Key Facts

    • A rigid and hydroscopic insulation board (9mm) laminated to the remarkable Thermablok Aerogel hydrophobic insulation membrane (10mm) with an impressive R-value of 0.82 (m²K/W). Available in multiple thicknesses for increasing R-values.
    • A fully breathable system that ensures a healthy, durable working building with a natural ability to absorb, control and release moisture.
    • Thermablok Aerogel does not rely on a vacuum or heavy molecular gases to insulate.
    • Thermablok Aerogel is hydrophobic and is therefore not affected by moisture or age and is a hostile environment, offering no bacterial platform for mould growth.
    • Unlike paper faced/wood based products, Magnesium Board also provides a hostile environment, offering no bacterial platform for mould growth.
    • Direct,  mechanical fix to the existing masonry substrate without the need for any framing system or ventilation cavity, which means even further space saving.
    • Also available is the advanced, unique and specially manufactured hydrolic lime plaster / board priming system to offer the most vapour open, 3mm to 4mm hydroscopic buffer finish available today.

Thermablok Aerogel Magnesium Wall and Ceiling Insulation Board

Thermablok Aerogel ThermaSlim IWI Board is a unique insulation board system that is remarkably thin, offering important savings on Gross Internal Areas (GIA) and is fully breathable, semi breathable or vapour controlled as required.

Installed as internal wall insulation (IWI) but also window reveals, party wall returns, ceilings, roof lines and in-between exposed timbers where reduced tolerances are critical.

Consisting of a hydroscopic 9mm magnesium oxide board laminated to Thermablok Aerogel, it is the thinnest and most thermally efficient panel available offering ease of installation with a single process, without need for a ventilation cavity and a perfect hydroscopic buffer carrier board on which to apply finish plaster. Moisture will be absorbed by the hydroscopic board and either held until point of ventilation or be allowed to pass as vapour through the Aerogel Insulation to be released through the breathable assembly.

Thermablok Aerogel ThermaSlim IWI Board is ideally suited where space is at a premium and loss of living area would impact upon occupancy, comfort standards, property/rental values and required Health & Safety regulations.

Thermablok Aerogel ThermaSlim IWI Board is available in a range of thicknesses for increasing R Values, giving architects and designers the freedom to design to maximum thermal standards whilst maintaining optimum internal dimensions. These systems are also available with or without a Vapour Control Layer (VCL) or Intello Layer depending on the desired vapour permeability and resistivity.

Thermablok Aerogel ThermaSlim is also available in a specially engineered rigid, layered and staggered composite board system for elimination of thermal bridging in floors and increases assembly R value ratings.
