Jablite Dynamic Cavity
DELIVERS SUPERIOR U-VALUES IN A TRADITIONAL BUILD
Jablite Dynamic Cavity wall insulation is a unique innovation developed by Jablite in partnership with Energyflo, an offshoot of Aberdeen University.
Key Features of Jablite Dynamic Cavity Wall Insulation
- Designed for use with all forms of masonry cavity wall construction
- Easy to install
- Works with a mechanical ventilation system
- Improved air quality and reduced condensation risk
- Achieves a Code 4 rating with a 100mm cavity in a 300mm wall
- Can be used in combination with Jabfill Premium to insulate a whole house
- Contains flame retardant additive
- Listed in SAP Appendix Q
- Manufactured from EPS (expanded polystyrene)
- EPS has an A+ rating in the BRE Green Guide to Specification
- Approved and tested by the NPL and BRE
- BBA certificate 96/3215 is pending
Jablite Dynamic Cavity uses Energyflo technology to turn a simple wall into a sophisticated heat exchanger. Heat, which would otherwise be lost through the wall of the building, is harvested and utilised to warm cold air being drawn into the building.
With Jablite Dynamic Cavity wall insulation it is possible to achieve outstanding U-values, even Passivhaus status without changing from a traditional building style.

Jablite Jabfill and Jablite Dynamic Cavity are used in the cavity of traditional brick and block wall constructions. The insulation can be placed wholly within the cavity or additional layers can be placed on the internal or external face of the wall.
Taylor Wimpey choseJablite’s innovative Dynamic Cavity insulation to trial in nine new homes in Saffron Walden, Essex.
“This trial is line with our policy of building all our homes to meet the Code for Sustainable Homes Level 3,” explains Andy Harrington, Technical Director for Taylor Wimpey East London.
Taylor Wimpey is known for its commitment to a good environmental performance: “We are constantly seeking to improve the sustainability of the homes that we build in the UK,” adds Andy.
“High performance insulation is a good way to achieve that, so naturally we were interested to trial Jablite’s new insulation to see how it performs. Energy efficiency is very important to home owners, not just because of rising costs, but there is a genuine appetite for homes that are built for sustainable living.”
Jablite’s Dynamic Cavity insulation promises to deliver a U-value of 0.17W/m²K in a 100mm cavity. This is substantially better than standard, premium blown bead in a 100mm cavity, which offers a U-value of 0.25W/m²K. An additional benefit that comes with Jablite Dynamic Insulation is improved air quality because of the inbuilt ventilation system
“So far we are very pleased with the ease of installation and the fact that if offers an option in our standard 100mm cavity new builds. A well-insulated house is a comfortable, snug home and that is important in our climate,” adds Andy Harrington.
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.
