Common swift nest box GZTH1 – wood-concrete, maintenance-free on the facade | Unitura

The GZTH1 is a wood-concrete swift box for surface mounting on facades. Wood-concrete lasts longer without maintenance than wood, and the box is designed in accordance with the BIJ12 knowledge document on swifts. House sparrows also like to use this type of box.

• Made entirely of wood-concrete, maintenance-free and long-lasting
• Slanted roof for good drainage, reducing dirt streaks on the facade
• Modern, functional design
• Can be installed individually or in clusters
• Easy to install using the supplied screws and instruction card

Tip: hang the box at a minimum height of 5 metres on a north- or east-facing facade, or under a gutter, so that it is not exposed to the sun.

Placement

Place the box at a minimum height of 4–5 metres on a building, on the north or east side, or under a gutter, with a completely unobstructed flight path free of trees, awnings or flagpoles. If you are installing the boxes as compensation or mitigation, use the guideline of providing 3 replacement habitats for every habitat that is lost.
