It’s from Europe not the government. Good point about elderly people paying exorbitant money for external wall insulation.
As I’m living in a terraced house, I’ve put a bit of effort into insulating my roof. However, rather than insulate the walls, I’m planning to thin them out and as part of a plan to reduce the thermal insulation of the party walls.
I am also doing calculations on a longer term plan for installing heat pumps to draw heat from my two next door neighbours’ homes (they both have central heating, so there’s not really any point in me running and maintaining a heating system).
That’s a good idea. May I suggest you thin the wall, put up piping along the wall then lay insulated plasterboard on top of that. This will prevent your heat leaving for your now colder neighbour’s house.
I also recommend installing the piping on an upstairs wall - as the heat will rise in your neighbour’s place.
Sometimes - not always. Having a well insulated house is more comfortable than a poorly insulated house heated to about the same level.
Have you actually looked at the rates that are charged for these and worked out the costs? I suggest you do. It’s a minimum wage job doing BER certs - only the naive, stupid or desperate would get into the business.
would broadly agree on that. It’s maybe a kind of low-level welfare to the construction sector (doing certs, and then maybe more significantly doing work to address what comes out of the assessment).
What I’m wondering about is how to explain to the neighbours why they get so much condensation on the party walls. I’m going to pay the local Parish Priest a few bob to back up my story that there’s a long-drawn-out exorcism going on.
While you’re at it, tap into the neighbours electricity cables.
Look upon it as a subsidy paid by them to you for being such a happy neighbour and cheering them up whenever their electricity bill arrives.
Its always good as well to maintain a chilly disposition, as this tends to attract heat from other people.
My rental house is probably in the D-E area of the rating but my energy costs never go over €2000 a year. Those figures sound entirely plucked from the air. Though on the elderly people getting external insulation, that’s mostly paid for by government grants. Up until a couple of years ago the cost to the homeowner was negligible.
Typical cost of sem-d insulation is €12-14,000, grant available is about €3000. Big difference.
External insulation? I’ve been quoted a fraction of that for beads pumped into walls.
Beads are different to external insulation. External is literally insulation applied to the outside of the dwelling, so you have a new ‘plaster’ finish as well. Beads are less disruptive & significantly cheaper, but not as effective as External.
Edit: unless used in a new build with really wide cavities.
Can any house be pumped with beads? And if not how can you tell if suitable? (for a dunce)
Yeah I know that - was just asking to make sure you were quoting external insulation costs. People can insulate their homes using beads for significantly less than external insulation with an extremely short pay back time.
Depends on the type of construction of the property to be honest. Most houses (before the timber frame houses of the boom) from 70s anyway and some before were built with an inner leaf of blockwork, a cavity (50-100mm/2-4inches) and an outer leaf. Some were uninsulated and some had 50mm polystyrene against the inner leaf and can be pumped. 50mm or less isn’t generally recommended to pump - the cavity is there to let any water that gets through the wall run down without hitting the inner leaf of blockwork so pumping a narrow cavity makes it easier for water to bridge the cavity. Timber frame shouldn’t be pumped either. You would need to check the construction first.
I’m not a specialist in this area but there are constant debates over best types of insulation (even for new construction) and which is least likely for mould to grow/provides best performance/easy to install/cost effective etc.
The grants are less now but they had been much higher recently. A very common way to do it was to get external insulation on the front of the house and the cavities filled to the back and sides. The way the grants worked out meant that meant that the homeowner only paid a few hundred. And people also liked that it gave their property a ‘facelift’ at the same time. We got in numerous leaflets at the time from different companies with the calculations worked out on them. A number of relatives had it done. One in a period mid-terrace with no cavities had the external walls done for under a thousand.
Could pump all the cavities in the house with beads. Just got to make sure you’re sitting comfortably in your favourite chair before the process starts as you’ll be staying there (cosy as could be) for quite a long time.
On the plus side, your cavities will be pumped with beads.
Domestic Building Energy Ratings
Quarter 2 2014
Edit: Table 2 shows that
26% of dwelling constructed in 2010-2014 got an A rating, with a further 38% getting a B1
1% of dwelling constructed in 2005-2009 got an A rating, with a further 4% getting a B1
I’d expect that the statistics for teh one-off or self-build houses in 2005-2009 would be much better than the general statistic for the period 2005-2009 and that one-off or self-build housing represents a higher percentage of the total houses built between 2009 and 2014.
