Just started watching the following video, where it is claimed that the plastic bit in the string of pull cord switches is for insulation purposes and thus is a safety device. I can understand this if true, although is new news to me. Any truth to this, have you heard this before, and is there...

Dear all, First timer here, really impressed with the wealth of knowledge here and hopefully someone can help me too. I have basic DIY knowledge and have been experimenting/learning on my own house since 2016. We live in an old house that has 20cm exterior polystyrene insulation all around it...

I just bought my first flat, the building was originally a single storey with ridged dormer windows to the front. Not sure when it was split into 2 properties or when the flat roofed dormer went in at the back. I was removing plasterboard to put in a shower and found a low stone wall, covered in...

Hi I am looking to get some injectable foam insulation for a flat roof celling that has some spaces in the existing insulation. I am aware that you can buy big kits that you might use to fill up large spaces like a wall or something. However I just need a small amount for some gaps in the...

I`m doing a bit or renovation and I have 100mm of concrete sitting directly on soil. Removing it to poor a proper concrete and then 200mm insulation would have a massive cost impact and this is not feasible. I was thinking to poor 30mm or screed to level up all ground floor and then 18mm floor...

Coming to the problem fresh, I imagined that there will be a 'sweet spot' for insulation sizing for each size of pipe and for each ΔT that reflects the law of diminishing returns. Has anyone already done calculations on heat losses that can validate or refute my approach to this? Using the...
