Native Wildflower Green Roof

An image of a wildflower green roof

As well as the sedum trays, Wallbarn plants up a wildflower mix into the M-Tray®. We have developed a new native wildflower green roof which was planted at the end of last year and will be ready for dispatch and installation this summer.

Wildflower green roofs contain a mixture of native flower species to attract native insects and birds.

A varied mix of at least six different native species has been selected. All these flowers and herbs are low growing, hardy species, chosen to be pollinators for butterflies and bees.

The ideal way to introduce wildflower seed mix

In order to get more wildflowers into the system, Wallbarn has developed wildflower green roof trays with a wildflower seed mix at the point of harvesting and packing.

This seed mix is designed to attract bees and butterflies, so will increase the biodiversity and environmental impact of the roof.

Wildflower green roofs still require maintenance

There are certain things to consider: these flowers are chiefly annuals, so will die off at the end of the growing season.

Therefore, in order to have flowers the next year, the roof will need to be reseeded. Users can harvest the seeds in this season’s crop to sow the next year, or purchase another seed mix (available from Wallbarn) the next spring.

Also, these wildflowers can grow very high, up to 80cm and will have much more fibrous structures than sedum (which is succulent) so the dead stalks and other vegetation will not rot but remain on the roof after the flowers have died off.

This makes the roof look unsightly and is also a potential fire risk, so these dead stalks should be removed every autumn. Clients should bear this additional maintenance in mind when choosing wildflower – if the roof is inaccessible this can prove a major problem. The additional costs of more maintenance should also be factored.

Find Out How Green Roofs Can Transform Almost Any Lost Space

Whilst the name ‘green roofs’ will undoubtedly make many people look to the skies as they automatically think of the building rooftops, the versatility of the M-Tray® ensures that they are suitable for a wide variety of open and lost spaces, regardless of size, with some projects taking place much closer to the ground!

One of our previous projects resulted from a request from a residential customer who wanted to ensure that a recently installed garden storage unit on the back of his home was more attractive.

By giving it a green roof. The M-Tray®, being modular in shape and incredibly easy to install, lent itself perfectly to the job.

Providing Easy Access

The green roof components needed to be walked through the house to access the garden. Traditional roll-out green roof systems, with their bags of aggregate-based substrate and sedum blankets spilling compost and plant matter, are extremely messy to transport and install.

The M-Tray® is self-contained within the walls of the plastic tray and comes with fully established, sustainable vegetation.

Taking a closer look at the M-Tray®

Our M-Tray® modular green roofing system has been further improved to make sedum roofs easier to install with less disruption to both the plants and the structure. M-Tray® is also designed to give a more seamless, verdant finish and an instant green roof.

Wallbarn is at the forefront of developments in the green roofing sector and has always provided products that combine top-quality ingredients with user-friendly, hassle-free maintenance. The purpose of M-Tray® is to enhance rooftop living.

What makes the M-Tray® green roof unique?

  • Mature, established vegetation
  • Click-together trays create a seamless connection
  • Easy to transport and install
  • Specially-mixed substrate for the longevity of plant life
  • 100mm deep cavities for healthy roots
  • Optimum drainage means stronger plants
  • No sharp edges or mess meaning minimum disruption to plants, deck structure and inhabitants!

3 Key Benefits Offered By A Green Roof Installation

A close-up of completed M-Tray green roof installation|An overhead shot of a green roof

With the concept of ‘the green roof’ now widely acknowledged throughout many areas of the world, we believe that now is a great time to highlight some of the most important benefits offered by the installation of a quality modular green roofing system onto a property.

Below we have identified 3 of the primary benefits available:

Benefit No. 1 – Positive Environmental Impact

Green roofs are proven to have a positive impact on the environment in that they help reduce carbon dioxide concentration as grass and other vegetation aid in air purification. The air around most urban centres is most toxic because very few trees or grass are present. However, having some vegetation on every apartment’s rooftop can help deal with the toxic air.

Another key benefit of using a green roof is that it helps conserve heat by reducing heat loss during winter and reducing heat absorption into the house during hot weather and summer.

These roofs have also shown the ability to reduce stormwater runoff. Stormwater is often destructive as it carries away anything in its way, as well as damaging waterways. These roofs, however, retain water reducing its speed and impact on these waterways.

For more on the positive environmental impact created by the installation of a green roof, please check out this study by NC State University by clicking here.

Benefit No. 2 – Prolonging the life of your roof

Green roofs last many times longer than roofing shingles exposed to UV rays. The grass and soil covering the waterproofing membrane protect the roof from harmful UV rays that cause faster degradation especially on conventional roofs.

