Only what is printed in the manufacturer's catalogue.
One 2024 report: the production partner’s 70 series tilt & turn window, class CW-PG50, specimen 1200 × 1800 mm, design pressure ±2400 Pa, water 720 Pa
Standard: AAMA/WDMA/CSA 101/I.S.2/A440-17 (NAFS). The catalogue prints only a thumbnail of the report; the number is not reliably legible and the full report has been requested. The catalogue has no reports for other series.
Air, water, wind, thermal and acoustic classes as printed in the catalogue, with the scales of sheet 27
Classes are printed in the catalogue together with the scales, so each class maps to a defined range of the physical value. The catalogue gives no classes for 110 OUT, 100 SL and the winter garden. We hold no test reports behind the GB classes.
The production partner’s installation teams are prize-winners of the WPL (WINDOOR) professional league
The certificates appear in the catalogue as thumbnails; year, league and placing for each will follow once the originals arrive.

LLP details for the contract and supplier registration.
System datasheet, GB classes with values and batch documents.
GB classes are a Chinese scale: the higher the number, the better, and each property has its own ceiling.
The manufacturer declares the class in its catalogue, so next to it we always print the physical value — in pascals, watts or decibels.
For project calculations we use the value, not the class number: a number reads the same in any system of standards.
