How Much Do You Know About The Products You Are Using?

22-30mm Minipad for Paving

Inferior plastic will crack in sub-zero temperatures. So if your project requires the installation of decking supports or paving supports, what steps are you taking to ensure that you have a quality product?

With potentially catastrophic safety issues should any product fail to function once installed, it is absolutely essential that before purchasing a product, you can be certain of its qualities and durability.

Cutting No Corners

Some manufacturers use fillers in order to save money – this can weaken the structural integrity of the pedestals but this is not the case with anything available from the Wallbarn product range. We do not cut corners and it is very important that you do not either when creating or retro-fitting a raised deck.

Independent Testing

Taking Steps To Become Carbon Neutral

An Aerial Shot of Bournemouth

“AMBITIOUS” plans for how BCP Council will become carbon neutral by 2030 have been outlined in a new action plan.

Wide-ranging recommendations

More than 150 measures are outlined in the draft strategy which will form the basis of public consultation, should it be backed at Tuesday’s meeting of the council.

They include the possibility of introducing a congestion charge, encouraging the use of electric and hydrogen-powered taxis and purchasing land for “large-scale renewable energy installations”.

“We are uncertain of the full extent that the effects of climate change will have on our area but know it will be more severe if we do not act now,” a report published ahead of the meeting says.

“Non-achievement of our declaration commitments will contribute to a further degraded and hostile global environment with local consequences.”

Publication of the plan

Publication of the action plan follows the July decision of the council to declare a climate and ecological emergency and its subsequent pledge to be carbon neutral by 2030.

It also promised to work with organisations and people to help the whole area reach a “net-zero position” ahead of the 2050 target set by the government.

The council is responsible for just under 20,000 tonnes of carbon dioxide emissions every year – about one per cent of the total for the area.

Most of this comes from its direct burning of fuel, such as petrol in cars, and through its use of electricity.

Including green roofs

We were delighted to see that one of the measures outlined in the extensive plans relates to an increased focus on installing green roofs.

‘Seek to promote the development of green roofs and walls, street trees and urban greening.’

8 Areas For Consideration When Planning a Green Roof Installation

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

When planning a green roof, there are a few things you need to think about prior to installation and below, we have identified 8 of the key areas for consideration during the planning process.

No. 1 – What is the load of your structural support?

Every structure will have a maximum weight it can support so this is extremely important to know and workaround. Remember to allow for snow loading and unseasonal rainfall in weight calculations, as the green roof could hold/absorb considerable additional weight during high precipitation.

No. 2 – Roof pitch for optimum drainage

it is very important that your roof allows for free drainage into suitable drainage outlets so the plants do not become waterlogged. A well-designed green roof can be a tremendous asset to a building with terrific insulation properties, helping to keep it cool in the summer and warm in the winter, which in turn helps to reduce your building’s heating and cooling bills. Our modular green roof can be installed on roofs pitched at an angle of up to 15 degrees.

No. 3 – Light & wind

Most sedum plants require direct sunlight or, at worst, semi-shaded conditions. They will not survive long-term in very shaded areas. Equally, areas of high wind or saline conditions will affect the type of plants you can use, so care should be taken to ensure the species are suitable for the conditions.

No. 4 – Purpose served by your green roof

is it simply for environmental purposes or do you wish to create a space which you can enjoy to the full? Are you seeking colour? Year-round greening? Bio-diversity?

No. 5 – Maintenance & irrigation

Green roofs will require some maintenance at least twice a year and during periods of very high temperatures and no rainfall.  irrigation is recommended. Try to allow for this in your plans.

No. 6 – What look are you hoping to achieve with your green roof?

Green roofs can be aesthetically pleasing to a building’s inhabitants and visitors and really can help to lift a neighbourhood. So it is important to think about how you want your green roof to appear from the outset. Would you prefer just a sedum roof – albeit containing several varieties of sedum – or one with wildflower sown with the sedum? Do you want an aluminium edging surround? And a pebble surround? These and other accessories might be considered.

No. 7 – What budget do you have?

The creation of a green roof is initially more expensive than traditional roofing materials but there are many benefits to make up for it. The savings to the environment and on energy costs can be tremendous over time. The price you pay will largely depend upon the style of green roof you opt for.

