Discover our history
Isoltema | Keep it dry, keep it safe
Isoltema was set up in the early-Eighties, in Gambettola as a small manufacturer of self-adhesive products for the building trade. In 1992 it became Isoltema S.p.A. and started exporting its products worldwide. After nearly a decade, the company achieved a production output of up to 2.5 million square metres of adhesive rolls and membranes sold worldwide. The dynamic development of the company led to the opening of a distribution office in the United States of America under the name of TTI. This was one of the factors of the company’s success on the US market, especially with Ekobit, a bituminous-based product. In 2006 the company invested in the construction of a new high-tech production facility in Longiano, thanks to which it achieved the ambitious goal of 10 million square metres of membranes and bituminous tapes. At the same time, Isoltema started manufacturing Butyl Sealants and in 2010 went into partnership with the Spanish distributor A&S. Just two years later came the strategic turning point for Isoltema with the purchase of the French company Olin, specialized in the production and sale of extruded tapes, thanks to which it completed its butyl range. This opportunity enabled the Isoltema Group to further specialize in the production of butyl products – cut tapes under the Isoltema brand and extruded tapes and compounds under the Olin brand. In 2015, the Die Cut machine was purchased thanks to which products can be made in various shapes to cater to customer requirements. The company has also improved its production capacity as regards butyl sold in drums and continues to invest in order to provide customized compounds able to satisfy the technical requirements of its customers.  
Olin | La solution d’étanchéité
Olin was established in the late-Fifties as a company specialized in the production of linseed-oil based adhesives.
Two decades passed before the company started making top-quality self-adhesive butyl products and made a name for itself above all on the French market. In the early-Nineties, the first butyl sealing tape reinforced with aluminium film was produced and Olin began to assert itself on the global market.
With over thirty years of experience, Olin invested in new technologies and built a new production plant dedicated to the production of butyl in St. Pierre de Chandieu.
50 years later, we can say that the company has come a long way since those linseed-oil based adhesive days. Backed by its many years of experience in the field of butyl extrusion, in 2012 Olin was acquired by Isoltema and became a member and a technological partner of excellence of the Isoltema Group.
Total Quality.
For the Isoltema Group, Quality is an imperative concept. Every action, process and material must be synonymous with quality.

For its products, the Group uses carefully selected Raw Materials supplied by certified producers which, together with internal controls, ensures that these are of the highest quality and in conformity with the very best industrial standards. All production processes are fully automated and controlled by PLC, to ensure the traceability of each operating phase.

Our products must be suitable for application in any country in the world, in any environmental condition, while always complying with the specifications and performances indicated on the technical sheets. For this reason, with the R&D Laboratory inside the Company, a Total Quality Control program has been set up, aimed at monitoring every stage of the production process, from Raw Material to Finished Product, from the normal Ageing Process to Packaging Quality.
The Quality Control System adopted by the Isoltema Group.
Quality Control carries out all the tests required by EN 13707, EN 13969 and EN 13970 standards during and at the end of the Isoltema bituminous membrane production process.
The company’s bituminous membranes are therefore marketed with an EC Declaration of Conformity. Butyl products are also placed on the market with an EC Declaration according to the harmonised EN 13956 standard.
The products of the Isoltema range are tested and certified according to European and international standards depending on the sector and field of application.
For all butyl and bituminous products, Isoltema holds assessment of emissions of volatile organic compounds (VOCs) made by the eco-INSTITUTE according to SINTEF ISO 16000-6 standards. Some products of the Isoltema range have undergone tests to determine fire resistance according to UNI EN 13501 and UNI EN ISO 11925-2. Other products, mainly intended for the building trade, have been tested to determine water vapour permeability in accordance with UNI EN 1931 and water tightness in accordance with UNI EN 1928. What is more, for some of its bituminous membranes, Isoltema holds Radon Barrier certification issued by SP Swedish National Testing & Research Institute and Methane Barrier certification according to the CSI Method.
In order to carry out internal Quality Controls aimed at further guaranteeing the high quality standards of the product, a sample of compound is taken for each production batch and subjected to the R&D Laboratory controls based on consolidated international standards. Our laboratory also carries out further dedicated tests on products manufactured purposely for specific applications.
For each production batch, samples of the finished product are also kept together with relative quality test results, which allow product traceability over time: the data acquired from the Quality Control tests are then filed and stored in a double archive, electronic and paper.
As a responsible company, we design our products to be sustainable and to provide long-term satisfaction.

Ageing Checks
To perform Ageing Checks, a roll of material is sampled monthly. On the sampled material, all scheduled tests are carried out periodically  in order to monitor the normal behaviour of the compound over time; according to Isoltema standards, this must maintain adequate adhesive characteristics for over 10 years.

Packaging Checks
Further random checks are performed on the packaged product. The aim of these checks is to ensure packaging complies with customer requirements and promptly implement improvement measures to ensure best possible packaging characteristics.
