I am in the last year of completing our retirement bungalow doing 85% myself.

I have a query that's worth asking others on floor air leakage.

Floor is block beam then 100mm insulation, with underfloor heating clipped to that then 60mm screed.

Edges of floor had 25mm insulation as cold bridge plus a thin sponge type membrane for screed to expand.

All walls external and internal are therms with dot dab plasterboard then skimmed.

 

At the base where the plastered wall meets the floor you can see the 25mm insulation.

Before I tile any floor and then fit skirting, is it worth putting an AirStop type tape all around the base of wall to floor.

If so  what product could I use that's good value as there is a big difference in cost between a roll of ISO Ltd AirStop and good old Gaffer Tape.

 

Feedback welcome

Gaffer tape is not something I would suggest using in my retirement bungalow - nor in any home as a primary air barrier

 

I’d use low expanding foam and wedge the skirting well so it both grips the skirts and fills all the gaps. Will also stop air down the back of the dot & dab
