Introduction to Lepenka
Lepenka, often referred to as roofing felt, is an essential layer in roofing systems. It provides a water-resistant barrier beneath shingles or other roofing materials.
Historical Development
Initially, lepenka was made from natural fibers and bitumen. Over time, technological advancements have led to fiberglass-reinforced and synthetic underlayments with superior durability.
Installation Techniques
Proper lepenka installation involves rolling it out uniformly and nailing it down, ensuring an overlap between sheets to prevent leaks. Incorrect installation can compromise the roof's integrity.
Advantages of Lepenka
Besides water resistance, lepenka also offers protection during construction, acts as a secondary barrier for moisture, and improves the roof's fire rating.
Choosing the Right Lepenka
The choice of lepenka depends on climate, roof design, and local building codes. Options range from traditional asphalt-soaked felt to synthetic products with varying degrees of permeability and durability.
Unexpected Lepenka Uses
Surprisingly, lepenka has been used beyond roofing for creating temporary waterproofing on construction sites and as a base layer in some flooring applications.
Maintenance and Lifespan
While often overshadowed by top layer materials, lepenka requires inspection, especially after severe weather. Its lifespan typically aligns with the shingles it underlays, necessitating replacement every 15-30 years.
