So the weekend has come around again, and this is my chance to update this blog and let you know where we have got to so far.
At last we begin to actually make things this week (rather than just demolishing them!) 😆
We have lifted the floor as you all know and we have found a really neat product called Insumate which we are going to use in a slightly different way to the way it was designed… as are going to suspend Earthwool (recycled glass bottles) insulation between the sleeper walls on a netting (that we bought from a garden centre up the road) and then also use Earthwool between the joists, we will then use the Insumate to act as the support for the underfloor heating.
So, we have run the netting over the whole stretch, using celotex either side of the sleeper walls to ensure that the netting doesn’t bow in the middle.
This way it remains a continuous line of insulation (as much as possible) under the joists and then also between the joists.
This ultimately gives the floor a U value of just 0.16W/m2K (for an explanation of U values click here) which is significantly better than building regulation 2010 standards.
So, Simon and Gaz (seen in the pic on the left) have worked away like busy beavers not only to lift the floor, but then to return it back to an even better state than it was originally. It’s quite difficult to show in these little photos, but it really is a thing of beauty. The credit has to go to Fran for the concept and the fellas for doing such a great job and really taking pride in what they do.
We also insulated the base of all of the exterior walls, used some MVHR ventilation to maintain the ventilation from the air-bricks for under the floor.
This was then fixed to the airbrick with expanding foam – difficult to show in these pictures but it was a great idea… and works really well.
Another example of re-using a product not necessarily for its original use, but adapted for a new use. Which reminds me, we were also using particular fixings to hold the celotex to the sleeper walls and then we ran out.
So I was sent off to find some – and couldn’t anywhere… but Gaz took up the challenge and came up with a great idea – just using some of the offcuts from the Insummate to act as the fixings meant we saved £50 (+vat) from the budget. More environmentally friendly and also cheaper… just what we like.
Just to finish off (basically because i’m a little bored of myself droning on) we also got the plumbing first fix and the electrical first stage sorted out as well…
Keith and Marcus busy setting up all of the services that will ultimately make the building work as a home.
