The device foam on the wall begins with the installation of the starting profile. Its width is equal to the thickness of the sheet foam. Sometimes for these purposes, the UW-50 or 100 profile is used. These are the most popular sheet sizes for insulation.

The start profile is mounted on the previously marked markup. Its use allows laying the first row of sheets absolutely smoothly. In addition, there is a popular belief that a metal starting profile will help protect the sheet from rodents.
To level the thermal expansion of the metal, between the adjacent profiles you need to leave a gap of about 5 mm. (more…)
