  • Installation of log house windows with self-expanding tape

    Years ago, foam replaced hard material that was used for the installation of windows as a protection from wind and cold. Today, a new comfortable and efficient product has been introduced – self-expanding sealing tape.

    It is a special elastic polyurethane sealant with open pores, impregnated with a sealing solution. Thanks to its density and elasticity, it protects windows from wind, rain and external air movements. The sealing tape is also fireproof. Areas of application In addition to the installation of windows and sealing of log houses, the sealing tape is also suitable for:

    • sealing the panel joints and ventilation systems of big residential houses made from precast concrete slabs,
    • noise and vibration insulation around ventilation and air exchange devices and in the automotive industry;
    • between roof elements and for other sealing works.
  • Vapour and wind barrier tape installation system

    In order to improve energy efficiency, we suggest using vapour and wind barrier tapes when sealing the joints to improve thermal conductivity and air density.The system consists of Penosil Premium Sealing Tape Internal (vapour barrier) and External (wind barrier), one of the high quality Penosil PU foams and adhesive Penosil Nail & Fix Universal.
  • How to use PU foam to seal exterior doors during their installation

    In this video, we use fire-resistant PU foam Penosil Premium FireRated Gunfoam B1 to install the exterior door.Always install the door according to the construction design, relevant requirements and producer’s instructions. Installation methods may vary, depending on the specific door design. Exterior doors are exposed to weather conditions and proper installation ensures their long-term functionality.
  • Differences between straw and gun foam

    In this video, we demonstrate the use of two PU foams, each with a different dispensing method, in the installation of interior doorjambs. For one doorjamb, we use a straw applicator and for the other one, a foam gun. As we see, using straw foam is rather uneconomic in this type of joints. In comparison with gun foam, a considerably larger amount of straw foam had to be used.
