Resistant to
long-term
uv-radiation
An UV-resistant membrane is designed to remain waterproof even after prolonged exposure to UV radiation. In the case of open façade structures or poorly sealing tiled roofs, the façade cladding or roofing is not completely sealed and a regular membrane, due to UV radiation, will lose its effect over time. The UV resistant membranes have been tested for an extremely long time in climate cabinets equipped with UV lamps and are thus guaranteed to provide the right protection.
Effective
UV protection
One of the main causes that affect the effectiveness of roof and facade membranes is exposure to UV radiation. This can occur either during the open construction phase or when the membrane is applied in a partially open façade or poorly closing tiled roof. An UV-resistant membrane is a breathable and waterproof membrane that resists the effect of UV radiation. Because this building membrane thus often remains partially visible, even after application, it is always black in color and has no printing. UV-resistant membranes are wind and watertight but at the same time breathable. In this way, the membrane ensures that moisture (rain) from the outside cannot affect the structure while moisture from the inside can be drained away. This will protect the structure from mold and wood rot while maintaining the effectiveness of the insulation.
The main advantage of UV-resistant films is that they retain their effect even when exposed to UV radiation for a long time. In addition, we have UV resistant membranes with a fire class B which also allows them to be used in wooden facade constructions. Due to its UV resistant nature, the open construction phase of this type of membrane is often longer than standard membranes but when long-term durability must be guaranteed, the processing time is not unlimited. This means that the finish of the facade insulation or roof insulation should be confirmed up to 4 months after application of the membrane.

In these types of constructions
you use a UV resistant membrane
The UV-resistant insulating membrane is used on the outside of a roof or facade construction. A UV-resistant membrane is used when the structure faces permanent UV exposure. This can be the case when roof tiles close poorly such as with old Dutch roof tiles or with a partially open exterior wall. With an open facade system, the facade does not completely close the structure, allowing good ventilation of the space behind the structure. But because the façade is not completely sealed, the structure is also exposed to the sun and other weather elements. Therefore, in this case, it is essential that the membrane used is not only waterproof to stop rain but also that it does not lose its effect when exposed to UV radiation. For this reason, UV-resistant membranes have a special functional layer to ensure waterproof and breathable functionality.
Important things to know about
an open facade
In the case of an open façade system, it is important that the area between the open sections does not exceed 20% of the total area of the façade. In addition, the space between the gable sections should not exceed 20 mm in width or height. Make sure that there is an air cavity of at least 20 mm between the membrane and the cladding. Finally, it is important to allow 10 cm of membrane to pass through at the bottom and tape it to the underlying structure with the appropriate facade tape.
This is how you process
a UV resistant membrane
UV-resistant films are used on the cold side of structures where the black side must always face the outside. The foil should be applied tile by tile with a horizontal overlap of at least 15 cm. To ensure the effectiveness of the film, it is essential to tape the overlaps and staples with special UV-resistant tape such as VAST-R® Facade tape or Tyvek® Facade tape.
We recommend attaching the UV-resistant foil to the structure with stainless steel staples and then placing the (fabric) battens over the staples. It is important to first attach VAST-R® nail sealing tape or VAST-R® Butyl tape under these (fabric) tiles. This ensures that the screw-hole connection remains watertight and the effectiveness of the film is not compromised.

Frequently Asked
questions
What is a Uv-resistant membrane?
A UV-resistant membrane is a type of insulation membrane designed to resist the harmful effects of ultraviolet (UV) radiation from the sun.
What is a UV-resistant membrane used for?
A UV resistant membrane is specifically used as an insulation membrane on the outside of roofs and facades. This membrane is used when the structure is continuously exposed to UV radiation.
What are the benefits of a UV-resistant membrane?
One of the main advantages of UV-resistant membranes is that it retains its protective effect even with prolonged exposure to UV radiation. In addition, we have UV-resistant membranes with fire class B, making them also suitable for use in wooden façade structures. Thanks to their UV-resistant nature, these membranes often have a longer open processing time than standard membranes. However, it is important to note that although long-term durability is ensured, the open construction phase is not unlimited.
How long does a UV-resistant membrane last?
The life of a UV-resistant membrane can vary depending on several factors, such as the quality of the membrane, exposure conditions and maintenance. In general, high-quality UV-resistant membranes can last several years to decades. However, it is advisable to consult the manufacturer’s specific warranty and product information for an accurate estimate of the lifespan.
Can a UV-resistant membrane help reduce heat transfer?
Yes, UV-resistant membrane can help reduce heat transfer. In addition to blocking harmful UV radiation, the membrane can also reduce infrared radiation (heat radiation). This helps create a more comfortable indoor environment and can help save energy by reducing the burden of air conditioning.
Can a UV-resistant membrane be cut to size?
Yes, a UV-resistant membrane can be cut to size. This allows for precise application of the membrane and ensures optimal coverage and protection from UV radiation.
