings a long history in German window technology, and its Dachsystem-Technologie division has grown into a specialist supplier of roof-window solutions in its own right. The division is built specifically around roof windows and related roof-system products for professional markets.
Highlights
- German engineering heritage
- More than 75 years of experience in roof-system technology
- Strong specialization in residential roof windows
- Professional distribution network
- Focus on technical product development
- Broad range of roof-window configurations
Products
Company Profile
Roto Frank Dachsystem-Technologie is a German specialist in roof-window technology and part of the wider Roto Frank group. Its market position rests on three pillars: German engineering, continuous product development, and an established professional distribution network. When comparing a Dachfenster Hersteller, Roto stands out where engineering quality, installation detail, day-to-day operating comfort, and long-term performance matter most in the buying decision. Its positioning is deliberately different from a low-cost commodity supplier — the emphasis sits squarely on technically developed roof-window systems backed by a well-established professional network, which makes Roto a solid benchmark for premium and specification-driven projects.
Location: Roto Frank AG, Roto-Straße 1, 70771 Leinfelden-Echterdingen, Germany
AUROLUX
Founded
2015 — AUROLUX is the roof-window brand of Xuzhou Sunshine Manufacturing Co., Ltd., based in Jiangsu, China. According to the company's own information, AUROLUX draws on more than 15 years of manufacturing experience behind its current roof-window business, and has built a dedicated international supply model around roof windows and skylights.
Highlights
- Professional roof-window manufacturer based in China
- Dedicated OEM and ODM capabilities
- International B2B supply focus
- 50,000 m² manufacturing facility, per company information
- Automated production equipment
- Custom dimensions, finishes, and configurations
- Pitched and flat roof-window solutions
- European-oriented product design
- Products supplied to international markets
Products
Company Profile
AUROLUX presents itself as a professional roof-window manufacturer that pairs modern engineering with architectural aesthetics. Its product strategy spans both pitched and flat roof applications, letting buyers source multiple roof-window categories from a single manufacturing partner. For buyers in search of a flexible Dachfenster Hersteller, AUROLUX offers something quite different from the large European consumer brands — its focus leans heavily toward OEM, ODM, customization, and international B2B supply. The company says it supports global distributors with tailored designs built around project-specific requirements. This manufacturing model tends to appeal most to importers and distributors who need their own product specifications, private-label programs, custom dimensions, or a wider roof-window range without investing in their own production infrastructure. In short, AUROLUX fits a specific procurement need: buyers looking for a professional manufacturing partner rather than simply a retail brand to resell.
Location: Xuzhou Sunshine Manufacturing Co., Ltd., Jiangsu, China
FAKRO
Founded
1991, Poland — FAKRO was founded in Nowy Sącz, Poland, in 1991 by Ryszard Florek, and has since grown from a small family business into an international roof-window group with its own manufacturing companies and foreign subsidiaries.
Highlights
- More than three decades of roof-window manufacturing
- Major European roof-window manufacturer
- International production and distribution network
- More than 3,300 employees, according to company information
- Extensive roof-window and accessory portfolio
- Strong focus on safety, energy efficiency, and product development
Products
Company Profile
FAKRO has grown from a Polish family company into one of the world's major roof-window producers. Its extensive manufacturing structure and wide-ranging product portfolio let it serve both new-build construction and renovation markets with equal ease. What stands out most when evaluating FAKRO as a Dachfenster Hersteller is the sheer breadth of its catalogue. Rather than concentrating on a single window configuration, the company spans multiple frame materials, opening mechanisms, roof applications, and complementary products. That breadth makes FAKRO particularly appealing to distributors who need a full catalogue rather than one specialized product line. Its international manufacturing and distribution footprint also makes it a practical benchmark for buyers looking for a European supplier with genuine global market experience.
Location: FAKRO Sp. z o.o., ul. Węglowa 1, 34-400 Nowy Sącz, Poland
Keylite Roof Windows
Founded
1998 — Keylite built its business as a specialist roof-window manufacturer serving the UK and Irish construction markets before expanding distribution into other parts of Europe.
