Thank you, I will look into them What about the warm wall method? 50mm PIR, then 25mm studs with a fixing through the battens and PIR? What fixings would be best to fix through them both? Would I then install cables and pipe work the warm/room side? In the 25mm void? Thanks again

I can definitely mention the 200mm PIR instead of the 150mm originally the building said 100mm but I upped him to 150. good idea regarding the additional PIR in the vaulted ceiling bedrooms I will be definitely be doing that. Regarding the insulated backed plasterboard, do you think this will give better performance than say a stud wall infront of the walls with an 10mm air gap and 50mm rock wool insulation? thanks again

Thanks for the reply Regarding insulation, there will be 150mm under the UFH in our new ground floor slab, the existing building has 70-80mm cavity with insulation in and I will be insulating internally using either 50mm PIR or rock wool depending on what system we install (recommendations welcome!) also in the bedrooms with vaulted ceilings will be 100mm PIR between the joists. windows are residence 7 You mentioned air tightness, what are the best ways to achieve this? we want a couple of log burners in kitchen/diner and lounge…are these Ok for air tightness? Many Thanks

Hi All We are planning our renovation project for this year, our village doesn't have mains gas We think we have decided to go for ASHP (16.5kw Daikin Altherma) to supply our heating/DHW..so solely electric rather than LPG or Oil The way our house faces, with very small section south facing and blocked by tree so I don't think it will be very suitable for solar panels (see picture) Would people still look into solar panel and maybe have a company come round before ruling it out? Is there any other options to help reduce energy costs? I'm guessing only battery storage is useful when having some solar panels (or another form of generation) All advice and information appreciated Many Thanks

So fixed 50mm pir directly to the wall? Tape them together? how would I attach the plasterboards? Sorry for the daft questions

Thanks, this was my original thought with 50mm studs. How does rock wool compare to PIR in terms of insulation? Im guess rock wool a lot easier to use/install?

Hi all With our build in its planning stage just trying to sort some finer details. Our existing bungalow only has a 70-80mm cavity (blown insulation in it I believe) we are going to insulate internally what would people use to insulate inside? 50mm celotex or 50mm rock wool? what is the best method to install it? New metal stud inside? Battens? All advice greatly welcomed as I am struggling for the best way to do this at the minute Many Thanks

Thank you very much for the comments I will definitely be recycling them now, I can use them as oversite before the builders create our new concrete slab Currently the bungalow has 700-1000mm void under the floorboards and the plan is to have a new slab throughout with insulation, UFH pips etc Would you recommend hiring a crusher for a few days or would breaking them up with a sledgehammer be ok? I'm guessing the crusher will save a lot of time!

I had it in my head that you couldn't use hardcore recycled from your site for a concrete slab base (for the house) as it would be classed as ungraded I might be completely wrong though

Hi Early next year we are planning to be removing a couple of garden walls and also some internal walls of our bungalow ready for our extension We will have quite a few tonnes of brick waste Are we ok to fill a skip with the waste? Or I don't mind doing trips to a tip over a few months? One other option would be to hire a crusher but we are not keen on using 'recycled' hardcore as part of our new concrete slab Just wondered how people managed to dispose of their waste bricks/concrete Many Thanks

Hi Kernow I am also looking installing R7 windows in our project Did you go with them in the end? Has anybody else got any feedback/reviews on them? Many Thanks

Unfortunately it is not a great plot for PV. The back is NW facing and the left had side of the plot is tree lined I will be installing an ASHP so its shame its not the best to install PV

Hi All We have just had the nod from planning so we are now getting the structural engineer involved and he has raised an with the roof with I didn't realise (naively) Basically he is saying if we built it to the drawings currently it would have a flat roof section I have attached a marked up section of the roof he has done and also 3D renders to show what we are hoping to achieve. We are still undecided on the vaulted ceilings in the bedrooms and landing so could do away with Velux windows He said I have 4 options: 1. to have a 3rd gable over the porch with 2 ‘captive’ gutters running between the 3 gables but no flat bit. 2. Smaller flat roof in the centre of the roof (not accessible and leak problems) 3. Raise the ridge so it sits centrally from side to side but this will create a high ridge that the planners may not like and will make the whole property much taller and ‘imposing’. No flat sections. 4. Large flat area that is accessible and can be drained (as my sketch). Option 4 says large flat area to be accessible? How would people do this and drain it? Has any body came across and sorted this issue before? Any ideas/opinions at all? We have a month or so to make any alterations to design so would like to get this bottomed out Thanks again SE Roof Mark-up.pdf

