			<![CDATA[We want to put a  solid  wood floor in our living room where the whole floor just has been replaced. We have now new floor joists with an insulation board between them and on top of that is a wood chip board. How do we best fix the solid wood planks?  I would like to have them nailed but have been told it has to be glued. The offer also includes a moisture barrier (seems to be stuff to be plastered under the floor - it is shown in kg in the offer). If it is solid wood it may expand or shrink  - would that not be a problem if it is glued?  I just don't like all these different chemicals in my living room - if it is nailed down I don't have to worry about anything coming out from the glue.]]>

			<![CDATA[I produce a book called the Housebuilder's Bible which is widely read by selfbuilders and small developers in the UK. I am about to start work on the 8th edition which is due out at the end of this year. Every edition so far has been based around a new house built during the past year, which means that it is up to date with current regs and building practice. Ideally it needs to be finished now.<br /><br />I am not looking for experimental houses, nor exemplars, merely something which meets or slightly exceeds current regs, in particular Part L which despite coming into effect in 2006 seems to have been widely ignored by building control until 2007. Has anyone on the list (or their friends) been involved in such a project? Would you like to have it written up as the benchmark house for my 8th edition? I would need plans and costings and permission to write about every (or at least most) aspects of the build process.<br /><br />If you don't want to reply to this list, then email me at markbrinkley@mac.com<br /><br />Mark]]>

			<![CDATA[I would be grateful for advice regarding heating options for our house.<br /><br />It is an old 2 up 2 down Cornish cottage with cob walls and a â€˜newâ€™ extension placed in the 1970s- giving a small kitchen, further upstairs bedroom â€“double height hall and a very cold flat roofed utility  (which was the old coal store/store room) and an attached garage which sucks heat out..<br /><br />We had an oil aga and poor oil central heating via radiators â€“ all of which I have taken out.<br /><br />In my rashness to get things done we have installed solar water with secondary immersion heating but now have realised that we would be unable to use an alternative water heating source in the winter without changing the new cylinder- which we are not going to do.<br /><br />We are going to convert the garage and put a pitched roof on the flat utility and convert both to bedrooms and put a porch outside the hall and insulate, insulate insulate (as best we can).<br /><br />For heating we currently have a wood stove in the lounge which works fine but does not get through the cob walls and the rest of the house remains cold (but not too bad- we are still in tropical Cornwallâ€¦).<br /><br />I like the idea of a ceramic stove and thus my thoughts for improving the heating are<br /><br />1.Ceramic stove in the hall- slow gentle heat to bedrooms and utility (which will become bedroom). But they are expensive and I have not seen any positive feedback on their use.<br />Would a clearburning stove be just as good?<br />I have to say I like the idea of the ceramic stove- but Â£4000 for the Toplolino seems a lot.<br /><br />I would put electric underfloor in the â€˜newâ€™ downstairs bedrooms- which need new floors- so put good insulation underneath.- and as bedrooms will only have heating on for small parts of day. When wind/photovoltaic fall in price (which I believe they will) then look to use these to provide â€˜cleanâ€™ elec.<br /><br />Alternative might be<br /><br />2. Go for GSHP with underfloor- ok for new bedrooms as likely to need new floors but not solve rest of house. Expensive installation and still needs elec to work.<br /><br />3. Use wood pellets with underfloor- same arguments re underfloor â€“ and space for pellet burner-but wood burnings good in my book. Could use radiators with this I suppose?<br /><br />Any contacts for a heating engineer in Cornwall would also be very helpful.<br /><br />I know some of this will have been covered before and links to any earlier threads would also be appreciated<br /><br />Sorry the long missive which I think is mostly stream of consciousness- as the saying goes if I had more time I would have written a shorter letter.<br /><br />Thanks<br />Rob]]>

			<![CDATA[Thinking of using an ASHP on economy 7 overnight into a thermal store, taking out the heat next pm/evening into UFH, and the forum seems to think it feasible.<br /><br />How does one work out how large a thermal store is needed?<br />Also would I just set the ASHP to run full power? (it is inverter driven so can be moderated to match the load, but as the load is the next day it seems some inspired guesswork might be needed!)]]>

			<![CDATA[Hi I'm a new starter, just moved into a 70's challet bungalow with scant insulation. 1&quot; glassfibre bonded to underside of roofing felt, and 250mm glassfibre on loft floor (about half the ceiling area of the building). Our energy provider is offering to fill the cavities with pumped mineral wool, which i believe has a thermal conductivity of 0.04 W/mK. I understand  Platinum polystyrene beads have a value of 0.033 W/mK. which by my calculation is 15% better. Can you please comment on the relative merrits? and also on the relative merrits of hemp batts versus mineral wool to lay on the ceilings and pack against the stud walls of the two large uninsulated side cavities.<br />Thanks  Malcolm]]>