Highlights
- Specialist roof-window manufacturer
- Strong UK and Irish market presence
- Focus on professional installation
- Practical installation-oriented product design
- Broad range of roof-window solutions
- Established presence in professional building-material channels
Products
Company Profile
Keylite Roof Windows positions itself as a specialist in roof windows rather than a general window producer, and its product development leans heavily on installation efficiency, compatibility with roofing systems, and the practical realities professional installers deal with on-site. For buyers weighing a Dachfenster Hersteller, Keylite is worth a closer look whenever installation speed and contractor-friendly design carry real weight in the decision. Its strong foothold in the UK and Ireland also gives it a distinct place within the wider European roof-window market. For distributors, Keylite offers an alternative to the largest continental European brands — particularly useful in markets where its professional distribution network is already well established.
Location: United Kingdom & Ireland
DAKEA
Founded
2012 — DAKEA launched in 2012 as a roof-window brand built specifically for professional customers. The brand belongs to Altaterra, founded in the UK in 2001, which itself sits within the VELUX Group.
Highlights
- Professional-market positioning
- Focus on value for money
- More than 80 years of roof-window manufacturing experience within its manufacturing background
- 20-year guarantee on qualifying roof windows
- Strong relationships with builders, installers, and merchants
- European manufacturing and distribution infrastructure
Products
Company Profile
DAKEA was set up to put high-quality roof windows within easier reach of professional buyers. The brand's positioning blends product quality with competitive pricing, aimed squarely at builders, roof-window installers, and building-material merchants. For buyers comparing a Dachfenster Hersteller, DAKEA is worth a look whenever the decision comes down to the balance between quality, warranty coverage, price, and professional-level support. One thing worth flagging: DAKEA is a brand owned by Altaterra rather than a fully independent manufacturing group. That's a detail buyers should factor in when weighing supplier ownership, product sourcing, and distribution arrangements.
Location: Europe (Altaterra / VELUX Group)
RoofLITE+
Founded
European roof-window brand with a long manufacturing background — RoofLITE+ is built around roof-window solutions for residential construction and renovation, with an emphasis on practical installation, product performance, and distribution across Europe.
Highlights
- European roof-window market presence
- Residential roof-window specialization
- Practical product configurations
- Professional installation focus
- Complementary flashing and accessory systems
- Suitable for construction and renovation applications
Products
Company Profile
RoofLITE+ serves the European residential construction market, with products built around the everyday realities of roof installation, renovation, daylighting, and ventilation. For buyers on the hunt for a Dachfenster Hersteller, RoofLITE+ offers a more focused alternative to the biggest international brands. It's most relevant for distributors and professional building-material channels that need established roof-window configurations paired with compatible installation accessories. When comparing suppliers, it's worth distinguishing between brand ownership and the actual manufacturing entity — especially when assessing OEM opportunities, production capacity, and private-label cooperation.

LAMILUX
Founded
1909, Germany — Master carpenter Heinrich Strunz founded the company in Rehau, Germany, in 1909. LAMILUX later branched out from timber processing into fiber-reinforced plastics and daylighting systems, and by 1955 was producing GRP corrugated sheets and dome rooflights under its own name.
Highlights
- More than a century of company history
- German family-business background
- Strong specialization in daylighting systems
- Manufacturing expertise in rooflight and building-envelope products
- Industrial and commercial project experience
- Engineering-focused product development
Products
Company Profile
LAMILUX stands apart from typical residential Dachfenster manufacturers because its expertise is concentrated on daylighting systems and rooflights, particularly for commercial, industrial, and architectural buildings. Its roots trace back to 1909, and it began producing rooflight domes under the LAMILUX name in 1955. For a professional buyer casting a wide net for a hersteller dachfenster, LAMILUX becomes relevant once the project goes beyond standard residential roof windows and calls for larger daylighting systems or specialized rooflight solutions. That distinction matters: LAMILUX is best evaluated as a daylighting and rooflight manufacturer, not as a direct substitute for VELUX or FAKRO when it comes to standard residential pivot windows.
