Dynamic Cavity JDP [Masonry Partial-Fill]

Dynamic Insulation products are available for different construction types and panel thicknesses. 

Dynamic Cavity Partial-Fill (JDP-XSCW) is designed for conventional masonry cavity construction with partial-fill insulation.

JDP is manufactured by Jablite from Graphite Impregnated Expanded Polystyrene (EPS) and available for standard 75 / 100mm cavities:

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).

Dynamic Cavity Partial-Fill (JDP): Product Specification

Dynamic Insulation products for partial fill cavity-wall insulation in traditional new build masonry external walls are designed for installation during construction. The insulation panels are fully interlocking and dry fixed to the face of the inner leaf of masonry as per normal insulation.  

The external faces (front and back) of the panels also incorporate vertical grooves that act as guidelines for cutting the panels. The front face also incorporates tapered flutes to provide a drainage plane and shed water away from the internal leaf. In accordance with BS 5628-3:2005 the panels are designed to prevent water reaching the inner leaf. The flute detail also ensures that water penetrating the outer leaf of the wall will drain down the cavity face of the outer leaf, therefore satisfying the respective national regulations for buildings.

Panels can be trimmed along the vertical grooves on the face of the panel using normal rigid insulation working tools. Once installed the Dynamic Insulation system acts as an air supply to all types of mechanical ventilation systems.

Dynamic Insulation partial fill cavity-wall insulation panels are available in 100, 125 and 150mm thicknesses in two types of insulation material; 

• Standard Expanded Polystyrene; ‘K’ value of 0.038W/m.K.
• Carbon enriched Premium Expanded Polystyrene; ‘K’ value of 0.030W/m.K.

The Dynamic Insulation partial fill cavity-wall insulation system is made up of 3 panel types:

1. BC Panels (Base Channel Panel) is specified to permit air inlet to the channel i.e. at the bottom of the wall and (if required) above the ground storey air intake point.
2. H Panels (Half Height Panel) is 225mm in height and is specified to ensure that the dynamic insulation layer finishes one block below the air intake point specified on the drawing.
3. CC Panels (Collector Channel) is specified at the air intake point.  Specification of air intake point is defined by the choice of ventilation system.
