Expansion profile made of plastic for underfloor heating /2m/ FBSOTHEFB5007600

Underfloor heating expansion profile – the key to a durable installation

This plastic expansion profile, 2000 mm long, is an essential element of every underfloor heating system. Its task is to properly divide the screed into heating zones, ensuring optimal performance and minimizing the risk of damage. It is also important to protect the pipes and the floor itself from cracking, which translates into the longevity of the entire installation.

This profile is particularly important in situations where the area of the screed exceeds 40 m², one of its edges is longer than 8 meters, the ratio of edge lengths exceeds 2:1, or the room has an irregular shape (e.g., L, T, C). It is also necessary in every doorway. Remember that omitting expansion joints in such cases can lead to serious problems with the floor structure.

Installation and application – for professionals and users

The expansion profile is glued to the rolljet, indicating the shapes of the heating zones, within which the coils should be laid. In places where the pipes intersect the expansion joint, protective tubes with a length of 40 cm must be used. Before pouring the screed, a polyethylene foam tape with a thickness of 8 mm is inserted into the profile – its height (100 mm) ensures visibility of the expansion joint for workers laying the finishing floors. The excess tape is cut off only after laying the finishing layer.

• Correct division: Ensures optimal heat distribution and underfloor heating efficiency.
• Pipe protection: Protects pipes from mechanical damage during screed pouring and operation.
• Crack prevention: Minimizes the risk of cracks in the floor caused by thermal stresses.
• Easy installation: Enables quick and precise execution of expansion joints during underfloor heating installation.
• Durability: Made of durable plastic, resistant to damage and external factors.

It is worth remembering the correct consumption of edge tape and the addition to the screed, to ensure optimal insulation and thermal conductivity of the heating screed. Choosing the right materials and following the installation rules is a guarantee of trouble-free operation of the underfloor heating system for many years.
