Barrier papers made of kraft papers or liners, play a crucial role as windshields and barriers in half-timbered and similar constructions. These papers are used to prevent condensation and molding, ensuring the longevity and structural integrity of the building. However, it is important to understand the correct placement of these barrier papers to optimize their effectiveness.

In colder climates, where the risk of condensation is higher, it is recommended to use a polythene-coated kraft paper on the inner side of the wall. This dense barrier prevents moisture from penetrating into the structure, protecting it from potential damage. The inner side, being closer to the warmest surface, needs the highest level of protection to avoid condensation buildup.

On the other hand, the outer side of the wall must be permeable to allow any moisture that does penetrate the structure to escape. This can be achieved through the use of a porous or perforated barrier paper. It is essential to strike the right balance between preventing moisture ingress and allowing moisture egress to maintain a healthy and dry environment within the building.

The role of barrier papers goes beyond moisture control. They also act as wind shields, preventing gusts of wind from permeating through the walls. This helps maintain a comfortable indoor environment and can contribute to energy efficiency by reducing heat loss.

When selecting barrier papers, it is important to consider their quality and durability. High-density kraft papers or liners are recommended, as they provide better protection against moisture and wind. Additionally, the use of polythene coatings can enhance the barrier’s effectiveness, making it more resistant to moisture penetration.

Proper installation of barrier papers is crucial for their effectiveness. They should be carefully placed, ensuring complete coverage of the wall surface without any gaps or overlaps. Attention should also be given to the sealing of joints and edges to prevent any potential entry points for moisture or wind.

In conclusion, barrier papers made of kraft papers or liners, are essential components in half timbered and similar constructions. They serve as effective wind shields and moisture barriers, preventing condensation, molding, and potential damage to the structure. Proper placement and selection of barrier papers are vital to optimize their performance and ensure a dry and comfortable indoor environment. By employing these papers correctly, we can enhance the longevity and sustainability of our buildings.
