Description
NK GZ 16 Swift Facade Nest Box Double
The NK GZ 16 is a durable swift nest box for facade installation. This version provides space for two breeding pairs and can be installed under gutters, roof edges or an overhang – the natural nesting location of the swift.
The NK GZ 16 double 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.
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.
Durable and lightweight material
The nest box is made from fiberstone, a plant-based fibre concrete. This material is highly durable and lighter than Woodstone®.
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.
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.
Optimal breeding conditions for swifts
Swifts naturally breed in colonies, where several nesting sites close together significantly increase the chances of colonisation. The NK GZ 16 is perfectly designed for this. The box consists of two separate units, each with its own fully separated nesting chamber for one breeding pair.
Each internal nesting chamber is equipped with a nesting barrier that prevents eggs from rolling away. This increases breeding success.
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.
Cleaning can be carried out by removing the cast-concrete entrance stone. This keeps maintenance practical and extends the lifespan of the nest box.
Scaling within the same system
The NK GZ 16 double swift facade nest box is ideal for medium-sized projects. For projects with fewer breeding spaces, the NK GZ 15 (single) can be chosen. For larger colonies, the NK GZ 17 (triple) is also available.
