Title: Loft insulation
Post by: justboatonic on December 04, 2011, 07:42:48 pm
Had some work done in my loft recently and just found out when I went in to get the chrissie decs out, that the 'workers' had removed a lot of the existing fibre insulation from between the joists all about the loft (they were installing a new tank and pipes for a shower, also found they havent lagged the new tank or pipes but that's another story!).

When I inspected the insulation, a lot of it looks to have naturally compressed or, had been teased out to appear thicker by the original builder (hmmmm!). So, looks like I need to top up or replace the existing stuff.

So, has anyone 'topped up' their loft insulation ie more insulation roll on top of existing stuff or has it been a case of remove all the old stuff and put new insulation in? If so, did you use a different product? I notice places like B&Q now do things such as insulated timber boards, solid blocks of styrene and the like.

I just got some additional rolls from B & Q and my lad and myself laid it on top of existing insulation.

Hi ,
   just remember not to insulate UNDER the water tank as it relies on heat rising from below to prevent it freezing (as my next-door neighbour discovered last winter - messy and expensive!)

 Make sure you dont sandwich cables between the layers of insulation or cover any down lights if you have them in your ceilings.

Recomended amount is 270 mm minimum. More does no harm but the law of decreasing savings applies. Id go for 400mm. as the stuff is compressed in a roll it does spring out somewhat. At £2 a roll its cheap as its subsurdized by the power companies. Please remember to leave space arond the eaves for ventilation and dont forget your loft hatch. Have fun im clumsey and once put my foot through a ceiling.John.

And something else the insulation manufacturers omit to mention is that unless treated, it also keeps vermin nice and toasty on these cold nights.

Possibly better for vermin if you use the wool based insulation. It will be comfy for them.No itching. John.

Definatly DO NOT cover downlights.   >>:-(
The Australian government subsidised roof insulation to help the building industry recover from the GFC.
There were so many house fires from this cause, due to shonky installers, that they had to stop the programme and have registered inspectors check every installation.  <*<

Oh dear, until the last Post how many have been conned!? As to thickness go and ask Wolseley (soon to be Jewson), don't pratt around with all else otherwise you will get nowhere! £1 per roll, get on and soon, eh! Before it's too late.
