Well-insulated windows play a key role in ensuring thermal comfort in our homes. Therefore, the use of appropriate insulating materials around window openings becomes extremely important. One of the increasingly popular choices in this field is Purenit - a material with unique properties that offers a number of benefits. Below are some reasons why you should consider using Purenit under your windows:

1. Excellent thermal insulation: Purenit is characterized by high thermal insulation, which makes it an ideal material for use under windows. It allows you to make tight and warm connections between the window joinery and the installation opening. This is quite an important feature due to the possibility of reducing heat losses resulting from the presence of a linear thermal bridge in this place. 

2. High compressive strength: The compressive strength of Purenit is in the range of 5.5-7.5 MPa. The material achieves high hardness and stability thanks to its specific density of 550 kg/m3. A window base made of Purenit will easily transfer loads even from large window structures.

3. Moisture resistance: Purenit is a moisture-resistant material, which means that it does not swell even when immersed in water. Thanks to this, you can be sure of permanent insulation under the windows, even if there are problems with moisture in the environment.

4. Ease of installation and durability: Installing Purenit under windows is relatively simple and quick. Milling is selected individually for a given type of joinery profile. The foundation will therefore fit perfectly to the frame, which makes its installation much easier. Additionally, Purenit is characterized by high durability, which guarantees long-term insulation protection. Moreover, Purenit does not rot or decompose.

5. Resistance to construction chemicals: Purenit does not react with most construction chemicals. It is resistant to solvents, diluted alkalis and acids as well as mineral oils.

6. Eco-friendliness: Purenit is an environmentally friendly material, which is an additional advantage for those who care about ecology and sustainable development.

To sum up, using Purenit under windows is a decision that brings many benefits. Thanks to its excellent insulating properties, high compressive strength, resistance to moisture and construction chemicals, and ease of installation, Purenit is an irreplaceable material worth considering when installing window joinery.
