Badly fitted insulation between joists and thermal imaging

Insulation between joists has to be fitted extremely well to make sure it performs correctly. I often see that it has been fitted with big gaps around the edges. If the insulation is not fitted tightly between the joists you will get air movement that will not help with keeping the heat in the room. New building regulations of 2022 now suggest that we tightly fit the insulation between joists this is being achieved by applying a specialised tape around the edges of the installation. However to do this not only cost a lot of money in type but also will cost a lot of money in time as it's going to be and it's a very expensive exercise. There are other installations out there in the market that are not only cheaper to buy than PIR insulation such as Kingspan but are also easier and cheaper to install. However, the thermal qualities are not quite up to the thermal qualities of a good PIR insulation. One has to work out whether it is worth buying a very high-quality insulation to be fitted between the joists and that insulation actually doesn't perform that well because of the way it has been fitted or do you buy an insulation that can be fitted between the joists that are cheaper and easier to fit but you need more depth to get to the same U-value. Using a combination of insulation between the joists and some of the new multi-foil insulation over the joist the correct U-value cannot only be achieved but also a good hair tight AVCL can be achieved at relatively low costs. One has to make sure that not only is the insulation fitted between the joists correctly but the whole room is extremely a time most people forget that airtightness is one of the most important things to achieve when insulating a house or a room. If you have got air escaping that there is probably going to be warm air and that will be replaced with cold air so controlling the movement of air is extremely important

The name of the tape mentioned above is
----- Gapotape. --------
I'm sure other tapes will become available on the market soon.
