Did you end up doing this? I'm at a similar point and trying to decide if it's worth putting acoustic insulation in the attic floor joists. The attic will just be used for storage and MVHR, but maybe the insulation will prevent noise being transferred between bedrooms on the first floor over the walls?

Although my preference would be for in-roof panels and it doesn’t seem as though all the GSE landscape modules only work with panels that are max 1120mm in height. Yet all the panels I can find are 1134mm. Does seem a minefield getting everything to fit together!

What do you mean by flush? GSE don’t make in roof mounting options large enough so would have to be on rails.

Good point! That actually might be better. Foolish I didn’t think of that!

Currently researching whether it’s worth it to put solar panels on the roof on my house whilst we extend and re tile it. The height of the roof from the ridge to the rafter is ~3.6m so I don’t think I have space to put 2 rows of the most common size panels which seem to be about 1700mm tall. Is there any reason why I can’t install the larger panels that are available which seem to be ~2300mm tall so would fit better. These seem to be mainly focussed on commercial installations. example: https://www.powerland.co.uk/products/aiko-comet-1n-625w-n-type-abc-72-cell-silver-frame-gen-2

Will do! Currently just building it up on the test bench so will be a while until I can test it fully.

Was fortunate timing for me as I was just in the process of ordering a dimmer from Mike, so ordered the relay too.

Thanks all. I may not user cavity closers but instead use an airtight membrane to seal it with a j bead supporting the plasterboard. In which case i imagine that will be thin enough i don’t need to factor the membrane. I had looked at other suppliers that would do the measurement but the cost was considerably more so I decided that it was worth the saving to take that risk. I may use a professional company to take the measurements who would also be doing the install that the supplier recommended.

I’m planning on using a supply only window supplier so I need to measure the openings myself. The openings are completed in my brick and block walls but how the cavities will be closed up has not yet been decided. My expectation is that I will use cavity closers. Can I measure the opening sizes now without any closers installed? I presume the difference they make is minimal?

Interesting. I would have presumed you would do the whole thing. Does it make a difference what kind of internal wall it is? Say if it’s a cavity?

I’m surprised this isn’t higher given the clips you have on instagram of your air tightness tape detailing. Not trying to be negative and is still very good, but the other figures you have are basically passive house level. Was this intentional?

Thanks @Gus Potter Very useful. Plan for windows is triple glazed aluclad - so they will be quite heavy!

Yes it is

thanks. Will ask my SE. I think it will be a lot of weight.

Looks like this if it helps.

I’m not sure how concrete lintels would work, can you get them made to the shape of the bay? my bay design doesn’t have the brick pillars that you sometimes see, which I guess you could then use normal straight lintels.

I have 2 double height splayed bay windows that I will need to install 4 lintels. Wall construction is brick and block with 150mm cavity. Is there any suggestion on the best lintel to use? I see catnic and others can make a custom lintel to order with posts, but they seem quite expensive. There's a house being renovated on my street currently that has just used a steel plate cut to the shape, with no posts. Seems much simpler although I imagine is a significant thermal bridge.

Thanks @MikeSharp01 & @Novice Becky. Seems like the quote I have is reasonable. Realised that it specifies mastic on the outside rather than compriband so need to change that. Anyone have any thoughts on whether the industrial cling film is necessary? It’s £800 which seems like a lot to me!

Ah that’s a shame. Won’t do extensions either? I think we will end up with only 1 window being replaced in the old house then 14 in new openings in the extension.

It’s an extension and renovation. So windows into new openings in the extension then a couple of replacement windows in the old building.

On the border of Surrey and Berkshire

Fair enough. Do you have any other installers I could try to get a comparative quote from? Would prefer to have more than one and also one that’s recommended.

Resurrecting an old thread but I am similarly looking for an installer for triple glazed windows that are supply only. i have one quote for installation which is £4.8k. This is for fitting 44 m2 of Windows, the sills and cling filming them (not sure if this is necessary?) no idea if this is good value or not, seems a lot to me! @Novice Becky who did you use in the end? @craig would you share your recommendation?

Thanks all. Interesting as I thought the resounding view would be to remove it. i think I will wait to see how easy it is to excavate below. Ours is a u-shaped staircase with 3 flights (if that makes sense). It has 4 posts which I pretty sure are supporting it on the ground.

Although was just having a quick look on stairbox and a replacement staircase is ~£800. So not terrible.
