Vapr-Free Blue Breather Membrane

Breathable & Fully Waterproof Protection

Vapr-Free Blue Breather Membrane is a high-quality, breathable membrane designed for use in pitched roofs and wall applications. It allows moisture vapour to escape from the building structure while remaining fully waterproof, helping to protect against wind-driven rain, dust, and condensation.

Designed to Let Buildings Breathe

Engineered to improve airflow and moisture control, Vapr-Free Blue helps the building fabric breathe naturally, reducing the risk of trapped moisture and long-term structural damage. This makes it an excellent choice for both new-build and refurbishment projects where reliable weather protection is essential.

Easy to Handle & Install

Supplied in a practical, easy-to-handle roll size of 1m x 50m, Vapr-Free Blue is lightweight and straightforward to install, helping to speed up installation on site while maintaining consistent coverage and performance.

Upgrade for Higher Thermal Performance

If you’re looking for enhanced thermal performance, we also offer YBS BreatherQuilt Insulation, which combines breathable membrane technology with added insulation to deliver improved heat retention while still allowing the building to breathe.
