Powerlon UltraPerm Premium Breather Membrane Roof Felt is a high-performance, vapour-permeable roofing underlay suitable for a wide range of pitched roof and timber frame wall applications.
Manufactured from a non-woven composite membrane, UltraPerm Premium combines exceptional water vapour transmission with hydrophobic, water-repellent characteristics and good UV stability. This allows moisture vapour to escape from the roof or wall construction while helping protect the building envelope against external moisture.
Powerlon UltraPerm Premium 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 Premium is designed for use as a breathable roofing underlay and timber frame wall membrane.
Suitable applications include:
Its versatile construction allows the membrane to be used across a broad range of roof designs and suitable wall applications.
Powerlon UltraPerm Premium provides exceptional water vapour permeability, allowing moisture vapour from within the building construction to pass through the membrane.
This helps manage moisture within insulated roof and timber frame constructions, reducing the potential for unwanted moisture accumulation within the building envelope.
The breathable construction allows water vapour to escape while the membrane’s hydrophobic characteristics help resist external water.
Powerlon UltraPerm Premium is suitable for a wide variety of pitched roof constructions, including:
This flexibility makes UltraPerm Premium suitable for roofing contractors, builders and developers working across different roof designs and specifications.
Powerlon UltraPerm Premium is manufactured from a tough non-woven composite material designed to provide strength and durability during installation.
Its tear-resistant construction helps the membrane withstand the handling and installation demands associated with professional roofing and timber frame applications.
At 135gsm, UltraPerm Premium provides a durable yet manageable membrane for both roof and wall installations.
The membrane combines excellent breathability with hydrophobic, water-repellent characteristics.
This helps protect the underlying roof or wall construction against external moisture while still allowing water vapour from within the building envelope to escape.
Powerlon UltraPerm Premium also offers good UV stability, providing additional protection during normal construction and installation periods before the permanent roof or wall covering is completed.
Powerlon UltraPerm Premium 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 roofing projects.
Powerlon UltraPerm Premium has a Class E reaction to fire classification, adding to its performance characteristics as a professional roof and wall membrane.
Combined with its water-repellent properties, vapour permeability, durability and versatility, UltraPerm Premium provides a practical membrane solution for a broad range of building envelope applications.
