PSUL for windows is a pre-compressed sealing tape. It is usually used in the installation of plastic and wooden windows for hydro and thermal insulation. The PSUL tape can be of different lengths, thicknesses, and have a different degree of expansion. It all depends on the actual size of the installed structure.
Description
PSUL is a self-expanding tape made of elastic polyurethane foam, which is impregnated with a mixture of modified acrylic. It significantly improves the properties of polyurethane sealants, increasing their resistance to aging. The tape enters the market in a compressed state, twisted into rollers. Sealant sizes vary, so it can be matched to any seam. The PSUL tape for windows has a layer of glue on the surface, which simplifies its use. Moreover, this does not allow her to shift. A highly compressed film expands only after the packaging has been removed. A fivefold increase in thickness is possible.
PSUL for windows has many positive qualities - it is very flexible, able to take almost any shape, resistant to ultraviolet rays and heavy rains, perfectly provides the exit of water condensate from the product into the atmosphere. Due to its ductility, it can fill any gaps. PSUL tape is allowed to be used with almost any building materials: concrete, brick, steel, wood, plastic and other materials.
Where do you use PSUL
The scope of self-expanding tapes are:
- sealing gaps in prefabricated buildings, seams of ventilation ducts, gutters, tile joints, 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 is suitable for both external and internal use. It is recommended to use tape sealant in residential and industrial buildings.
Material properties
Excellent material - PSUL for windows. Technical characteristics of the tape allow for a long time to operate the products on which it is used. Here are the properties that value her:
- based on polyurethane foamed with impregnation based on acrylic adhesive;
- the thickness of the tape in a compressed state - from 2 mm, in the expanded - up to 80 mm;
- resistance to deformation - not less than 14%;
- temperature resistance - up to +1000 degrees;
- fire resistance class - hardly flammable;
- 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 various weather conditions;
- resistant to solar ultraviolet;
- provides ventilation of a seam, filters the formed steam;
- tape sealant is chemically neutral;
- allows you to seal joints with uneven surfaces, for example with a brick wall;
- makes it possible to carry out work at absolutely any air temperature;
- does not crack with time, maintaining elasticity;
- withstands (up to three hours) a pressure of 600 kPa.
Installation of windows using PSUL
Installation is called the installation of the frame without sashes and double-glazed windows on the support gaskets. The window should be oriented absolutely perfectly in accordance with the readings of the measuring instruments. What is PSUL for windows and what is it for?
The vapor-permeable hermetic tape is used during installation and serves as an excellent protection of the foam from the street from UV and moisture, prevents the growth of mold and fungus, removes excess moisture from the installation joint. Install PSUL should be mandatory (according to GOST). Such a sealant tape is placed on the frame around the entire perimeter immediately before installation - in the joint or in the seam, in order to increase the service life and to avoid freezing or leakage. The protection of the installation joint from the outside must be vapor permeable, that is, all moisture condensate that forms in the pores of the foam during a temperature difference must be led out.
To solve all these problems, they use PSUL - a gray or black porous strip of elastic material (resembles foam rubber) with special acrylic impregnations. Installation is carried out directly from the coil (roll). For the first time, this technology was introduced by the German corporation Illbrook. Now in our country the use of PSUL is no longer a rarity.
