Lizmontagens – Empresa de Montagens Termo-Industriais, S.A. (NIF 500809232) is a Lisbon-based industrial-furnace contractor that grew out of the installation teams of Cerâmica do Liz in 1978 and is now part of the LTT Group, which it describes as 37 companies and more than 10,000 professionals. It has had a Norwegian branch (NUF 919037687) since June 2017, VAT-registered since July 2023, and in July 2025 it registered in Sweden as a foreign legal entity approved for F-tax.
Lizmontagens dates its history to 1978, when the installation teams of Cerâmica do Liz were brought together in an independent company. In 1998 it made its first direct investment abroad, in France, which it says deepened its glass-industry know-how and laid the base for expansion into Central and Eastern Europe. It describes itself today as a recognised leader in container and flat-glass furnaces, with a strong presence in steel, energy, incineration, petrochemicals and lime, and offers turnkey glass-to-glass projects, furnace construction, supply of materials and metal structures, furnace demolition, special hot repairs, design and engineering, and industrial chimneys. Its headquarters are in the Central Office building at Avenida D. João II 45 in Lisbon — Vida Imobiliária reported the move in October 2021, under the name Lizmontagens Thermal Technologies — with an engineering department in Marinha Grande, and it is a member of the LTT Group, which it describes as a global network of 37 companies and more than 10,000 specialists.
The Norwegian branch, LIZMONTAGENS - EMPRESA DE MONTAGENS TERMO-INDUSTRIAIS S.A. (NUF, org. no. 919037687), has been in the Brønnøysund register since 14 June 2017, classified under installation of industrial machinery and equipment (NACE 33.200), with a registered activity of assembling and maintaining industrial chimneys and furnace constructions; it was entered in the Norwegian VAT register on 31 July 2023, and the register still gives its business address as Avenida Almirante Gago Coutinho 56 in Lisbon. In Sweden, allabolag.se lists the company under org. no. 502088-0620 as a foreign legal entity registered on 11 July 2025 in industry code 33200 (installation of industrial machinery and equipment), registered for F-tax but not for VAT or as an employer, with no employees on record and a postal address at Avenida D. João II 45. NorthSouth HQ found no published Nordic project references from the company.
Glass, metals and incineration plants depend on furnaces that must be periodically rebuilt or repaired by specialist crews, and Lizmontagens has the oldest Norwegian registration of the three Portuguese refractory contractors NorthSouth HQ has found in the Brønnøysund register, ahead of Globalkiln (2023) and Poweref (2024). Its July 2025 registration in Sweden, with F-tax approval, extends that footprint from Norway into Sweden.