Hi Our plans are almost decided, one of the final things that have came up is bay window roof types. The architect has put flat ones on Has anyone got any experience with flat roofs on bay windows, can you get one piece composite roofs? rather than it being made up of strips of roof material? Or do we go with the traditional pitched roofs? Thanks in advance

Yes basically radiators with a fan, my concern is are they noisy? Been having a look but can't see much on them regarding reviews etc

We are having UFH throughout the ground floor, then upstairs in both the bathrooms Due to having 22mm T&G flooring and carpets upstairs we wasn't sure how effective UFH would be and the additional cost of insulating underneath so we thought UFH downstairs and then rads upstairs could be a good option. Then the guy recommended having HPC's instead of traditional radiators

I'm guessing what they mean by 'cooling' is being able to use the fan element of the convector to blow cooler air into the room

Hi I have been spec'd a 16kw Daikin Altherma 3 with outdoor and indoor unit (possibly combine hot water tank unit) The guy also said Daikin do heat pump convectors instead of radiators and supposedly work better at lower temperatures than traditional (low temp) rads do. They also claim to offer heating and cooling Has anyone any experience with these? My mrs won't be happy with the look (i'm sure) but the positives might out way the negatives All help and advice/input greatly appreciated

Thank you

Hi We are renovating a bungalow and just starting to get down to some finer details regarding insulation. Obviously I would like to insulate the property as well as I can. Exterior insulation is not possible in our design, so we are planning to install 50mm PIR on the internal walls, however the cavity between the bricks is only 70-80mm and I'm almost certain there is some form of blown insulation in there (I could see some white fluffy insulation when I took a window board off) My question is how effective is this insulation? Is there a way of improving this insulation further during the build? Many Thanks

Hi The supply cable to our bungalow comes in the front side of the house and then into the garage, I am happy with the location of the incoming cable to the property I don't know the exact route it comes but it looks like it could cut over where I am planning to have a double story extension. Can I build over this cable or would I have to re route this cable? Also the cable comes up the front of the bungalow, am I ok to plasterboard over to conceal it (obviously keep it within cable zones) I am not sure what to do on this so any advice would be helpful Thanks again

Hi We have just had our planning permission granted (subject to Bat survey) A couple of builders whos been the quote our extension/conversion has suggested have building regs drawings with structural calcs on etc... Has any one used an online service provider of this? Just send them the drawings and they produce them? Any opinions on this? How has other people approached this?

Hi We are currently in process of planning our extension/renovation We are looking to install a 16kW ASHP, electric range cooker and all the other general electrics within a house (as this minute no electric showers) A builder mentioned I might need to look at the supply to my house to make sure it is 'man enough' to cope with the extra demand Is this something people have come across before? Many Thanks

Thanks for replies, basically we 'just want it' we like the idea of no radiators in any of the rooms especially if go down the ASHP route as they would need to be oversized. We like the idea of engineered wood flooring throughout upstairs (at the minute) My concern is would it work if we have UFH pipes, then 22 T&G flooring and then 20mm engineered wood floor? How much insulation would we need in between the joists - is 50mm PIR sufficient? This will be a full house and not a chalet/dormer style bungalow so will have full insulation in the loft Is there a better way to achieve this? Thanks again

We have decided to have UFH upstairs in our bungalow conversion As this is a conversion it will have complete new joists etc so can access from either above all below The UFH company priced (warmup) to supply aluminium diffuser plates to install it upstairs Is this the best way to install UFH upstairs? I am guessing I will need to insulate below these plates, does this have to be pir or can it be standard rockwool type? We are thinking of having oak/engineered wood floor upstairs and tiles in the bathrooms (2) What is the best way to achieve this floor look? Do I lay 22mm T&G floorboards over it and then my floor covering? All help and advice very much appreciated
