    cavity wall U values error

    Right on Tone! insulation didn't get invented until the 70's, further to this,any house that has had urea formaldehyde foam cavity insulation fitted probably aint insulated anymore cos the stuff disintegrates over time

    cavity wall U values error

    I wonder who supplied these figures initially n were they theoretical or a 'real life' study?

    cavity wall U values error

    A figure of 1.6 is thrown about for a cavity wall and 2.2 for a solid wall, however that cavity wall figure is wrong. I've just drilled 2" holes in my 70's cavity walls to fit polystyrene beads n the draught flying out of them blows the beads back out!! prior to doing this, I could feel the...

    Hive thermostats general question

    EM...............you've clearly got a massive brain....can I buy some of it from ya?.........sadly, mine aint! I have a 1yr old condensing combi, my existing progstat is too difficult to program for my small brain PLUS it don't have a boost (switch on for an hour) button, the hive looks...

    Hive thermostats general question

    Lads.................I am only a simple bloke, TRV's talking to stats etc etc put the fear of G** into me PLUS spending hundreds of pounds to save a few pence when I can just turn the stat down is all a simple bloke like me needs...........................BUT.................the hive...

    Hive thermostats general question

    I have a combi so I only need single channel, I also want to hardwire the thing n have no intention of talking to the thing on the phone or internet. Does that mean I can just buy the thermostat n it will work?

    A progstat for a simple bloke?

    I wish I had stuck to WB...........this intergas job may have only 4 moving parts...........but that aint much good if the electronics are sh1t!! after endless problems right from the instal, I had to call out an Intergas engineer under warrantee, he came n said 'yes a dodgy Korean circuit...

    A progstat for a simple bloke?

    I think it's a TP1 M...........sadly the boiler has never worked properly with any of the 3!! different stats that have been fitted (pump and/ or boiler stays on, therefore I had to install a 240volt contactor to stop the backfeed)

    A progstat for a simple bloke?

    Good man DnL, so I went on the hive site.....................Jeez, what a nightmare, smarthome, smartlights, smartcameras..............give it up boys, you're scaring normal people off!! add another tab called Dumbhome and you'd have held my attention!! I gave up after 5 minutes of trying to...

    existing progstat is a Danfoss TP one ......................when I want to save money on gas, I turn the boiler off 15 mins earlier

    A progstat for a simple bloke?

    Good man Muggles....................boiler is 1 yr old, heats a 5 bed house (not interested in that opentherm nonsense) no idea what model, current progstat is wired (no volt contacts)

    A progstat for a simple bloke?

    Everyone in the world is obsessed by mobile phones n apps..................except me! I need a new progstat for my intergas combi..............I don't want a nest n I don't want to talk to the stat via my mobile or the internet, I realise this makes me a weirdo, but heyho that's me. What I do...

    What are these things in between bricks?

    I remember having a paraffin heater in the kitchen................wind the wick up, then lower to get blue flames, all the wardrobes had black mould in n we didn't know why (water from paraffin), we lived in a victorian semi (15ft high ceilings 13" walls, the landing wallpaper drop was A...

    Is building regs needed?

    I'm extending the garage n porch across the front of my house (3 feet forwards and 25 feet across), It won't be 'lived in', you've told me I need PP, but can I just go ahead once I have PP or will I need regs approval too?

    retrofit cavity wall assumption inaccuracies

    Cavity walls were 'invented' to stop penetrating damp associated with 9" solid walls cos that naughty moisture can run inside the cavity..............but..............if you live in a low wind/ rain penetration area, have good pointing, weathertight roof n downpipes, you don't need the 'defence...

    PP for extending an existing porch and garage?

    Bugger!..............fank yoo Tone, my next question then is, will this 3ft x 26ft (double width garage) extension need building regs approval too?

    PP for extending an existing porch and garage?

    I have a 1960's detached house with an integral garage, I want to extend the garage forwards by 3 feet in order to butt up to the front elevation of existing porch (this will also increase the width of the porch by 4 feet), I know the permission document says permission is needed if you want to...

    retrofit cavity wall assumption inaccuracies

    Wise words Wood.................all those clever numbers are wonderful in a theoretical situation, but reality has an annoying habit of sticking 2 fingers up at theories.................However, if we just think of wall U values, surely they are an accurate measure of heat loss through a...

    retrofit cavity wall assumption inaccuracies

    Wood................when is a clue not a clue?..............when I don't have a clue! those numbers are great...........if you know your stuff, n I don't. Mikeey don't forget that PUR foam only has superior insulation properties because of the gas in the bubbles, when that 'gasses off' it's no...

    retrofit cavity wall assumption inaccuracies

    I'm all for insulating everything I can (including the 55mm cavity walls in my 1960's house with polystyrene beads).....................BUT...............whilst being effective, it probably aint as effective as what people assume. 2" of any insulation will only slow down heat loss, would anyone...
