A Commitment To Quality

Universal pedestals for paving and decking - supporting paving slab underside 2

Depending on how materials are re-processed, it can be impossible for recycled materials to replicate 100% of properties of virgin materials. As such, the degradation of these properties can play a detrimental role with regard to safety factors and durability. 

This is not to say recycled plastics cannot be used in certain applications if the product is structural, a lower strength or safety rating can have very serious implications and this goes a long way towards explaining why some recycled materials often have lower safety ratings.

No Recycled Plastic Used In Our Paving & Decking Supports

With potential long-term viability issues relating to construction products such as decking supports constructed using recycled plastic fibres, we do not believe that there is any margin for error and therefore our range of decking support pedestals are made of virgin fibre injection moulded polypropylene.

Because we cannot guarantee or be assured in any way that the weight tolerances we require of our adjustable pedestals can be achieved by using recycled plastic, we simply cannot use this material.

Our range of decking and paving supports have all been subjected to testing by an independent testing laboratory, some of the most stringent testing available to ensure their qualities.

They are extremely tough and durable. Each support pad (at 35mm and above) able to tolerate the weight of 1,171 kg and tolerate temperatures as low as -40°C and as high as +75°C.

These tests are fully independent and have been created to assess the safety, the strength and the durability of a particular product.

Weight Tolerance* 683kg
Maximum Load* 1,171kg
Max Temperature Plus 75 ° C
Min Temperature Minus 40 °C

 

Take No Chances

Wherever weight tolerance and temperature exposure are of extreme importance, we strongly believe that no risks should be taken with the quality of the products used in the build.

Our products are designed to offer outstanding quality and our range of paving and decking supports offer a variety of key advantages, including:

  • Cost-effective entry-level support pads
  • Separate paving and decking from the base structure
  • Improve drainage
  • Protect surface beneath
  • Avoid the need for sand and cement
  • Easy maintenance – slabs can be removed for inspection or repair
  • Can take up surface easily for inspection
  • Fast & easy installation

* Weight tolerance = the point at which the pedestal ends its normal behaviour and starts to deform (according to an independent testing laboratory test 179112/1)
* Maximum load = the point at which pedestals start to collapse in laboratory tests (according to an independent testing laboratory test 179112/1)

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.

As concerns about climate change and dwindling natural resources grow, green roofs have become increasingly popular throughout the UK.

Offering a variety of benefits

Offering a variety of benefits ranging from the creation of natural habitat to the ability to play a key role within SuDS (Sustainable drainage systems), it is easy to see why so many developers and architects are now factoring green roofs into their plans.

Whilst the concept of green roofs may initially seem a fairly simple one, the benefits offered by the installation of a green roof covers many areas and as such, this excellent article by the team at the ER Group offers an informative take on green roofs for beginners.

Non-Combustible Pedestals For Decking

Fire rated pedestals for decking

 

The industry reaction to the changing legislation relating to requirements for the use of non-combustible pedestals has resulted in designs and specifications which are vague, to say the least.

With claims by other businesses that the headpieces and baseplates used with their ‘non-combustible’ pedestals will be made of rubber, we believe that it is important to ensure that there can be a no doubt whatsoever that our range of fire-rated, non-combustible pedestals will be Class A1 compliant.

All of our products are designed with durability and effectiveness in mind. With such serious consequences should these fire-rated pedestals fail, we strongly believe that there are no grey areas with regards to legislation and no room for interpretation.

As such, we expect to be leading the way with regards to industry innovation in the area of non-combustible pedestals.

Fire rated pedestals for decking

Decking applications

  • Our click-deck headpiece is made from stainless steel, designed to hold a ledged-profile aluminium joist (pictured)
  • The headpiece is coated with RAL 7016 powder-coated paint to prevent reaction between steel and aluminium joist
  • Secure fixing between pedestal head and joist means no need for additional mechanical fixings are required
  • No drilling means less risk of shrapnel or sharp metal objects
  • High weight tolerance and large baseplate mean pedestals can be placed at larger distances apart
  • This means less units per m²
  • Height can be adjusted using adjustable spanner when joist is in place

What Has Changed?

Previously, building regulations in the UK state that any material used for filler or insulation on high-rise buildings must be of ‘limited combustibility’.

However, these regulations will be amended so that only materials classed as ‘A1 or A2’ under the European Reaction to Fire classification system, will be allowed.

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 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, s3, d2 – 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.

Why Do I Want A Modular Green Roof?

Installing Green Roofing Has Never Caused Less Disruption

The concept of the modular green roof is an extension of the standard green roof & at Wallbarn, we specialise in the manufacture and supply of top quality materials that will help you produce a wonderful modular green roof.

Why Do I Want A Modular Green Roof?

Apart from how attractive modular green roofs can look at the seasons’ change, there are other reasons why green roofs are becoming increasingly popular:-

  • The environmental benefits, wildlife, carbon footprint, sustainability etc
  • Building performance enhancements

Our modular green roof module trays are designed with smaller areas & non-professional installers in mind.

