Loft insulation under existing boards

ian2020

I need to insulate the loft, up to modern standards, but the middle third of the loft is boarded and partitioned to make a junk/games room. I\\\'m getting the two outer areas insulated but none of the contractors I got quotes from have really offered any solution as to what to do with the boarded area. It\\\'s not practical for me to remove the boards/walls, so I would like any suggestions as to what to do with this area.
What options are there? Is it worth looking at loose fill materials? If so, how to install it? Or what about blown fibre - ? How does this work?

Any suggestions from anyone that has had this type of thing done or does it, would be helpful.

Cheers.

Insulate around the room itself. Was there ever any insulation between the joists before the room was built?

I bet it is.

What's the prob? Parquet flooring with complex marquetry?

It's a very big room, so it is not practical for me to remove the walls/boards.
There is only a small amount of insulation between the joists, about an inch or so, in patches.

From inside the un-boarded area of the attic, you can see through gap between the boards and the ceiling below. Hence my original question regarding filling this space without removing the boards.

Any other ideas, anyone?

flooring comes up quite easily. Is it chipboard sheets, or plank-like floorboards? Screwed down or nailed? Is it covered with carpet or something?

Can you lay your hands on a circular saw?

I have the same problem as Ian. I live in a 1920s house with a boarded attic. There is blown insulation in the outer area but it has proper floorboards which I do not wish to disturb. I had thought of putting battens with insulation between and then using flooring sheets. Is this feasible. Also someone has plastered between the roof supports and it is grotty. Can I put insulation rolls [the metallic sort] over this or is it a 'chip off job? [sorry about the terminology fellas but I'm new to this and I am starting a bit late in life!]

Many years ago we used a two part expanding foam to fill buoyancy tanks within our boat.

No doubt something similar could be used, just make sure there are escape holes in case too much foam is produced

I'm in a similar situation to the gentleman who started this strand, except that, as well as having a substantial portion of the middle part of the loft planked over, there is a large sliding glass panel that provides access to the loft and light to the large hall via a window in the roof of my bungalow. Are there any cunning ways to improve the insulation of the loft in this situation? At the moment what insulation there is comes from three to four inches of loose fibreglass wool beween the joists while I've stretched a layer of film across the frame of the glassed panel.
Best Wishes,