If installed correctly, these roofs can last twice as long as the most durable roofing materials in the market today. Little or no maintenance is required for these roofs thus making them cost-effective and value for your money.

Please Note – With new advances in green roofing technology, the plants are far more likely to survive and not die back as they are more mature and established

Benefit No.  3 – Reduction in energy costs

Unlike traditional roofs, green roofs offer the chance to reduce your energy bills by absorbing heat, therefore providing natural insulation for buildings.

According to a study conducted by the National Research Council of Canada, even a six-inch extensive green roof can reduce summer energy demands by more than 75 percent.

Huge Variety of Options

The horticultural options are vast. Sedum, exotic grasses, ferns, ivy and herbs are the most common plants used. We aim to get a fair mixture of vegetation to ensure a diverse mix of textures, colours and flowers across the year.

We design the planting so that shade-loving plants are respected, nothing gets overrun by aggressive species, those requiring higher or lower amounts of water and additional feed are planted in the correct place, and an overall pattern is attractive, both close up and from a wider viewpoint.

As well as the sedum trays, Wallbarn plants up a wildflower mix into the M-Tray®.

A varied mix of at least six different native species has been selected. All these flowers and herbs are low growing, hardy species, chosen to be pollinators for butterflies and bees.

Do Green Roofs Offer Noise Reduction Qualities?

M Tray installation through a window|The M Tray Modular Green Roof

A close-up of an M-Tray installation in Whitstable

Green roofs have increased dramatically in popularity in recent times, thanks in large part due to the number of ecological and economic advantages they offer.

These include:

  • Increased thermal insulation
  • Floodwater management
  • Improved air quality
  • Enhanced biodiversity

However, did you know that green roofs can also be effective at reducing noise?

Noise reduction qualities

Green roofs have important acoustic benefits as well. A study has shown that:

“Because the typical substrates used for green roofs are (highly) porous and thus allow sound waves to enter the growing mediums. Because of the large number of interactions between sound waves and substrate particles, attenuation occurs. As a result, less noise will reach the back façade or the roof apartment compared to the situation with a non-vegetated roof that is most often made of highly reflective material (e.g. concrete).”

Please click here for more on this study.

Taking a closer look

Zaloa Azkorra, an agricultural engineer of the UPV/EHU-University of the Basque Country, is currently conducting some fascinating in-depth research at the University School of Mining and Public Works Engineering into the benefits provided by green walls.

The researcher has concluded that walls comprising plants offer great potential for absorbing noise and could be used as acoustic insulation.

Temperature & acoustic benefits

The researcher is proposing that green walls be used in buildings, inside and outside, as they can improve the temperature and, what is more, they can achieve acoustic improvements. Furthermore, “they are attractive and cool,” said Azkorra. But she also admitted at the same time that having such systems is costly and that, what is more, the systems need to be improved. As Azkorra pointed out, “apart from having plants on the walls, they have to be maintained and that is quite expensive”. So right now she sees no alternative but to fit them in special buildings.

Now that the plant modules have been cultivated, she has begun to carry out thermal studies on them to study what benefits they can bring from the temperature perspective.

With dimensions of 500mm x 500mm x 100mm (4 per square metre), the new M-Tray® modular green roofing system has been designed to significantly improve the ease of installation.

Easy Estimates & Installation

Exactly 4 units per m² make estimating and installing much easier. M-Tray® modules are extremely easy to transport and deliver. They can also be used in areas where standard roll-out is not possible.

They are easily transported to the site by pallet and can then be stacked neatly onto a parcel trolley. Each M-Tray® unit is self-contained and needs no additional aggregate which means zero disruption, zero mess. 

Perfect For Difficult To Access Areas

During installation at the Radisson Blu Hotel, Heathrow, access to the roof was through a busy working hotel which could have been an issue were it not for the highly portable shape of our specially-designed M-Trays®.

During a previous installation at the Radisson Blu Hotel, Heathrow, access was a major issue to this hotel project and a roll-out green roof system was impossible due to the fact that much of the materials had to be moved through the building, a working hotel.

A Viable Solution

Our M-Tray® modular green roof system modules were really the only currently viable solution as the planted units could be walked through the lobby where required and hand-balled onto the roof structure.

The easy-to-fit modules were connected together using the specially designed fittings and the whole green roof was constructed within one day.

The hotel guests, who had previously been overlooking a flat roof with a black bitumen surface, now had a live, growing, green rooftop view from their rooms.

The Key Advantages of the M-Tray® Modular Green Roofing System

Modular systems are much more convenient and are faster and future proof compared to roll-out green roof systems.

