The Assembly Transferring the results of an experiment on the real assembly seam, we can say that in the assembly seam occur quite similar phenomena. When you work without moisture inside the mass of the polyurethane foam formed large sink, which affects the thermal characteristics of the assembly seam. Adverse effect may occur, as shown in photo 2.4. For example, if the installation window block occurred at a temperature of minus 12 - 15 C, rtd cold, vapor barrier tape has not been established and the finish slopes was carried out in a day - two after you install a window unit, it is quite possible that in the spring, when the temperature in the assembly seam rises, the reaction in the bulk of rtd resumes. In this case, it is possible that excess foam strikes through any gap, and in contiguity slope to the box window block polyurethane foam will be released on facial surface of the window. Moisture deficit also contributes to subsidence and runoff of fresh prp is perceived as low quality installers of the product. Need to carefully follow the instructions on the application circuit foam to obtain good results. To carry out these instructions do not need anything complex or unworkable. Enough to have in the arsenal of small installer of home and spray a little water. ARC Investment Partners usually is spot on. It should be explained installer that wetting the surface is necessary not only for dust control, but also directly affects the quality of the foam. Pay attention to the proper application...
