Internal Insulation of Historic Buildings - Desirable but Risky

This video explains why internal insulation is a desirable but yet risky solution.
RIBuild is an EU research project that develops guidelines on how to install internal insulation in historic buildings in a moisture safe way.

We insulated all the internal faces of our external walls last spring.
They're a 9" solid wall.
The difference it has made this winter is unbelievable.
For the first time in a decade the house feels dry and stays warm after the heating has been on..

Excellent! Short and to the point. Good graphics too.

Wood fibre insulation is key, then a breathable plaster like lime.
A breathable home is a happy home

I just watched a video about the risks of exterior insulation. The main problem as I understood it was that it is difficult to completely insulate the exterior and the places that aren't insulated cause cold areas on the interior walls that cause condensation and mold. Also thermal bridging on stud walls could cause similar problems.

Great simple video. Im looking for an interior solutio for a historic 93 year old builing w/ limestone exterior building with a plaster interior and no insulation in the US. Removing the plaster on the inside is cost pronibitive.
Any suggestions???

Guys how do you find the highly performant diasen thermactive plaster to internally insulate a solid wall?

[timcarson]

How does moisture get past the acrylic paint on the sheetrock?

Historic buildings are highly likely to be 'breathable' design and construction. There is an issue, but not as intense as the above video.

Thanks for the old video but there’s better products on the market now. Closed cell foam will resolve many problems external facade can be reproduced in foam and stucco spread over can be made to appear to be brick thermal bridges can be eliminated.

Another problem with internal insulation is that it shrinks the livable space of the building,

Just let them be

[danbiss]

When you insulate the inside don't you lose the benefits of thermal mass, now requiring more cooling in the summer months. Seems like the energy efficiency gained in winter months is at least off set when now energy has to be used in the summer months for cooling when it was required before.

Insulation that is open to vapor diffusion is = to say Vapor permeable?

Hi it would be awesome if you can confirm if Rockwool a mineral wool insulation sold in USA is or can be considered as an insulation that is open to vapor diffusion? if that's the case, this will be my go to insulation behind my 100 YO double brick walls.

Thanks for takin the time to upload this very informative videos :)

If you have radiators on the same wall as the insulation is it better to bring the pipes forwards or chaste them into the insulation material (e.g. Siniat Thermal PIR Tapered Edge)? I sense it's better to have them on the outside so as not to disrupt the insulation or vapor layer.

[monicacruz]

Useful, thank you. Is there such a thing as an ecological vapor shield? I.e. non plastic? 👍👌

[Allegedlyright]

Hadrians wall in Scotland looks a bit shabby it’s only about 1600 year old and look at them tombs in Egypt still see the paint, technology we are catching up slowly

[MartinRadikov]

Excellent video. What insulation material is open for vapor diffusion though? I can only think of open cell spray foam but it is not a desired method to use IMO.

[personalexperience]

What about the use of cork as an internal insulation ? What is the best thickness/density to use for an internal wall which is set into a cutting in a hill ?

[lolamsaiprasanna]

That's really a great way of explanation.
I need help from you guys. As im doing my thesis on how to do the heat insulation in an olden brick wall building in Germany. if I get some information regarding sustainable ways of heat insulations it will be helpful for me in my thesis. that building was built-in 1929-30. so the heat insulation was not that great in that building. it is under UNESCO heritage buildings.

Great video! I am remodeling an apartment in Portugal and the wall gets so cold. Thinking of using ceramic cooating internally (via spray). I believe moisture doesn’t penetrate. Is it a common way for internal thermal insulation? How effective is it?

[rebeccaa]

Why can’t wool insulation be used internally?
