Did you know that you could be saving energy by insulating beneath your floor boards?

In this video Craig walks you through how to safely remove floor boards, fit a breathable membrane and insulation, and then re-fit the floor boards! This energy saving tip is a really useful solution which is worth considering if you’re are already lifting floor boards for another DIY project.

Great video with a lot of great info. The previous homeowner converted the garage into a living space but the floor was not insulated and the space gets super cold in the winter and stuffy warm in the summer. I really didn't want to rip up the bamboo flooring, but it is what needs to happen in order to fix what we affectionately named the "cold room." Watching you in this video gives me the confidence to finally tackle this project. I dread the winter because the room becomes unusable and it's a shame because it really is a nice room. Thank you.

Hello. Are you sure that breathable mambrane markings should be facing up? 🤔

[seanbreslin]

Excellent video, explained very clearly at different stages. Thank you

[middleagedjoe]

Brilliant content. Thanks for sharing. Really appreciated.

Simple and easy to follow, amazing, thanks!

Great video thanks for sharing your knowledge. One question, what is the reason for not laying the breathable membrane just underneath the joist as a whole? Thanks

i have a huge 5 feet deep void under my lounge floor boards so this video is ideal! I found using a multi tool plunge blade to cut the boards as the blade is only less than 1mm thick!

This looks very doable but it'll take me a long time. I imagine the space Craig does here would've taken at least 4 hours? An hour for each step - removing the boards, putting down membrane, rolling out insulation, refitting the boards. So I have a double through-lounge, I imagine it'll take me about 4 days on my own!

hang on a second! you used brand new flooring. Towards the end of the video the flooring has stickers! Great video either way!

Great video thank you. Could we have this installed on our grade 2 listed cottage? in between the timber beams and joists

Can this be done between ground floor and first floor floorboards to help dampen sound?

[AndyB]

Nice job, great energy saving tip too 👍🏻

Is the breathable membrane the correct side down allowing the moisture through and not holding around the insulation?

[claudiawainwright]

I have a EPC G with a loft conversion with no insulation. As the area is difficult to get at, cold water tank, I have been advised to use spray foam. Much controversail comments on this with mortgage brokers etc. as not being accepted. What advise please

[perryray]

Can you please explain it I was to crawl under the floor do I need membrane and how would I do it? Thx

[Wild-Storm]

is insulating the first floor (ceiling) a good idea?

[TheLife]

Can you use screws instead of shunken head nails.?
