Blocks for building a single block wall
Hi,
just looked at blocks for building the single block wall for the shed/workshop and saw a very large list of options. So what would the team recommend for building a single block wall to about 2M high for a workshop 8m * 3.5m external dimensions? Do I use the old style 'breeze blocks' or can I use something with better thermal insulation? Is 100mm thick O.K. or should I go slightly thicker for more stability and better insulation? I haven't decided yet if I will render the outside, or just paint the blocks. Any advice welcome. TIA Dave R |

You certainly need something that will withstand the weather - preferably concrete-based. The lightweight thermal blocks intended for internal use would be completely useless. Have you considered hollow contrete blocks - the sort that look like a squared off figure 8 in plan view? These are wider than standard blocks, and will give greater stability. You could presumably fill them with some sort of insulating material - but you would, of course, still have a direct concrete bridge from inside to outside - so you'd probably want to dry-line it as well. Is this a free-standing building? Being under 30M^2 internal area, it is presumably outside the scope of building regs (provided you satisfy the other conditions) so you can do more or less what you like - as long as the planners are happy! How are you going to do the electrics? that's another mine-field to grapple with! -- Cheers, Roger ______ Email address maintained for newsgroup use only, and not regularly monitored..

I guess I was referring to things that look like the old style clinker blocks. There seem to be smooth blocks which have wavy lines on each side presumably for render, rough looking blocks, hollow blocks etc. Cheapest is one good option - the prices seem to range from £1 to £4 per block - I was really wondering which blocks were the best general purpose blocks. At under 30 sq m and built from blocks I should be outside both BR and planning if I get my design right. I was wondering about the benefits (if any) of thicker blocks or hollow blocks. With hollow blocks it must be interesting to get mortar on them without filling up the holes in the middle (which I presume are for insulation). |

With hollow blocks it must be interesting to get mortar on them without filling up the holes in the middle (which I presume are for insulation). I've seen some interlocking "terracotta" looking blocks in France that supposedly have very high insulation qualities and use the thin joint system (an applicator that rolls a layer a few millimetres thick and you just plonk the blocks on). They're intended to be rendered. I seem to remember that they're pricey though Ah, found them: http://www.clayblocks.co.uk/ and http://www.tackburn.co.uk/ SteveW |

The cheapest - seriously, which will be hollow clinker (concrete) which have very little U value - those that do are more expensive, (thermalite) and these are the ones with the wavy lines - they're not suitable for outside. At under 30 sq m and built from blocks I should be outside both BR and planning if I get my design right. I was wondering about the benefits (if any) of thicker blocks or hollow blocks. practically none insulation-wise, but it may get you slightly more stability, although I presume you'll be doing pillars halfway along each long wall? With hollow blocks it must be interesting to get mortar on them without filling up the holes in the middle (which I presume are for insulation). no, they're there for the same reason as holes in bricks are there - to save materials, but unlike bricks, the holes don't go all the way through, the tops of the blocks are solid, and they are laid hole-side down -- Phil L RSRL Tipster Of The Year 2008 |