Location: LAMILUX Heinrich Strunz Group, Rehau, Germany
KUREDA
Founded
2011, Germany — KUREDA GmbH was registered in Germany in 2011, built from the outset around developing, manufacturing, and distributing roof windows and related accessories. Today its positioning leans heavily on customized roof-window solutions and repair-friendly design.
Highlights
- German Dachfenster specialist
- Focus on repair-friendly product construction
- Custom-made roof windows
- 1-to-1 replacement solutions
- Sustainable material approach
- Direct sales model
- European service network
Products
Company Profile
KUREDA has carved out a distinctive niche in the German roof-window market by focusing on replacement, modernization, repairability, and custom production. The company describes itself as both developer and manufacturer of roof windows, and it sells directly. For buyers seeking a specialized Dachfenster Hersteller, KUREDA earns particular attention wherever off-the-shelf replacement products fall short. Its 1-to-1 replacement concept is built to simplify swapping out older roof windows, and its made-to-measure approach adds another layer of flexibility. The company also puts real weight on repairability — individual components can be replaced rather than forcing buyers to discard the whole window. That gives KUREDA a distinctive edge on sustainability and lifecycle cost.
Location: KUREDA GmbH, Germany
LiDEKO
Founded
More than 100 years of window and door manufacturing experience — LiDEKO roof-window products come from Friedrich Amelingmeyer Metallbau GmbH in Osnabrück, Germany. The company says it has specialized in windows and doors for over a century.
Highlights
- German manufacturing
- Specialization in large-format roof sliding windows
- XXL roof-window configurations
- Manual and electric opening options
- High degree of customization
- Own window testing facilities
- RAL quality certification
- Suitable for premium residential and architectural projects
Products
Company Profile
LiDEKO occupies a narrow but distinctive slice of the roof-window market. Rather than going head-to-head with standard center-pivot windows, the company concentrates on large-format sliding roof windows built to open up significantly bigger views and openings. Manufacturing happens at Friedrich Amelingmeyer Metallbau GmbH in Osnabrück, where the company combines custom glazing, aluminum profiles, manual or electric operation, and oversized dimensions for residential and architectural use. For buyers comparing a hersteller dachfenster, LiDEKO makes the most sense when a project calls for an oversized roof opening, balcony access, loggia integration, or a premium architectural touch. That specialization makes it less of a general-purpose supplier, but a particularly valuable one when standard roof-window dimensions simply won't cut it.

How to Choose the Right Dachfenster Hersteller
Brand reputation or unit price alone shouldn't drive the decision. For professional procurement, a handful of technical and commercial factors deserve real comparison.
1. Manufacturing Experience
A long manufacturing history often points to established production processes, deep product-development experience, and accumulated know-how around roof-window applications. That said, years in business shouldn't be judged in isolation from current production capability.
For procurement teams, the more useful questions are:
- Does the company manufacture the products itself?
- Where are the production facilities located?
- How much production capacity is available?
- Does the company have experience with international projects?
- Can production documentation and quality-control procedures be provided?
2. Product Range
The right product range depends heavily on the project itself. A residential renovation might only call for standard center-pivot roof windows, while a luxury villa may need aluminum-clad wood or large-format windows. Commercial projects, meanwhile, often require flat-roof daylighting systems or custom rooflight constructions.
Before settling on a Dachfenster Hersteller, buyers should compare:
- Pitched roof windows
- Flat roof windows
- Large-format windows
- Roof access windows
- Balcony roof windows
- Electric roof windows
- Smart control systems
- Flashings and installation accessories
3. Materials and Glazing
Frame material plays a major role in durability, appearance, maintenance needs, and thermal performance.
Common options include:
- Timber
- PVC
- Aluminum
- Aluminum-clad timber
- Thermally broken aluminum
Glazing deserves the same scrutiny, judged against project requirements. Double glazing works fine for some applications, while others call for triple glazing, laminated safety glass, acoustic glass, or low-emissivity coatings.
4. Thermal and Weather Performance
Professional buyers should ask for documented technical performance rather than taking marketing copy at face value.
