¿Qué es la lámina transpirable W-S AIR?

W-S AIR es una lámina impermeable al agua pero permeable al vapor de agua. Está diseñada para proteger cubiertas y cerramientos frente a filtraciones exteriores, al mismo tiempo que permite evacuar el vapor desde el interior.

¿Para qué sirve una membrana transpirable en un tejado?

Una membrana transpirable sirve para actuar como barrera frente al agua exterior y, a la vez, favorecer la salida del vapor de agua. Esto ayuda a proteger el aislamiento térmico y a mejorar el comportamiento de la cubierta.

¿W-S AIR es una lámina impermeable transpirable?

Sí. W-S AIR combina impermeabilidad al agua con permeabilidad al vapor, por lo que funciona como una lámina impermeable transpirable para cubiertas inclinadas y otros sistemas constructivos donde se necesita control de humedad.

¿Dónde se puede instalar la lámina transpirable W-S AIR?

W-S AIR está recomendada para cubiertas inclinadas y fachadas ventiladas. Se utiliza como protección bajo la cobertura exterior y como barrera frente a corrientes de aire, polvo e infiltraciones.

¿Se puede usar W-S AIR en cubiertas inclinadas?

Sí. W-S AIR está recomendada para cubiertas con inclinación superior al 6 %, donde actúa como protección secundaria frente al agua y como membrana transpirable bajo teja o cobertura.

¿Qué ventajas tiene una lámina transpirable frente a una lámina totalmente cerrada?

Una lámina transpirable permite evacuar el vapor de agua, lo que ayuda a reducir condensaciones dentro del sistema constructivo. Al mismo tiempo, mantiene la protección frente al agua exterior.

¿W-S AIR ayuda a proteger el aislamiento térmico?

Sí. Al actuar como barrera frente a corrientes de aire y humedad exterior, W-S AIR contribuye a mejorar la eficacia del aislamiento térmico en cubiertas y cerramientos.

¿La lámina W-S AIR ayuda a evitar la entrada de polvo e insectos?

Sí. Además de proteger frente al agua, W-S AIR ayuda a evitar la penetración de polvo e insectos en la cámara constructiva, mejorando el comportamiento global del sistema.

¿De qué está compuesta la membrana transpirable W-S AIR?

Está compuesta por un film microporoso de polipropileno con velo de no tejido en ambas caras, una estructura diseñada para ofrecer impermeabilidad al agua y difusión del vapor.

¿Por qué elegir W-S AIR para impermeabilizar tejados?

Porque es una solución ligera, resistente y fácil de instalar que protege la cubierta frente al agua exterior, permite la transpiración del sistema y ayuda a mejorar la durabilidad del tejado.

● TECHNICAL SHEETS

Breathable film
W-S Air

W-S Air is a waterproof and vapor permeable membrane designed for vapor control on pitched roofs and ventilated facades. It is installed under the protective layer and on the supporting structure, either supported on beams, boards (concrete, wood, panels) or directly on the thermal insulation.

Features that make the W-S Air film different

The breathable waterproofing membrane for roofs stands out for being resistant, lightweight and very easy to install. It is recommended for use on roofs with a slope of more than 5% as a breathable waterproofing and a barrier to air currents, improving the effectiveness of thermal insulation and preventing dust and insect infiltrations.

● FAQS

What is the W-S AIR breathable membrane?

W-S AIR is a membrane that is waterproof but permeable to water vapour. It is designed to protect roofs and enclosures against external leaks, while allowing vapour to escape from the inside.

What is a breathable membrane used for on a roof?

A breathable membrane acts as a barrier against external water while also allowing water vapour to escape. This helps protect thermal insulation and improves the performance of the roof.

Is W-S AIR a breathable waterproof membrane?

Yes. W-S AIR combines water resistance with vapour permeability, making it a breathable waterproof membrane for pitched roofs and other construction systems where moisture control is required.

Where can the W-S AIR breathable membrane be installed?

W-S AIR is recommended for pitched roofs and ventilated façades. It is used as protection under the external covering and as a barrier against air currents, dust and infiltration.

Can W-S AIR be used on pitched roofs?

Yes. W-S AIR is recommended for roofs with a pitch greater than 6%, where it acts as secondary protection against water and as a breathable membrane under tiles or roofing.

What advantages does a breathable membrane offer compared to a fully closed membrane?

A breathable membrane allows water vapour to escape, helping to reduce condensation inside the construction system. At the same time, it maintains protection against external water.

Does W-S AIR help protect thermal insulation?

Yes. By acting as a barrier against air currents and external moisture, W-S AIR helps improve the effectiveness of thermal insulation in roofs and enclosures.

Does the W-S AIR membrane help prevent dust and insects from entering?

Yes. In addition to protecting against water, W-S AIR helps prevent dust and insects from entering the construction cavity, improving the overall performance of the system.

What is the W-S AIR breathable membrane made of?

It is made of a microporous polypropylene film with non-woven fleece on both sides, a structure designed to provide water resistance and vapour diffusion.

Why choose W-S AIR for waterproofing roofs?

Because it is a lightweight, durable and easy-to-install solution that protects the roof against external water, allows the system to breathe and helps improve roof durability.

W-S Air breathable film

● TECHNICAL

Waterproof and vapor-diffusing membrane designed for waterproofing pitched roofs and ventilated facades. It protects the structure against the entry of water, dust and insects, while favoring the evacuation of vapor. It is recommended for roofs with a slope of more than 6% and can be installed directly over the thermal insulation, under a wooden structure and protected under a roof tile.

Multilayer structure formed by nonwoven / microporous film / nonwoven. Both the microporous film and the outer nonwoven are made of 100% polypropylene. It is a fully recyclable material, rot-proof and resistant to fungi and insects. It does not contain hazardous substances.
