Valmieras Stikla Skiedra

What Valmieras Stikla Skiedra does

Valmieras Stikla Skiedra (operating as Valmiera Glass Group) is a Latvia-headquartered, vertically integrated glass fibre manufacturer producing fibreglass products from three glass chemistries — E-glass (600°C temperature resistance), HR-glass (800°C), and SiO2-glass (1000+°C) — with the group claiming to be the only firm worldwide offering this full integrated range for the thermal insulation market up to 1250°C. The company serves B2B enterprise customers across construction, thermal insulation, aviation, composites, and machine building verticals, with manufacturing operations at its Valmiera, Latvia headquarters (Cempu iela 13) and through wholly-owned UK subsidiary VALMIERA GLASS UK Ltd. in Sherborne, Dorset. The group employs 1,100-1,200 people and exports to more than 45 countries, supported by a direct enterprise field-sales model organized by both geography and product segment, with dedicated sales managers covering Europe, North America, Middle East, and Asia.

The group monetizes through direct manufacturing and sale of glass fibre products used for further processing into technical textiles, insulation materials, and composite materials, as well as finished goods in building and mechanical engineering applications. Revenue in 2024 reached 120.09 million EUR with EBITDA of 11.41 million EUR (9.5% margin) and EBIT of 1.93 million EUR (1.6% margin). Since delisting from Nasdaq Riga in March 2021, the company has been majority-owned by Luxembourg-registered Duke I S.à r.l. (97.18% stake) and has executed a multi-phase share-capital restructuring through 2023 to restore equity structure and EU funding eligibility. R&D activity is anchored on a €5.59M EU co-financed project (2023-2026) developing new synthetic polymer sizing compositions, alongside complementary research on synthetic gypsum for building products in partnership with SIA VMKC and Riga Technical University. Operations are certified to ISO 9001:2015 (quality), ISO 50001 (energy management), and ISO 14001:2004 (environmental management).

Broad incumbents

• Johns Manville: US-based insulation and engineered products manufacturer (Berkshire Hathaway subsidiary) producing fibreglass and other insulation materials for buildings, industrial applications and HVAC systems. Broad incumbent with overlapping insulation-product offering into European construction and industrial segments.
• PPG Industries: US-headquartered global coatings and specialty materials company producing glass-fibre reinforcement products used in automotive, construction and industrial applications. Broad incumbent with glass-fibre reinforcement as part of a wider coatings and materials portfolio.
• Nippon Electric Glass: Japan-based global glass manufacturer producing glass fibres and yarns for electronics, construction reinforcement and industrial applications, alongside larger display, optical and architectural glass businesses. A broader incumbent with overlapping capabilities in glass fibre reinforcement as part of a wider glass portfolio.
