Application ThermaRod

ThermaRod is 100% recyclable PE foam insulation. The product has a circular cross section and its flexibility makes it very easy to use. ThermaRod is primarily used in the construction industry. It is very suitable for filling, sealing and insulating construction gaps and expansion joints created during work on foundations, floors, walls and roofs and when installing panels, windows, doors and building systems.

Due to its closed cell structure, the product is virtually impermeable to water. This makes ThermaRod very suitable for use in window profiles or on balconies etc. The material is strong and resistant to contact with rough surfaces and building materials such as cement, plaster, adhesive and concrete.