Pitch – if not a flat roof, consider your roof’s pitch…

No. 8 – What is the level of required access?

Although all green roofs need to have some access for maintenance purposes, some of them really are rooftop gardens and there for the family to enjoy. You need to think about how much access will be needed when you start on your green roof design.

After answering all of these, questions you will have some idea of the best design for a green roof on your property. They are becoming increasingly popular and can provide a fabulous feature for your property just so long as you have thought things through properly.

New Green Roof Legislation is Coming To New York

New York

Two laws requiring new property owners to build solar panels or green spaces on their roofs went into effect on Nov. 15 — marking a major step towards Brooklyn’s environmental sustainability, according to local green thumbs.

“It’s important and very valuable,” said environmental activist Pete Sikora from the New York Community for Change, a local nonprofit. “It’s a critical step for New York City to meet the Green New Deal goals.”

New Legislation For Developers

The legislation — which Councilman Rafael Espinal (D-Bedford Stuyvesant) first introduced to the City Council in July of 2018 — requires developers to install either solar panels, greenery, or a combination of the two on all new roofs.

The mandate exempts very slanted roofs and roofs that already contain structures, such as water towers, greenhouses and other equipment, according to a representative from the Mayor’s Office of Sustainability. Low-rise residential buildings with less than 100 square feet of available space and other types of buildings with less than 200 square feet will also be exempt, and the sustainable measures won’t take the place of recreational spaces that are integral to the building’s use, such as playgrounds on school roofs or terraces on apartment buildings.

Not Limited To New Roofs

The laws also apply to property owners seeking to renovate their roofs, including the owners of historic buildings — who will have to take their green roof plans to the Landmarks Preservation Commission before obtaining a construction permit from the Department of Buildings.

Environmental officials say that property owners will be in charge of funding and maintaining solar panels — which is no cheap task. The average solar panel array costs about $30,000, but since the panels power the building, the electricity generator eventually pays for itself, according to the executive of a solar panel company.

“Any time you’re not buying power from Con Ed, you’re saving money,” said TR Ludwig, the CEO of Brooklyn Solarworks, who said that it usually takes homeowners four to eight years to pay off the price of the panels before they have free energy.

Significant Tax Incentives Available

Building owners will also receive significant tax incentives for the solar panels, getting back 20% of the equipment costs in the form of a property tax abatement, and receiving a $5,000 tax credit, among other pluses, Ludwig said.

Greenery, which helps reduce flooding and provides better building insulation, is significantly cheaper, costing between $10 and $40 to install per square foot, the New York Times reported. The gardens require some maintenance, like periodic weeding, although they don’t need to be watered frequently.

Could Urban Forests Soon Be Introduced To Paris Landmarks?

Paris, France

The city plans to fill some small but treasured sites with trees—a climate strategy that may also change the way Paris frames its architectural heritage.

Some of Paris’s most treasured landmarks are set to host the city’s new “urban forests.”

A New Plan

Under a plan announced last week by Mayor Anne Hidalgo, thickets of trees will soon appear in what today are pockets of concrete next to landmark locations, including the Hôtel de Ville, Paris’s city hall; the Opera Garnier, Paris’s main opera house; the Gare de Lyon; and along the Seine quayside.

Creating An Island of Freshness

The new plantings are part of a plan to create “islands of freshness”—green spaces that moderate the city’s heat island effect. It also falls into an overall drive to convert Paris’s surface “from mineral to vegetal,” introducing soil into architectural set-piece locations that have been kept bare historically. As a result, the plan will not just increase greenery, but may also provoke some modest rethinking of the way Paris frames its architectural heritage.

The trees in this rendering of Paris’s Opera Garnier would take the place of an existing bus parking. ( Ville de Paris/Apur/Céline Orsingher)

While “forest” might be far too big a term for plots this modest in size, the plans as a type are necessary if Paris is to meet its ambitious greening goals.

Ambitious Plans

By 2030, city hall wants to have 50 per cent of the city covered by fully porous, planted areas, a category that can include anything from new parkland to green roofs. This means that, when it comes to planting, pretty much any urban space needs to be up for grabs.

