The most breathable membrane
Membranes that are the most breathable are known as air open and vapour permeable. These types of extraordinarily breathable membranes have been developed through extensive testing and innovation over the years. All Kingway membranes are put through a series of rigorous tests, utilising specialist equipment to prove performance claims. Kingway also puts a great emphasis on durability, with additional accelerated ageing tests designed to ensure the product will continue to perform in the future.

While these types of membranes do come at a premium, they are growing in popularity. Being both air open and vapour permeable minimises the risk of condensation forming, particularly during the drying out period of a building. This provides extra reassurance for building and roofing contractors that problems with condensation during this vulnerable time can be avoided, in addition to simplifying the ventilation design and installation process.

Another key benefit of using an air open vapour permeable membrane is that they are ideal for complex roofing designs with lots of breaks in the roof line structure, such as skylights or compartmentalised roofs for apartment complexes. More design freedom is made possible in these scenarios, as by opting for a membrane like this means that the roofing design does not need to factor additional ventilation.

Another practical use for the most breathable membrane would be to support a roofing contractor tasked with ventilating the roofs of a 'lean to' extension at the rear of a property. Often it is a struggle to install high-level ventilation in these scenarios. By choosing an air-open vapour-permeable membrane, this problem is conveniently solved while remaining compliant and effective.

For buildings that require a certain roofing aesthetic, a traditional mortar ridge line, instead of the modern dry ridge system, could be a requirement. In these instances, where you cannot fix any ventilation through the ridge line, having a vapour-permeable membrane to take care of the
ventilation is advantageous.

FAQS

1. What is the difference between breathable and non-breathable roofing felt?
Non-breathable felt acts as a complete barrier and requires ventilation below to prevent condensation. Breathable membranes contain a microporous film that allows moisture vapour to escape while still repelling water.

2. Do I still need ventilation when using a breathable membrane?
Breathable membranes greatly reduce condensation risk, but most roofs still require some ventilation at the eaves and ridge to meet building regulations and manage residual moisture.

3. How long will a breathable membrane last?
When properly installed and protected by the roof covering, breathable membranes can last for several decades. Their lifespan may be reduced by prolonged UV exposure, incorrect fixing or mechanical damage, so always follow the manufacturer's instructions.

4. What weight of membrane should I choose?
Lightweight membranes (100–120 gsm) suit sheltered domestic roofs, mid-weight options (130–160 gsm) are ideal for standard homes and extensions, and heavy-duty membranes (160 gsm+) are best for exposed or commercial settings.

5. Which way up do I lay a breathable membrane?
Most membranes have a printed or darker side that should face upwards during installation. This side offers better UV resistance. However, since most are vapour-open on both sides, performance is not significantly affected if installed the other way up.
