Solid Wall Insulation - Thermal Plaster

[Sacrid]

Hi Guys,

Just started to renovate and 1890 Victorian semi-detached house and wanted peoples advice.

I want to improve the thermal performance of the walls by insulating.
The outside cannot be insulated as it will ruin the look of the property and secondly cost me a second mortgage.

Therefore my only option is to insulate the internal walls either with thermal lime based plaster or insulating plasterboard.

I not to keen on plaster boarding as it seems I am not being faithful to the building so I am exploring the thermal cork lime plaster.

The intention is to take all the exterior walls back to brick, as some of the plaster has blown, and then be plaster. I have been informed that to get a finish of a standard plaster I need to apply 3 types.

Anyway I was wondering if any has any experience of the two types of plaster systems that I am considering using.

1. Diathonite - Newton Membranes
2. Secil EcoCork Lime - Insulating Lightweight Render - Ty Maur

Thanks in advance for any advice given.

Hi there, I'm just at the point of choosing what to internally insulate my solid walls - wondered what you went for and how it's working?
cheers, Stephen

...just a little update on the topic - I'm currently putting Ty Mawr lime hemp plaster on the walls, and I have to say it's a bit of work to knock up by hand, and I'm giving the wall a lot of water mists before, and repeatedly after putting it on, but it's lovely stuff to work with - nice and squidgy and sticky, lots of time to play with, but is also going off well on the walls with very good adhesion and no cracking. I might play with mixing lime putty with hemp horse bedding for the next layer...
