Our brand new Rendered Build-In Swift Box is manufactured to UK Brick Size Specifications.
This nest box as the name suggests it suitable for the Swift. Swifts see our buildings as substitute “rockeries” where they would breed in a natural habitat.
The population of these birds has declined since the 1970s and all three species are now on the Amber List of Birds of Conservation Concern. Property maintenance and renovation often denies access to these birds, so providing a specially designed nest box is a practical way of helping the species and may be a condition of planning consent.
Cavity nesting birds are also known to use Swift boxes as nesting sites.
This nest box is made of the durable material WoodStone®, a mixture of wood fibre and concrete. The nest box is completely bricked in. At the front the nest box is finished with brick slips, all of them have to be created a 6 cm wide and 3 cm high entrance aperture.
The entrance hole is on the centre line and the two nest pans inside allow it to be fitted either way. This block is placed on the outside wall and will sit 50mm in the cavity leaving 50mm or more for insulation depending on your cavity size
This block can easily be fitted in walls against a warm space as it allows room for insulation and avoids thermal bridges The front of the box has 20mm protrusion so it easy to rendered around the entrance once in place. Preferably install in the gable end on the north or east side of the building 3 courses down from the top. It must be a minimum of 4m from the ground. Keep the flight path of the nesting box clear so do not allow trees or shrubs to grow in front of the wall.
Swifts likes to breed in colonies, it is therefore advisable to build in several boxes together. The distance between the boxes must then be at least 40 centimetres.
