Hi everyone,
A wood-burning stove is also planned for our house. It will probably be a Skantherm Elements or Emotion M. They have a base footprint of roughly 60 x 60 cm (24 x 24 inches) and weigh between 150 and 250 kg (330 and 550 lbs) – 150 kg (330 lbs) without heat storage bricks, up to 250 kg (550 lbs) with them.
Now, in the documents for the construction meeting, our general contractor states that the screed can only be loaded with 150 kg/m² (31 lbs/sq ft). That seems very low to me, because that would mean that even two 80 kg (176 lbs) people standing 50 cm (20 inches) apart somewhere would not be allowed. Or more extreme: if 15 people watch the football World Cup final at my place, they shouldn’t all gather in front of the TV at once…
At least I wouldn’t be able to complain if the screed cracks.
It seems a bit absurd! From my professional experience in steel construction, loads below 300 kg/m² (62 lbs/sq ft) are basically unknown, and for industrial floors/screed it is never below 1000 kg/m² (205 lbs/sq ft).
The general contractor probably wants to be on the very safe side to always have an excuse ready later if any cracks appear.
The floor structure is as follows:
60 mm (2.4 inches) insulation
30 mm (1.2 inches) fixing panel (hook-and-loop system)
70 mm (2.8 inches) screed
15 mm (0.6 inches) parquet flooring
------
Total 175 mm (6.9 inches)
The general contractor now offers to install the screed in the stove area as a floating screed without thermal and impact sound insulation. He wants 145 € for that.
On the one hand, the 145 € seems steep (even though that wouldn’t make much of a difference overall), but above all I don’t want to create sound bridges under the stove.
And now the questions:
Thanks and best regards,
Andreas

And now the questions:
- Is such a low load capacity for screed normal?
- Is your stove placed on regular screed, or do you have reinforced screed under it? It’s clear that the underfloor heating is left out in that area.
- Can I place a stove on floating parquet? Ideally, I would like to have the parquet run continuously, then put a glass plate as a spark guard on top, and place the stove on that.
Thanks and best regards,
Andreas

AndreasIt’s exactly the same for me. I don’t see any reason why that shouldn’t be possible.

Sebastian7923 Feb 2016 14:29I wouldn’t recommend that due to edge loading. Our fireplace manufacturer specifically recommended a bonded screed, which we have installed – however, our fireplace weighs about 650 kg (1,433 lbs).
Heating pipes, water pipes, and electrical conduits definitely shouldn’t be placed there.
We’re also considering whether to extend the hardwood flooring through or to install tiles or similar around and underneath the fireplace. But with our three-sided fireplace, it probably looks very bad if there is hardwood all around but tiles within 50 cm (20 inches) of the fireplace. We have an expansion joint there anyway, but it is positioned just below the fireplace, so it’s not visible. This also solves the sound insulation issue.
