TriSound

The TriSound Acoustic Door Core is supplied as 3-ply core material with cork outer layers sized at a nominal 2000mm x 800mm. It requires making up into a door blank by adding timber perimeter and Chipboard or MDF substrates.

Once complete, the door blank can then be trimmed, lipped and faced to make a door.

TriSound has been tested rigorously for both fire and acoustic performance, achieving both 30 minute (S3K variant) and 60 minute (S3D variant) when tested to BS 476: part 22: 1987. Acoustically, performances of up to Rw44dB sound attenuation have been achieved when tested to BS EN ISO 717-1:1997. Cold Smoke seal requirement to BS 476: part 31.1: 1983 comes as standard with every seal combination.

TriSound is now also available as unlipped blanks. Standard leaf size (926x2040x54) available ex-stock with special sizes available on a 3-4 week lead time.