Can a ‘green roof’ strategy could reduce the impact of excess rainfall?

A close up image of a green roof installation

A green roof strategy could help cut the negative impact caused by severe storms and flooding, studies have shown.

Effective Protection Against Excess Rainfall

A study by the United States Environmental Protection Agency has taken a closer look at the way green roofs can effectively combat the threat posed by annual rainfall.

“Results indicate that the green roofs are capable of removing 50% of the annual rainfall volume from a roof through retention and evapotranspiration. Rainfall not retained by green roofs is detained, effectively increasing the time to peak, and slowing peak flows for a watershed.”

“There are seasonal considerations as more runoff is generated during winter and for many summer storms, there was no runoff. Green roof runoff does contain concentrations of some nutrients and other parameters, but values are in line with other planted systems. Due to the volume reduction, actual nutrient loadings from green roofs are less than asphalt roofing runoff or otherwise manageable at the downspout.”

Amazing Results

Researchers at Newcastle University compared the effectiveness of urban green infrastructures such as green roofs, ponds, and water channels with traditional engineering measures such as culverts or flood walls in reducing disruption during extreme rainfall events such as ‘Thunder Thursday’. They found that greening every roof in the city could reduce travel disruption by over 25%.

Green infrastructure uses natural processes to store rainwater and decrease the amount released on roads and pavements.

As a result, the depth of flooding is reduced which can make its impact more manageable.

Richard Dawson, professor of earth systems engineering at Newcastle University, said: “We saw on Thunder Thursday the massive amount of damage and disruption that flooding can have on our transport networks.”

Additional Benefits of Green Roof

Along with this huge benefit, the installation of a green roof also offers the following benefits to the property and the surrounding area.

The benefits of constructing a green roof include:

  • Improving the local environment by providing wildlife habitats
  • Absorbing CO2, pollution and particulates from the atmosphere
  • Improving sound and vibration insulation
  • Improving thermal insulation
  • Reducing the amount and speed of rainwater run-off by around 50% and forming part of a SUDS design
  • Reducing the “heat island” effect in built-up areas and helping to improve air quality and environment
  • Protecting the structure and waterproofing membrane from:
    • UV light and heat from the sun
    • impact and abrasion
    • environmental elements including extremes of temperature
    • plant and bird infestation
  • Ballasting inverted waterproofing systems
  • Optimising the structural footprint by:
    • Increasing space – providing new and attractive natural amenity areas
    • Adding floor space in often high-density developments
    • Adding focal points
    • Decreasing energy costs
    • The increasing value of the development
    • Properties with green roofs sell/rent faster rate than naked buildings
  • Making the planning process easier
  • Money-saving

Working With Ultra-Low Thresholds

22-30mm Minipad for Paving

When faced with tight height thresholds during the installation, standard adjustable pedestals can prove to be difficult to work with due to the limited space available.

Because of this, working with feedback from our customers who needed an effective solution to restricted space areas which still required minor height alterations to achieve completely flat surfaces, Wallbarn developed the MiniPad.

The Smallest Adjustable Pedestal in the UK

We believe that the 10-20mm universal pedestal the smallest fully adjustable pedestal on the market in the UK allowing for use with ultra-low thresholds.

Allowing installers to achieve millimetre precision with our pedestals, the MiniPad decking and paving pedestal can cope with falls in more than one direction and accommodate large drops and channels.  


Have an ultra-low threshold? Try our Minipads range. Our time-saving alternative to fixed height pads and perfect for overlaying and retro-fitting. Available from 10mm to 40mm in just three products:

  • 10-25mm
  • 22-30mm
  • 28-40mm

Product benefits:

  • Achieve precise, split-millimetre accuracy in the height of the pedestal to accommodate tiny changes in the level.
  • Designed for use when working with very tight spaces
  • The thread allows 5mm of change to the level
  • Further 5mm extension plate which is fitted to the bottom of the pedestal
  • 5mm extension plate turns 10-15mm pedestal into a 15-20mm fully adjustable pedestal for use in tight spaces

Creating A Suspended Decking Solution

Image of a completed timber decking tiles installation

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.

The Benefits of a 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.

Creating a Stunning Finish

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).
