Material Guide: Woodcrete

Whether you have upcoming new developments or are looking to enhance existing construction projects with wildlife habitat, you may have come across the term ‘woodcrete’, ‘woodstone’, or a variation of the name. This hardy material is commonly used in bird and bat boxes and is often favoured for its longevity and cost-effectiveness. Here we take a closer look at woodcrete, its properties and manufacturing to help you make informed decisions when beginning new construction projects.

What is woodcrete?

Originally patented by Durisol and developed for the construction industry, woodcrete is a building material composed of cement, wood fibres and water. The material is referred to by a number of names, though they are almost identical in composition – woodstone is a trademark registered by Vivara Pro and woodconcrete is the term used by Schwegler, Faunus and Unitura, all suppliers of woodcrete bird and bat habitats.

Woodcrete Properties

A long-lasting, durable material, woodcrete can last for decades. It is weather resistant, does not support fungal growth and unlike wood products, does not rot. It does not leak, warp or crack, making it the ideal long-lasting, secure material for wildlife habitats.

The breathability of the material reduces the risk of issues with condensation, helping to maintain a healthy environment for roosting inhabitants.

It has good insulative properties and creates a stable environment inside the box to shelter inhabitants from extreme temperatures – especially important for maternity boxes where young are resting.

More lightweight than concrete, with great durability and strength, this material is suitable for both built-in and mounted nest boxes. The rough inner surfaces provide texture for bats to cling to, and create a safer, more natural environment for nesting animals. Built-in boxes can also be incorporated into brickwork and can be rendered over to blend into the structure whilst providing habitat benefits for local wildlife.

Woodcrete Applications

Woodcrete is used as a construction material, as well as a variety of building and garden products, including artificial habitat products to support wildlife. These can include bat boxes, bird boxes, insect hides, bee bricks and hedgehog domes. Most commonly, woodcrete bat and bird boxes are available in built-in forms that are installed directly into the walls during the construction of new developments. These boxes are designed to cater to species subjected to habitat loss resulting from the development project itself, or urbanisation in the general area.

Manufacturing process

The material is made by chipping specially graded recycled waste wood and mineralising the chips to neutralise sugars. The chip is mixed with cement and water to create the woodcrete mixture, before being poured into moulds like regular concrete. These moulds are cured at high temperatures to ensure strength and weather-resistance and can take a considerable amount of time for the full curing process to take place.

The manufacturing of woodcrete materials is a lengthy process which can cause a longer lead time for certain products. It is recommended to buy any product manufactured using woodcrete in advance to avoid delays or disappointment.

Integrated Bird Boxes for New Builds and Developments

Built-in bird boxes can be an excellent way to support diversity and incorporate additional habitat into new builds or redevelopments. Some boxes are specifically designed to cater to certain species, while others are more generalist and are suitable for multiple species. Generally, bird boxes consist of a large internal cavity and an access hole in various shapes or locations depending on the target species. They can be made from a variety of materials, however, woodcrete (or woodstone, woodconcrete) is generally preferred due to its robustness, longevity and advantageous thermal properties.

As low impact, wildlife-friendly construction gains momentum, more choice is added to the market each day, and the range is extensive. We stock the largest range of integrated bird boxes in the UK, so here we provide an overview of our bestselling built-in bird habitats, discussing the types of boxes available and their benefits.

Integrated Swift Boxes

Swift populations have declined over recent decades due to changes in roof design and the choice of materials used to construct our homes and public buildings. This species typically uses existing holes, cracks and crevices to build their nests, especially those in old buildings, so built-in swift boxes are recommended to provide areas for these birds to roost. These boxes provide large internal cavities within the brickwork that can be accessed by horizontally elongated, often downward facing entrance holes. As colony breeders, it is recommended to site multiple swift boxes together, situated with a clear flight path. The boxes should be installed at a minimum height of 5m on a non-south facing wall and should have no less than 40cm between entrance holes.

Integrated Sparrow Boxes

House Sparrow populations have undergone significant declines in previous decades and remain in a vulnerable state in the UK. As colony nesters, this species would benefit from boxes that are installed close together, or a larger, terraced box with multiple connected chambers. These built-in sparrow boxes consist of a durable woodcrete housing with a discrete entrance hole and a large cavity chamber (or alternatively multiple chambers) for nesting.

