Green Roof

A green roof can be an oasis in the city landscape.

As land continues to be replaced with impervious surfaces due to population growth and urbanisation, the necessity to recover green space is becoming increasingly critical to maintain environmental quality.  Installing green roofs is one option that can reduce the negative impact of development while providing numerous environmental, economic, and social benefits.  They can improve stormwater management by reducing runoff and improving water quality, conserve energy, mitigate the urban heat island, increase longevity of roofing membranes, reduce noise and air pollution, sequester carbon, increase urban biodiversity by providing habitat for wildlife, provide space for urban agriculture, provide a more aesthetically pleasing and healthy environment to work and live.

green roof is a roof surface, flat or pitched, that is planted partially or completely with vegetation and a growing medium over a waterproof membrane. They may be ‘extensive’ and have a thin growing medium (up to 200mm deep) with ‘ground cover’ vegetation, or ‘intensive’ and have soil over 200mm deep supporting vegetation up to the size of trees.

DCT GA 300

Details

DCT GA 300 extruded polystyrene (XPS) general application board provides excellent performance in roofs, walls and floors in both commercial and residential applications. The boards are rot proof, stable, durable and will have a life equivalent to that of the structure in which they are incorporated.

DCT GA 300 offers top performance with regards to thermal insulation, maintaining this characteristic under extreme conditions of compression, humidity and temperature. The exceptional compressive strength enables it to easily resist several tons/m² downward pressure.

The closed cell structure of DCT GA 300 XPS foam makes water absorption almost non-existent and provides a high resistance to vapour transmission. The specially designed tongue and grooved edge profile facilitates rapid and robust installation.

Applications

  • Exterior walls over studs or non-insulating sheathing like OSB or plywood interior walls – concrete blocks
  • Ceilings – cathedral, vaulted or flat ceilings, finished attic
  • Exterior foundation walls
  • Interior foundation walls
  • Crawl space

Styrofoam RTM-X

Details

Styrofoam™ RTM-X extruded polystyrene (XPS) thermal insulation distributed by DCTech, is recommended as a core material in sandwich panels for the walls, floors, roofs and doors in refrigerated trucks and containers.

With long term proven performance and creep data, Styrofoam™ RTM-X XPS thermal insulation is an ideal engineered product that designers may confidently specify in today’s increasingly highly loaded floor designs. For sandwich panel cores, the lightweight, close tolerance, dust-free surface allows for excellent bonding to a wide variety of sheet materials.

Styrofoam™ RTM-X XPS rigid insulation has been specifically designed to withstand severe dynamic loads and stresses which may eventually lead to fatigue and failure. It is specially designed to resist such force and in tests has been shown to perform extremely well under dynamic load cycling.

Styrofoam™ RTM-X XPS insulation is manufactured through a continuous extrusion process, and as with all Styrofoam insulation products possess a rigid closed cell structure with unique properties such as low thermal conductivity, high resistance to water penetration and high compressive strength.

Styrofoam™ RTM-X XPS thermal insulation is produced in a range of thicknesses and is grooved on both facers. Styrofoam™ XPS insulation products are not biodegradable in the environment, and do not present an environmental hazard in the water/soil compartment. When correctly installed, Styrofoam™ XPS insulation products have a service life comparable with the remainder of the building or structure. Styrofoam™ XPS boards can be reused, even after having been installed for decades.

Applications

  • Core material in sandwich panels for the walls, floors, roofs and doors in refrigerated trucks and containers

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.

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.

Features

  • High vapour permeability
  • Water resistance up to 2.5m head of water
  • UV stable for up to 2 months exposure in Australia and New Zealand
  • Resistance to the effects of lime water, sodium chloride solution and sulphurous acid in concentrations required by EN 1847
  • Strong, yet lightweight for ease of application
  • Resistant to mould
  • Available in 3m wide rolls to reduce overlaps

Applications

  • As a vapour permeable separating and water control layer for use in Inverted Roof Membrane Assembly (IRMA) Systems
