Title: loft insulation
Post by: sir moanalot on 05 March 2011, 10:10:20
finally got round to clearing out the loft to get it insulated (although all the crap up there probably acted as insulation anyway !!)
i went online to wicks and found buy one get 3 free deal so went for that, it went down well and took me a couple of hours- as my loft is huge. im already noticing a difference by not having the heating on for long periods. :y note if you are a british gas dual fuel customer you can get it done for free !!

Yes - just had mine done - all tanks and pipes relagged, had about 3 inches of loft insulation before now 2 thick extra layers so maybe 10 inches or so.

Clearing loft was a nightmare- starting to assess what goes back in after first cull we did a couple of weeks ago. What to do with my vinyl collection which has not seen light of day for over 20 years?

Also had cavity wall insulation done.

Current recommendation is 10 inches which is a lot more than used to be, so more than most people have.

My mother (91 yrs old) got Social Services saying she could have it done under a Government grant system.  The guys came round, said we'd need to clear the loft space including taking up the 8ftx2ft t&g chipboard.  Muggins did it, and when they rang to make an appointment, mother forgot who they were and sent them packing.  Now far less insulation than before we started the process!!!

It's worth noting that most lofts can't be boarded if you have 10inches of insulation sitting uncompressed.

If there is insulation under the laid boards they can /will lay new insulation over the top - it is all insulation after all - even the crap stuff you put up there. I left a central section with just a few inches insulation so did not have to raise boards but this will be storage/access area.

It's a bit doubtful that you can do much in a loft with insulation on top of the boards?

I have two lofts, one of which is the boarded storage area, I'm thinking of putting Celotex or Kingspan between the rafters to make up for lack of insulation.

Sounds like a good idea.  Insulating a loft at floor level not only makes it inhospitable to use but makes cold water storage more vulnerable.

Is there a down-side to doing the rafters?

As long as there is sufficient air space above the bats to allow ventilation (in case of condensation) it is OK. There is probably a thread on DIYnot.com on this subject. :y

I have 250mm under the boarded bits and 300mm elsewhere.

B&Q keep seeling the stuff for 3 pounds a roll so I just keep chucking it in!

I fixed some wooden planks to make a raised storage area for part of the loft area a couple of years ago - Must admit my back was not the best afterwards. Also had to put some ceramic pots around the downlighters.

I have some old insulation and a fully boarded loft and several layers of junk stored on top, can you really better insulation than a layer followed by a boarded floor????

Yes, big time.

The boarding is a pretty poor insulator

Sell them on ebay - you might be surprised how much you may get for them..............I sold one of my scratchy old lp's for £40 (gracious......that's the band) to a collector in russia.
Old King Crimson records are highly collectable items as well  :y

Not to bad from a good merchants but it is pricey at the DIY sheds.

There are also a few companies selling on ebay with good prices and delivery
