Thermal Insulation
Our latest manufacturing line is that of Insulation ECO PU Boards. These are made of polyurethane foam which is the optimum material when it comes to insualtion and having a conductivity of 0.025W/m.K.
Building insulation is a requirement in every EU country as implied by the EU parlament as Minium Requirements On The Energy Performance Of Building Directive of 2002.

Polyurethane is closed-cell foam that contains a low-conductivity gas in the cells (usually one of the HCFC or CFC gases.) The high thermal resistance of the gas give this foam an R-value of between R-7 and R-8 per 25mm.

Both types are available as a liquid spray, poured foam and also as rigid boards. They can also be made into laminated panels with a variety of finishes. Foamed-in-place applications are usually cheaper than installing foam boards and perform better since the foam moulds itself to all of the surfaces perfectly.

Over time, the R-value of the foam drops as some of the gas escapes and air replaces it. This phenomenon is known as thermal drift. When manufactured, the initial R-value is roughly R-9 per 25mm. Experimental data on this type of foam indicates that most thermal drift occurs within the first two years after manufacture and slowly decreases until it stabilizes at about R-7 per 25mm. It then remains unchanged unless the foam is damaged.

Foil and plastic facings on these foam panels help to slow the escape of gas from the cell structure. Testing suggests that the stabilized R-value of rigid foam with metal foil facings remains unchanged after 10 years. The reflective foil, if installed correctly, can also act as a radiant barrier (another type of insulation) that adds about R-2 to the insulating assembly. Panels with foil facings have stabilized R-values of 7.1 to 8.7 per 25mm.

Common Applications of Foam Insulation:
Spray foam and foam boards can be used to insulate almost anything, including: roofs, walls, foundations, entry and overhead garage doors, pipes and tanks, under basement slabs, or over a slab-on-grade floor. Foam insulation sprayed or placed in wall and floor cavities both insulates and offers some degree of soundproofing.

Protect all types of foam insulation from direct sunlight. Over time, the sun's ultraviolet rays can damage them. For roofs this is generally done by applying a coating such as tar, acrylic, silicone or rubberized paint. You can also cover the foam with a rubber or plastic membrane or a layer of asphalt and roofing felt. Make certain you are using compatible products. The solvents in some coatings dissolve certain plastics.

There are several ways to incorporate foam insulation in concrete or masonry walls: pouring loose foam beads into masonry blocks; injecting/ pouring liquid foam into the hollow block cores; manufacturing concrete blocks to accommodate rigid foam inserts; as lightweight concrete blocks that have polystyrene beads in the concrete mixture; and as rigid foam insulation inside a cast-in-place wall. There are also interlocking rigid foam panels and blocks that serve as permanent forms for concrete walls and foundations. These are commonly known as Insulating Concrete Forms (ICF's.)

Potential Moisture Problems:
In cold weather, warm inside air containing water vapour can get past the wall finish and insulation and condense inside the colder wall cavity. In hot-humid climates the same thing can happen, just in the reverse direction, humid outdoor air in the summer can condense inside cool/air conditioned wall cavities. If enough of this happens, and the water cannot escape, wood rot, mould, and other moisture-related problems are likely to occur. For this reason, building codes often require installing a vapour diffusion retarded on the warmest side of the wall cavity.

Foam board insulation is commonly placed between the exterior finish (i.e., siding, brick) and the studs of exterior walls. To prevent air infiltration, you should place rigid insulation boards tightly together and seal the seams with tape or caulk. However, this practice may worry some builders in cold climates since the foam board may act as a second vapour diffusion retarded. Studies have shown, however, that condensation rarely occurs in these areas unless something else is seriously wrong with the wall assembly (i.e., massive uncontrolled air leakage into the walls from the house.) If the assembly is constructed correctly, the inside surface of the foam board stays warm enough to keep water vapour in its gaseous state long enough for it to escape.

Polyester Insulation Batts

Polyester batts are resilient and compressible insulation manufactured to a wide range of R-Values & S-Product. They are user friendly, inherently moisture resistant and will not break down.

Polyester batts are non-allergenic, odourless, require no protective clothing to install and are easy to install.

The product is 100% polyester, long chain synthetic polymer fibres and the chemical entity is composed of carbon-hydrogen oxygen. Thermal insulation polyester batts come in different widths to suit standard construction.

By incorporating thermal insulation in the building structure, the occupants experience increased comfort and at the same time the amount of energy used is minimised. Polyester batts are designed to keep heat within a building in winter and slowing the flow of heat into the building in summer. Insulation can cut the cost of heating and cooling by over 40%. Insulating the ceiling of a house has the potential to saving 20-30% on heating and cooling bills. Adding R1.5 insulation to external walls gives an additional 10-20% saving. Air conditioning system capital and running costs can be minimised by using adequate insulation in the building envelope.

Polyester is an excellent sound absorber and can assist in reducing noise transmission through walls, ceilings and floors, making the home or work environment quieter; ideal product for cinemas, garages, tunnels etc.

Maximum Service Temperature
Maximum service temperature is 120ºC. The product is intended for use at temperatures normally prevailing in building structures, the melting point of polyester is 250ºC.

Corrosion Resistance
Polyester batts are not considered to be corrosive; they have a pH level of 7.5-8.0.

Fire Resistance
Polyester Batts comply with the building code of BS and is a self extinguishing Product.

When tested in accordance with AS 1530: Part 3 – 1989 equivalent standards BS 476-32:1989 for Fire tests on building materials and structures. The polyester batts have the following Early Fire Hazard Indices:

Ignitability 0
Spread Flame 0
Heat Evolved 0
Smoke Developed 3

Moisture Resistance
Polyester batts are not affected by moisture. If the batts become wet, full thermal performance is retained after batts are dry.

Exposure to an atmosphere of 50ºC at 90% relative humidity for 96 hours results is moisture absorption of less than 0.2% by volume.
