External Wall Insulation

Hello,
My property is semi detached in Birmingham.
I am confused, does planning permission required for external Wall Insulation? It's not listed property and not in conservative area.
On my road none of the properties are rendered so if apply external Wall and rendered will that need planning?
I am aware building regulations are required.
Thanks
MS

If the materials used change the external appearance of the property, then PP may be required - Best to give your local council a call.Do give thought to the detailing especially if you have bay windows or a limited overhang of the roof. A few of the 1920/30s properties had EWI done under the old Green Deal scheme (the one where you repaid the loan as part of your energy bill). In my opinion, they all look piggin' ugly for having the work done... I'm for internal wall insulation as it is easier to DIY and doesn't affect the external appearance. Downside is a slight loss of floor space, but does give one the opportunity to redecorate.Her courage will change the world.

Rosa_Damascena said: To redress the balance, I had external insulation and silicone render at 100mm thickness in total and it does the job and looks good too. Its not something I shall be looking to repeat for the next 30 years.If done well, and attention is paid to the finishing detail, it is good. But it does have to be done right, and doesn't suit every property.Her courage will change the world.

CAVITY or NOT. If your walls have a cavity, EWI is a waste of money. Why heat up the cavity ???? If other homes are rendered go ahead

(Small brain, easily confused- but I need to know before my external walls go up).

An external wall doesn't have to be a cavity wall. It has to meet the regs and the most popular way with masonry is the cavity wall with part or full fill insulation. Solid walls like this are not so popular on new buildsH+H | External Walls: Solid Wall Construction (hhcelcon.co.uk)1

2 Cavity wall, retrofitted with blown in insulation, it's efficient but you have lost the cavity, so if any water gets in from the outer leaf of blocks or bricks it will go through to the inside. also can be tricky to get everywhere full of insulation, sometimes they miss bits when blowing it in.
3 cavity wall, clad with external insulation. this is more expensive, and with an open cavity you'll still be safe from damp bridging the cavity, but it's not as efficient, if the cavity is well ventilated the draughts can take a lot of the heat away
4 cavity wall, clad with internal insulation. problem is you lose floor space. and fixing to the walls becomes harder but it's probably the most efficient solution in terms of heat loss and maintaining an open cavity to stop damp getting in
thats my basic thoughts on it, probably even more variables with different types of construction and insulation0 -

If other homes are rendered go aheadbrick+cavity+brick+insulationinsulation+brick+cavity+brickThe order you follow when adding numbers (thermal resistances) doesn't matter. The only restriction is that the cavity can't be the first and the last.

They will probably do a cavity wall, which could be either full or part fill. Full could be batts or boards, part fill boards fixed to the inner skin.0 -
