PSUL for windows is a pre-compressed sealing tape. It is usually used when installing plastic and wooden windows for hydro and thermal insulation. PSUL tape can be of different lengths, thicknesses, and have different degrees of expansion. It all depends on the actual dimensions of the structure to be installed.
Description
PSUL is a self-expanding tape made of polyurethane elastic foam impregnated with a mixture of modified acrylic. It significantly improves the properties of polyurethane seals, increasing their resistance to aging. The tape enters the market in a compressed state, twisted into rollers. The sizes of the sealant are different, so it can be matched to any seam. Tape PSUL for windows has a layer of glue on the surface, which simplifies its use. Plus, it doesn't let her move. A highly compressed film expands only after the packaging is removed. Thickness up to five times possible.
PSUL for windows has many positive qualities - it is very elastic, able to take almost any shape, resistant to ultraviolet rays and heavy rains, perfectly ensures the release of water condensate from the product into the atmosphere. Thanks toits plasticity can fill any cracks. PSUL tape can be used with almost any building material: concrete, brick, steel, wood, plastic and other materials.
Where PSUL is used
Scope of self-expanding tapes are:
- sealing gaps in prefabricated structures, seams of ventilation ducts, drains, tile junctions, sewers;
- sealing joints, blocks, movable fixed joints.
Also PSUL for windows is used to seal the gaps between the opening and the door frame.
Foamed polyurethane tape impregnated with a special acrylic adhesive, suitable for both outdoor and indoor use. It is recommended to use tape sealant in residential and industrial buildings.
Material properties
Excellent material - PSUL for windows. The technical characteristics of the tape allow long-term operation of the products on which it is used. Here are the properties it is valued for:
- based on polyurethane foam impregnated with acrylic adhesive;
- thickness of the tape in a compressed state - from 2 mm, in an expanded state - up to 80 mm;
- resistance to deformation - not less than 14%;
- temperature resistance - up to +1000 degrees;
- fire resistance class - flame retardant;
- operation at temperatures from -50 C to +90 C;
- does not allow wind and moisture to enter the seam;
- PSUL tape for windows is not destroyed by variousweather precipitation;
- sun UV resistant;
- ventilates the seam, filters the resulting steam;
- tape sealant is chemically neutral;
- allows you to seal joints with uneven surfaces, such as a brick wall;
- makes it possible to carry out work at absolutely any air temperature;
- does not crack over time, while maintaining elasticity;
- withstands (up to three hours) a pressure of 600 kPa.
Installation of windows using PSUL
Installation is usually called the installation of a frame without sashes and double-glazed windows on support pads. The window must be oriented absolutely perfectly in accordance with the readings of the measuring instruments. What is PSUL for windows and what is it for?
Vapor-permeable hermetic tape is used during installation and serves as an excellent protection of the foam from the side of the street from exposure to ultraviolet radiation and moisture, prevents the growth of mold and mildew, and removes excess moisture from the installation seam. PSUL should be installed without fail (according to GOST). Such a sealant tape is placed on the frame around the entire perimeter immediately before installation - in a joint or in a seam, in order to increase the service life and avoid freezing or leakage. The protection of the mounting joint from the outside must be vapor-permeable, that is, all moisture condensate that forms in the pores of the foam during temperature changes must be removed to the outside.
To solve allthese tasks and use PSUL - a gray or black porous strip of elastic material (reminiscent of foam rubber) with special acrylic impregnations. Installation is carried out directly from the coil (roll). For the first time this technology was used by the German corporation Illbrook. Now in our country, the use of PSUL is no longer a rarity.
