ODE Lunaflex Loft Roll Ultra 42 Insulation
Glass Mineral Wool Loft Roll for Thermal and Acoustic Insulation
ODE Lunaflex Loft Roll Ultra 42 is a glass mineral wool loft insulation roll designed for use at ceiling level in cold loft spaces. It provides thermal insulation while also helping absorb sound within roof and ceiling voids.
The roll is pre-cut for easier fitting between common ceiling joist centres, helping reduce cutting time, waste and installation effort. It is suitable for loft floors, roof spaces and ceiling insulation upgrades where a lightweight, non-combustible mineral wool roll is required.
ODE Lunaflex Loft Roll Ultra 42 has a thermal conductivity of 0.042 W/mK and is manufactured with more than 80% recycled glass content. It is also classified as A1 non-combustible to EN 13501-1.

Installation notes
Install ODE Lunaflex Loft Roll Ultra 42 between ceiling joists in cold loft spaces. The roll can be laid between joists and cross-laid above the joists where additional insulation depth is required.
Do not compress the insulation unnecessarily, as this reduces thermal performance. Keep ventilation paths clear and avoid covering recessed lights or electrical fittings unless they are correctly protected.
For acoustic use, ensure the roll fully fills the void with no gaps, as gaps reduce sound absorption performance.
FAQ
What is ODE Lunaflex Loft Roll Ultra 42 used for?
It is used for insulating loft floors and ceiling-level roof spaces. It helps improve thermal performance and can also absorb sound within ceiling voids.
What thicknesses are available?
The main options are 100mm, 150mm and 200mm.
What does Ultra 42 mean?
The “42” refers to the thermal conductivity value of 0.042 W/mK.
Is it non-combustible?
Yes. ODE Lunaflex Loft Roll Ultra 42 is glass mineral wool and is classified as A1 non-combustible.
Can it help with soundproofing?
It can help absorb sound inside loft or ceiling voids, but it should not be sold as a full soundproofing system by itself. For stronger ceiling soundproofing, it should be combined with acoustic boards, isolation, sealant and proper flanking control.
