The adjoining window profile with a reinforcing mesh

The weak point of the window slope is the line of adjacency of the frame to the wall. Cracks often form on the seam, with insufficient sealing it is blown by the wind. Many problems arise in the process of plastering: you need to carefully bring out the even slope plane and at the same time make sure that the solution does not stain the frame and the glass packet. A special window adjacent profile with a reinforcing mesh will facilitate the work of the master. Let's find out why this element is needed, how to choose and use it correctly.

Assignment of an adjacent profile

This product is a universal bar that performs several functions at once:

• Plastering: a durable fiberglass mesh reliably holds the grout and reinforces it, prevents the appearance of cracks after drying. In addition, the profile itself acts as a beacon. A spatula or rule is supported on it and a neat and even slope is brought out.
• Sealing: the element ensures tightness of the seam at the junction of the slope with the window frame.
• Protective: not only prevents window contamination during plastering, but also resists atmospheric influences during further operation.

Profile device

This element is made of polyvinyl chloride in accordance with GOST 19111-2001. The material of the profile is resistant to shocks and temperature influences, it is not afraid of ultraviolet rays, it is easy to install, and it does not pass steam and water.

Structurally, the profile consists of the following elements:

• Basics from unplasticized (hard) PVC, on the back of which is a self-adhesive sealing lamella made of foamed polyurethane. It is with this part that the profile is glued to the frame. It allows the element to fit snugly against the window frame, and also plays the role of a kind of damper pad, compensating for the thermal expansion of materials and wind load. Quenching these vibrations, the lamella contributes to the preservation of the inelastic layer of the stucco plaster.

• Protective cuff - inserts made of soft plasticized PVC. After finishing work, this part of the product remains in sight. It forms a neat and aesthetic junction of the slope and the window unit and hides cracks that may appear on the corner seam over time.
• Tear bar with glue strip. By removing the protective film, it is easy to attach polyethylene or a membrane to it, protecting the window from contamination with plaster mortar. After completion of work, this bar is easily separated from the box.
• Reinforcing mesh made of alkali-resistant fiberglass attached to an additional shelf.

Self-adhesive plastic profiles with reinforcing mesh are used when forming slopes on the outside of the building and indoors.

How to choose

Some tips for choosing a profile:

1. The element must have a protective cuff insert that covers the junction of the slope and the frame in the absence of the perimeter of this joint will be visible to the end face of the sealing lamella made of foamed polyurethane which easily absorbs moisture and mud. It will get dirty more and more every window wash, and it will look completely ugly.
2. It is recommended to pay attention to the color of the product. It is desirable that it be made of primary PVC, which has a pure white shade. At the end of the work, the grayish PVC insert will stand out against the white frame and will not look very aesthetically pleasing. In addition, the dirty gray profile made of recycled PVC is worse in quality and breaks more easily.
3. It is important to choose the right adjacent profile in height. On sale there are models with a height of 6, 8, 9 mm or more. For standard plaster and putty finishes, an element with a minimum height should be selected. If the slopes will be insulated with foam, this value should be greater.

The marking of the models is as follows: 6 × 2400, where the first digit indicates the height of the profile, and the second - its length. For example, the profile is 9 × 2400: the height of the profile is 9 mm, the length is 2.4 m.

Installation

Mounting Technology:

• A line is marked along which the profile will abut the frame. It is most convenient to use the laser level, but in its absence, the bubble level is also suitable.
• The desired section of the product is measured and cut. To do this, use metal scissors.
• For good adhesion, the frame is pre-cleaned from dust and other contaminants. Only under such conditions does the manufacturer guarantee the reliability of the resulting compound.
• A protective film is removed from the damper lamella and the profile is glued to the frame along the marked strip. This is done as follows: having disconnected a little film, the strip is exposed in a line and pressed to the box, after which the remaining protective layer at an acute angle is removed completely.

• Having removed the protection, stick the material that covers the window from dust and dirt - a plastic film or a special membrane.
• Spreading the reinforcing mesh, spend the plastering of the slope.
• After the plaster dries, the tear-off strip is removed along with the film covering the window.

The installation of the profile is carried out at a temperature not lower than +5 ˚C.
