Installation guides and catalogues

For the most common layout with a 600×600 mm tile: 0.232 main runners of 3600 mm, 1.4 cross tees of 1200 mm, 1.4 long tees of 600 mm, 0.7 hangers and 2.78 tiles per square metre. Schemes with a higher load rating double the number of main runners and hangers. The full calculation for every scheme is in the T-profile installation guide.

Hangers are spaced at 1200 mm along the main runner, with the first no more than 600 mm from the wall. On schemes with additional hangers the spacing is reduced — exact figures are in the consumption table.

An angle L profile 24×19 mm or a wall W profile 28×30 mm, 3000 mm long. The L profile is simpler to install; the W profile gives a closed edge and a neater junction with the wall.

No. The grid clips together: main runners connect to cross tees without any metal-cutting tools. Cutting is only needed around the perimeter. That removes wet trades and curing delays from the programme.

The minimum drop is 120 mm. The actual drop is set by the services: ventilation, cable trays, sprinklers. Baffle systems with integrated lighting need extra space for the luminaire.

Two ways. On a frame — metal profile or timber battens, the standard option for ceilings. Bonded — when height cannot be lost, mostly for walls. Both instructions are available for download above in four languages.

KRAFT profiles are tested by Instytut Techniki Budowlanej, EU notified body No. 1488. Declarations of performance have been issued under Regulation (EU) No 305/2011 to the harmonised standard PN‑EN 13964:2014‑05, with Euroclass A1 reaction to fire — non-combustible. Alongside these are test reports for sound absorption and fire safety.
