Membranes & Airtightness

Buildings need, not only to be protected from energy loss, but also from air leakage and the weather. Sheep Wool Insulation supplies a range membranes and airtightness products that are suitable for use with our insulation.

External Membranes

The VIVAP range of breathable membranes allow moisture to escape from the building, while at the same time, protecting from the elements.

VIVAP Allround is a single membrane solution for your entire construction. Allround is the only membrane you will need for use in both the roof and walls. Allround is suitable for use in ventilated and non-ventilated construction types and is a lightweight, tear resistant and easy to install membrane. It's impresive specification ensures the highest protection against rain and the elements, while maintaining high vapour permeability.

Airtight Membranes

The LUP range of airtight membranes ensure allow moisture to escape from the building, while at the same time, protecting from the elements.

LUP Actiroll is a breathable vapour check used to ensure an internal airtight seal. Actiroll is part of the LUP airtight system for controlling airflow in a building. Airtight systems maximise the thermal efficiency of insulation in buildings by removing leaks which lead to heat loss. Actiroll is used in conjuction with LUP tapes and glues.
LUP Blueline is is a non-breathable polythene vapour check used to ensure an internal airtight seal. Blueline is part of the LUP airtight system for controlling airflow in a building. Airtight systems maximise the thermal efficiency of insulation in buildings by removing leaks which lead to heat loss. Blueline is used in conjuction with LUP tapes and glues.
LUP Tapes & Glues form part of the LUP airtight system. Consisting of LUP Cral, a yellow tape for sealing overlapping layers of airtight vapor checks & barriers, LUP San, a highly elastic adhesive tape for airtight sealing of service penetration and LUP Mur, an elastic, permanent and self adhesive glue for sealing vapour barriers/checks to rough surfaces like plaster, concrete and timber.
