Modern methods of sealing inter-panel joints

Современные методы герметизации межпанельных швов

In panel houses, panel joints are vulnerable places through which moisture, cold air and even dust can penetrate. Sealing of such joints is not only a mandatory stage of building maintenance, but also an important factor affecting its energy efficiency and durability. Let’s consider modern methods and materials for sealing inter-panel joints.

Problems of old joints

Old sealants lose elasticity over time, cracking and deteriorating when exposed to temperature changes and moisture. This leads to:

  • Drafts.
  • Accumulation of condensation inside the structure.
  • Development of mold and fungus.
  • Deterioration of thermal insulation.

Modern sealing methods

  1. Initial sealing: This is carried out during the construction phase of the house. Modern materials such as polyurethane and acrylic sealants are used.
  2. Secondary sealing: This is used to repair and replace old joints. Remains of the old sealant are removed, the joint is cleaned and filled with new material.
  3. Use of thermoprofiles: These are special tapes that are installed in inter-panel joints for additional protection against moisture and cold.

Sealing materials

  • Polyurethane sealants: Provide high elasticity and resistance to temperature fluctuations.
  • Siloxane formulations: Have excellent water repellency and durability.
  • Insulation cords: Used to fill deep seams before applying sealant.

Advantages of modern materials

  • Durability: the service life of modern sealants is 10-15 years.
  • Resistance to external influences: materials retain their properties even in severe frosts and heat.
  • Aesthetics: sealants can be matched to the color of the facade.

Sealing stages

  1. Cleaning the joint from old sealant and contaminants.
  2. Installation of insulation cord (if necessary).
  3. Apply new sealant using a syringe or gun.
  4. Smoothing the sealant layer for even distribution.

Modern methods of sealing panel joints can significantly improve the energy efficiency of buildings, prevent mold and increase the service life of the facade.
