Another “hello” introduction post

[Peaklander]

Hi all

As a frequent user of a Land Rover forum I don’t know why joining one such as this didn’t occur to me sooner. Anyway, I’m here and would like to say “hello”.

I landed on this forum with a Goooogle search that took me straight into the diy blown beads cavity wall insulation thread here. I’d just  had a ‘eureka!’ moment a couple of days ago, when I realised that topping-up our existing cavity might be a DIY job. I’m sure that the blown beads installation we did over twenty years ago has slumped. I’ll prove this with a thermal camera once the weather gets colder but you can just feel that it isn’t effective.

 

I live in the Peak District and have been in this house for 25 years but after going crazy sorting it out during the first three or four years, since then it has had plenty of maintenance but no major changes.

It’s a 1960 build, two storey detached house with rooms in the roof. Roughly rectangular in shape, we have a 17m ridge and it’s almost 6m ridge to eaves. The eaves are just above the top of the ground floor windows.

Why am I here, I hear you ask? Well the cavity top-up is just a minor detail. This is the list of work we are starting in the new year.

 

Strip roof back to rafters

Top-up bead insulation by pouring into the cavities now exposed

Insulate the roof to U=0.16 with PIR between and above the rafters with breathable membrane and counter battens above

Fit in-roof solar panels

New roof tiles

We also have a longer term plan to fit an un-vented hw cylinder with immersion heater to take power from the solar panels/battery and prepare the pipe work to create zones, to include a new zone to an ufh manifold. Then we will probably lift 60m2 of suspended ground floor, insulate and lay pipe work with biscuit screed. To finish we will lay engineered floor.

 

Hello.

Welcome.

There are a couple, or more, people on here with old Landrovers.

Between you, you will almost have enough to make a working one.

 

As for blown beads. Work on the airtightness first. While you are doing that, try and find a supplier of them. Seems individuals have had trouble getting them.

Ha, that old Land Rover joke! Mine is a young 28 year old Defender and it’s in prime condition. Much like Trigger’s broom it has had it’s fair share of replacement parts but it has taken us all over and as far away as Greece twice.

 

Thanks for the air tightness advice. I am hoping to do most using gravity as the cavities will be exposed from above. We have had it blown in years ago and none leaked at the bottom. We have suspended floors and so I can see.

 

I have found a few sources but my, they are pricey. Cheapest is £16 for 10cu ft bag.

Harrrrumph.... mine was a 1985 vintage. Leaked water out almost as fast as it leaked in..... Sold it to pay for concrete wasted in the bursts on our ICF adventure. 

I'm gonna cry now .... cry myself to sleep.

 

No - thanks , I'm OK, don't worry.
