External insulated cladding.

We have a 1960’s two story extension, made from a rubbish looking brick that matches nothing in the area. We want to clad it, as well as insulate it. The flat roof above is being done so we can increase the over hang.
Has anyone any experience in such things and can offer any advice?
Thinking wood or composite cladding.
I’m in Oxfordshire.
Cheers

I can’t offer that much advice other than to remember that cladding is effectively a rainscreen, so it doesn’t have to be all that solid. I say that because you might find alu cladding cheaper and easier to work with than wood/composite and wont warp/rot. I had it on my old house and it looked genuinely new england style while needing just a clean every few years, never any maintenance.

If you are doing it, consider a directly mounted flat-backed gutter with flashing coming down from the flat roof into the gutter, this will prevent water getting down the back of the cladded section from the top.

Not sure if same as you are thinking but we (Housing Association) have been insulating hundreds of our homes with external wall insulation (to meet Scottish regs). It’s like a 100mm thick rigid sheeting but it gets rendered externally for finish (this is west Scotland so render is a common finish type).

I can ask our Asset team questions if that is what you are thinking.

Out of interest, how do you deal with partially owned properties. Ie we own the ground floor flat and the upstairs is HA. The housing association has done some comedy “this is far as we go” on some things even on shared areas.

The easiest way is for the contractor to make the private owner an offer to do the works for a bargain price that they are unlikely not to take up.  Usually works and is worth it to the contractor to take the hit to avoid access issues/complaints from potentially disgruntled owners.

vmgscot thanks but I was thinking more of an ready made bolt on solution.
BP I do like the look of aluminium I’ll check it out.

As @perchypanther says – a discounted offer is usually made to private owners by contractor but not everybody can afford this.

However, we (in Scotland) are required by Scottish Government to meet their regs so work gets done on the HA properties – sometimes resulting in the patchwork look.

They’ve only just got round to finished the cavity insulation round here so i imagine i am a long way off the offer of cheap external.

It can be quite frustrating though they never bloody ask to share the cost or even inform me of work being done so random stuff gets done.

I once woke up having got back in the dark to find 3 story scaffolding in my garden 😀 and bits and bobs ripped up and moved about.

If it is a cavity wall it needs to be full filled to get any benefit from external insulation. External insulation then rain screen cladding is a good way to go but requires good detailing around openings and really should be detailed to cover the slab edge(below dpc) to prevent thermal bridging. Internal ventilation should always be assessed before insulating. Correctly working extract fans and trickle vents etc.

I fancied wood cladding but a near neighbour did it 2 years ago.  Looked really good for about 6 months, now it’s badly weathered and when wet looks awful.

Everyone else has gone down the k rend route but I don’t like it.  I saw a nice house in the lakes last week with just bare unpainted smooth concrete.

On my planning permission the architect specified new render to be like existing, I actually asked him if I had a choice and he said yes.  So check your planning.
