Underfloor insulation from Air-Cell doubles as moisture management solution


Underfloor insulation breakthrough doubles as moisture management solution. With energy efficiency and sustainable living on everyone's lips, extra efforts are being made to insulate roofs and walls. But what about floors? Up to 20% of heat can be lost through uninsulated floors according to the National Australian Built Environment Rating System (NABERS) website. This in itself presents a challenge for suspended flooring particularly given the rise of the 5 Star energy efficiency benchmark around Australia.

Conventional underfloor insulation systems are available, but there is the added challenge of dealing with moisture that gets trapped between the flooring and the insulation. For bulk insulation, moisture has a significant negative impact on performance. But regardless of the type of insulation, over time excess moisture can contribute to the growth of mould and lead to rising damp, potentially affecting both the flooring material and overall indoor health. Air-Cell Insulation, Australia's leading thermo reflective insulation manufacturer, has launched Permifloor™, an insulation innovation designed specifically for suspended framed floor applications delivering a 2-in-1 insulation and water-permeable moisture management solution.

Air-Cell Technical Manager, Mr. Keith Anderson, explains: "Permifloor™ is an ultra-thin physically cross-linked, closed-cell foam insulation sandwiched by highly reflective foil surfaces and perforated with tiny, evenly-spaced holes. These perforations allow water and vapour to permeate through preventing moisture that can often collect under flooring when using conventional underfloor insulation systems such as bulk insulation or rigid polystyrene boards."

Mr. Anderson adds that Permifloor™ also acts as an effective draught stop while improving energy efficiency. "By insulating your sub-floors you're preventing cold air draughts from leaking into the building, improving your indoor comfort levels. And the highly reflective foil surfaces of Permifloor™ re-radiate heat back in that would otherwise be lost through the floorboards, reducing the need for extra heating."

As with all of Air-Cell's products, Permifloor™ is fibre-free, non-allergenic, environmentally friendly and fast and easy to install. Permifloor™ has been stringently fire tested and complies with Australian Standards and BCA regulations.
