The NK GZ 18 is a durable swift nest box designed for facade installation. This single facade box provides space for one breeding pair and can be installed under gutters, roof edges or an overhang \u2013 the natural nesting location of the swift.<\/p>\n

The NK GZ 18 single swift facade nest box is particularly suitable for mitigation and compensation measures on facades and can be easily applied in new construction, renovation and existing buildings. The nest box creates additional breeding space and contributes to nature-inclusive building and the preservation of urban populations.<\/p>\n

This nest box is also regularly used by the house sparrow. This increases the likelihood that swifts will discover the box. When swifts wish to occupy the nesting site, they usually take over the box from the house sparrows.<\/p>\n


\nDurable and lightweight material<\/strong><\/h5>\n

The nest box is made from fiberstone, a plant-based fibre concrete. This material is highly durable and lighter than Woodstone\u00ae.<\/p>\n

Its low weight simplifies installation, especially when mounted at height. In addition, the material is fire-resistant, making it suitable for use on urban facades.<\/p>\n

The exterior is finished with a spray cork coating. This finish provides additional protection against weather conditions and gives the box a natural appearance. As a result, the nest box has a long service life.<\/p>\n


\nSpecifically designed for swifts<\/strong><\/h5>\n

Swifts naturally breed high up in buildings, under roof edges and overhangs. Modern construction methods often close off these nesting opportunities. The NK GZ 18 restores this essential nesting function within the facade.<\/p>\n

The internal nesting chamber includes a nesting barrier that prevents eggs from rolling away. This increases breeding success.<\/p>\n

The entrance opening is reinforced with an additional cast-concrete entrance stone. This makes damage or excavation by larger birds, such as ring-necked parakeets, more difficult.<\/p>\n

An opening is located at the rear for inspection and cleaning. This ensures that maintenance remains practical and extends the service life.<\/p>\n


\nApplication in projects<\/strong><\/h5>\n

The NK GZ 18 is suitable for small-scale applications. For optimal results, it is recommended to install several nest boxes together, both horizontally and vertically.<\/p>\n

For projects with multiple breeding spaces, the NK GZ 19 (double)<\/a> or NK GZ 20 (triple)<\/a> can also be selected.<\/p>\n
