- 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.
Let us know how you get on in the comments.

Simple and easy to follow, amazing, thanks!
Glad it was helpful!
That was really helpful craig. 👍
Glad it helped
Always well presented and well filmed. Nice one.
Cheers, glad you enjoyed it! More on the way
Thanks Chris! Much appreciated.
Nice job, great energy saving tip too 👍🏻
Thanks! 👍
Thanks Andy! Yes I know, so much heat gets lost this way!
Great job
Thanks!
Great job and video
Thanks!
Brilliant content. Thanks for sharing. Really appreciated.
Glad it was helpful!
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.
Good luck with the "Cold Room" Let us know how you get on
Great video thank you. Could we have this installed on our grade 2 listed cottage? in between the timber beams and joists
Excellent video, explained very clearly at different stages. Thank you
Glad it was helpful!
Many thanks
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!
Hello. Are you sure that breathable mambrane markings should be facing up? 🤔
Is the breathable membrane the correct side down allowing the moisture through and not holding around the insulation?
Do i lay the insulation to the same depth of my joists? regardless if i have a 5feet depth void underneath??
Would this help with heat coming from radiator pipes that heat my bed up?
Can’t help think Red Dwarf, love this guy 👍
Can't tell if that was sarcasm lol. Different Craig from Liverpool!
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!
Great tip! Thanks!
Did u lift all the floor ? Or just crawl underneath and stuff in the insulation and then hold in place with the vapour barrier?
Cheers
Can I use any loft mineral wool? I am in the process of doing my dads house which is 1930s
Thanks
No problem, hope it helped!
hang on a second! you used brand new flooring. Towards the end of the video the flooring has stickers! Great video either way!
What do I do if I got pipes and cables everywhere?
Loving the constant mixing of metric and imperial.
5 feet 6 and 3 mm.....Englishmen of a certain age. If you know, you know😂😉

Can you attach it all from underneath if you have the crawl space? Or is this designed to allow the timbers to breathe more as the insulation doesn’t touch them?
Thanks great video
The insulation touches the floor boards though.
Can you please explain it I was to crawl under the floor do I need membrane and how would I do it? Thx
Use metal strip banding and pin to underneath joists like i did! Much easier, quicker and cheaper
Hello, can I use Fakro breathable membrane? Green side up?
It doesn't have to be breathable membrane to hold the insulation in place. I used a 100m roll of metal banding that is normally used to hold conduit in place against walls. i pinned it to the underside of the joists every 300mm apart and it worked a treat!
If I am insulating between joists from below can I tack some breathable membrane to the underside of the joists to help prevent cold drafts coming up through?
Yes mate, thats even better if you can climb down underneath! Watch out for creepy crawlies tho! 🕷️ 🕷️🕷️🕷️😊
Any reason why you don't wanna lift the floor boards??
Does the membrane serve a purpose or is it purely just to hold the mineral wool in place?
There would normally be a cavity under the floorboard, so yes, the membrane is there to hold the insulation in place
is insulating the first floor (ceiling) a good idea?
I wouldn't think there'd be much point in that as it would just be insulating the upstairs rooms from downstairs. This is all about trapping heat inside the home.
Hiya, I've been told putting a membrane on the cold side (underneath) will create condensation against the insulation. It should be on the top. What is the rational for doing it here? Are there differences i need to know about? Thanks in advance.
You’re thinking of a vapour control layer rather than a breather membrane. Vapour control layers go on the warm side of the insulation and breather membranes on the cold side. Although I’m not sure why he’s using a breather membrane on a suspended floor it’s unusual. I suspect maybe just for something to use to hold the insulation up and maybe reducing droughts.
Genuine question: doesn’t the insulation roll that goes underneath your carpet do near enough the same thing?
Hi mate, so underlay is mainly to give your floor a base, although certain kinds can give you insulation, but nowhere near the amount of heat will escape if you have proper insulation in between your floor boards like the one in the video. Hope that helps!
@@MrandMrsDIY - Nice one!
@@Station9.75 No probs!
that's called underlay
Is wool insulation better than the board insulation?
Wool is much cheaper and easier to lay, board does have better insulation though
@@SilverlineToolsTV can we use rockwool slabs as well? Looking to take on this project in the near future
Hi - can i do this in the bedroom and attic floors as well without any issues? The entire house is freezing in the winter so thinking I'll do every room, ine at a time - thanks
I did exactly this 18 months ago. It helps to keep the heat in each room, which is really helpful if you only heat rooms you are using.
@@gracegarner4629 thanks for your message - did you use this method with the breathable membrane in the upper floors as well?
@@PapiQaz I didn't. Membrane is used under the ground floor to hold the insulation in place only, but whatever is used needs to be breathable (I have netting under my ground floor so most of the insulation is exposed). You don't need to use a membrane upstairs because your ceiling does the holding and it's breathable. I hope that makes sense, basically just lift the boards and lay the material like you would in the loft.
@@gracegarner4629 awesome - thank you very much for replying :)
@@gracegarner4629I didnt use the membrane, even on the ground floor! i used metal banding pinned to under the joists and used them every 300mm apart to hold up the insulation
Where is the membrane from??
We used a roofing membrane/ breathable felt from Homebase
Um, did he not forget vapour barrier?
Arguable. Craig does state why i.e. breathable. Especially in the loft.
No, not if air bricks are fitted underneath the joists
Watching this clown trying to prise up a floorboard that he is actually kneeling on, priceless.
Yes then Craig lad great idea 🪚👖👊
He knows his stuff!
Thanks mate!
