Construction Products Legislation 2026: What Changes in Romania and the EU

What is the European Construction Products Regulation (CPR)?

Regulation (EU) No 305/2011 — known as the CPR (Construction Products Regulation) — is the European legislation that sets the conditions for placing all construction products on the EU market. It requires manufacturers to draw up a Declaration of Performance (DoP) and to affix the CE marking to their products, windows, doors, PVC and aluminium profiles included.

Romania transposed the CPR through Law 10/1995 on quality in construction and Government Decision 622/2004, updated by Government Decision 765/2016 — the act that also sets the nZEB requirements mandatory since 2021.

What changes in 2026 for construction products?

1. The new CPR 2 regulation comes into force

In 2024 the European Commission adopted Regulation (EU) 2024/3110, which replaces the 2011 CPR and introduces stricter requirements:

The main changes:

• Digital Declarations of Performance (eDoP) — mandatory from 2026, accessible via a QR code on the product
• Digital Product Passport (DPP) — every product will carry a unique European ID with all its technical specifications
• Extended ESG requirements — declaring the product carbon footprint (PCF) and the recycled material content becomes mandatory for selected categories
• Reinforced market surveillance — tighter controls on products imported from outside the EU

2. Standard EN 14351-1 — 2026 update

EN 14351-1:2006+A2:2016 (the standard for external windows and doors) is under revision, with a new version expected in 2026–2027, which will include:

• Updated requirements for air permeability (Class 4 — mandatory for nZEB)
• Improved testing for wind resistance (≥ Class C3)
• New requirements for burglary resistance (RC2 for residential buildings)

3. nZEB requirements remain mandatory and get stricter

Since 2021, every new building in Romania must meet the nZEB standard (Nearly Zero Energy Building), which requires:

• Uw ≤ 1.00 W/(m²K) for windows in Climate Zone II, which covers Bucharest
• Primary energy consumption ≤ 100 kWh/m²/year
• At least 10% of energy from renewable sources

From 2026, local authorities (ISC — the State Construction Inspectorate) are stepping up checks at project handover, with mandatory verification of the technical documents for the windows and doors installed.

4. CE marking — what you need to check

Any window or door sold legally in Romania and the EU must carry the CE marking, showing:

• The standard number (EN 14351-1)
• The declared values: air permeability, water tightness, wind resistance, Uw
• A reference to the Declaration of Performance (DoP)

What this means for you as a buyer:

Always ask for the product DoP and the test certificate (IFT Rosenheim, TÜV, CSTB) before signing the contract. A serious supplier provides these documents without being asked.

What certifications do Neofort BIZ products hold?

Prohibited practices and risks for buyers

Watch out for:

• Windows with no CE marking, or with a false CE marking (no verifiable DoP number)
• PVC profiles without an IFT or TÜV certificate — the declared Uw may be wrong
• Suppliers who cannot produce a DoP on request
• Non-EU imported profiles that have not been tested to European standards

Legal consequences: installing non-compliant windows in a building that required a construction permit can lead to the works being rejected by the ISC, with remediation at the investor’s expense.

FAQ — Construction product legislation 2026

What is a Declaration of Performance (DoP)?

The DoP is the mandatory document issued by the manufacturer declaring the tested technical values of the product (Uw, air permeability, wind resistance and so on) under EN 14351-1. Without a DoP, the product cannot legally be sold in the EU.

What does CE marking mean on a window?

CE marking confirms that the window has been tested and meets the requirements of the European standard EN 14351-1. It is not a quality label but a mandatory declaration of conformity for sale within the EU.

Is nZEB certification mandatory for renovations?

Yes, for renovations under a construction permit that affect more than 25% of the envelope area. If you replace all the windows of a block or a house, the project has to reach nZEB performance.

What changes concretely in 2026 compared with 2025?

The main points: digital DoPs with QR codes become the norm, ISC checks at handover intensify, and the new CPR 2 enters its transition period — manufacturers have three years to comply fully.

How do I check whether the windows I bought are compliant?

Ask for the DoP number on the product’s CE label and verify it on the manufacturer’s site or with the certification body. At Neofort BIZ, all documents are available on request.
