The TriSound dB+ Acoustic Door Core is supplied as 3-ply core material with cork outer layers sized at a nominal 2000 x 800mm plan size. 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.
