What Sherwood Windows does

Sherwood Windows Limited is a privately held Canadian manufacturer founded in 1953 that designs, fabricates, and distributes custom security and specialty fenestration products for institutional and architectural projects across North America. Its portfolio is organized around three product families: the Detention Series, led by the DSW 6260 fully thermally broken stainless steel and aluminum security window and screen system; the Mental Health Series, comprising the MHW 6200 and MHW 6300 thermally broken aluminum behavioral health windows with anti-ligature geometry, flush interior surfaces, and patient-controlled ventilation; and a Security Sash line (SS 5100, 6100, 6200) targeting mental health facility retrofits and new builds. Underlying technology centers on engineered aluminum and stainless steel frame construction, thermal break fabrication techniques, and adherence to a broad set of performance certifications including ASTM E330-02, ASTM E331-00, ASTM E283-04, ASTM E547-00, BS6206, NFRC 102, CSA A440.2, and ASTM E90.

The company serves three primary customer verticals: government detention and correctional facilities, mental health and behavioral healthcare providers, and architectural construction projects. Sales are project-based and consultative, with direct engagement of architects, specification writers, contractors, and facility owners; the firm facilitates specifications through CAD drawing requests and CAD-driven design collaboration via its website. Sherwood Windows operates from its head office in Toronto, Ontario (37 Iron Street) and a US office in Osprey, Florida (284 Sugar Mill Drive), with a workforce of 11-50 employees. Marketing is conducted through its corporate website, LinkedIn presence, and participation in industry events such as the American Jail Association annual conference and jail expo. Pricing is quote-based and project-specific, with no disclosed recurring or subscription revenue model. The company appears to be independently owned with no evidence of external institutional investment, private equity backing, or parent company ownership.

• ASSA ABLOY (Americas): ASSA ABLOY is the global leader in door openings and access solutions, including detention/security door products serving correctional facilities.

Comparable to Sherwood's combined detention, behavioral health, and architectural window offering.
• Hope's Windows: Hope's Windows manufactures solid steel and hot-rolled steel profile windows used in detention, blast-resistant, and high-security architectural applications. It is a direct peer to Sherwood given its overlapping specialty fenestration focus on correctional and high-security projects.
