One of the most common mistakes in building construction is focusing solely on thermal insulation (rock wool, glass wool, etc.) while failing to give due importance to the membrane layer that protects it. However, insulation material loses its functionality when it becomes wet or is "blown out" by the wind. Izospan AF+ is a high-quality, reinforced diffusion membrane specifically designed to fill this gap.
In this article, we will take a detailed look at why this unique material, offered on Tvim.az, is essential for every modern construction project.

What is Izospan AF+ and How Does It Work?
Izospan AF+ is a protective layer with high vapor permeability. Its core operating principle is similar to a "one-way valve":
From inside to outside: It allows water vapor generated
inside the building (human breath, cooking steam, etc.) to exit through the
insulation layer without obstruction.
From outside to inside: It decisively prevents rain, snow,
and wind from the outside from penetrating the insulation layer.
Product Advantages: Why the "AF+" Model?
1. Maximum Vapor Permeability (Diffusion)
If vapor remains trapped within the structure, it leads to
moisture buildup and, consequently, mold, fungus, and decay. Izospan AF+
exhausts this vapor within seconds, ensuring that the walls and roof
"breathe."
2. Excellent Wind Protection
Wind causes a building to cool down by removing the warm air
from between the fibers of the insulation material (a phenomenon known as
"wind wash"). Izospan AF+ prevents this airflow, minimizing heat loss
and saving on energy costs.
3. Reinforced Structure (Strength)
The "AF+" series stands out for its exceptional
durability. This eliminates the risk of tearing during installation (for
instance, when workers step on it or when the material is stretched). The
material retains its shape and properties for many years.
4. Waterproofing Capability
Water droplets leaking through roof coverings or facade panels fall directly onto the Izospan AF+ and drain away without damaging the structure.

Where is it Used?
Izospan AF+ has a wide range of applications:
Ventilated facades: Essential for the exterior walls of
modern high-rise buildings and office centers.
Pitched roofs: To protect the insulation layer under metal
tiles, slate, or other roofing materials.
Frame houses: The best choice for moisture management in the
walls of timber or metal frame buildings.
Attic floors: To maintain a comfortable temperature in
residential attic spaces.
Conclusion: A Long-term Investment
Using a low-quality membrane in construction can lead to
expensive repair work in the future. Izospan AF+ is the optimal choice for
modern insulation systems due to both its easy installation and effective
protection properties. It increases the overall durability of the building,
creating a comfortable and healthy living environment.
If you want to ensure the health and longevity of your home
or project, you can obtain the Izospan AF+ membrane from Tvim.az under
favorable terms.
