Powerlon UltraPerm Lite Vapour Permeable Roofing Felt is a lightweight, high-performance breathable roofing underlay designed for use across a wide range of pitched roof constructions and timber frame walls.
Manufactured from a non-woven composite membrane, UltraPerm Lite combines exceptional water vapour permeability with hydrophobic, water-repellent characteristics and good UV stability. This allows moisture vapour from within the roof or wall construction to escape while helping protect the building envelope against external moisture.
Powerlon UltraPerm Lite can be used on warm and cold roofs, supported and unsupported applications, and ventilated or unventilated roof constructions, making it a versatile breather membrane for new-build and refurbishment projects.
The membrane is BBA certified for roofs and walls, CE marked and tested to BS 5534:2014+A1:2015. Supplied in a 1m x 50m roll, each roll provides up to 50m² of coverage.
Powerlon UltraPerm Lite is designed for use as a vapour-permeable roofing underlay and timber frame wall membrane.
Suitable applications include:
Its lightweight construction provides a practical solution for projects requiring the breathability and weather protection of the UltraPerm range in a 92gsm membrane.
Powerlon UltraPerm Lite provides exceptional water vapour permeability, allowing moisture vapour from within the building construction to pass through the membrane.
Effective vapour transmission helps manage moisture within insulated roofs and timber frame walls by allowing water vapour to escape rather than becoming trapped within the building envelope.
This makes UltraPerm Lite suitable for modern roof constructions where effective moisture management is an important part of the overall roof design.
Powerlon UltraPerm Lite can be used across a variety of pitched roof constructions, including:
This flexibility makes UltraPerm Lite a versatile roofing underlay for builders, roofers and developers working across a range of roof designs and specifications.
At 92gsm, Powerlon UltraPerm Lite provides a lightweight option within the UltraPerm range while retaining the tough, durable and tear-resistant characteristics required for professional roofing applications.
Its low weight makes the membrane straightforward to handle, position and install across roof and wall areas.
The 1m roll width also provides a convenient format for handling on pitched roofs and other applications where a narrower roll may be preferable.
In addition to its high vapour permeability, Powerlon UltraPerm Lite provides hydrophobic, water-repellent characteristics.
This allows moisture vapour from within the roof construction to escape while helping resist external water.
The membrane therefore combines breathability with weather protection as part of a correctly designed and installed roof or wall system.
Powerlon UltraPerm Lite also provides good UV stability, offering additional resistance during normal installation and construction periods before the permanent roof or wall covering is completed.
The membrane is supplied with a black finish, distinguishing the Lite grade within the Powerlon UltraPerm range.
Powerlon UltraPerm Lite is BBA certified for roof and wall applications, providing independent certification for its intended use within suitable building constructions.
The membrane is also CE marked and has been tested to BS 5534:2014+A1:2015, making it suitable for professionally specified pitched roofing applications.
Powerlon UltraPerm Lite has a Class E reaction to fire classification.
Combined with its vapour permeability, water-repellent characteristics, good UV stability and versatile installation options, UltraPerm Lite provides a practical lightweight underlay for a broad range of roof and timber frame wall applications.
