protikrytí

Protikrytí is a Czech term that translates to "counter-covering" or "counter-sheathing" in English. It refers to a specific type of building construction, particularly prevalent in historical Czech architecture, where a secondary layer of material is applied over a primary structural element for various purposes. This secondary layer is not the main load-bearing structure but serves as a protective, insulating, or aesthetic addition.

Common applications of protikrytí can be found in roofing systems, where a layer of wooden planks or reeds might be placed over the main rafters or beams before the final roofing material, such as tiles or shingles, is applied. This intermediate layer provided an additional barrier against weather, improved insulation, and offered a more uniform surface for the final covering. In some cases, protikrytí was also used on walls, particularly in timber-framed buildings, where a plaster or wattle-and-daub layer might be applied over the timber structure to provide a smoother and more weather-resistant exterior surface.

The function of protikrytí varied depending on its material and placement. It could enhance thermal insulation, prevent wind and rain penetration, and contribute to the overall structural integrity by distributing loads or protecting the primary structure from decay. The specific materials and techniques used for protikrytí evolved over time and were influenced by local availability of resources and regional architectural traditions. Understanding protikrytí is important for historical building analysis and restoration efforts in the Czech Republic.
