ᐅ Insulation – External Thermal Insulation Composite System (ETICS) – using Multipor
Created on: 12 Oct 2016 10:27

thib01My house is going to get an external thermal insulation composite system (ETICS). The area to be insulated is 210 m² (2,260 ft²). The walls are made of masonry Poroton blocks, 36.5 cm (14 inches) thick, built in 1989. I have ruled out polystyrene and mineral wool. Multipor would be an ideal solution for me.
I want to buy the material myself and then have it installed. The price for the material (Multipor boards 120 mm (4.7 inches), plaster, paint, adhesive, mesh, trims—all from Multipor-Ytong) is €57 per m² plus VAT.
Here is my main question: who has experience with Multipor as an ETICS or who knows this material? Is it easy to work with? Thank you for any answers.
Kind regards,
Thib01

Hello,
maybe you should first find a tradesperson who:
The second point is essential if you want a proper result.
Without knowing the details, it seems to me that this is basically a very lightweight aerated concrete block? Handling it appears to be considerably more complex than EPS.

Has anyone calculated how much can be saved with this measure?
Poroton 36.5cm (14 inches) should not have poor thermal insulation, even back in '89.
In contrast, a material cost of 14,000€ ... you can heat for a long time with that. But you also picked some premium panels, listed at 33€/m² (3.07 $/ft²), EPS costs only a quarter of that. I understand not wanting EPS, but if the calculation no longer adds up at all, it doesn't make sense anymore.

Hello,
I would like to hand over everything to a single contractor, meaning both the installation and the materials. The problem is the price. I have two quotes for mineral wool insulation; the price per square meter is €149 for the first offer and €178 for the second. I should mention that the house will need a new high-quality plaster anyway, which is included in these prices. However, since Multipor panels are more expensive than mineral wool, the price per square meter will be even higher with this material! Totally uneconomical.
@Andreas
Unfortunately, I suspect you are right. If you want to use good (and clean) materials, it takes way too long to recoup the investment through the saved heating costs. I will probably only renew the high-quality plaster, which sadly means a bit more environmental impact. Still, if I find a company that would do the work at a fair price, everything is still open. That’s why I’m also asking whether this material is easy to work with.

Hello,
I insulated the exterior of my house with 160 mm Multipor, and used 50 mm Multipor interior insulation in my basement, and I am very satisfied!
The house has a noticeably healthier indoor climate from day one because the insulation material genuinely "breathes."
Multipor is made from calcium silicate and appealed to me because of its purely mineral properties.
As a comparison, my house was built in 1945 and constructed from 24 cm (9.5 inches) pumice stone blocks. In this case, it was easy to notice the improvement.
Multipor is quite crumbly but very easy to handle and work with. Since everything is bonded with lightweight mortar, all components must be secured with impact anchors and pre-plastered with Multipor lightweight mortar and mesh. After that, the desired plaster or decorative render can be applied.
I hope this is helpful.
Best regards,
Christoph

RegardsI’m not so sure about that. How much energy is required for the production, delivery, installation, and disposal of the insulation? And how much oil or gas could have been saved during the same period? I guess you’d need to write a doctoral thesis to determine that approximately. My gut feeling is that external insulation is almost always ecologically meaningless. Financially, it might sometimes make sense (especially in new construction).
