Jumbolene Roof Insulation

Jumbolene Roof Insulation is a 3 in 1 reflective foil insulation solution, combining the benefits of reflective insulation, a radiant barrier and a moisture barrier. It is recommended for residential, commercial and industrial roof systems.
Jumbolene Roof Insulation is 100% closed cell polyethylene foam, laminated with aluminium reflective foil. Polyethylene foam has a very low rate of conduction, effectively reducing the amount of heat transmission into the building.
Why choose Jumbolene?

  • Effective thermal and acoustic insulation
  • Will not absorb moisture
  • Light and easy to install
  • Non toxic
  • Environmentally friendly
  • Seals around nails (no leaks)
  • Keeps its thickness over time (its structure does not collapse)
  • Reduces Carbon emissions
  • Locally manufactured

Thermal Insulation: Jumbolene has a low thermal conductivity of 0.0293 W/m.K, which is not affected by humidity or condensation. It reflects 97.1 % of radiant heat and does not lose its thermal performance over time. Reflective insulation is most effective when airspace exists between the insulation and the adjacent material. Minimum recommended air space is 25mm for residential roofs and 50mm for commercial roofs.

Acoustic Insulation:
Jumbolene is an effective barrier against impact noise from rain. Rain noise is a potentially important noise source which must be considered at an early point in the roof design in order to minimize disturbance within the building.
Durability: Jumbolene is guaranteed during the lifespan of a building. It is resistant to dust, mould, mildew and bacteria and does not provide nesting to insects, birds or rodents. It is chemically inert and will not react with acids, alkalis or metals.
Water and moisture resistance: It has a low moisture permeability index of 0.05% g/m², in 24hrs and water absorption index of less than 2% in 28 days. As a roof underlay it does not leak as it seals around nails.


Jumbolene® Duct Wrap

Jumbolene® Duct Wrap ensures greater energy efficiency, reduces unwanted noise and improves the performance of air conditioning systems.Jumbolene® DuctWrap is effective thermal insulation made from closed cell polyethylene foam fused with reinforced aluminium foil facing. Its closed cell structure ensures effective condensation prevention while offering excellent insulation against heat loss or heat gain. Jumbolene® DuctWrap ensures low energy consumption and excellent vibration dampening.

Uninsulated or poorly insulated duct can lose through conduction 10%–30% of the energy used to heat and cool a building. The heating and cooling equipment then has to compensate for the heat loss and gain by conditioning additional air. This added conditioning raises energy consumption and consequently, the energy bills.

Jumbolene® is lightweight, water-resistant, energy saving and easy to install. It is applicable in insulating all shapes of duct lines and waste systems. It can be installed in commercial, industrial and residential projects.


  • Excellent thermal insulation
  • Prevents condensation
  • Excellent vibration dampening-reduces noise
  • Fire retardant
  • Excellent chemical resistance
  • Resistant to bacterial and fungal growth
  • Light weight
  • Easy to install
  • Non toxic
  • Free from synthetic fibres
  • Easy to cut and fit


Jumbolene Flat Roof And Wall Insulation

Jumbolene wall and roof insulation is a semi-rigid board, made of low density, closed cell polyethylene foam. It is ideal as wall insulation and as a flat roof under or over membrane roof insulation. It has a low thermal conductivity of 0.0293 W/M.K.  It does not break like polystyrene foam products and can take the weight of ballast or pavers if the roof area is also subject to pedestrian traffic. The product can be easily cut and shaped to suit a variety of geometries.

Jumbolene = Reflective insulation + Radiant barrier + Vapour barrier.

Product Dimension (Standard)

  • Thickness: 25mm & 50mm *Both thicknesses come with either an aluminium reflective foil face or plain finish
  • Width: 1m
  •  Length: 2m

Why Jumbolene?

  • Excellent thermal resistance. At 50mm, Jumbolene insulation boards have an R value of 1.71
  • Mould resistance. Do not allow the growth of fungus.
  • Completely free from all synthetic mineral fibres (SMF's) and therefore no special clothing including respirators is required.
  • User friendly and completely safe to handle.
  • While Jumbolene is fire retarded, in the event of ignition gases released are non-toxic: i.e. NO carbon monoxide or hydrogen cyanide.
  • Will take pedestrian traffic if installed under pavers.
  • Where access is required for services, the product is easily cut with a sharp knife and does not tear, rip or splinter.
  • Jumbolene is not rigid or brittle and therefore will not crack or snap when being handled or transported.
  • Jumbolene is economical, as there is low wastage due to the variety of sizes available, and is ideal where tight roof levels exist as there is no necessity to alter roof levels.
  • A range of thicknesses available to meet required 'R' values.
  • Fully recyclable.
  • Offers low water absorption index of 0.02 mg/cm2 and moisture permeability index of 0.05% g/m2/day.
  • Provides Acoustic noise Insulation.

Suggested Application

Jumbolene insulation shall be held in position using weld pins and press washers to firmly secure the insulation to the soffit of the roof or podium slab.

  • A minimum of five pins per Jumbolene insulation shall be used, preferably two at each end and one in the centre.
  • All insulation shall be installed with the edges and ends tightly butted together.
  • Where necessary, the insulation may be easily cut using a sharp knife.
