Siena Panel

The THU Siena technical ceiling model consists of panels that have been specially manufactured to be installed on removable rails, such as the T15, T24, T35 and DP profiles in their varying sizes. Once installed, these panels are packed one next to the other along their longest side and suspended 10 mm from the support profile on their short side. 


Panels are pre-lacquered in THU 9010 white or THU 9006 silver (check availability in other colours) and can be made with their visible surface machined in any of the perforations available in the catalogue (square measuring 8×8 mm or 5×5 mm, or round in diameters of 6 mm, 2.5 mm, 2 mm or 1.5 mm, or extra-micro in 0.7 mm). 


Each panel is fitted with a thermo-adhesive acoustic fleece on its back. Profiles are fixed to the framework via threaded rods and bracket hanging pieces with a gap between brackets no greater than 1.2 m.

Installation and Cleaning

  • Panels must be stored in dry, well-ventilated places away from heat sources and out of direct sunlight and rain.
  • THU Profile ceilings are installed during the last phase of construction, meaning once all enclosures and facilities have already been put in position. Ceiling models that are protected by a plastic film should have this film removed as soon as possible to properly ventilate the false ceiling once installed.
  • The area where the ceiling is to be installed must be clean and free of obstacles that hinder the installation procedure; furthermore, all other construction work (plaster, dry construction, etc.) and painting must be completed in the spaces where the false ceiling is to be installed to avoid stains and dust build-ups on its sheets.
  • The area where the ceiling is to be installed must be clean and free from obstacles that hinder the installation process.
  • The ceiling should be installed in ambient conditions of temperature (15-25ºC) and humidity (35-75%).
