Under Screed Thermal Insolation Solutions
You want to use such a product in your construction so that it provides both sound and heat insulation, does not collapse and is long-lasting. Here, we have collected the features you should look for about the product you will ask from the companies for this.
Advantages of Screed Underlayment
-The slurry of the alum does not enter its structure. Therefore, nylon etc. products are not used.
-Provides high heat insulation.
-It prevents impact-induced sounds from going to the lower floor.
-Breathes. It does not cause moisture, dampness and mold on the lower floor ceiling.
-Does not give waste.
-Easy to apply.
-It can be worked on comfortably. Does not break and deform.
-It is healthy.
-Additional wall tape is not used for floating flooring.

The surface is cleaned first.
Surface defects do not prevent the laying of izoBOZZ FeltBi felt.
IzoBOZZ FeltBi felt is laid side by side so that there is no gap on the floor.
There is no need to tape the joints.
Impact sounds travel to the lower floors both directly and through the side walls. For this reason, isoBOZZ FeltBi felts are turned to the wall as much as the thickness of the screed to be laid to cut the wall sound connection.
No additional tape is required.
The screed is poured so that it does not exceed the felt level.
When pouring the screed, since the grout of the screed does not penetrate into the structure of isoBOZZ FeltBi (see TSE Impact test), there is no need to lay nylon etc. on it.
Excess felts remaining above the screed level are cleaned by cutting with the help of a cutter after the parquet is laid.
