Room in Roof
DOMESTIC APPLICATIONS FOR LOW-E REFLECTIVE ALUMINIUM FOIL INSULATION
Is your Room in Roof freezing cold in the Winter and too hot in the Summer? Air leakage and draughts are widely regarded as accounting for more than 50% of energy consumption, while traditional insulations do little to tackle solar heat gain. Non-Toxic, clean and quick to install, Low-E® provides a vapour, thermal and air infiltration barrier all-in-one. With no airborne fibres and no itching, our environmentally friendly recycled Low-E® Insulation is indoor air quality tested and approved. Only 5.5mm thick, Low-E® is the thinnest most effective Insulation on the market. With minimal disruption and minimal loss of head height, Low-E® could make your Room in Roof the most comfortable room in your home.

Below Rafter – Partial Fill (Roofing Felt)
Low-E® EZ can be used for refurbishment or upgrade work. When installing Low-E® EZ 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® EZ 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.
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® EZ installed under the rafters, before being counter battened and the finished ceiling is installed.
Barn Conversions – Fully Exposed Rafter
Often the main objective of a project is to maintain and showcase the character of a building. When this happens there is always a compromise between meeting standards or prescribed U-values versus, maintaining character and limiting the amount of space occupied by the upgrade. In this example, the rafters have been left fully exposed. Low-E® PERF has been installed above a secondary insulation before being counter battened and the roof covering is installed.
Barn Conversions – Partially Exposed Rafter
Restrictions on roof heights can often mean it is not possible to maintain fully exposed rafters internally. In this example, Low-E® EZ has been installed over the top of the rafters and draped into the rafter cavity. A secondary insulation is then installed over the top of the rafters and the finished ceiling is then fitted between the rafters with the use of small timber battens.
