CE marking

The page said all Batty Joinery windows and external doorsets carry the CE mark under the Construction Products Regulations, with product data in a Declaration of Performance.

Declarations named on the page

Casement windows:

• Thermal performance below U-value 1.6
• Thermal performance below U-value 1.4
• Thermal performance below U-value 2.0

Sliding sash:

Each item on the original page linked to a declaration PDF. Those files were not saved into this copy. The archive also holds small files under /_inc/uploads/ with names such as Window_Uvalue_1.4.pdf from February 2025; they are only about 8 KB, so they may not be the full declarations.
