The Importance of Non-Combustible Pedestals

Designed and manufactured in the UK from stainless steel, our forthcoming range of class A1* rated non-combustible pedestals will help to ensure compliance with new fire safety legislation.

Our range of decking and paving pedestal support systems offer a versatile, durable and cost-effective solution to projects on all scales.

Reacting To Significant Changes

Combustible materials will be banned from the exterior of new residential tower blocks above 18m as well as schools, care homes and hospitals, the government has announced.

Currently, building regulations in the UK state all insulation and filler materials for cladding on high-rise buildings must be of ‘limited combustibility’.

It is understood that the only materials that will now be allowed are those classed as A1 or A2 under the European Reaction to Fire classification system, which includes materials such as metal, stone and glass which rarely contribute to fires, or plasterboard, which makes no significant contribution.

This measure – which was lobbied for by campaigners and the RIBA – will usher in a regulatory change that will signal a major upheaval in the building industry.

Developing A Stainless Steel Adjustable Pedestals

At Wallbarn, we are pro-actively reacting to the changes in fire safety regulations to ensure compliance with our products.

Using stainless steel to ensure extreme temperature tolerance, we are developing this bespoke product from scratch and it will be subject to extensive independent testing to ensure that it is fit for purpose.

Based upon our ASP design to help distribute weight effectively, we are currently developing a stainless steel adjustable pedestal which will be a Class A1 product and which is due for launch in quarter one of 2020.

Offering a similar base to our universal pedestal, we will provide different headpieces for both decking and paving to ensure maximum versatility.

What Are Non-Combustible Pedestals?

After the tragic events at Grenfell, new legislation was introduced on 21st December 2018 which specifically relates to the fire requirements of external balconies in England and Wales. and one of the keys to this is the need for non-combustible decking pedestals in some construction projects.

Previously viewed as specialist products, non-combustible pedestals and pads are now going to be essential to ensure compliance with fire regulations affecting the construction industry which have become significantly more stringent.

What Has Changed?

For the first time, balconies are now counted as part of the external wall and classified as a “specified attachment”. For building works which commenced after 20th February 2019, the following now applies:

The construction of either:

new buildings which are:

  • over 18m, and
  • in which people sleep; or

for the refurbishment of existing buildings where:

  • changing the cladding would result in lower safety (i.e. recladding over concrete), or
  • the building is changing in use

then the new legislation indicates that all components of the wall must be individually tested as non-combustible (European Classification A2-s1, d0 (limited combustibility material) or A1).

Significantly there is no longer the ability to test a complete wall (or therefore balcony) system using BS8414.

General Benefits of Green Roofs – Reduction of Urban Heat Island Effect

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

Green roofs are recognised to have a positive effect on reducing the UHIE (Urban Heat Island Effect)

What Is The Urban Heat Island Effect?

An urban heat island, or UHI, is a metropolitan area that’s a lot warmer than the rural areas surrounding it. Heat is created by energy from all the people, cars, buses, and trains in big cities like New York, Paris, and London. Urban heat islands are created in areas like these: places that have lots of activity and lots of people.

There are many reasons for UHIs. When houses, shops, and industrial buildings are constructed close together, it can create a UHI. Building materials are usually very good at insulating, or holding in heat. This insulation makes the areas around buildings warmer.

“Waste heat” also contributes to a UHI. People and their tools, such as cars and factories, are always burning off energy, whether they’re jogging, driving, or just living their day-to-day lives. The energy people burn off usually escapes in the form of heat. And if there are a lot of people in one area, that’s a lot of heat.

How Can Green Roofs Help?

For more information, please click here

A green roof, or rooftop garden, is a vegetative layer grown on a rooftop. Green roofs provide shade and remove heat from the air through evapotranspiration, reducing temperatures of the roof surface and the surrounding air. On hot summer days, the surface temperature of a green roof can be cooler than the air temperature, whereas the surface of a conventional rooftop can be up to 90°F (50°C) warmer.1

Green roofs can be installed on a wide range of buildings, from industrial facilities to private residences. They can be as simple as a 2-inch covering of hardy groundcover or as complex as a fully accessible park complete with trees. Green roofs are becoming popular in the United States, with roughly 8.5 million square feet installed or in progress as of June 2018.2

Offsetting The Urban Heat Island Effect

Green roofing systems, such as the M-TRAY® green roofing system, can also help to offset the urban heat island effect. Because cities are full of roads, roofs, and parking lots, they tend to absorb a lot of sunlight, making them several degrees warmer than the surrounding country. By putting a green roof in place, you can help to offset this effect and start to cool your city back down again to a more reasonable temperature.

Green roofs can absorb both dust and pollutant gases and also offer water attenuation qualities (up to 50% at 100mm depth). They also cool buildings rather than having the hard surfaces radiate heat out at night. There is also evidence of localised cooling, storm water reduction, less flooding and more insects and wildlife in urban centres.

Introducing The M-Tray®

Wallbarn presents the new M-Tray® for 2019 which 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

Our bespoke design allows us to supply the best quality vegetation to site. The fully established, mature sedum or wildflower plants, are contained within easy-to-carry trays which click together to form an almost invisible join.

Inverted Roofing Systems Explained

An image of an inverted roof|An image of an inverted roof installation|An image of an inverted roof installation|An image of a completed roof installation|An image of an adjustable pedestal

Offering a wide variety of benefits, inverted waterproofing systems are an alternative to the warm roof method.

