What we have learned.

Selection guides, drawings and test data from our engineers — the detail behind each product.

Comparison 2026-11-02 How to compare partition cost fairly Comparing partition systems on the price of the wall alone is the most common costing mistake in fit-out. The wall is not the deliverable; the finished, serviced, lettable space is. Read → Selection 2026-11-02 Hospital partitions: acoustics plus services In a hospital the wall has to keep speech private, carry medical gas and data, resist impact and stay cleanable. Those requirements pull in different directions. Read → Selection 2026-11-02 School partitions: what 45 dB actually means A single number hides the frequency detail that decides whether a classroom is usable. What matters in a school is speech, and speech lives in a narrow band. Read → Selection 2026-11-02 Hotel guest-room partitions: five places sound escapes A hotel wall is judged by the guest at 2 a.m., not by the laboratory. In practice the failures cluster in the same five places on every project. Read → Selection 2026-11-02 Retrofit walls at 38 mm When the existing wall has to stay, the new system goes in front of it: 33 mm module, 5 mm clip, levelling bolts, and the services moved into the gap. Read → Comparison 2026-11-02 Clip-on or magnetic: choosing a retrofit wall system Both systems are 38 mm and both are removable. The choice comes down to how often the wall has to be opened, and who will open it. Read → Testing 2026-11-02 Lab Rw vs site performance: where the decibels go A tested wall and a built wall are different objects. The gap between them is not a scandal — it is the sum of flanking, workmanship and penetration details. Read → Testing 2026-11-02 Choosing boards under fire codes A1, B1, G1 and AQ1 are four different properties. Confusing them is the most common specification error in partition packages. Read → Selection 2026-11-02 Nine technical points of prefabricated fit-out A summary of what changes when a partition is bought as a system: cavity, separation, sealing, bracing, reversibility and the interfaces nobody draws.
