Jilleba Leiden

Jilleba Leiden — trading as Jilleba Glas in Lood / Glashandel — is a Dutch family-run glass specialist based in Leiden. According to its own company history, it has supplied various types of glass for around 85 years, tracing its origins to 1938. The firm describes itself as a specialist in glass types and glass services for the Leiden region, combining a traditional glazing workshop with a modern glass trade. The company's oldest specialisation is stained glass (glas in lood). Its certified glaziers restore existing stained-glass windows or make new ones, and the firm also produces its own monumental glass. A second core activity is monumental glazing: restoring the glazing of historic buildings according to authentic methods while improving sustainability with insulating glass. Jilleba states that it has been making stained glass between insulating glass for 25 years, a technique that protects historic leaded windows while adding thermal performance. Alongside heritage work, Jilleba supplies hard glass and modern insulation products. It is a dealer of FINEO vacuum glass, which it markets as offering the insulating performance of triple glazing at the thickness of single glazing — a proposition aimed at monumental and older buildings where thick glazing packages are difficult to fit. The company works with custom sizes and special colours and takes on both private design projects and larger office or institutional commissions. Jilleba operates from a showroom at Amphoraweg 5 in Leiden. Following a reorganisation, the company stopped private retail sales from 1 June 2020 and now focuses on business-to-business (B2B) sales. Its customer base therefore centres on contractors, architects, monument owners, churches and other professional clients rather than individual consumers. The company presents itself as a family business with more than 85 years of experience in stained-glass work and monument restoration, positioning itself at the intersection of craft heritage and energy-efficiency upgrades for historic buildings.

Jilleba Leiden traces its history to 1938, when the family glass business was established in Leiden, in the Dutch province of South Holland. Over the following decades it developed into a regional specialist in glass types and glass services, with stained glass (glas in lood) becoming its oldest specialisation. The company's glaziers restore leaded and stained-glass windows and also produce new ones, and the firm states that it uses monumental glass of its own production. A significant technical development in its history was the introduction of stained glass set between insulating glass, a method the company says it has been applying for 25 years. This technique allows historic leaded windows to be preserved while improving the thermal performance of the building — an important capability in the Netherlands, where many monuments and older buildings are subject to preservation rules but also to modern energy-efficiency expectations. Alongside restoration, Jilleba built a glass trade business supplying hard glass and other glass types, and it later became a dealer of FINEO vacuum glass, marketed as combining the insulating power of triple glazing with the thickness of single glazing. The company operates a showroom at Amphoraweg 5 in Leiden. A major turning point came in 2020. Citing a reorganisation, Jilleba announced that from 1 June 2020 it would stop private (consumer) sales and concentrate on business-to-business sales. This shifted its focus decisively toward professional clients such as contractors, architects, monument owners and institutions. By the early 2020s the company described itself as having more than 85 years of experience in stained-glass work and monument restoration, and it continues to present itself as a family business rooted in Leiden.