Typically defined as a type of roof which has the waterproofing layer beneath the insulation rather than above it, inverted roofs require the insulation to be ballasted to prevent wind uplift or floating in rainfall water.

Often referred to as an “upside down” roof, the requirement for increased thickness of the installation board means designers need to be sure that sufficient weight is placed on the boards to prevent movement.

Concrete paving slabs offer a good ballasting solution. To prevent damage to the rigid installation board, the slabs should be suspended onto pedestals.

Wallbarn’s range of pedestals will separate the slab from the deck, create an air gap beneath the slab for effective roof drainage underneath and between the slab and the positioning lugs create uniform straight paving lines drainage.

The Benefits of Inverted Roofs

Benefits of inverted roofs include

  • The waterproofing layer is protected
  • The functional life can be considered to be significantly longer
  • Improved environmental performance
  • Thermal shocks are among the most important factors involved in ageing and fatigue for waterproofing membranes which is not the case for inverted roofs.
  • Better stormwater management
  • Flat roofs can be constructed to offer full and easy access for any future work
  • They can withstand surface traffic
  • They remain unaffected by freeze/thaw cycles

Durable, Cost-Effective Products

Offering a durable, cost-effective range of products, our pedestals offer the ideal solution for anyone looking to create a suspended system for their inverted roof which allows easy access to the concealed surface beneath.

More roof and balcony designs incorporate a completely flat upper surface in order to utilise them more effectively as leisure areas. More attractive paving with spirit-level-flat finishes can be achieved using a much larger variety of different stone and slab shapes using our ASP supports.

Wallbarn’s range of adjustable support pads ensure that even where contractors build their roofs to a fall to allow good drainage, a completely flat upper level of paving or decking can be achieved.

How Does The Process Work?

Very small, irregular or multiple changes in height can be accommodated using the simple but durable twist mechanism on the stem. Once the slab is placed on top of the support, the whole system locks into place.

Falling roofs can be paved to an even finish extremely quickly and effectively using these supports, cutting down labour time considerably. Edges and end of runs can either be bordered with a line of washed pebbles or by removing the lugs and sliding the support underneath the slab and out of view. Services such as cables or water pipes can be laid underneath the slabs easily, keeping the upper surface uncluttered.

Wallbarn adjustable pedestals are available from 10mm to 1020mm. Ultra low and very high height thresholds can be accommodated.

All Wallbarn adjustable pedestals are extremely durable and have been tested and found to be working normally at minus 40 degrees Celsius.

The range of support pedestals has been created to effectively address all potential installation scenarios and form the core of our product range.

Stay tuned for details of the MetalPad…….

What do A1 and A2 ratings mean?*

The government’s official guide to rules on fire safety – Approved Document B – defines products achieving an A1 classification as non-combustible and products achieving an A2 classification as being of limited combustibility. A-class products – those classified A1 and A2 – make no significant contribution to fire growth while products with a rating of B-F are classified as combustible.

The European Classification system for combustibility classifies construction products using a series of tests. Class A materials have the best performance in a fire and are divided into two sub-classes, Class A1 and Class A2.

Class A1 – Products are described as having no contribution to fire at any stage. The BS EN 13501-1 test sets several thresholds for combustion performance when tested to both EN ISO 1716 and EN ISO 1182. One of these thresholds is a maximum heat of combustion of 2MJ/kg. Typical products meeting this classification include most inorganic materials such as metal, stone, and glass.

Class A2 – Products are described as having no significant contribution to fire at any stage. BS EN 13501 sets several thresholds for combustion when tested to EN ISO 1182, or both EN ISO 1716 and EN 13823. One of these thresholds is a maximum heat of combustion of 3MJ/kg. A typical product meeting this classification is plasterboard.

An A2 certified product has higher combustibility and can sustain flame for no more than 20 seconds. In contrast, A1 has lower combustibility and no sustained flaming when tested.

How Green Roofs Can Help To Combat The Dangers of Flooding

Spring and summer have been among the wettest on record in eastern North America. And the world is watching Houston this week, where the remains of Hurricane Harvey have caused devastating flooding.

Rainfall amounts in the spring broke records in places like Toronto, where 44.6 millimetres of rain fell in 24 hours. The downpours earlier this spring caused the stormwater infrastructure in Canada’s biggest city to overflow, leading to flooding of busy downtown streets.

Rapid Loss of Permeable Surfaces

Urbanisation in many North American cities has led to a rapid loss of permeable surfaces where water can freely drain. Coupled with the growing downtown core population in cities Toronto, this means that the stormwater and sewer systems in place must manage more water than in previous decades.

Furthermore, global temperature increases have been linked to the rise in extreme weather events worldwide, a trend that could worsen if global warming is not brought under control.

Many cities are ill-equipped to deal with these unprecedented amounts of precipitation due to their insufficient and outdated stormwater infrastructure.

Using Green Roofs To Help Manage Storm Water

Green roofs are a green infrastructure (GI) option that can be applied to virtually any rooftop given weight load capacity. The benefits of green roofs extend far beyond their obvious aesthetic appeal.*

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 form 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
    • Increasing value of the development
    • Properties with green roofs sell / rent faster rate than naked buildings
  • Making the planning process easier
  • Money saving

To help with this, Wallbarn presents the new M-Tray® for 2019 which has been further improved to make sedum roofs easier to install with less disruption to both the plants and the structure.

Our bespoke design allows us to supply the best quality vegetation to site. The fully established, mature sedum or wildflower plants, are contained within easy-to-carry trays which click together to form an almost invisible join.
