Qualitative finishing works
Finishing of the window opening.
When the new the window is encased, it is necessary to carry out finishing works of the opening the window, normally plasterboard is used for such work, which is faster and visually appealing, but in this case, there are voids between the opening and plasterboard. Voids are also formed between the opening and the sill.
Voids in the building are not favorable for either man, or the building, but it’s a favorable environment for the development of all sorts of bacteria, if the condensation appears in voids, the loss of heat also increases due to the voids.
Therefore, all voids should be filled in, besides not with foam but with mineral wadding, and only after that covered with plasterboard. Wool fills the void well, eliminates the accumulation of condensation and performs insulation function. Perfect filling is impossible with foam, particularly under the sill, there is also the possibility to deform the sill, if too much foam is applied.