Key parameters include:
- U-value
- Air permeability
- Watertightness
- Wind resistance
- Solar control
- Acoustic performance
- Condensation resistance
- Glass safety
- Material durability
These figures should always be compared using equivalent testing standards and matching product configurations.
5. Customization and OEM Capability
This is often where a traditional branded supplier and an OEM-oriented manufacturer part ways.
For importers and distributors, the questions worth asking include:
- Are custom dimensions available?
- Can the frame material be changed?
- Can glazing specifications be customized?
- Are RAL colors available?
- Is private-label production possible?
- Can packaging carry the buyer's brand?
- Can technical drawings be supplied?
- Is product development support available?
For companies building out their own roof-window product line, these questions can matter more than brand recognition.
6. Production Capacity and Lead Time
Even a technically strong manufacturer becomes a poor fit if it can't maintain consistent supply.
Buyers should evaluate:
- Factory capacity
- Production automation
- Minimum order quantity
- Sample lead time
- Mass-production lead time
- Packaging standards
- Export experience
- Shipping options
- Spare-parts availability
A dependable supply chain matters most for distributors juggling consistent stock across several markets at once.
7. Certification and Quality Control
Before placing a large order, buyers should request the relevant technical documentation up front.
Depending on the destination market, this can include:
- CE-related documentation
- Product test reports
- Thermal-performance data
- Air and water testing
- Wind-load testing
- Quality-management certifications
- Material certifications
- Warranty terms
The exact requirements will vary by country, building code, and intended application.

Which Dachfenster Hersteller Is Right for Your Project?
No single roof-window manufacturer fits every procurement need equally well.
VELUX
Makes sense when brand recognition, wide product availability, and an established global ecosystem top the priority list.
Roto
Particularly worth considering for buyers after German engineering and technically developed roof-window systems.
FAKRO
Stands out thanks to its broad product range and international manufacturing footprint.
Keylite
Carries the most weight for professional installation markets in the UK and Ireland.
DAKEA
Appeals to buyers chasing the right balance between product quality and cost.
RoofLITE+
Suits buyers looking for practical, no-frills European roof-window solutions.
LAMILUX
Becomes more relevant once the requirement shifts toward larger daylighting or rooflight systems rather than conventional residential roof windows.
KUREDA
Offers a distinctive option for replacement, repair, and customized roof-window work.
LiDEKO
Best suited to projects that need large-format sliding roof windows and architectural customization.
AUROLUX
For distributors, importers, and building-material companies after OEM/ODM flexibility, AUROLUX deserves a closer look. Its portfolio spans both pitched and flat roof applications, and its manufacturing model is built to support customized specifications alongside international B2B supply.
Selecting a Dachfenster Hersteller ultimately comes down to matching a manufacturer's strengths with the actual demands of the project, not simply picking the most familiar name on the market. Established European brands such as VELUX, Roto, and FAKRO offer decades of engineering history, broad product ecosystems, and dependable international distribution — a natural fit for projects where brand trust and product availability carry the most weight. Specialists like Keylite, DAKEA, and RoofLITE+ serve professional installers and residential builders with practical, installation-ready product lines, while LAMILUX and LiDEKO occupy more specialized ground, focused on large-scale daylighting systems and oversized architectural glazing respectively. KUREDA, meanwhile, addresses a need the bigger brands often overlook: replacement, repair, and made-to-measure modernization work.
For buyers operating outside the traditional European retail model — particularly distributors, importers, and companies building their own private-label roof window range — manufacturing flexibility tends to matter more than brand heritage. This is where a manufacturer like AUROLUX stands out, offering OEM/ODM capability, custom specifications, and international B2B supply built around the buyer's own requirements rather than a fixed retail catalogue.
In the end, the right choice depends on weighing manufacturing experience, product range, materials, technical performance, customization capability, production capacity, and certification against the specific requirements of the project at hand. A structured comparison across these factors, rather than reliance on brand recognition alone, is what allows professional buyers to select a Dachfenster Hersteller that will hold up — both technically and commercially — over the long term.
