Our newly fitted wooden sash windows have large holes around the “runner” on either side, letting in a bad draft. Also the window starts to come away from the runner as look further down. We also have newly fitted aluminium French doors, where the joins really stick out in places. Is that to be...

We are having a L shaped loft conversion done with wet, between joist, under floor heating. As we are installing carpets (2.2 combined tog) the UFH supplier warned us about heat loss with regards to warm up time performance. We have 100mm PIR everywhere, but there are lot of battens and two...

Had some more feedback else where. The combined carpet + underlay 2.0 to 2.5 guidance is based 22mm chipboard over the heat source. By using 18mm Gifafloor (fiber board) we reduced total tog by around 0.6 (0.45 tog compared to 1.05 tog). Carpet manufacture says that actually the variant of...

We have installed between joist UFH, with fibrous boards above into two bedrooms. The boards (0.4 tog) + carpet (1.6 tog) have a total tog of 2.0. We've been recommended not to go much above 2.0 and that it stops working at a tog of 2.5. So I'm thinking of either: 1) no underlay. 2) minimal...

Thanks. I discussed with builder. We agreed to 1) mortar the entire end of the exposed bricks, nothing will be removed as it might cause other problems. 2) knock in some vertical wood in the "gap" to support the horizontal support timber (don't know it's proper name). 3) remove and replace all...

I managed to get two better photos. I think the gap could be filled by just knocking in some timber support. Notice in the above photo, you can see the "west" facing supports. I do wonder if that means the problem "south" one is actually redundant? Although I would expect you would need...

Looking over the progress on our loft conversion and noticed something that concerned me. the flooring corner has two stacks of wood either side, levelling the flooring. One side is well supported on bricks, see above photo: The other left side (not visible in the above photo) seems less so...

Do you have links to the products? any you would particularly recommend? We really dislike what builder fitted, so may just pay for a refit.

We don’t want to see a plastic tube. But sounds like our only option is to replace newly fitted windows :(

Our builder just installed new wooden sash windows. We were not aware and really don't like the thick plastic spiral balance, it's as thick as my thumb with just a screw at the top to pinch it closed - very ugly. I've since read about "concealed" spiral balances, but everywhere is light on the...

I have provided a much more detailed update in this thread: https://www.diynot.com/diy/threads/how-to-strengthen-gipsum-gifafloor-flooring-joins.535869 It includes a detailed stress test report, with stress setup and results, for FHB18. Seems I will not be at risk of them breaking, just making...

I managed to find this document, which is a detailed stress test setup and results for GifaFloor FHB18 and FHB32. https://www.ribaproductselector.com/Docs/4/233054/external/COL889433.pdf It aligns with what an architect told me. That the point loads is not the point they break, but the point at...

Architect said I only needed 1.5mm, so in the end I bought this: https://www.ironmongerydirect.co.uk/product/2500mm-drilled-angle-355x355mmx15mm-galvanised-252228 Fingers crossed it's ok :)

Plumber says they cannot be easily moved, without taking it all up and damaging the spreader plates, they are nailed in hard and pinch around the pipes - i.e. it’s effectively like starting again. I have since found some angle iron steels. 25mm x 25mm x 5mm...

I need to keep the tog down, for the UFH to work with carpet. It’s why I switched from chipboard t&g to gifafloor, as it got the over all tog below 2.

Builders forgot to add perimeter support for Gypsum Fibrous flooring. I am hoping we could have heavy duty angle brackets in the gaps, from the wood above to support the edge of the flooring. The bracket would hang from the gap below the plasterboard. I’m going to need a very heavy duty and...

I opened a different thread, with a specific Q on how to mitigate the 1kn load risk. I did some calculations and it’s borderline.

Can I bond something, like steel plates, to the underside of structural 18mm Gipsum flooring g&t board joins, to strengthen the loading bearing? And will they last and be worth while? Our joists are not exact centres. The structural GifaFloor 18mm are 50% reduction in load if not supported...

Supplier came back and said we should be ok, but it has a reduced load of 50%, they only had values for FHB25 not FHB18. “The values have to be reduced by 50% if there are joints in the zone between the bearing structure. If you were using FHB 25, the attached document outlines the loadings...
