Flooring recommendation.
Query
I’m getting ready to put a stable tallow wooden ground over a yellow tongue structural ground on timber joists. It’s 130×19 mm characteristic grade. My query is – what are my choices for managing the growth of the ground? The area I’m involved about is a wedge shape- the widest half is 12 m huge and the slim finish is about 9.0m I hope there’s a approach that may keep away from the normal growth joint each 6m. A mission I labored on up to now used sheet metallic packers to create small gaps each 4 boards to permit a wider ground with out noticeable growth joints. Ideas or recommendation could be a lot appreciated.