			<![CDATA[Hi,<br /><br />I'm planning a new build in northern Spain where the frame and floors of the house will be constructed using pre-cast concrete slabs.  This means that the roof of the basement (which is planned to be used as a cool storage space) and the floor of the ground floor will be a 10cm concrete slab.  I would also like to make use of the winter sunshine to heat the house passively using big windows on the south side and a thermal mass for the floor.  But I'm not sure whether I can use the concrete slabs themselves as thermal mass, or whether I should lay down insulation over the concrete slab and pour some more concrete on top of that for the thermal mass.<br />The problems I can see with using the slab as thermal mass is that it will be thermally connected to the rest of the concrete frame (which won't be insulated) - and there could be significant heat loss into the basement.   But two layers of concrete seems like an excess.  Could I instead use the concrete slabs as thermal mass, but then insulate underneath them to prevent heat loss to the basement?<br />Any insights would be appreciated.<br /><br />Stephen]]>

			<![CDATA[Hi, new to forum, so forgive me if I am repeating an old topic i havent seen.<br />I had loft conversion built in my 1962 bungalow some 16 years ago. Best building practice has moved on considerably since then. The room walls are created using plasterboard fixed on to 20mm batens, which are in turn fixed on to roof struts. Approx. 100mm insulation throughout, No vapour barrier is present!  I want to increase thickness of insulation to recommended 270mm min. I do not have a problem with condensation/dampness at present, but should I consider using a vapour barrier paint on the plasterboard to reduce effect of condensation in loft area.<br />If so should the paint be applied where possible to the cold side of the plasterboard mimicking the effect of a normal plastic sheet vapour barrier]]>

			<![CDATA[Reposted from Jon<br />Any comments, good or bad, on this project <br />The 'ringshell' project is aimed at producing inexpensive, minimum materials content, liveable space wholly covered with living soil capable of supporting organic growth. This is intended to be an open source project leading to a 'ready made' mass-produced solution (aka 'doughnut city'): Some of the reasoning within this text simultaneously solves prototype and mass-produced questions.<br /><br />http://www.ringshell.org<br /><br />The Project has now been running for many years and has proved to have many more issues than was originally envisaged. Govt &amp; local consultations were started in 2003 following the initial development work and now winding into a prototype planning submission.<br /><br />The site is a work in progress so apologies in advance as it is not as technical as it would be if I had the time: Technical backup exists as a large number of papers and sub-projects (most of which haven't been formally written up)]]>

			<![CDATA[We are building an extension to our property in Southern Italy that will have a SW facing glass wall.  The building will have a pitched roof with a proposed overhang of 1.5M to provide shade.  We have also paid attention to passive solar and have some walnut and olive trees quite close to the glass wall that will provide shade in summer and shed most of their leaves in winter.  However I am concerned that the afternoon sun in this part of the world can be high and may clear the trees and the roof overhang may not be sufficient.<br /><br />Are there any calculators out there that I can use to work out where the sun will fall during the summer months?<br /><br />Attached is a picture to explain the set up <br /><br />Many thanks for any help]]>

			<![CDATA[Hi there. I have been asked to install an EPDM membrane for a client. They have also asked me to install the insulation. The architect plans state a built up felt roof but the clients have choosen EPDM.<br /><br />So the plans state as follows:<br /><br />timber joists<br />firring strips<br />low emissivity foil vapour control layer<br />110mm Kingspan TR31 Thermaroof with 6mm plywood upperfacing<br />Built up felt (change to EPDM).<br /><br />As I have never installed insulation before I have a few questions which I hope someone can answer.<br /><br />Is there a kingspan product suitable for a fully adhered EPDM system that incorporates the insulation and the vapour barrier?<br />Do I need to lay down a deck underneath the Kingspan first.<br />What fittings do I use to attach the insulation to the joists?<br />When I am fitting the fascia boards the screws, it would appear, will have to go through the Kingspan. Is Kingspan capable of holding a screw or pin well enough to hold the facias in place?<br /><br />Thanks<br />Harry]]>

			<![CDATA[I realise there are many variables but can we attempt to put a typical figure on this? <br /><br />I'm thinking of the existing house stock as a whole, many of which has retrofit insulation. <br /><br />U-values measure fabric losses but take no account of how air circulation and ventilation affect them. For example, air circulation in and around dot and dab plasterboards, or in a ventilated cavity with rigid insulation boards; or in an eaves ventilated loft with mineral wool. <br /><br />My starting guess is that the bottom end of the range of air/ventilation losses is least 30%. What is the top of the range?]]>

