5-Step CE & Passive House Documentation Process

From thermal review to CE documentation, with a structured workflow for European project approval.

01

Requirements review

Review project climate zone, opening sizes, target standard, drawings, and local approval route.

Week 1
02

Test specimen production

Build full-size specimens to the nominated configuration, glazing, hardware, and performance target.

Week 2–4
03

Third-party laboratory testing

Coordinate the applicable accredited laboratory tests and record the performance data required for submission.

Week 5–8
04

Engineering document submission

Prepare calculations, drawings, installation details, declarations, and supporting test documentation.

Week 9–10
05

Local documentation issuance

Support the nominated local authority, notified body, or certification route through final documentation.

Week 11–12

Thermal targets, installation details, and CE documentation are confirmed against the project specification and nominated market.

Can you provide CE documentation for project-specific configurations?

Yes. We review the profile, glazing, hardware, dimensions, and installation details before preparing the applicable technical documentation.

What is the thermal target for the European systems?

The range is engineered around Uw≤0.8 W/(m²K), subject to the selected configuration, dimensions, glass, spacer, and installation conditions.

Do you provide ITT specimens?

Project-specific specimens and supporting calculations can be prepared for the nominated notified-body or laboratory route.

Can the CE documentation be issued under our company name?

Documentation and declarations are coordinated through the applicable legal manufacturer and project certification route.
