Attach render to bring in line with extension.

[kliovance]

Hi ,
Have built extension to property with no cavity in the top 4ft, so steps in just over 2" from extension. Architect recommends insulating from the exterior to bring in line with new build and then completely render. Have been told this will blow even with stainless steel lathing.
What would be the best way to bring the top 4ft of the existing property property out, so it is in line with the extension for rendering?
We will then insulate internally. Any help/suggestions would be much appreciated. Thanks!

why have you created a new building line so far back from the existing?

2 feet is an awful lot to make up. wouldn't it have been simpler to start the masonry the thickness of render back from the existing, building it with a cavity type twin skin jobby?

what makes you think stainless e.m.l and render will blow in any case?

Hi, It's 2 inches not 2 feet. We have been advised by our architect to attach celotex insulation between batterns. Then stainless steel lathing. We have consulted 3 local renderers and they have all said it will blow. So need to bring out the existing house by 2 inches so we can then render. Any ideas??????

doh! 2 feet my a**e!

sorry about the misread. lots of pre-fabricated buildings are successfully rendered and insulated this way, no probs. take a look at this thread and the photos.//www.diynot.com/forums/viewtopic.php?t=83059&highlight=lintel

Hi Noseall, thats really helpful, if this is so successful why do the renderers we have spoken to say it will blow?

If we decide to go with internal insulation what would be the procedure? Can we add over 2 inches of render to the building? Will this work?

Thanks for all help/advice it is very much appreciated.