Integrated Bat Boxes for New Builds and Developments

The range of integrated or built-in habitats designed for bats can be overwhelming. For new developments, or renovation projects, you may be searching for bat boxes to incorporate additional habitat into your build, and support species while providing new infrastructure. With an upturn in low impact, wildlife friendly construction, integrated bat products are becoming increasingly relevant in the construction sector. Bat boxes are designed to provide an appropriately sized, predator-free space for bats to roost or hibernate. They are designed to be built-in to the building itself, whether this be roofing or brickwork and are unobtrusive, often hard to spot, and help to provide various species with a permanent roost.

There are 18 bat species in the UK, all of which use the same areas of buildings to roost in the absence of natural habitats – most commonly cellars, roofs and loose brickwork, among many more. In general, bat boxes should be placed between 3-6 metres high, in a sunny location with around 6-8 hours of direct sunlight. It is also best to avoid placing these in areas around artificial light. For built-in products, woodcrete (or woodstone, woodconcrete) is preferred due to its durability, longevity and good insulative properties.

Here we discuss integrated bat boxes, providing an overview of our selection of bat habitats and their benefits.

Types of Integrated Bat Boxes

Bat Tiles, Bricks and Panels

Tiles, bricks and panels provide bats with an access point to a suitable roosting space, whether this be within the roof, ridge tiles or a cavity area behind bricks and panels. They are designed to be incorporated into the build itself during construction or renovation and should be provided with suitable roosting cavities behind the access point, usually in the form of bat boxes or insulation-free cavity space.

Integrated Bat Boxes

Bat boxes are designed to cater for either crevice and cavity dwelling species through varying complexity or can occasionally be a hybrid design to encourage uptake from both groups. These self-contained roosts are unobtrusive and are typically installed flush to the wall or can be rendered over. Bat boxes can also be designed for hibernation and breeding, providing a well-insulated, larger space to accommodate breeding colonies and larger groups.

Bat Box Basics: A Guide

Whether you are planning a construction project, are in the middle of a new–build or are looking to update an existing structure, you may be exploring options for providing bat habitats. We have an extensive range of bat boxes available on our website, in a variety of formats and materials. Here we explore the different types, how they may be used and where they can be installed.

Bat Box Material Properties

Bat boxes are constructed with a variety of materials, each with differing properties.

Most commonly used for external boxes, wood is lightweight with good thermal properties for inhabitants. However, it does rot without treatment and therefore does not last as long as other materials.
Woodcrete (also named woodstone or woodconcrete) is a very durable material with exceptional thermal properties and is often the material of choice for built-in boxes. It can also be used externally and can last several decades once installed.
Eco-plastics are used to create lightweight boxes, typically designed for external use. They have good weather resistance and longevity, although less durability.
Concrete is exceptionally durable and is used for built-in boxes. It has good thermal properties but due to its weight, is unsuitable for external mounting.

Maternity Boxes

Typically larger in size with multiple internal chambers, maternity boxes are designed to support breeding colonies by providing a well-insulated roosting space for raising young.

These boxes are mostly made for external installation but are also available in a built-in format which is installed into the brickwork and can be rendered over.

Since these boxes are mostly available in an external form, they can be installed once construction has taken place. Built-in boxes should be fixed during the construction process and installed directly into the brickwork.

Example:

Improved Roost-Maternity Bat Box

#187787

An FSC certified crevice box, suitable for roosts or maternity groups.

Bat Tubes

Bat tubes are longer internal cavities with multiple sections or crevices. These are often made of woodcrete and are available in modular versions which can be connected in the facade allowing for side-by-side or a longer tower format.

These boxes come built-in and are incorporated into the building’s brickwork during exterior wall construction where they can be rendered over.

Example:

Unitura Modular Bat Tubes

#264632

A modular option available in multiple depths and styles for crevice and cavity species.

Bat Bricks

Constructed to industry standard size, bat bricks have a dome-shaped access hole to allow bats into a suitable cavity.

