Dynamic External JDE [EWI Rail/Panel]

Dynamic External Wall (JDE) products are designed for retrofit or new build external wall application as a solid wall insulation system that couples the ventilation system to the insulation. The Dynamic EWI system can produce U-values of circa 0.15W/m².K using only 100mm EPS insulation.

Two systems have been developed:

• A Panelised System where the air channels are encompassed in the panel – the panel is fixed to the wall as per convention
• A Rail System where the air channel is formed between the existing wall and the insulation.

The combination of ventilation and insulation results in the following benefits over a conventional solid wall insulation:

• 0.15W/m2.K U-value in 100mm of insulationReduced thermal bridging
• 20% increase CO2 savings
• Thinner form factor
• Less intrusion into internal / external areas
• Greater subsidy level from CERT/CESP schemes
• 10% reduction in net cost for Housing Providers
• 27% reduction in Household Utility Bills
• Improved indoor air quality
• Payback time reduced from 8.5 to 6 years

Dynamic External Insulation products are OFGEM recognised for current government utility subsidy schemes such as CERT and CESP.

Dynamic External Wall (JDE): Product Specification

JDE is manufactured by Jablite from Graphite Impregnated Expanded Polystyrene (EPS) for standard 50-100mm systems:

EPS is recognised for its excellent energy efficiency and low environmental impact with a zero ODP (Ozone Depletion Potential) and low GWP (Global Warming Potential).
