Insulated Systems

Thermal insulation mortar for:

• Concrete roof decks,
• Underground floor slabs,
• Basement walls,
• Swimming pools,
• Lightweight filler for voids,
• Levelling of floor slabs,
• Cavity fill for steel frame construction,

• Easy to mix, place and finish,
• Cost effective,
• Homogenous bead distribution gives good workability and predictable performance,
• Good workability enables mixed material to be pumped 100 m horizontally and 30 m vertically,
• No loss of workability, even when pumped long distances,
• Mix design variable to produce densities from 200 to 1 000 kg/m3,
• Compatible with most finishing products and adhesives,

The application is applied onsite Politerm Blu is a pre-manufactured product which consists of expanded polystyrene (EPS) beads that are pre -treated with a chemical additive. This chemical treatment allows the effective mixing of the beads with water and cement in order to produce a mortar which is laid to falls as a thermal insulating roof screed. Politerm beads mix easily with cement and water, without floating and separation.

The material must be mechanically mixed in either a conventional concrete / mortar drum mixer, concrete truck mixer or purpose made Politerm PM1000 mixer/pump. The mixing action should be slow in order to achieve a good blending of the ingredients rather than a fast and harsh crushing together action, as this destroys the slight foaming action released by the chemical additive.

When applying the above mix to a concrete roof slab the concrete should first be saturated with clean water and not allowed to dry out prior to the application of the Politerm screed. Ponding of water should not be allowed. The Politerm screed mix should be “laid to falls” to rainwater outlets at a minimum thickness of 50mm. The maximum thickness will be determined by the distance of the fall.

The POLITERMBLU is applied to falls on a flat roof structure, then floated with sand cement screed, and waterproofed with torch – on.

Vermiculite is a naturally-occurring mineral composed of shiny flakes, resembling mica. When heated to a high temperature, flakes of vermiculite expand as much as 8-30 times their original size. The expanded vermiculite is a light-weight, fire -resistant, and odorless material and has been used in numerous products, including insulation for attics and walls.

Sizes of vermiculite products range from very fine particles to large (coarse) pieces nearly an inch long. The vermiculite is mixed with cement and water and applied to falls on a flat roof structure, then floated with sand cement screed, and waterproofed with torch- on.

• Tin roofs,

• Insulation,
• Sound proof,

This application is a three part system installed as follows:

• A layer of polystyrene sheeting is applied over the existing tin roof structure – the thickness of the sheeting will determine the amount of insulation and sound proofing required,
• In addition, a layer of Masonite or Shutter board is applied over the polystyrene sheeting and then fastened to the roof structure,
• Waterproofing torch-on is the applied over the top of the board creating a water tight seal.