These products are designed to be incorporated into the brickwork of a building, whether this be a new build or an existing structure under renovation, and are available in standard colours enabling them to seamlessly blend into existing walls. When installing bat bricks, it is important to ensure that a chamber free from insulating material is available behind the access brick to allow bats to safely roost.

Example: 197697

Bat Access Brick

#197697

A standard-sized brick available in red, golden and brown colours.

Access Tiles and Panels

Similar to bat bricks, these tiles provide an access point to open roof space or the underfelt of the roof, allowing bats to nest in confined spaces beneath the tiles. They can be installed within the roof or ridge tiles during construction, or they may be used to replace tiles on existing structures, and are available in multiple colours to blend seamlessly into existing tiles.

Bat access panels are also available to provide bats access to a roosting site, and are particularly advantageous for renovation projects with existing roosting colonies. These panels can also be rendered over, and can be installed at any point during construction.

Access tiles and panels require an insulation-free cavity behind the product to provide nesting space.

Examples:

Bat Access Tile Set

#187127

This set includes three tiles available in five traditional roof tile colours.

1FE Schwegler Bat Access Panel

#180333

A woodconcrete access panel with an overall depth of just 8cm for easy integration.

Bat Box

These boxes are available as external or built-in designs and consist of a simple box with an entrance hole and varying interiors. Bat boxes can come in a range of forms, and can have one large, single cavity or a multi-chamber interior and can cater to both crevice and cavity-dwelling bats. There are also hybrid options, where a box is designed with cavities for multiple species, for example a box may cater to bats and Swifts.

Built-in boxes are designed to be installed among the brickwork and can be rendered over. External boxes can be mounted to trees, fences and buildings with the appropriate fixings. It is important to consider the weight of an external box before mounting, more lightweight boxes (made from wood or plastic for example) can be fixed to trees, but heavier woodcrete boxes should be fixed to a solid structure.

Examples:

Large Multi Chamber Woodstone Bat Box

#246918

A large multi-chamber box that is also suitable as a hibernation, maternity or summer roosting space

Kiki Bat and Swift Hybrid Box

#261420

A hybrid box designed to support multiple species, including cavity and crevice dwelling species.

PRO UK Build-in WoodStone Bat Box

#256321

A maintenance-free woodstone box designed to work with UK brick dimensions.

Elisa Bat Box

#259840

Features a single internal cavity that is suitable as a summer roost.

Rocket box

Rocket boxes are large, pole-mounted habitats that provide a large roosting area over multiple chambers. Typically made with a plastic shell, these boxes allow for 360 movement and are available with both crevice and cavity designs.

Rocket boxes are external and do not attach to any part of the building. They are particularly useful when there are no suitable trees for external boxes, and a wall mounted box is undesirable. They have also been used to provide an alternative roosting site near building works.

Example:

Eco Rocket Bat Box

#242611

A pole-mounted bat box available in a cavity or crevice design.

Top 10 Bat Boxes for New Builds and Developments

Looking for a bat box but don’t know which one to buy? This article is the third in a three part series designed to help you to make the right choice. Here you will find our top 10 boxes for incorporating into the masonry of a new build or development. The previous two posts feature the best boxes for trees and woodland and for walls and fences.

For each box listed you will also find helpful information such as its dimensions and weight and the box type (e.g. whether it is for summer use, for hibernation or for access into an existing roost space).

The Glossary below provides a guide to the key terms used in the descriptions.

• Woodcrete/WoodStone: A blend of wood, concrete and clay which is very durable. It is also breathable and helps to maintain a stable temperature inside the box.
• Summer: Summer boxes are suitable for the warmer months but are less likely to be used over the winter.
• Hibernation: Designed to be larger and better insulated, hibernation boxes will provide a safe and warm space for bats over the winter.
• Maternity: Suitable for the formation of colonies and raising of young.
• Access: Provides an entrance to an existing roof space such as a wall cavity or loft.
• Crevice: Provides one or more narrow roost spaces. Species which prefer this type of box include common, soprano and Nathusius pipistrelle, Brandt’s and whiskered bats.
• Cavity: Provides a more spacious roost space. Bats such as brown long-eared, Daubenton’s and Natterer’s bats prefer cavity boxes.
• Large cavity: These boxes allow space for flight within the roost which is preferred by brown long-eared bats in particular.
