To determine which tile you have try taking one down and looking for a code on the back. Tiles made by Armstrong have a unique reference code starting with BP which will confirm the tile you have.
We offer standard sizes 1200x600mm and 600x600mm. These references are the industry standard terms but the tile dimensions actually measure 5mm less in reality.
Ceiling grid is measured by the width of the surface that is visible from the room.
Generally ceiling tiles are made from a mineral fiber of wool and clay. Metal tiles are also available.
The sound attenuation dB score measures the acoustic performance of a ceiling tile. Armstrong Perla, Ultima+ & Bioguard Acoustic are thicker tiles that are designed for excellent sound proofing.
Firstly perimeter trim is installed around the edge of the ceiling. Main runner is then fitted across the length of the room and fixed to the roof above using brackets and wire. 1200mm cross tees will then be installed between the main runner lengths. If you have 600x600mm tiles then you will also need 600mm cross tees to be fitted in between the 1200mm cross tees. Finally the tiles will be installed. If tegular or microlook tiles are being installed then teg blocks will be required to prop the tile edges up on the perimeter trim.
