CPV 4532 – Insulation Works

What does CPV 4532 cover?

CPV 4532 covers all thermal, acoustic and fire protection insulation works carried out on buildings and technical installations. In building construction, this principally covers the application of external thermal composite systems (ETICS/WDVS) to facades, the thermal insulation of flat and pitched roofs, insulation of floor slabs and cellar ceilings, as well as interior insulation systems. In the technical building services field, pipe insulation for heating, cooling, drinking water and ventilation ducts is equally relevant.

In the context of public procurement, insulation works are frequently tendered as standalone specialist lots following completion of the shell construction. Energy efficiency requirements arising from the Building Energy Act (GEG) and the EU Energy Performance of Buildings Directive (EPBD) are increasingly shaping the technical specifications. The quality of insulation works is critical for achieving the energy performance targets set out in building contracts, and deficiencies are difficult and costly to remedy after completion.

Public contracting authorities include state building authorities, municipal housing companies, school building authorities and facility management departments. Refurbishment projects for existing building stock – particularly schools, residential blocks and public administrative buildings – represent a major share of insulation tenders. Further information on the CPV system is available from the European Commission (SIMAP) and in Regulation (EC) No 213/2008.

Examples of Tenders with CPV 4532

• Facade insulation for social housing complex: A municipal housing company tenders the application of an external thermal composite system to 12 residential blocks (total facade area approx. 18,000 m²), including substrate preparation, attachment of mineral wool insulation boards (WLG 035, 180 mm), primer, reinforced base coat and silicone resin render system, with scaffold erection and temporary weatherproofing.
• Flat roof insulation for school refurbishment: A school building authority awards the insulation renewal of five school flat roofs, covering removal of existing insulation, vapour barrier installation, application of PIR insulation (200 mm, WLG 022) and a new two-layer bituminous waterproofing membrane.
• Pipe insulation for district heating network in administrative centre: A municipality tenders the thermal insulation of all heating and cooling pipework in a new administrative centre, covering pre-insulated pipe sections, flexible foam insulation with vapour barrier for cooling circuits, and fire-rated insulation at wall and floor penetrations.

Current tenders with CPV 4532 are published on TED (Tenders Electronic Daily) and on national procurement platforms.

Who is CPV 4531 relevant for?

Public Contracting Authorities

State building authorities, municipal housing companies, school building authorities and energy agencies are the main contracting authorities for insulation tenders. They award insulation works principally in the context of energetic refurbishment programmes, new construction projects and the renovation of public building stock. Compliance with current energy standards (GEG, KfW efficiency house levels) and the use of certified insulation systems are standard requirements.

Companies and Bidders

Specialist insulation contractors and plastering firms with proven experience in ETICS systems are the primary bidders. In addition to references for comparable insulation projects, evidence of system-specific certifications (e.g. WDVS installer qualification from system manufacturers), qualified site management and quality assurance documentation are expected. For fire-rated insulation works, additional classification evidence is required.

Information on eligibility requirements and procurement procedures is provided by the Federal Ministry for Economic Affairs and Climate Action (BMWK).
