Test and Assessment Reports

Testing undertaken in accordance with BS EN ISO240-3:1995 revealed a timber doorset assembly with no seals fitted around the perimeter of the doorset achieved a Rw23dB rating. This falls well below the minimum specified in Approved Document E which is 29dB. When tested again with the Astro AS Quad Flipper Seal there was an increase in the performance to Rw34dB.
