SIAS

What SIAS does

SIAS SA (also branded "Specialised Window Applications") is a privately held Greek company headquartered in Glyka Nera, Athens, that operates as the exclusive Greek distributor and installer of premium European window and façade system brands. Its core offering spans three primary technology families: Vitrocsa slim aluminium profiles with concealed-rail sliding systems (including the patented Invisible Frame, PCT/IB012/050480), Secco Sistemi steel window frames (including the Compasso d'Oro ADI-winning OS2 profile system), and Carminati Serramenti minimal wooden frames, complemented by five additional European wooden window manufacturers covering oak, fir, walnut, meranti, iroko, and chestnut. The portfolio has expanded beyond exterior glazing into contemporary ceiling-height interior doors (hinged, sliding, pivot; up to 3,400 mm) and classic interior doors, allowing the company to supply both categories from a single source. SIAS generates revenue through project-specific, quote-based sales of imported systems combined with in-house architectural detailing, certified installation, and after-sales maintenance; products carry CE, DIN, British Standard, and ISO certifications.

SIAS goes to market exclusively via direct enterprise sales through its Athens showroom and an in-house design department that collaborates with project architects from the specification stage. Customers are architects, developers, and owners of high-end residential and hospitality projects throughout Greece (e.g., projects on Mykonos, Crete, Zakynthos, Porto Heli, Antiparos, Kerkyra, Attiki), with no retail or e-commerce channel. Supporting marketing activities include a substantive editorial blog (blog.sias.gr), active social channels (Instagram, Facebook, Twitter, Pinterest, Vimeo), an email newsletter, and sponsorships of Greek architectural events such as Open House Athens, the ESW Interior Design Conference, and the Greek Young Architects Biennial.

The company has been operating for approximately twenty years, has completed over 1,400 projects, and occupies 4,500 m² of privately owned facilities. It employs 11-50 staff on a direct-sales and own-installation model. Ownership is private and concentrated (founder/owner-operated, with no disclosed institutional investors), there are no subsidiaries, no funding rounds on record, and no M&A activity. Geographic operations are confined to Greece, with no published expansion outside the country.

• Cortizo: Spanish aluminium systems manufacturer offering premium window and door profiles with European distribution. Targets the same architect-driven luxury renovation and new-build segment as SIAS, with growing presence across Southern Europe.
• Aluprof: Polish aluminium window, door and facade systems manufacturer with European distribution. Markets high-end slim aluminium profiles comparable to Vitrocsa into architect-led residential and commercial projects, including Greece.
• Reynaers Aluminium: Belgian premium architectural aluminium window, door and facade systems manufacturer with a multi-country distributor model closely parallel to SIAS's exclusive-distribution approach. Competes head-on in the same Greek high-end residential and hospitality specification market that SIAS serves.
• Technal: French architectural aluminium systems brand (Hydro group) with premium sliding and minimal-frame solutions and an international distributor network. Directly competes for the slim-profile, architect-specified residential and hospitality projects SIAS targets.

• ETEM Group: Bulgarian aluminium extrusion and systems manufacturer serving Southeastern European architectural markets, including Greece. Competes for premium residential and commercial projects in geographies overlapping with SIAS.

Others

Emerging players
