Hey group, I have been upto my site and noticed some damaged insulation and some not fitted correctly (in my opinion) im pretty sure its a slight problem but wanted to know opinions before i speak to builder, please see attached photos and give me your opinion. I can also say its being lined with vc foil then 30mm kingspan before sheeted in etc. Thanks in advance.

hi Steamy, thanks - ours lucky enough is no were near as bad as that!!

Hello group, got a question im hoping someone can answer? we are having our house built, basically they are building the kit on site and erecting - were about 80% of the way to being wind and water tight - last week when i was up i noticed little bits of mould appearing on the plywood of the kit and also the roof truss's etc are all SOAKING, (yes i know it is middle-end of October), im just really wondering if it will be ok? or once were wind and water tight do we need a few weeks of a hot air blower in the place or what? last thing i want is to be insulating over mold or not giving adequate time to dry out, my builder said it would be fine (of course he will say that), i was debating if i get a building surveyor out for a look and get his opinion. Thanks, Mike

before i put too much effort in i wanted to get the green light from the council. and if being honest thought it wouldnt be a problem considering there all hampering on about the enviroment etc etc.

would it look too busy with the velux's??

i have about 10 velux as my upstairs windows. i have not yet spoke to the planner that is what im going to do this week try myself to speak to him its all went through my architect up to now.

Hi Ian, we wanted the in roof system. so it would mean lifting slates to put in, its borderline ridiculous lol

Hello, We have full planning for our house but have thought in recent weeks we want to add solar PV, but our architect has approached the planner and hes being awkward saying the roof will be too busy with solar panels.so basically its a no. We feel hes being super awkward as once the house is built we can put panels on without planning anyway.... the council are always pushing renewables around here but making it super hard to have them!! Any advice?

Hi Barry, How much were you ? and what sort of system do you have?

Hello, Looking at getting PV added to my self build, just wondering has anyone heard of Viridian solar panels? and if so any feedback? Thanks, Mike

i get the idea, likely solar power at 4kw is ok idea but anything above is going to need more permissions and a battery is 100% no go! i think im going to go with a 4kw system 8 if i can get permission and leave the battery to another time when there more efficient or better priced etc.

From what im led to believe the seg ranges from 1.5p to 11p depending on who you chose to export to so on average they say 5p per kwh.

yeah 100% something to look out for, the msc seems a rip off lol 5p for a unit of electricity who cares..

hence why i was looking at batterys and i could put into the calculation im saving the 20p i would be using from the grid to the battery but like previously said in the winter months the battery would almost be obsolete. i will need to do a calculation and see if its worth it, sounds great doesnt it in the summer banking 10kwh or energy during the day for nighttime cooking etc is all free, the house im building is going to be all electric anyway due to location.

Thanks for all your help guys and gals in this group, i have one final question, its more of a yes that sounds feasible or no your way off.... i have worked out that 8kw solar system would be around £8k I have also put this into the JRC Photovoltaic geographical spreadsheet i was offered at the start of the thread now - assuming £8k for the 8kw system and the 8kw system produces 7200kwh of energy a year.... (According to the spreadsheet) assuming i used 50% on home energy and 50% went to the grid that would be 50% at home energy saving me £0.20p per kw (3600 x 0.20p = £720) 50% sell to grid for a measly but still something 0.05p per kw (3600 x 0.05p = £120) total saving hopefully of around £900 per year, now on a outlay of £8k it would take roughly 9 years to make that money back.... bearing in mind the 0.05p doesn't go down and the cost of Electricity stays the same. What do you all think? does this seem ok or have i messed up some calculation ( Be kind) haha

i found a snippet from the building warrant looks legit enough 50 x 38 treated limber horizontal framing at not more than 600 mm centers on 50 x 50 treated limber vertical framing at centers to suit kit framing fixed through dpc over Protect TF200 Thermo breathable membrane on 10 mm thick sheathing ply on 140 x 45 timber framing

good bad? normal, not normal?

unsure thickness. were would i find out if it was authorised from the engineer? would that be on building warrant?

im assuming this is not OSB? looks like ply now i see it

i agree, i was in a fortunate position i suppose that i had a main builder who subbied the job out a mcs accredited heating engineering firm, they came back as 12kw but i fell out with that builder and we now have a new builder who is in fact a heating engineer to trade and i think he said 12kw or 14kw i cant remember exactly. so what im saying is having 2 comparable quotes makes me feel at ease, if one guy tol me a 6kw and the other said 12kw i would be a bit worried.

ok thanks SteamyTea, i imagine it would be as the builder is good and came highly recommended.

the company owner i think is a plumber to trade and there also MCS registered (Probably does not mean f all lol ) but he has sized it at i think 12 or 14kw ashp and 300l tank. i do remember him saying to me he over specs so its not running close to its limits. (something along the lines of that)

i will try get some pictures this evening, but im pretty sure now i think about it its not OSB so likely plywood or similar is this ok, in the groups opinion ?
