ProctorGeo IRMA
Details
ProctorGeo IRMA is designed for use as a separating layer in ballasted or paved Inverted Roof Membrane Assembly (IRMA) flat roofs. ProctorGeo IRMA acts as a filter layer preventing fines and other debris from passing through, and also as a water flow reducing layer minimising cold rainwater flowing between the insulation and the roof waterproofing thus reducing the consequent rainwater cooling effect.
Rainwater that penetrates IRMA roof systems reaching the waterproof layer can impact on the thermal performance of the construction. To take account of this loss in thermal performance, the initial R-value of the roof should be corrected by subtracting a rainwater correction factor (determined using the method described in BS EN ISO 6946:2007) dependent on local rainfall and the proportion of rainwater reaching the waterproof layer under the insulation.
This can be substantially reduced by incorporating ProctorGeo IRMA as a water-flow reducing layer directly above the insulation, to drain rainwater off the roof before it reaches the waterproof layer.
ProctorGeo IRMA is impermeable to liquid water and substitutes conventional fleece filter fabrics that do not perform as an effective water draining separation layer.

ProctorGeo Vap 120
Details
ProctorGeo Vap120 is a light duty vapour retarder and convection barrier. The high air and water vapour resistance of the two layer polyolefin non-woven membrane resists the flow of vapour by both diffusion and air movement through wall, ceiling and floor assemblies thus helping protect the building fabric and insulation from condensation and related problems such as mould, timber rot, corrosion and loss of thermal resistance.
When installed as a continuous layer, ProctorGeo Vap120 will help form an air tight layer reducing the loss of heated air or cooled air from the building thus improving the energy efficiency of the building enclosure.
Vapour retarder should be ProctorGeo Vap120 vapour retardant membrane, tested to AS/NZS 4200,1:1994 standards, secured in accordance with product user guide.

ProctorPassive SmartVap 100
Air barrier with variable vapour diffusion resistance
Product Description
ProctorPassive SmartVap 100 (SmartVap) is a two layer AS4200.1 compliant light duty air barrier and variable vapour diffusion resistance retarder.
Application
When installed as a continuous layer, SmartVap will form an air tight layer, improving the efficacy of ventilation systems and thermal efficiency of the building enclosure. The effective management of air and vapour passage through wall, ceiling and floor assemblies can help protect the building fabric and insulation from condensation and related problems such as mould, timber rot, corrosion and loss of thermal resistance.
SmartVap should not be used on the exterior side of insulation in cold and temperate climates as an alternative to a vapour permeable sarking, where there is a risk that condensation will form on the interior face of the retarder.
Variable vapour diffusion resistance
The functional layer of SmartVap is a polyamide film. Such films passively adjust vapour diffusion resistance depending on the humidity where located. The polyamide absorbs water vapour from the air, opening the molecular pores thus adjusting vapour diffusion resistance according to ambient humidity conditions.
SmartVap is not “smart” enough to tell what season it is, and it would be simplistic to claim vapour tight in winter and vapour open in summer. The vapour resistance of SmartVap is not seasonal, but is influenced by the relative humidity on both sides of the membrane where it is located, whatever the season.
When the ambient humidity is low the diffusion resistance is higher. When the ambient humidity is high, the diffusion resistance is lower. This functionality can assist the building fabric to dry towards the interior when relative humidity is higher, and vapour pressure is lower on the interior side of the membrane.
Durability
Although ProctorPassive SmartVap can be used as temporary protection during construction, it can not be used as a primary waterproofing membrane. The product may be damaged by careless handling, high winds or vandalism, and should not be left uncovered for longer than is absolutely necessary. Any damaged areas should be replaced before completion.
Ensure that ProctorPassive SmartVap is covered as soon as possible, and not left exposed to UV for longer than 4 weeks. ProctorPassive SmartVap is not to be used in installations where it could be exposed to long term UV radiation.

ProctorGeo D-Rain DC8 Plus
Details
ProctorGeo D-Rain DC8 Plus (GeoD-Rain DC8+) is a dimpled HDPE sheet that provides an effective drainage and membrane protection layer for use with foundation walls, flat roofing and underground structures. The integration of a 100gsm non-woven geotextile over the 3 dimensional dimpled layer prevents soil particles from blocking drainage.
The D-Rain DC8+ structure effectively captures and transports high volumes of water and resists the loads from earth and formwork. The compressive resistance 200kPa will be suitable for most common applications but where a higher compressive resistance is required, please contact us with your requirements. Products such as D-Rain DC10+ may be suitable.
D-Rain DC8 Plus is installed with the non-woven geotextile facing the backfill, soil or ballast.
