ISA Spa

What ISA Spa does

ISA Spa is an Italian mechanical engineering company founded in 1971, headquartered in Calcinelli (Pesaro e Urbino province), that designs and manufactures building envelope systems for the construction sector. Its core offering comprises three integrated product lines: Involucri Edilizi (Building Envelopes) providing thermal, acoustic, and weather insulation; Facciate Continue (Curtain Walls) consisting of non-structural aluminum and glass exterior wall systems for large-scale commercial and office buildings; and Infissi Alluminio (Aluminum Fixtures) covering windows, doors, and window frames for architectural applications. The company holds the mandatory Attestazione SOA certification, obtained in 2001, which is required for participation in Italian public works contracts above specified thresholds. Paid-in share capital stands at €1,032,000 and headcount is reported in the 101-250 range.

ISA Spa serves commercial and residential developers, corporate real estate and institutional clients across Italy and the United Kingdom, with offices in Rome and Milan supplementing its Calcinelli production facility, plus a wholly-owned UK subsidiary (ISA UK ENVELOPE SOLUTIONS LTD) based in London. Revenue is generated through project-based construction contracts — direct, one-time engagements with developers, general contractors, and property owners for new construction and renovation projects — rather than through recurring subscription or licensing arrangements. Named enterprise clients include Symbiosis District (Milan), Corso Como Place (Milan), Prysmian Group headquarters (Milan), and Università degli Studi Roma Tre (Rome). The company operates a horizontal segmentation approach, combining design, manufacturing, and turnkey installation capabilities within a single unified offering.
