What AJM okna-vrata-sencila d.o.o does

AJM okna-vrata-senčila d.o.o. is a Slovenian manufacturer of building joinery founded in 1990 by Marija Ajlec as a small family workshop in the Kozjak area near Maribor, now headquartered in Pesnica pri Mariboru with an ISO 9001-certified (since 1997) and ISO 14001-certified production facility. The company designs and produces windows, balcony doors, sliding systems, entrance doors, and shading systems across five material lines (PVC, PVC-ALU, wood, wood-ALU, aluminium) plus a frameless Zero Sash architectural line and a proprietary I.Access smart home platform for motorized blinds, electric door locks, ekey fingerprint readers, and Somfy/Hero motor integrations. Product technology spans standard glazing (Ug=1.1 W/m²K, Rw=32 dB, up to 51 dB available) through passive-house-grade Pasiv+ lines, with RAL-certified mounting systems for energy-efficient installation.

AJM serves primarily residential homeowners (new-construction and renovation) across Slovenia via 7 owned sales showrooms (Pesnica, Ljubljana, Kranj, Murska Sobota, Celje, Koper, Nova Gorica) supplemented by field sales consultants offering free on-site measurement and quote preparation, with secondary commercial/hospitality accounts (Hotel Maribor, Terme Bains de Lavey, premium wineries in the Brda region). The business model is project-based one-time product sale plus installation services (classical and RAL mounting) with multi-option payment plans (60/40 split, 100% upfront with 5% discount, NLB Green Partner Credit, EKO fund) and recurring maintenance services at €65 per service hour. Distribution extends internationally through dedicated country websites for Austria, Germany, and Switzerland.

In 2024-2025, Swedish group Inwido acquired 70% of AJM, integrating it as one of approximately 38 business units in a European platform of ~5,200 employees and SEK 8.8 billion (≈€803M) revenue; the Ajlec family retained 30%, and Director Trivo Krempl (in role since 2013) continues to lead the company. AJM's market position is reinforced by long-standing certifications (Golden Quality Sign in Construction since 1997, Golden Environmental Sign 2025) and a track record of German Innovation Award, German Design Award, and Big See Product Design Award recognition.

Direct peers

• Veka AG: German PVC profile manufacturer for windows and doors, supplying fabricators across Europe. Comparable to AJM in PVC fenestration technology and European market footprint, particularly in DACH where AJM is expanding.
• Gealan: European PVC window and door profile systems maker (part of VEKA Group). Comparable to AJM in PVC profiles, fabrication model, and Central European customer base of window manufacturers.
• Salamander Industrie-Produkte: German manufacturer of PVC window and door systems, primarily serving European fabricators and dealers. Directly comparable to AJM's PVC window line offering and serves similar European mid-market and premium residential segments.
• Kömmerling: European PVC window profile brand (part of Profine Group), serving fabricators across Europe. Comparable to AJM in PVC fenestration technology and the premium residential market segment where AJM's Energeto/Pasiv lines compete.
• Drutex: One of Europe's largest window and door manufacturers, headquartered in Poland, with PVC, wood-ALU, and aluminium product lines. Comparable to AJM in vertical integration, multi-material portfolio, and Central European market positioning.
• Inwido: Parent company and direct peer; Inwido is Europe's leading windows and doors group (38 business units, ~5,200 employees, ~€803M 2024 revenue). Highly comparable because Inwido's broader business unit portfolio spans the same window and door manufacturing categories that AJM operates in, including PVC, wood, and aluminium.
• Internorm: Austrian premium window and door manufacturer serving DACH and Central Europe. Directly comparable to AJM in product range (PVC, wood-ALU, ALU systems), customer segments (residential and commercial), and geography (overlap in Austria and Slovenia).
• Aluplast: German PVC window and door profile manufacturer serving European fabricators. Directly comparable to AJM in the PVC window segment, particularly the Energeto and high-insulation lines that compete with AJM's Performance and Pasiv ranges.

Broad incumbents

• Schüco: German global player in aluminium and PVC-U window, door, and façade systems. Comparable to AJM in premium aluminium fenestration and architectural commercial projects, but operates at much larger scale across global markets.
• REHAU Windows & Doors: Global polymer-based solutions provider with a strong windows and doors division (uPVC profile systems). Comparable to AJM in fenestration products and DACH market presence, though REHAU is significantly larger and offers broader industrial and building solutions beyond windows.
