Once the fundamentals were sorted, it was time to start building the internal framework. I bought a shed-load of pressure-treated timber from my local timber merchants, which they suggested I would be able to carry home (just around to corner) and I wouldn't need to bring the van around. That walk was the longest in my life, and the closest I've come to feeling the weight of the world on my shoulders.
After recovering from the walk I could get down to measuring and cutting, measuring and cutting, measuring and cutting... ad infinitum.
Most of the initial framing would also serve as diaphragmatic bass absorbers, hence why you can see the walls are made up of rectangular shapes to house the bass trapping while fitting around existing structures and access points.
Any contact with the floor or ceiling was decoupled using neoprene strips, to stop the impact noise being transmitted from one surface to another.
For the diaphragmatic absorbers to work properly, all gaps were filled with acoustic sealant, as the box needs to be an airtight chamber.
Once sealed I could start loading the Rockwool into the frames.
Overall, the framing consists of several different 'layers' around the room. A base layer for.... bass trapping, a secondary layer for mid-range absorption and diffusion, and the front wall layer that would house the speakers and TV. The last two layers we'll see more of as the build progresses, but you can see the start of additional framing here...
With the framing underway, I had to wait for the arrival of a specialist material required to finish the bass absorbers. This halted some of the progress, so my attention turned to the ventilation which we'll look at next week!
