Central Roofing, Managing Director, Tony Davies, says:
“We like using Jablite Flat Roof Inverted because it is so easy to install. We are supplied with one board to the required thickness; the pieces can be slotted together like a jigsaw – they are lightweight and durable.
“Jablite collects off-cuts from the site and recycles them in the UK - we are ISO 14001 registered so that is important to us.
“We use Jablite Flat Roof Inverted on high calibre projects like hospitals and clinics where there are millions of pounds of equipment in the building and the building manager cannot afford to take any risks."
Membranes in traditional cold and warm roofs are exposed to the elements and are prone to expansion and contraction during the course of their lifespan. With age, these membranes can weaken and crack leading to leaks and replacement in relatively short periods of time
Jablite Flat Roof Inverted solves this problem by being a specially developed insulation that is laid over the membrane, thus insulating it from the worst of the weather, leading to greater longevity of the whole waterproofing system.
The London housing association, Genesis Housing Group, re-developed a former light industrial site to create six mixed-use, mixed-tenure buildings ranging between two and 43-storeys to provide a total of 704 homes
This high profile scheme is located at the principal entrance to the Olympic Park, at 150 High Street, Stratford. As well as homes, it provides an Extra Care Unit, affordable commercial and retail units, car and cycle parking, a children’s play space and a riverside walkway.
A CHP plant, biomass boilers, rainwater harvesting and green insulated roofs have all been incorporated into the scheme; together with considerable areas of water attenuation on the 1.3-hectare Thames-side site, they combine to create a sustainable project.
Jablite Flat Roof Inverted Insulation
The roofs were designed and specified by Radmat Building Product, Jake Watkins, explains why he chose Jablite Flat Roof Inverted insulation, “Energy efficiency is a key element in all our sustainability planning for the roofs we design.
“Jablite Flat Roof Inverted insulation was perfect for this project, because it is supplied in incremental thicknesses to provide any specified U-value and it works well with green roofs.”
Jablite Flat Roof Inverted insulation is manufactured from a modified EPS (expanded polystyrene) bead which makes it resistant to moisture and therefore suitable for use on inverted flat roofs.
It is designed to be easy to install – a decisive factor as Jake explains: “Importantly for a project of this size, Jablite Flat Roof Inverted insulation can be quickly and easily installed – it comes in lightweight, 1200mm x 1200mm overlapping sheets that are strong enough to be walked during the installation.
“Jablite is available in increments of 5mm from 100mm to 250mm and is supplied for single layer installation – this reduces the amount of waste material and eliminates the need to glue layers together – on or off site.
“For this project the insulation boards were 200mm to achieve our required U-value of 0.16w/m2k,” concludes Jake.
Jablite provided a site collection recycling service to collect offcuts and recycle them back into insulation board.
SUSTAINABILITY AND JABLITE INSULATION PRODUCTS
Jablite Insulation and the Code for Sustainable Homes
The Code for Sustainable Homes (the Code) is the national standard for the sustainable design and construction of new homes. The Code aims to reduce our carbon emissions and create homes that are more sustainable. It applies in England, Wales and Northern Ireland.
A copy of the Code can be found here.
CODE FOR SUSTAINABLE HOMES, CATEGORY 3: MATERIALS
Mat 01: Environmental Impact of Materials
Jablite insulation products are made from EPS (expanded polystyrene) which has an A+ rating in the BRE Green Guide*.
*The BRE Green Guide to Specification provides you with easy-to-use guidance on how to make the best environmental choices when selecting construction materials and components.
Environmental rankings: A+ represents the best environmental performance and E the worst environmental impact.
CODE FOR SUSTAINABLE HOMES, CATEGORY 6: POLLUTION
Jablite Insulation has a Global Warming Potential (GWP) of less than 5 and an Ozone Depletion Potential (ODP) of zero.
The blowing agent used during manufacture is pentane which has zero ODP and a GWP of less than 5.
BREEAM (Building Research Establishment Environmental Assessment Method) sets the standard for best practice in sustainable design and in the measurement of a building's environmental performance. BREEAM enables developers, designers and building managers to demonstrate the environmental credentials of their buildings to clients, planners and other parties,

BREEAM, MATERIAL 04 INSULATION
In this category, the specified aim of BREEAM is to “recognise and encourage the use of thermal insulation which has a low embodied environmental impact relative to its thermal properties and has been responsibly sourced.”
It is a pre-requisite of BREEAM that any new insulation specified for use within the following building elements must be assessed:
1. External walls
2. Ground floor
Jablite insulation products are made from EPS which has been given an A+ rating by the BRE.
The calculation of embodied impact relative to thermal performance is a function of the material volume (for each build), its BRE Green Guide Rating and its thermal conductivity.
The thermal conductivity of our products is available on both the product packaging and on relevant product technical datasheets which can be found on this website.
Jablite insulation products are manufactured in factories which are ISO 14001 certified and Jablite purchases raw material from suppliers who are ISO 14001 certified.

Jablite Insulation and the Environment
Jablite insulation products are 100% recyclable. We collect waste from building projects and recycle it.
Our manufacturing process
All Jablite insulation products are manufactured at sites with ISO 14001 certification.
Steam is the main ingredient used in the manufacture of Jablite insulation. The water consumption is low because the water is clean and can be re-used many times in the process.
No solid waste is generated during the manufacturing; any broken or faulty parts that do not pass our stringent quality control standards can be broken up and re-introduced into the process.
Jablite insulation products do not contain and are not manufactured using any substances which are controlled under Montreal or Kyoto Protocols.
Efficient use of natural resources
Jablite insulation products are 98% air and therefore extremely resource efficient. The lightweight nature of Jablite insulation means that less fuel is used when transporting from factory to building site.
Jablite insulation products are made from expanded polystyrene (EPS), a plastic that is obtained from oil. In Europe, the percentage of oil used in manufacturing EPS is 0.1%.
The monomer styrene has been manufactured for more than 70 years and is used in a wide range of products.
Styrene exists naturally and can be found in many foodstuffs including strawberries, beans, nuts, beer, wine, coffee beans and cinnamon.
Pentane, a non-CFC expansion agent is used to expand polystyrene granules into the cellular structure that makes the production of EPS possible.
Pentane is a slightly volatile liquid in the same chemical family as methane, ethane, propane and butane and is continually being formed in natural processes in the digestive systems of animals and the decomposition of vegetables. It is not considered a substance harmful to health by European health authorities.
Pentane does not contain chlorine and therefore does not harm the ozone layer.
No CFC’s (chloroflourocarbons) or HCFC’s (hydrochloro-fluorocarbons) are used in the manufacture of EPS.
