What is Fastwarm®-Lite insulation?

Fastwarm®-Lite is a polyethylene, closed cell sound deadening foam insulation, with exceptional acoustic and high thermal properties.

Why should I use Fastwarm®-Lite insulation for carbon film heating?

Electric underfloor heating requires a high quality thermal barrier over the sub-floor to improve its efficiency, both in warm-up times and energy conservation: saving on operating costs.

Do I need insulation under my Carbonwarm® underfloor heating?

For improved performance in heating times and running costs, it is strongly recommended to install a layer of good quality insulation: this will minimise heat losses and ensure quicker heat-up times for the laminate/wood flooring.

Why does wood and laminate flooring need an acoustic insulation?

Due to their hard surfaces, floating laminate and wooden flooring require a sound absorbing, insulating underlay to reduce the transmission of impact noise caused through constant footfall over the flooring, creating a nuisance to people living below as well as inside the room.

Will Fastwarm®-Lite insulation help to reduce the footfall noise on my wooden flooring when walking over it?

Fastwarm®-Lite conforms to current building regulations Part E (Resistance to Sound) as measured to BS EN ISO 140-7 standards for acoustic emissions, where a low decibel rating is required for the flooring.

Fastwarm®-Lite is both suitable for new build properties and refurbishment projects where the wood or laminate flooring requires a low footfall impact sound.

What type of insulation should be used with wood and laminate floor heating?

Fastwarm®-Lite is the ideal solution under floating laminate, engineered wood and solid timber flooring, where a high degree of impact sound reduction is required to absorb the transfer of footfall noise and provide a high quality thermal barrier to improve the efficiency of the carbon film, electric underfloor heating system.

How is Fastwarm®-Lite supplied?

Fastwarm®-Lite is available in rolls:
5mm depth x 1m width x 5m or 25m lengths
10mm depth x 1.2m width x 5m or 25m lengths
Fastwarm®-Lite widths can be jointed using Fastwarm® fixing tape

Laying the Fastwarm®-Lite insulation rolls

Fastwarm®-Lite is easily cut and shaped to fit.

Due to its width, Fastwarm®-Lite is fast to lay: installation is completely dry and is a simple unrolling process; taping the insulation down to hold it in place using Fastwarm® fixing tape. 

Do I need to tape the Fastwarm®-Lite joints?

Tape along the edges of the Fastwarm®-Lite using the Fastwarm® fixing tape.