Creating An Instant Green Roof

Our M-Tray® green roof system consists of specially-designed modular trays containing superior, engineered substrate and fully established flowering sedum

  • M-Trays® are designed to click together forming a single verdant surface
  • Once trays are connected they start to blend straight away, forming a seamless layer of vegetation
  • Modular M-Trays® can be easily lifted out giving access to the deck without disruption to the rest of the roof

Easy Installation

We supply these as pre-grown units that are very easy to install.

To ensure that any modular green roof supplied by us is as easy to install as possible, the modules are stacked together enabling clean & fast delivery.

The period after installation is absolutely crucial & because our modules are already strong, healthy & well established they are subject to a much smaller risk of wind uplift or erosion in the immediate period after they have been installed.

Another positive of our modules is that if you have any problems with the deck beneath, individual sections can be removed with minimal disruption to the rest of the module.

The Importance Of Effective Green Roof Irrigation

Sedum green roof summer flowers

How important is effective irrigation with regards to an effective green roof installation? For best year-round results, very!

Now, when it comes to green roof irrigation, you should be aware of the fact that the typical installations wouldn’t actually rely on any kind of additional and artificial irrigation. This is mainly due to the fact that the plants and grass used for the instalment are not that water-dependent, and the occasional rain is going to provide them with enough.

However, in cases of prolonged periods of hot weather or in places in which rainfall can be rare, the green roof irrigation has to be thoroughly considered. The most appropriate way to handle the issue and the one which is going to provide you with tons of benefits is the installation of a pop-up sprinkler system.

Supplying a range of irrigation systems

Wallbarn can supply a range of irrigation systems for installation with extensive sedum green roofs as well as intensive roof gardens.

These range from simple timer-based sprinkler networks to fully automated, web-based irrigators, which will feature drought and leak detectors, separate growing zones and control panels. 

The pop-up sprinkler system

A pop-up sprinkler system is incredibly convenient for a wide range of different reasons. Right off the bat, the watering parts of the system are going to stay hidden within the instalment until the time for watering comes.

This is easily programmable through a controlled and unified watering system which is located downstairs, and you could easily adjust it as per the weather requirements.

Furthermore, this is going to spare you all the hassle which is associated with manually watering the green roof.

What Makes Our Fire Rated Pedestal Different?

Class A1 Fire Rated Pedestals

Wallbarn are at the forefront of cutting-edge industry developments and are ready to launch a designed-for-purpose, non-combustible, fire-resistant pedestal on 1st June 2020.

Based upon our ASP (Adjustable Support Pedestal, now known as the Universal pedestal) which is designed to help distribute weight effectively, we have developed a steel adjustable pedestal which will be a Class A1 product.

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

Using galvanised steel to ensure extreme temperature tolerance, we have developed this bespoke product from scratch. We have designed the pedestal ourselves, using our many years’ experience in the paving and decking market and produced a series of prototypes which we have tested extensively; finally coming up with a product which we think meets the requirements of the new safety regulations completely.

Key Features

  • Developed from scratch to ensure a bespoke product which is fit for purpose
  • Class A1 product
  • Galvanised steel (ensuring extreme temperature tolerance)
  • Telescopically adjustable
  • Different headpieces available to ensure suitability for both decking and paving installation
  • Similar, circular base to our universal pedestals for satisfactory weight distribution

Class A1 Fire Rated Pedestals

Why Is This New Product Needed?

Building Regulations prohibit the use of combustible materials in external walls on “relevant buildings” over 18 metres above ground level. These regulations have been in force since December 2018.

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).

To view the full list of building regulations in England covering fire safety matters within and around buildings, please click here.

What Is The Impact?

These updated regulations mean that combustible materials are no longer permitted on the external walls of new buildings or material alterations to the buildings covered by the regulations.

The Regulations require that materials which form part of the external wall or specified attachment have to achieve the requirements of European Classification A2-s1, d0 or A1 (Classified in accordance with BS EN 13501-1:2007+A1:2009 entitled “Fire classification of construction products and building elements”). There are limited exceptions, such as door frames and doors, electrical installations, certain parts of roofs, window frames and glass.

Non-Combustible, Fully Adjustable, Class A1 Fire-Rated Pedestal

MetalPad with Click-deck head for decking

New legislation was introduced on 21st December 2018 which specifically relates to the fire requirements of external balconies in England and Wales.

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) under the criteria of EN 13501-1

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

Introducing The ‘MetalPad’

Why Are Fire-Rated Pedestals So Important?

Fire rated pedestals for decking

Previously unknown in exterior applications, non-combustible pedestals and pads are now essential products to ensure compliance with fire regulations affecting the construction industry which have become significantly more stringent.

At Wallbarn, we have acted pro-actively to the changes in fire safety regulations to produce a range of products which are fully compliant to the new regime for high rise balconies and terraces.

Based upon our ASP and Universal pedestal design to help distribute weight effectively, we have developed a steel adjustable pedestal for paving and decking which is a Class A1 product.

Fire rated pedestals for decking

Why Are These Products Necessary?

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, particularly on balconies and terraces at heights of over 18 metres.

The MetalPad Class A1 fire-rated pedestals have been designed to meet the requirements of every terrace and balcony specification which requires the installation of fire-rated products.

Our Class A1 fire-rated pedestals have been created to offer a fully adjustable galvanised-steel solution offering longevity, durability and strength.
