MIG-ESP® – Active Coating

What is MIG-ESP® Coating

  • energy efficient and anti-microbial coating system
  • not a conventional paint, but an active interior, or exterior coating, a multilayer, breathable, heat reflective dehumidification system
  • non-flammable

MIG-ESP® is a revolutionary active coating system that provides significant additional values and benefits by delivering improvement in energy efficiency, indoor environmental quality for healthier, more durable buildings.

MIG-ESP® is based on the robust DHMb® (Double Hybrid Membrane) Lining technology that reflects IR and UV rays as well as regulates humidity of a building thanks to its elastomeric, micro-porous structure. Either used as a finish coat in concert with traditional forms of insulation underneath,  or together with MIG-ESP® thermal insulating plaster as a stand-alone system, the coating can support or replace traditional insulation by upgrading the thermal insulation performance of both old and new properties where it is essential to avoid problems with mould and dampness without making structural change. Its moisture management properties enable the elimination of unpleasant odours and harmful pollutants from indoor air, making it fresh and healthy to breathe. Moreover, the coating system is enhanced with a natural antimicrobial element, which provides hygienic protection for wall surfaces as an effective way to minimise the risk of itransmission of microbes.

    • Why traditional insulation has significant limitations Insulation acts as a defensive barrier that regulates the way heat travels in and out of buildings. Traditional insulation systems are designed to slow down the transfer rate of heat energy. Heat energy will be absorbed and then, with a delay, released. In other words, standard insulation does not stop heat transfer from happening, it just creates a kind of buffer zone in between the indoor and outdoor environments. Sooner or later, heat gain or heat loss will occur no matter how efficient the insulation claims to be. Another important argument that speaks against traditional insulation is, it works only to the extent that humidity is left out of consideration. As soon as there is humidity the insulation performance will be compromised. For example, in mineral wool, just 4% of moisture will reduce the effectiveness of insulation by 50%. Worse still, sudden rises and drops in temperature will turn the moisture trapped inside the insulation into water, resulting in condensation and mould problems.
    • Why heat reflective paint has limited effect Heat reflective paint contains glass or ceramic spheres to reflect sunlight, minimising heat absorbed. While heat reflective coating for e.g. external roof surfaces has been around for a while and is effective for reducing heat from direct sunlight, it has significant limits. Firstly, it reflects only a very limited range of the solar radiation spectrum – mostly direct energy from the sun, which means a wide range of infrared radiation is not reflected. Secondly, although it’s true that white paints alone have a high solar reflectivity, they’re only reflective under ideal circumstance: humidity is not taken into consideration. As with normal paints, as soon as moisture sets in, the insulation effort collapses. Thirdly, heat reflective paint doesn’t block or prevent the heat from leaving the building.
    • How DHMb® lining system works Contrary to static insulation, such as Styrofoam and mineral (glass) fibre, DHMb® is a dynamic system that manages IR and UV radiation as well as moisture. Water vapour in the air has a high specific heat capacity, hence reduction of moisture reduces heat transfer (loss or gain) dramatically. By reflecting heat (radiation) and repelling heat energy contained in water vapour, the MIG technology avoids absorption and hence the transfer (conduction) of heat through walls and roofs. As a result, condensation and heat storage can be minimised. In turn, reduction of condensation (water) improves the heat conservation dramatically. Reflective surfaces are most effective externally only, whereas DHMb® technology is effective both internally and externally with heat reflection of a broad spectrum of electro-magnetic waves. Thus, thermal energy can be retained inside the building. At the same time, moisture will be removed from the base material. Walls will be dry and indoor air quality improved. Dry surfaces are resistant to mould and bacteria, leading to a healthier indoor climate.

    MIG DHMb® Lining System Active exterior and interior coating

    MIG-ESP System Exterior

    The DHMb® Lining System is a multi-layer wall coating system with special properties that reduce energy costs in buildings in an environmentally friendly and sustainable way.

    The application of the complete system can replace and/or significantly supplement the cladding of a building with the environmentally damaging and cost-intensive thermal composite system (insulation).

    The MIG-ESP® products can also be used individually to improve existing wall structures and enhance buildings inside and outside.
