Gierzwaluw renovation cabinet GZP4 – half recessed, half surface-mounted, wood-concrete | Unitura

The GZP4 is a permanent swift nest box for renovation projects, made entirely of wood concrete. The box protrudes from the facade and therefore only needs to go 10 cm into the wall, so you can easily replace it where existing nesting sites are lost.

• Made entirely of wood concrete: long lifespan and stable internal climate
• Only 100 mm installation depth, also suitable for facades from the 1950s and '60s with little cavity space
• Sloping entrance to prevent water ingress and a sloped roof to deter predators
• Drip design at the top and bottom: the facade remains clean
• Fire class A2

Tip: place the box at a height of at least 5 meters on a cold facade (north/east) or under an overhang.

Placement

Place swift nest boxes as high as possible, preferably at least 5 meters, with a completely clear flight path free of trees, eaves, or flagpoles. Preferably choose a cold facade (north/east) or the shade of a wide gutter or overhang. Because the box protrudes partly from the facade, a roof or overhang above it is recommended to prevent rainwater from accumulating on the top.