I know what to expect with Cedar boarding but this is unknown to me. Reason for asking is that I have a client who wants to use on a 12 storey new build, I'd hate to see a scaffold going up every 5 years or so!]]>

			<![CDATA[We've recently moved into a small cottage near Shepton Mallet in Somerset, that has sufficient woods with the property to make it self sufficient in wood. I reckon/hope.<br /><br />The cottage has an Aarow Astra Large (that I believe has seen better days) rated at 4kW to the room and 12.5kW to the boiler, that used to drive the central heating and the hot water. Three years ago the occupiers had a 20kW Ideal Classic LPG boiler with a great big tank installed, and made that heat the central heating, but not the hot water. Rather unfortunately for us, the gas boiler broke a few days before Christmas, in the -4C cold snap, and it was just fixed yesterday, and it cost Â£500 (and on top of that, the day before the boiler blew, calor refilled the tank at a cost of Â£360). Few issues there, one of them being that apparently that boiler only costs Â£480 new.<br /><br />Fortunately the wood stove still does the hot water, so it wasn't all a disaster.<br /><br />I talked to the gas boiler fixer man about my (perhaps naive) idea that I could replace the Aarow Astra with a newer wood boiler with the latest clean burn triple play technology, such as the Charnwood Island III, hook that back up to the central heating as well as the hot water, and use a neutraliser (like the dunsley baker) or the heating innovations h2panel, both of which I found out about by reading the fora here.<br /><br />Gas boiler man said &quot;I've fitted two neutralisers and removed ten&quot; ... &quot;removed them because the owners wanted to fit pressurised [fossil fuel] boilers&quot;. He also said that it's hard to get the neutral point to be correct to make the systems effective.<br /><br />Gas boiler man reckoned that because the pressurised fossil fuel burners are about 7% more efficient than the non pressurised ones, that's all that will be allowed to be sold in a couple of years time.<br /><br />I'm looking for some advice - does anybody have any good stories to tell? Is what I'm thinking a good idea? ... should I just install a new stove and remove the LPG system? ...is there a better solution altogether?<br /><br />I am trying to make sure I do the rest of stuff to make the house warm - had energy save round yesterday to estimate for cavity wall insulation and loft insulation (didn't have much confidence because he went into the loft, which has boards down, and on top of the boards, loads of boxes and stuff, and said &quot;we'll roll down a load of 20cm insulation&quot; and just did not even think about all the actual stuff IN the loft), and the cottage is double glazed.<br /><br />Thank you for any advice!]]>

			<![CDATA[This post is tied in with my earlier &quot;Tricky Loft Insulation&quot; discussion, but I thought it merited its own space!<br /><br />Do I HAVE to have a ventilated loft? If so, does the ventilation have to be at the eaves, or can I just put a couple of vents in the gable end above the level of my insulation? It works with airbricks for floors, why not roofs?<br /><br />If that's acceptable, can I then stuff insulation into the eaves? as I said in my earlier post, I have a roof pitch of roughly 20-25 degrees and if I leave an air gap of 50mm at the eaves, I will only be able to get about 50mm of insulation in. Or is the main thing that the insulation doesn't touch the underside of the roof? The roof was built in the 70s - it's felt covered, laid over sarking boards backed by those soft crumbly chipboard sheets that seem to provide some insulation on their own.]]>

			<![CDATA[We're having to start afresh with a new design for our plot, having lost our planning appeal.<br /><br />We're replacing a farm house that is suffering severe subsidence. Though the plot is reasonably sized, we have a small (13 x 5m) listed barn on the site. As a result, conservation want to ensure that any new dwelling leaves the barn as the dominant feature which puts very tight constraints on the size of building.<br /><br />The new design we're looking at is essentially a room-in-roof barn shape which we feel is excellent and works very well on the site. The tight constraints are pushing us towards SIPs panels to achieve good insulation whilst keeping the building envelope as small as possible (and most importantly, keeping the ridge height low).<br /><br />It looks like it will be impossible to avoid MHRV. I'm disappointed because it will involve a costly system that will have to be designed very well to ensure even and complete ventilation (a black art I have little faith in), will require maintenance to maintain efficiency and will introduce unwanted noise to the house (we live in a very rural location, so noise intrusion is an issue). However, I've heard of problems with summer overheating for room-in-roof designs, and passive stack ventilation wouldn't appear to work without a decent loft space above occupied rooms, so it seems there is little choice.<br /><br />The heating is likely to be UFH on the ground floor, rads upstairs.<br /><br />So here are my questions:<br /><br />Are there any other construction techniques that would allow room in roof and high standards of insulation (U values of ~0.20), without becoming impossibly thick and complicated/expensive to install? Most of them seem to work out as being 400-450mm thick and the detailing of insulation and rafters seems to be a complex job that will make it difficult to achieve consistent insulation and low air infiltration rates.<br /><br />Are there any other options for ventilation that would work with this sort of design? Are there particular MHVR layouts that are more effective at distributing fresh air without transmitting mechanical and air-flow noise?<br /><br />Comments and ideas are welcome. We're pragmatic about achieving a design that ensures a healthy internal environment and low carbon footprint without costing a fortune.]]>

