Are you looking for a durable material that can handle moisture, heat and mechanical stress while maintaining its shape and functionality for a long time? One such material is purenit. In this article, we will take a detailed look at its properties, advantages and most common areas of use.

What is Purenit?

Purenit is a healthy product that, thanks to its unique properties, has found a firm place in the construction and industry. It is a light, rigid and extremely durable board made of hardened polyurethane foam with high functionality and variability of use. Its main advantage is dimensional stability, high resistance to moisture and excellent thermal insulation capabilities. Thanks to these properties, purenit is used in a wide range of construction and insulation solutions, where it replaces less suitable materials such as wood or metal.

Advantages of Purenit

High moisture resistance - Purenit does not absorb water, making it ideal for use in places where there is a risk of condensation or direct contact with moisture (for example, under-window sill boards or lining lining).

Dimensional stability and strength - Thanks to its solid structure, the material keeps its shape for a long time and does not deform even with temperature changes.

Excellent thermal insulation properties - Purenit helps reduce thermal bridges, thereby contributing to the energy efficiency of buildings.

Good workability - The material can be easily cut, milled, glued or drilled, which will significantly speed up assembly work and increase flexibility in the design of details.

Environmental and health safety - Purenit is recyclable and does not contain harmful substances, making it suitable for use in interiors and passive buildings.

Resistance to chemicals - The material is resistant to common construction chemicals, such as PUR foams, sealants or adhesives.

Where can you use Purenit?

Building opening fillings and window installation

One of the most common uses of purenit is in the installation of windows and doors. It is used as a base profile or as an insulating window frame. It is an element that compensates for building irregularities, interrupts the thermal bridge and at the same time ensures a solid anchorage. Unlike wood, purenit is not subject to rot, does not absorb water and does not change dimensions over time. Therefore, it is an ideal choice for insulated facades and for reconstructions, where the emphasis is on long-term stability and maintenance-free.

Insulation of lining and window sill parts

Thanks to its excellent workability and dimensional accuracy, purenit is widely used in the internal and external insulation of window and door linings. It significantly reduces heat loss in sensitive details of the connection of windows to the masonry. It is also used as a supporting base under external and internal window sills, especially in low-energy and passive houses. It contributes to the overall tightness of the building and prevents the formation of condensation and thermal bridges.

Underlay and spacer elements in construction

Purenit is also used as a base or spacer element where it is necessary to ensure strength, stability and at the same time prevent the spread of heat or cold. It is used under beams, thresholds, balconies, roof structures or load-bearing frames. Its compressive strength makes it a reliable material even for loaded details, without the risk of sagging or settling over time.

Industrial and technical applications

In addition to construction, purenit is also used in various industrial sectors. It is used, for example, in the production of special packaging systems, in the production of thermal bridges for technological equipment or as a filler for technical covers. Its insulating capabilities and resistance to chemicals make it a universal material where conventional building elements fail.

Purenit is an extremely versatile material that has its place in construction, technical and industrial solutions. If you are looking for a material that will withstand moisture, temperature fluctuations and time, purenit is a worthwhile choice.
