But this got me thinking, does the same apply to mineral wool products? These micro-convective losses are something that doesn't seem to get talked about much - people just seem to quote U/R-values and leave it at that. Obviously mineral wool boards tend to be denser than fibreglass batts, but I guess they're still considerably more gas permeable than e.g. EPS.

Does anyone have any concrete info on this? I'm looking at products for EWI and I don't want to make an expensive mistake - particularly given that EPS seems like it's by far the cheapest board-type insulation available to me. From an idealistic "green" perspective I'd rather not use a petrochemical product, but from a pragmatic point of view, I want something that is effective at a sensible price point, and savings will only be reinvested in various other efficiency/sustainability projects. If I can do more for less, it may well be that spending the money elsewhere has a net positive impact that will outweigh the downsides of using EPS (which at least has a *relatively* low carbon footprint by comparison to some of the other synthetic materials)]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13060 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13060 Wed, 04 Feb 2015 14:45:21 +0000 laikipia
Sounds excellent - breathable, thermal conductivity of 0.113 so U value of 2.26 for a 50mm layer. With a 500mm wall with U value of 2.3 this would reduce the value by almost 50%.

It is described at http://www.hp2a-technologies.com/

It says: "The HP2A project was born when David Hoffmann, a scientist specialized for more than 20 years in mineral binder’s chemistry and Julien Blanchard director of Argilus, a major representative in the French eco-construction market decided to join forces.
A Patent called “HP2A” was created and registered at the INPI on the 27th March 2015 N°15 52615"

But when I search INPI for that French Patent, it appears to say it was issued in 1968 to an American company. I expect I don't understand INPI's English on their site.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9 Wed, 31 Jan 2007 20:27:39 +0000 skywalker

Our builder has obtained a quote for us from the same person who is making the (Conservation area compliant) front door and it is way over our budget. Our thinking is that we don't need a bespoke handmade gate. Researching online there are lots of websites who sell hardwood gates, but it is difficult to differentiate between them.

I already have a large pellet stove that heats the house but I am now looking for a small one to just heat the living room.

It needs to be 750 high max and room sealed.
I can find stoves that are room sealed and stoves that are the right height but not both.

Anyone know of anything?

The nearest I have found is the MCZ Thema which is the right height and has an air inlet on the back.
It is not advertised as room sealed but can anyone see any reason why I cannot connect that to my external air supply.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13874 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13874 Tue, 08 Dec 2015 13:45:40 +0000 Paul_B

Plan A would include using conventional gloss paint (from a recycling scheme) on top, but I imagine that might also have to be reconsidered?

I'm currently trying to insulate the pipework under my suspended floor. Where there are straight runs I am using the “normal” hollow tubes that split then wrap around, but most of the pipes are not straight (some seem to go in sweeping arcs for no reason at all). In a number of places they come together for a short distances before separating again and there is no room fit the normal insulation in-between them where they run alongside each other.

I suspect I'm using the wrong search terms because I can't see anything that is recommended for use in these cases. Is there a product suitable for wrapping around hot/cold pipes then taped?

The closest thing I have seen* is “felt pipe sleeving” but it looks like this is supposed to be slipped over the pipe while it is being fitted and if I managed to get it wrapped around the existing pipes I'm not sure how much insulation it would provide.

My priorities are compactness, portability, quietness and accuracy (for joinery). We're a self-build with no workshop so I need to get it out and pack it away each time I use it. And I'm often working on the weekend so don't want to piss the neighbours off with noise.

Is the TS200's accuracy (according to reviews on their website) and assumed relative quietness (given an induction motor) worth the relative lack of portability and cutting depth? The GTS10J is 103-116 dB; couldn't find rating of TS200.

I think airtightness is fundamentally more important than U value, because you can add extra insulation elsewhere (to some extent), but you can't add extra airtightness. (I would want to use MHRV.) This suggests to me that a "manufactured" solution will be better than something handcrafted, but I guess that's not necessarily true. I suppose the best U value for the glass will be soft coat with Krypton fill and warm edge? Does anyone use that?

Brands I know about:

USA: Marvin, Andersen
UK: Masterframe, various timber manufacturers (which is the best?).
Europe: Vrogum]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11679 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11679 Wed, 29 Jan 2014 16:21:10 +0000 Shevek
1. Value for money and probably mid-range on our budget.
2. Super quiet.
3. But super high extraction rate.
4. Washable filter and reasonably priced charcoal replacement filters.
5. Nothing too modern looking. Simple is good.

I assume 1, 2 and 3 are contradictory priorities.

Would we be helping ourselves if we went for a canopy hood and built it into a dense sound-proof cabinet or would it not make enough difference to warrant the effort?

Are there any other left-field advances in this area that we should consider?

My window supplier/joiner guy (London Box Sash) is trying to get hold of Pilkington EnergyKare Advantage from his regular glass suppliers. We’re hoping to use this in some Accoya casement frames for the kitchen. I believe he’s also called Pilkington for further supplier advice. None of the suppliers tried thus far appear to stock it, or in some cases know of it.
Sourcing the standard EnergyKare or equivalent doesn’t appear to be a problem. The higher Advantage spec which claims to achieve very low Ug values of 0.9W/m2K “triple glazing performance with two panes of glass” as described by the manufacturers, appears to be a bit elusive however..

Has anyone had any success in sourcing this stuff ?

They appear to have only taken one sample of each, and you won't find out which lamps are most consistent or reliable. But they have measured the bulbs' technical performance with almost ridiculous precision. 3979K colour temperature, anyone?

They wisely advise 'Before you buy the lamps, you should check what the beam looks like. Some have coloured edges or don’t have a smooth gradation of light from the centre to the edge.'

Basically even if there are no obvious cracks the water seems to be making its way through somehow. It's been 4 years since painting so that needs doing, but I'm wondering what is the best product to use?

I've looked at a few other solutions like StormDry cream, or perhaps cheaper waterseal sprayed on then painted over. We may eventually clad the whole house but if there's a long term solution it would be nice to avoid this.

The masonry is all in good condition and very strong - no render coming off or anything like that. There are some small cracks on the chimneys but they're not big enough to repair easily.

Do you agree, or is there some sensible use for the lamps?

Come to that, there's the same problem with fluorescent tube fittings. They almost inevitably come with some tubes of the wrong colour (we only like daylight). And increasingly there's a problem even buying anything other than 'warm white' lamps.

Are there any solutions, or do I just keep junking lots of perfectly good lamps?]]>