			<![CDATA[Not sure if this fits here but I donâ€™t see a specific ecology section â€“ I am interested to hear from anyone who has built, re-built or refurbished around bats. Specifically I am interested in what timber treatment has been used or even pre-treated timber that may have been bought in?<br /><br />I had an ecology survey done as part of the planning process and will be re-roofing. I am interested in what others have done/been required to do to accommodate bats in their build. So far I had come to the conclusion that a Boron based treatment would be the way to go but as ever I am open to new thoughts.]]>

			<![CDATA[ASHP would be much cheaper with Economy 7 (c. 1/4 the price it seems), but the heat would all be at exactly the wrong time (coolest in the evening unless using Economy 10 perhaps). Partly tolerable with a large enough thermal mass, but not ideal.<br /><br />Could it work with the ASHP heating a thermal store overnight, then the heat being extracted (Heat exchanger) when wanted?<br />Problems I see:<br />1. ASHP is perfect for 35oC UFH, but if thermal store is for both CH and HW then presumably 55oC is the minimum and COP falls to c. 2.0<br />2. ASHP at night is using colder air than daytime so COP falls further. Not sure what COP is for ambient 3oC output 55oC?<br />3. As COP falls, some of the eco benefit of ASHP disappears (but any COP is still renewable).<br /><br />Does this mean that ASHP on Economy 7 at night at 55oC is no better than standard rate daytime at 35oC?<br />(or am I looking at quite the wrong way?)]]>

It has good height and a solid starir case into it and is very dry. There are no windows and I know that it would be best not to use conventional modern methos for lining the walls, floor and ceiling because it is better if old buildings breath as water could build up inside. The planning people say they wouldn't mind us converting it as long as we use breathable material. Has anyone got any experience of this. Any advice gratefully received. Thanks.Tiggy :wink:]]>

			<![CDATA[Sorry for being off-topic but having spoken to the planning office I have become more confused than ever on this issue and I hope someone here can help straighten me out.<br /><br />We are building on the South coast of England. Our planning permission (won on appeal) has a condition removing the permitted development rights for extensions and outbuildings (T.&amp; C.P.Act Part1, schedule 2, Class E). There is already a shed on the site but in the wrong place, and which we had planned to  replace with a sturdier structure. The planners say that the permitted development rights (now removed) are attached to the new build, so don't exist until we have built (our local planning authority could compete with politicians for the ability not to commit themselves to a definitive reply to any question). Our architect seems to think that even with the removal of the PD rights, we would not need to ask permission to replace the shed.<br /><br />I would like to solicit informed opinions on <br />(a) whether the shed replacement would need permission,<br />(b) whether it would be best to build the shed first and then the house, or whether that would make no difference.<br /><br />Many thanks for your help and sorry again for being so far from the main subject of the forum.]]>

Part of the work included the draft proofing of all but one of our ground floor rooms (suspended timber floor) and installing UFH (Polypipe Overlay) which should be up and running tomorrow. Every room has windows fitted with at least one trickle vent (main lounge has three) and I just wondered whether these would provide sufficient ventilation for the ground floor? We are having more condensation (windows and glass panes on doors) than I remember us having prior to the work but i'm inclined at the minute to put that down all the plaster, paint, screed etc that's been slapped about the place over the past 5 weeks and my own paranoia! The new bathroom has an extractor fan but we're still using the upstairs bathroom for the time being.<br /><br />Thanks in advance :o)]]>

			<![CDATA[I am looking for a suitable software programme for installation into the heating circuits of some church premises with school rooms.<br />The building divided into five separate heating zones and I wish to be able to control the heating in each of five zones all with there own separate time schedules.<br />It would be helpful if the programme is able to record bookings for each zone (as a diary / calendar for morning, afternoon and evening use with 12 months advanced schedule of dates) and use the information to control the heating. At present I am using the Microsoft Outlook Calendar for the booking which is very user fiendly but is unable to control heating (unless you know better).<br />I would also be grateful if member has tried to obtain grants for using renewable energy for a church property if so could they advise the best approach to make and who to?  Grants seem to be available for community halls and homes etc but not churches!]]>
