Hi, I’m in the latter stage of finishing a new roof. I could use some advice on insulation and cavity size. I am able to get 150mm of insulation between the rafters and then plaster board, leaving a 25mm air cavity. My questions are: Will this be ok from a building regs point of view? Will it be sufficiently thermally effective? Any thoughts please? Thanks v m,

Hi, I'm doing a major refurb and switching to an ASHP. I've insulated the walls to within an inch of their lives but now just getting the new roof felt & battened. I need to insulate the crawl spaces in the loft area and now is the time where I have the best access. I have removed all the old fibreglass insulation and want to replace with something that is thermally efficient and won't cause me to itch as much as the fibre glass. What would people recommend that is efficient and easy to install. What depth of insulation should I be aiming for in the loft spaces? Any help much appreciated. Thanks, W

Hi, Thanks for the suggestion but as the areas are a series of small-ish spaces I might not get the heat output that will be needed? Appreciate that I don't need the utility room etc to be roasting but think a series of short runs might not be terribly effective? Thx W

Hi all, I am doing a major refurb and had planned to use wet underfloor heating to the new build kitchen / sitting / dining area. I've factored in floor height to accommodate this. On reflection, I think it would be great to extend the underfloor to the adjacent utility, bathroom and hall areas. The problem is that this area is existing and is a timber board floor. I'm reluctant to have to make major alterations to the floor height in this area - but it would be great to avoid using radiators. I understand there are mesh type / thin profile electric underfloor systems - which would minimise the extra work and hassle. My questions are: Is electric underfloor reasonably economical to run (we'll have solar and battery etc) These areas will need background warmth only. Are the mesh / thin profile systems an option for this type of application? Is the existing floor board floor a problem - what would I need to do to this to make the approach effective? I'd really appreciate some help with this - really outside my comfort zone. Thanks, Sean

Hi, Does anyone have any experience of True Glide based in Sheffield. I've been impressed with the quote and service so far - but would like to know if anyone has used them and would recommend them please? Thanks W

Thx - I'll look them up!

Hi all, Does anyone have any experience of QTD timber in Reading? I've got some sample of their heat treated cladding which I like, but I'd like to know if anyone has any experience / knowledge of the company and theirproducts please? Thanks for your help, W

Hi, Does anyone have any direct experience of Cortizo windows and doors? I have a good quote for supply but would be more comfortable if I had some feedback from you wise people? Thanks, W

Hi, I'm planning and refurb and was thinking about building an external 'services' cupboard to house electricity meter, solar controls and battery. The plan is to build a timber double skinned fully insulated (50mm PIR board) cupboard which will then be clad in timber. If I have the battery sitting in there - am I likely to run into any little nasties that will come to bite me? Thanks for your help, W

Hi, I'd like to get some recommendations for a good supplier installer in the South West (I'm in West Somerset). Ideally a supplier that can design, supply and install solar and and ASHP. I'd be grateful for any recommendation please? Thanks W

Hi, Quite a few places advertise it but when you get as far as placing an order they can't fulfill. I have got a couple of places that do seem to be able to supply - but I suppose I won't really know until order is placed. I'm looking at the beads option too.

Hi, I have 120mm Kingspan K108 specified as the cavity insulation for a new extension as part of a renovation. I'm keen to insulate really well but understand that the 120mm Kingspan is now subject to a minimum order of 1000m2 - which is bonkers! I'd like to maintain the designed thermal properties - so my question is: Can I double up and use Kingspan 60mm boards? I'm guessing that this will give a very similar level of insulation but wonder if having two boards will create other issues such as creating a draft chimney within the void or similar? Would it be any more of a pain to install than single board etc? Are there alternatives that will have the same thermal properties of the Kingspan? Would really appreciate some help with this! Thanks in advance! W

Hi, Does anyone have any experience of Ideal brand heat pumps? A supplier has proposed this brand but it's not one that I have come across (but then I'm new to this!). Really grateful to learn if this is a reputable, reliable brand that is efficient etc? Any input very gratefully received. Thanks, W

Hi, Would appreciate any thoughts on ASHP's and noise? The ideal location would be at the side of the house but this borders our neighbours. Do I need to be concerned about noise potentially being an issue for us and our neighbours. Luckily, the neighbours are great and so keen not to hack them off more than we have to. Any advice gratefully received! Thx

Hi all, I'd appreciate some advice on whether there is any value in having a battery as a part of my solar set-up? We have a relatively small roof footprint and so we can only generate approx 3.6KW from solar. I had originally intended to have a battery but have been advised that it is unlikely to be very effective given the 3.6KW constraint. I don't want to go to the expense and hassle of installing a battery if I could use that investment better elsewhere. Can anyone help me with this please? Thanks in advance, W
