MinAltan - Den sikre løsning

What MinAltan - Den sikre løsning does

MinAltan A/S, trading as MinAltan - Den sikre løsning, is a Danish full-service balcony company founded in 2008 and headquartered in Frederiksberg, with a production and warehouse facility in Hvidovre. The company designs, manufactures, and installs balcony systems primarily for housing cooperatives (andelsboligforeninger), owner associations (ejerforeninger), real estate companies, and capital funds operating multi-story residential apartment buildings in Greater Copenhagen. Core product lines include hot-dip galvanized steel balconies, ultra-high strength concrete (UHBC) balconies, Spanish balconies, French balconies, and roof balconies, complemented by balcony doors, stairs, windows, and radiators as add-on modules, all delivered under totalentreprise (general contractor) contracts covering consultation, municipal permit handling, manufacturing, and installation. The company differentiates technically through hidden bolt assemblies, Cradle to Cradle Bronze certified material selection, and a UHBC concrete system that uses roughly 50% less material and emits about 25% less CO2 per square meter than standard concrete.

The business operates a quote-based pricing model that is not publicly disclosed, with volume discounts for projects exceeding 30 balconies and additional discounts above 50. Sales are conducted directly through the Frederiksberg showroom and on-site consultations by a team of five sales consultants and a Key Account Manager, supported by Trustpilot reviews, showroom events, and free 3D drawings used as a visual sales tool for resident decision-making. The firm holds Cradle to Cradle Bronze certification (2023) and has been a UN Global Compact member since 2021, and maintains sustainability partnerships with Jensen Metal (steel production, Latvia), Gamle Mursten (brick recycling), P. Fournaise (glass recycling), and Isover (insulation).

In September 2025 Grundtvig Invest A/S took full ownership by buying out the founder, injected an additional 10 million DKK into the business, and appointed Kurt Vahlun Sørensen as CEO in November 2025 following a period of losses, staff reductions, and cost restructuring. As of April 2026, the company reported that approximately 90% of expected 2026/27 revenue had already been sold, representing roughly 22% growth versus the prior financial year, with a target of returning to profitability in 2026/27.

Core offering

MinAltan designs, manufactures, and installs balcony solutions — primarily steel and concrete balconies — for multi-story residential buildings in Greater Copenhagen. Operating as a full-service general contractor (totalentreprise), the company handles every phase from initial consultation and design through municipal permit acquisition, in-house manufacturing (using Cradle to Cradle certified materials at the Hvidovre production facility), and on-site installation by trained assembly teams. Core customers are housing cooperatives (andelsforeninger) and owner associations (ejerforeninger), with complementary offerings of balcony doors, stairs, energy-optimized windows, and radiators bundled into renovation projects.

Products and services

• Stålaltaner (Steel Balconies) Hot-dip galvanized steel balconies with an elegant, classic design without visible bolt connections. Steel is 3 times stronger than aluminum, providing durability and low maintenance. Designed for Danish housing cooperatives and owner associations adding balconies to multi-story residential buildings.
• Betonaltaner (Concrete Balconies) High-strength concrete balconies using Ultra High Strength Concrete (UHPC) with 50% less material and 25% lower CO2 emissions per square meter compared to standard concrete. Classic design complements older buildings with stucco or national-romantic style architecture.
• Spanske altaner (Spanish Balconies) Spanish-style balconies similar to French balconies but with a smaller overhang, allowing space for potted plants or decorative items. Suitable for buildings where a full projecting balcony is not feasible but an outdoor accent is desired.
• Franske altaner (French Balconies) Elegant solution consisting of a door that opens inward with a safety railing on the outside, creating a feeling of being outdoors while remaining indoors. Designed for buildings where space constraints prevent a projecting balcony.
• Tagaltaner (Roof Balconies) Balconies partially built into the roof, either projecting over or set back from the facade. Constructed with hot-dip galvanized steel, zinc roofing, and Ibond panel undersides. Designed for buildings with pitched roofs where a traditional facade balcony is not possible.
• Altandøre (Balcony Doors) Balcony doors designed to integrate seamlessly with balcony installations, with new window sills matching existing ones. Offered as part of total renovation projects alongside balcony construction.
• Altantrapper (Balcony Stairs) Stairs designed for balcony access as part of complete balcony solutions, manufactured by MinAltan to integrate with installed balcony systems.
• Vinduer (Windows) Energy-optimized windows offered as part of total renovation projects, replacing windows simultaneously with balcony installations to improve building energy performance.
• Radiatorer (Radiators) Radiators offered as complementary products to balcony and window replacement projects, typically bundled into total renovation offerings.
