Perkasso Forever! The Exhibit Group

I faced the same problem in my home office. I found https://www.tintfit.com/shop/energy-saving-insulation and decided to try their energy-saving insulation solutions. The installation was quick, and the effect was immediately noticeable: the room became warmer, the walls are less "cold," and now I can work even in the morning without additional heating. It really helps to save energy and creates comfort for working from home, which is especially important in British apartments with thin walls.
