What İZODER Official does

İZODER Isı Su Ses ve Yangın Yalıtımcıları Derneği is a Turkish non-profit trade association founded in June 1993, headquartered in Ümraniye, Istanbul, that serves as the central industry body for heat, water, sound, and fire insulation material manufacturers, sellers, and applicators in Turkey. With 100+ member companies and a 15-person staff, the association operates through six regional representation offices (Central Istanbul, Black Sea, Central Anatolia, Aegean, Mediterranean, East and Southeast Anatolia) and provides industry representation, technical standards development, professional certification via the İKOS program, regional training seminars, and the İZODERGİ quarterly publication (now at issue 179). Its core offerings include the TS 825 Hesap Programı (free thermal insulation calculation tool), technical implementation guides co-developed with the Ministry of Environment, Urbanization and Climate Change and Istanbul Technical University, and an online directory of certified applicators for end consumers.

The association's revenue model is membership-driven, with annual dues tiered by member revenue: producer members pay 125,000–350,000 TL (Groups A–F, 5–14 representatives each) and seller/applicator members pay 25,000–75,000 TL (Groups A–C), supplemented by one-time entry fees of 50,000 TL and 10,500 TL respectively. The go-to-market is community-led, leveraging the İZODERGİ magazine, website, e-bulletins, YouTube channel, trade show participation, and mainstream Turkish TV appearances. İZODER holds formal technical cooperation agreements with the Ministry of Environment, Urbanization and Climate Change, has research partnerships with İTÜ, and was selected to a World Bank/EU-funded consortium on energy efficiency in 2025.

Strategically, İZODER plays a regulatory influence role: it contributed to the April 2025 update of the TS 825:2024 thermal insulation standard (mandatory for buildings over 2,000 m² under Near-Zero Energy Building rules), published implementation guides for water insulation and noise protection regulations, and conducted the 'Effects of Doweling Application on Building Statics' research with İTÜ supported by 14 member companies. The organization is governed by an elected Board of Directors; Atalay Özdayı (CEO of Baumit Türkiye) was elected Chairman of the 16th term in February 2026, succeeding Emrullah Eruslu of the 15th term. A subsidiary, TEBAR A.Ş., supports regional coordination activities.

Expansion highlights4 records

Direct peers

• NAIMA (North American Insulation Manufacturers Association): North American trade association representing insulation manufacturers, directly analogous to İZODER in advocating for industry standards, codes, and energy efficiency policy on behalf of producer members.
• PU Europe: European association for polyurethane insulation producers, a direct peer to İZODER in advocating for a specific insulation material category with a focus on building energy performance standards.
• EURIMA (European Insulation Manufacturers Association): Pan-European trade association for insulation manufacturers, directly comparable to İZODER in mission (industry representation, standards advocacy, energy efficiency promotion) but operating at EU level across multiple national markets.
• EUMEPS (European Manufacturers of Expanded Polystyrene): European association representing EPS insulation manufacturers, comparable to İZODER in serving foam-plastic insulation producers with standards, advocacy, and market development focus.
• Türkiye İMSAD (Türkiye İnşaat Malzemesi Sanayicileri Derneği): Turkish Construction Materials Industry Association, a directly comparable Turkish trade body covering broader construction materials with overlapping member companies. Already a partner of İZODER but could compete for advocacy attention.
• NIA (National Insulation Association): US-based trade association for insulation contractors and distributors, comparable to İZODER as a membership-driven body promoting proper installation, training, and energy efficiency standards in the building insulation sector.

Broad incumbents

• ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers): Global engineering society focused on HVAC&R and building systems, a broader incumbent whose standards work (notably ASHRAE 90.1) overlaps with İZODER's TS 825 thermal insulation standard activities in scope.
• CIBSE (Chartered Institution of Building Services Engineers): UK-based engineering body covering building services (HVAC, lighting, energy) with comparable mission to İZODER in promoting technical standards, training, and certification for the building envelope and MEP disciplines.

Emerging players

• IIBEC (International Institute of Building Enclosure Consultants): International body for building enclosure consultants, an emerging specialized peer that overlaps with İZODER's waterproofing, thermal, and acoustic insulation remit but with a consultant rather than manufacturer focus.

Others

• FIW (Forschungsinstitut für Wärmeschutz e.V.): German research institute for thermal insulation, an adjacent enabling organization that conducts testing and research comparable to İZODER's ITU research collaboration on building envelope performance.
