Presenningar

Presenningar are large sheets of waterproof fabric used as coverings to protect goods, equipment, buildings, or people from rain and weather. They are widely used in construction, agriculture, transport, and outdoor activities. In Swedish and Norwegian contexts, presenning is the term for tarpaulin or tarps.

Most modern presenningar are made from polyethylene (PE) or PVC plastics, often with UV stabilizers to resist sunlight. Historically, canvas or oiled textiles were common. Tarps typically feature reinforced edges with grommets (eyelets) at the corners and along sides for tying or anchoring, and they may be reinforced with additional fabric or webbing. The weight and thickness are described differently depending on the material, such as grams per square meter (gsm) for fabric-based tarps or mils for plastic ones. Some presenningar are waterproof throughout, while others may be water-resistant and designed to shed moisture.

Common properties include waterproofing, durability, and, in many cases, color-coded options. Blue is a familiar color in outdoor and construction settings, but tarps come in a range of colors and sizes to suit different tasks. Some presenningar are designed to be breathable to reduce condensation, but most primary uses emphasize water resistance and protection from the elements.

Typical uses include covering stock or scaffolding at construction sites, shielding crops or stored equipment in agriculture, serving as ground sheets or temporary roofs for camping and outdoor events, and providing emergency shelter in disaster or camping situations. Care and maintenance involve keeping them dry when stored, avoiding prolonged sun exposure to extend life, cleaning with mild soap, and repairing small tears with patches or suitable tape.
