Time required for screed insulation

Hello,

does anyone have experience with how long it roughly takes to install [Estrichdämmung] yourself? It will probably go very quickly on the area, but what about when ventilation ducts have to be included?
The background of my question is that we will soon receive an offer for a bonded filling throughout the whole house, and I would like to estimate how much time could be saved with it.

Our house will have ventilation ducts under the screed in the ground floor and upper floor and a total area of about 240m² across all three floors. I would be happy if someone could share experience on this topic.

Best regards
Holger

Hi elVincent,

we installed the screed insulation throughout the entire house and basement (approx. 230 sqm) completely by ourselves. However, we didn’t have ventilation ducts on the floor but "only" electrical conduits and water pipes. And we used Styrofoam, only covering the pipes with a filling.

It was quite a bit of work because cutting out the pipes took a lot of time and tinkering. I think we took about 3 weeks in total. After work and on Saturdays. (But not every evening, because at that time we also had other things to do)

We needed almost 9 full days for insulation over nearly 250 sqm on three levels. Very little loose-fill insulation was used, but a lot of carving, and a foil was laid out fully in the basement.

One insulation layer in the basement, two insulation layers in the other two floors.

An insane job that I never want to do again... but no screed layer will do it more carefully 100%.

We needed about 150 hours. 175 sqm living space, 2 levels, 4 layers of insulation Electric, ventilation pipes + water pipes. Today it would probably take less than 120 hours...

These are already very helpful answers. The processing of the bound filling that is offered to us probably goes relatively quickly, so I hope that the proportion of labor costs will not be too high.

Hello "elVincent". I just hope you are not confusing something there. Insulation layers - as their name suggests - have insulating properties, but they are also often used as (more expensive) height compensation when the local situation requires it. In the case of bound fill layers, their primary task is to create a uniform surface, that is to level areas that cannot easily be handled with insulation layers. Several products are available on the market that present themselves as combination products of height compensation as well as thermal and impact sound insulation. However, practice shows; this only works to a limited extent! If installations lie criss-cross on the raw ceiling (they must be fastened however!), it is not possible to do without height compensation like a bound fill layer. Unfortunately, this construction layer brings along the unwanted free water again (the layer must dry if no dry compensation was used), which in many cases has led to damage to the upper floor covering after months. By the way, a dry fill layer that interlocks due to its shape is also considered a "bound fill layer". -------------- You now have to decide which way is more sensible for your home. Dry fill layers must be leveled over screeds and should be compacted at a thickness of about 6cm. Whether you actually save labor time compared to laying an insulation layer is really the question. As far as cables or ventilation shafts have been properly installed on the raw ceiling, then the solution with insulation layers is probably the most sensible and also the most economical. ----------------------- Best regards: KlaRa