  • Deeper cavities for extra root growth
  • Optimum drainage leading to stronger plant growth
  • More established vegetation at point of installation
  • More efficient transport and packaging
  • Exactly 4 units per m²
  • Easier to carry trays with smooth handles
  • A closer connection between trays ensures more seamless plant growth
  • No sharp edges ensure reduced risk to the membrane
  • Nothing spills out, less mess
  • Made from recycled plastic with a recycled substrate
  • Less packaging means less waste
  • UK designed and manufactured

Slip Resistant Decking – Perfect For Poolside Installations

Enhancing Your Outdoor Space With Hardwood Decking

One of the primary concerns relating to the installation of a new outdoor decking system relates to safety, especially when the completed deck is located near to a swimming pool, jacuzzi or near the beach and therefore likely to come into regular contact with water.

Creating a Slip Resistant Finish

iDecking have spent many years perfecting an innovative, environmentally-friendly, non-splinter timber decking solution offering all the good looks of the real thing but without the flaw of other products. 

Unlike many other traditional decking materials, the systems which have been developed by iDecking, completely waterproof your deck or roof deck area with an attractive, durable and slip-resistant finish.

Offering Further Evidence

To help offer further evidence relating to the slip resistance of the iDecking boards, we have carried out some slip tests on our decking products recently. The tests are carried out according to BS7976 -2 Pendulum Slip Test.

The test is carried out via a pendulum testing machine in at least 2 directions, both in a dry state and in a wet state. The results are as follows:

Selecting The Correct Products

It really is not possible to over-emphasise the importance of choosing a decking product which offers the longest lasting and safest solution for the particular project. Designers should always be aware of the uses on schemes which they are specifying and therefore select the correct decking products accordingly.

With a number of cheaper, inferior products on the market, it is essential that designers and installers choose products which are specially designed and selected to fit the purpose of the project. Thankfully, the range of iDecking products ticks all of the right boxes.

Composite decking is widely accepted to be one of the most effective decking products available due to the fact that it boasts a number of qualities highlighted by a longer lifespan than traditional wood.

Introducing Eco-Friendly Composite Decking

Whilst many of the old composites were made from sawdust mixed with cheap polymers, so they absorbed a lot of moisture. They were also susceptible to attack from insects, mildew, turned green and very slippery over time and were also prone to rotting due to the high wood fibre content.

However, the introduction of the iDecking Revolution products offers a new generation of materials which have been developed to look and perform much better in the long term.

Developed by iDecking Revolution, DURO is a brand new material which has been developed with the following goals in mind:

  • Fast and easy installation using no screws
  • 100% Eco-Friendly
  • Ultra-Low Maintenance
  • Custom Colours

Exceptional Durability

These new systems offer a new mindset for artificial decking. They will not fade significantly, absorb hardly any moisture and do not swell or split. In addition to this, any scratches or blemishes can also be sanded down to almost French-polish the scratches out, since it is solid throughout, ensuring that long term maintenance is possible and effective.

These products are high end, top quality materials, and are designed to ensure that they do not fade significantly. Essentially, they are in many ways better than tropical hardwood. Despite its formula being kept as a secret, DURO’s main ingredient is Rice Husk; a by-product in the processing of rice. This husk, when blended together with virgin polymers, makes it an incredibly versatile, strong and durable material.

How To Install Hardwood Timber Tiles On Roof Terraces

An image of a completed timber decking tiles installation

Tropical Hardwood tiles for suspended decking solutions on flat roofs, terraces and walkways.

Natural, Attractive Finish of Timber Decking

By using suspended Wallbarn Timber Paving Tiles, installers combine the natural, attractive finish of timber decking with the speed and ease of laying paving slabs.

Traditionally laying timber decking directly onto these deck surfaces led to additional costs of employing specialist carpenters. Laying timber joists directly onto the waterproofing membrane also risked damage over time. Wallbarn Timber Paving Tiles offer the ideal solution. The weight of the tile will hold the system in place.

Suspended System

This suspended system avoids having to fix anything onto the deck and lifts all the timber away from any standing water, avoiding the dangers of a slippery surface.

As everything is free-standing, the tiles can be taken up and replaced without disrupting the whole area, should the deck need to be inspected. Unsightly items such as drainage outlets, cables and pipes can be hidden beneath the tiles and accessed easily.

Achieving Stunning Finishes

Stunning finishes can be achieved. The tiles can be laid in a straight line pattern or in a “chessboard” style, depending on the client’s wishes. We have a range of different timber available sourced from South America, chosen for their beauty and durability including Ipe and Cumaru. We can also supply FSC® certified timber as we have FSC® Chain of Custody (please speak to your Wallbarn representative).
