Loft Conversions

When looking at increasing thermal efficiency of older properties, there is always a compromise between occupying internal space and achieving better U-values. Low-E® Insulation is ideal for all refurbishment projects from IWI (Internal Wall Insulation), to loft conversions and the refurbishment conservatories. Installed with little disruption, Low-E® Insulation is lightweight, quick, clean and very easy to install. Giving you maximum savings by reducing energy bills and carbon emissions while occupying as little as 20mm of internal space.

Loft Conversions

Is your Loft Conversion too cold in the winter and too hot in the summer. Make your loft the most comfortable room in your home with Low-E insulation. Non-toxic, indoor air quality approved and Class 1 Fire Rated, Low-E Insulation is quick, clean and easy to install. 


  • Increases Thermal Performance
  • Stops Draughts
  • No Fibres, no itching
  • Occupies less space
  • Won’t absorb moisture

"The Low-E was quick clean and easy to install. It occupied less than 30mm of space, so the room feels the same size. The room used to be too cold to sit in, now it’s easy to heat."

– Wendy R, Stockport

Below Rafter – Full Fill (Breather Membrane)

When installing a Mineral Fibre between rafters, it can be difficult to maintain an airspace on both sides of the Low-E® Insulation. In this example, Low-E® EZY Seal is installed with a full fill of mineral fibre between the rafters, before being counter battened and the finished ceiling is installed. It is important to maintain a sag on the breather membrane after the Mineral Fibre has been installed. A spacer batten may be required below the rafters to facilitate this.

Below Rafter – Partial Fill (Breather Membrane)

When refurbishing a roof with a breather membrane already in place, you may or may not require a spacer batten to install the secondary insulation while maintaining airspaces. In this example, a Rigid Foam insulation has been installed between the rafters, with Low-E® EZY installed under the rafters, before being counter battened and the finished ceiling is installed.

Below Rafter – Partial Fill (Roofing Felt)

Low-E® EZY can be used for refurbishment or upgrade work. When installing Low-E® EZY below rafter in a roof with no felt or a non-breathable felt, a 50mm ventilated cavity should be maintained between the underside of the roof and any additional insulation. Depending on the existing rafter size, you may need to fit a spacer batten to the underside of the rafter to create enough space for the additional insulation. Low-E® EZY should then be fitted to the underside of the rafters before being counter battened and the finished ceiling installed. This will stop draughting and air leakage which can be the biggest cause of heat loss in refurbished buildings.
