Basement profile: purpose, characteristics, installation procedure step by step

The plinth profile is designed to provide support for thermal insulation and finishing materials, as well as to protect their lower ends. It is also necessary if the facade line is curved or has other flaws. In such conditions, when installing the basement profile, PVC expansion joints and connectors are used.

Types and characteristics of the basement profile

The basement profile is rarely used for self-decoration and insulation of houses. This is an unacceptable miscalculation that can provoke a lot of trouble during the operation of a building.

All technologies for the construction of modern facade systems provide for the installation of a basement profile. Therefore, it is unwise to ignore the recommendations of experts.

There are three types of these materials:

  • aluminum;
  • PVC;
  • two-part.

Base-base aluminum starting profile with 53 mm drip tip

Products of this type are made of anodized aluminum, which is maximally resistant to moisture.

As a result of the use of a special method of metal processing, a thin protective film is formed on its surface, which has a sufficiently high resistance to mechanical stress. But nevertheless, when installing an aluminum basement profile, one should strive to avoid the formation of scratches on the metal. Subsequently, corrosion may develop in these places.

Starting basement profile

The basement profile is a U-shaped bar, one shelf of which is lower than the other. The higher one has a perforation through which the aluminum strip is mounted to the wall of the building.

The second shelf also has holes and is equipped with a drip bend, which serves to drain moisture from the materials adjacent to the profile.

Aluminum basement profile is produced by both domestic and foreign enterprises. The most famous and popular brands are Rostec, Alta-Profil, Profil Systems, BauKom (Germany).

PVC profile

The shape of the strips of this type of profile is the same as that of aluminum. The only difference between these products is the material of manufacture. For the production of PVC profiles, high-strength plastic is used, which is not afraid of frost, moisture, or corrosion. It also successfully withstands temperature extremes.

PVC basement profile, fastening scheme

Another difference between PVC and aluminum profiles lies in the significantly lower price. This is one of the reasons why this type of support strips is predominantly used in private housing construction. When erecting industrial and civil construction projects, an aluminum profile is mounted.

PVC base / plinth profile composite

This type of profile has its own design features. It consists of two parts: back and front (end) strip.

The back is L-shaped. One shelf of the bar has holes for mounting fasteners.

The second shelf has a U-shape. The second part of the profile, the front, is inserted into this narrow groove. On its outer side there is a drainage outflow and a strong reinforcing fiberglass mesh.

Such a profile device allows you to adjust the distance between its first and second shelf. Fiberglass mesh is an additional supporting element and is necessary when plastering facades.

Accessories for the plinth profile

The accessories for the plinth profile can be used to create a perfectly straight facade line. Connectors are required to connect aluminum or PVC strips.

These products represent a solid plate with hollow U-shaped ends. Aluminum strips are inserted into these slots, which must be connected to each other.

Connector for base / plinth profiles

Using the connector

If the basement profile does not fit tightly to the wall, special products are installed between it and the bearing surface - expansion joints. They all have holes through which installation is carried out. The role of expansion joints lives up to their name.

The thickness of these components may vary. Choose the one that is required to cover the gap between the load-bearing wall and the aluminum strip.

Compensators

For mounting the basement profile, in addition to the accessories, you will need dowels or dowels-nails. If the walls of the facade are uneven and expansion joints are used, spacers of various diameters are used along with the fasteners.

Installation of the basement profile

When carrying out thermal insulation works more often all use an aluminum or PVC profile.

The width of the strips should correspond to the thickness of the insulation material. Installation technology is as follows.

Step 1. Perform horizontal marking of the lower boundary of the heat-insulating layer. In order to draw a straight line, use a level or bubble level.

If the length of the facade is significant, self-tapping screws are screwed in each of its corners and a strong thread is pulled between them. The profile can be set along it, or a line drawn by a marker.

Step 2. Work begins from the corner of the facade, therefore, the corner element is first made from the basement profile sheet. This is done as follows:

  • lay the profile on a flat surface so that its shelves are directed upwards;
  • stepping back from the edge of the profile 40-50 cm, on the lower shelf using a ruler and a simple pencil draw a line perpendicular to the side shelves;
  • align the angle of a metal construction square with this line;
  • draw lines in a square so that a right angle is obtained;
  • with scissors for metal or angle grinder with a disc for metal cut out the right angle obtained as a result of marking;

    Cutting the profile

  • bend the notched part of the profile and break off ( cut);
  • cut the connector so that its length corresponds to the length of the cut in the profile;
  • install the connector on one of the cuts;
  • bend the profile so that the cut lines through the connector fit snugly together.

Step 3. Attach the profile to the corner of the facade and mark the attachment points on the wall using a marker through the perforation in the high profile shelf. They should be at a distance of 30-50 cm from each other. The size of the step between the attachment points depends on the weight of the insulating material. If it is a lightweight foam sheet, you can increase the distance to 50 cm.

Step 4. Using a drill and a carbide-tipped drill bit, drill holes in the wall.

Step 6.

Through the perforation in the profile and the compensator, install a hollow into the hole in the wall rod (dowel).

Step 7. Use a hammer to hammer a nail into the dowel. The plinth profile is fastened along its entire length.

After the completion of the work, proceed to laying the insulation. Its lower ends must be installed in the recesses of the starting plinth profile. If the insulation is glued, glue must first be applied to it.

Upon completion of the thermal insulation work, the gap between the wall and the basement profile is filled with moisture-resistant and frost-resistant foam.
