millimetre precision of laying slabs onto pedestals

The new ASP EXTRA range.

ASP EXTRA 85-135mm

Soon installers will be able to pave a height range from 85mm right up to 380mm using only three different sized units. These pedestals have the added advantage of containing height markers each 10mm along the side of the stem, so installers can see at a glance how high the slab is lifted without having to constantly re-measure.

Sustainable Materials

Wallbarn also supplies a sustainable material in the form of recycled polyester material. These fabrics are available in a variety of densities and come either as a white material or a multicoloured fabric.

They represent significant cost savings and as they are recycled materials they help with sustainability criteria including BREEAM ratings, for example.Sustainable Materials

Both fabrics have a lower tensile strength than virgin materials, but this reflects the fact that they are recycled existing fibres. The raw material comes from many different sources and will have been used for a variety of different applications. This means that the thermal bonding process will not bond the fibres as tightly and strongly together as with virgin fibre.

However, because the raw material is recycled, environmental sustainability benefits as well as cost savings can be achieved.

These fabrics are used as carrying and strengthening layers within manufactured waterproofing membranes and can be produced in different densities, roll sizes and colours, depending on the client’s specification.
We can offer virgin fibre or recycled polyester materials with yarns of different gauges, compound matting made from recycled fibre, or Glass Tissue Fibre in varying grades.

Wallbarn offers many different solutions in the field of geotextiles. We operate a very adaptable factory production line, and offer short lead times. All our products comply with the highest technical quality control standards, and we can fit our processes to match your requirements.

7mm pads for paving and timber decking

Wallbarn has just launched a new pad for paving and decking.

Often on refurb projects the height threshold is very limited. Drainage is assured as the upper side of the pads have drainage channels and the rubber material means that these pads can tolerate very high loads without risk of damage to the deck beneath.


They are supplied complete with positioning lugs fixed to the centre of the pads. Wallbarn can supply units suitable for paving or for timber decking.

Introducing the Biodiverse Green Roof

There has been much confusion previously regarding the difference between biodiverse roofs and brown roofs and we are here to help explain some of the fundamental differences between the 2.

To help highlight the differences:

  • Biodiverse roofs are where seed or plants are introduced into the substrate at the time of construction.
  • A brown roof is where the substrate surface is left to self-vegetate from windblown and bird lime seed dispersal.

Increasing Popularity

Biodiverse green roofs have become an increasingly popular variety of roof garden finish in recent years as they are seen by many planners as a more natural, rugged Biodiverse Green Roofurban feature and can offer a greater diversity of species as well as prolonged foraging for insects.

The Concept of the Biodiverse Roof

The concept behind a biodiverse roof is that a plain, low nutrient environment is created at roof level and a small selection of hardy plant species are introduced to give a moderate level of cover and help bind the whole system together.

Once this has been established, tough, hardy plants will be introduced to the area naturally and start to germinate in the substrate, replicating natural wild urban spaces that are found at ground level.

The substrate level is normally up to 150mm, which offers a medium weight build-up, usually no heavier than 120kg per m2

Minimal Maintenance Required

A significant benefit offered by the installation of biodiverse roofs is the fact that they relatively little maintenance. On top of this, they still offer sound acoustic and temperature insulation properties to the building, and will help to attenuate water runoff from the rooftop to a significant degree.
Often objects such as rotting tree stumps, stones and rocks can be introduced onto the area to encourage insects and other wildlife.

Waste material from the construction process, such as crushed aggregate and concrete, can be introduced into the substrate, adding to a sense of recycling elements of the project.

Wallbarn M-TRAY can be produced as biodiverse modular roof system by adapting substrate and vegetation type to suit the project requirements.

Even The Biggest Companies are Going Green

One of the world’s biggest companies is leading the way when it comes to creating a positive, fun-filled, colourful working environment with aims of inspiring and innovating both staff and visitors alike.

Microsoft’s Building B44 in Redmond, Washington has recently completed a huge redevelopment project and now has a 35-foot living wall with over 36 plant species coupled with a three-story spiral helix staircase makes a dramatic welcoming reception area, while interactive artwork throughout creates a unique environment of engagement, and a creative home for Microsoft’s Cloud & Enterprise team.

Green Roofing Benefits

Along with providing significant aesthetic benefits, the installation of a green roofing system to a building or property has every chance of proving itself to be a very Recycled Polyester Geotextile Fabrics 4worthwhile investment, rather than just an expenditure.

Read on to find out why this is:

Winter Savings – During the cold and wet winter months, the installation of a green roof can help to improve insulation by as much as 25% in dry conditions. A green roofing system can also raise the outside temperature of the roof by an average of approximately 4.5°C when the weather is cold; whilst  reducing the levels of heat loss due to wind by as much as half.

Figures such as these help to highlight exactly why the reduction in heat loss will help you to save money on your heating bills during the winter.

Summer Savings – On the flip side of the winter benefits, the installation of a green roofing system to a property also offers the ability to keep properties cooler than bare roofs by average of 15°C during warm summer months.

It is far from uncommon for businesses to find themselves spending more on air conditioning bills during the summer than they spend on heating bills during the winter. Therefore if you have the opportunity to make an investment that covers all bases, surely it is worth investigation.
