Applications & Construction
What is the difference between W1 and W3?
W1 is important for a vertical wall membrane as it is the highest level of water protection that is specified under the ISO or EN standards for water protection and penetration. W3 is the lowest level of water protection given to a product where water could easily penetrate from rain on the outside of a building, resulting in damp or mould behind the cladding and membrane.
Why not just use Euroclass A1 membranes?
The A1 only membrane was developed as a fire protection only for closed cladding. It is based on a fibre glass weave only. A1 membranes are not water proof to W1, and have the potential of the weave breakdown with extended UV rays before the cladding is fitted over the membrane.
How much more expensive is an Eurolass A2 membrane over Eurolass B?
Euroclass B membranes were developed to give some form of fire protection behind cladding,however they can ignite and give off considerable toxic smoke in a fire, unlike todays Eurolass A2-s1,d0 membranes. The manufacturing process and the used raw materials of an Euroclass A2 membrane with high fire protection and W1 water protection means the cost of manufacture is substantially higher than an Euroclass B but has the benefit of life and building safety way above an Euroclass B.
Can I use membranes on circular façade profiles?
This will be dependent upon the tightness of the building profile. The Stamisol Safe One being of a flexible material can be used on circular profiles, but you must be careful of and creasing of the membrane around the profile that may then be needed to be cut and covered with a Stamisol Safe One patch around the cut area to give the full membrane protection. The patch process can be found in the technical data of fitting of Safe One.
Can I use the membrane as a vapour membrane?
The Stamisol safe One was designed and manufactured as a vertical wall membrane and not a water vapour membrane. The design and manufacturing process of a vapour membrane is different due to its product requirements.
Can I use the membrane in high humidity conditions?
Stamisol Safe One was developed for both water protection and breathability, therefore is highly suited for high humidity conditions, however you must be aware that placing this membrane over materials that have high water content due to rain or humidity may be drawn out of the material and give dry protection if water is already present. Site conditions should be taken into consideration.
Do you test the membrane on Euroclass A2 wall systems?
The Stamisol Safe One membrane was developed and independently tested in its own right as the structure that the membrane can be fixed to may vary. Therefore, an outer wall system can vary. If a company has an order to place over 5000 sqm then Stamisol would be prepared to test on behalf of the client the A2 system with the membrane attached. However, they can give no guarantee that the sample material that must be supplied by the customer meet an Euroclass A2 specification, only the membrane itself.
When will ADB be changed to only use Euroclass A2 membranes behind cladding?
We are working hard to inform DLUCH (Department of Levelling up, Communities and Housing) of the changes required in ADB part 4 to remove membranes from being exempt from an A2 wall system now that Euroclass A2-s1,d0 membranes are available. We are currently awaiting a response to when updates to ADB will take place hopefully within 2023.
Can I use the membrane on buildings with a preservation order?
Stamisol Safe One has been used both below and above ceilings as part of a fire protection system and water and damp protection due to its W1 and breathability attributes. However, the decision is that of the Architect and consultant as to their requirements and application.
What A2 colours can I have for open façades?
Currently A2 membranes are only manufactured in black as the initial colour. This in part is due to ensuring the colour pigments can maintain its W1 properties with high UV protection. Independent development of colours and testing is an extensive time frame, but it is envisaged that other colours will be launched during Q4/2023.
When will colour membranes be available in Euroclass A2?
Colour membranes are currently under development to meet the A2-s1,d0 specification. Due to the development and test time required it is not envisaged to have the next colour after black available in Q4 2023.
Glueing & Installation
How do I fix the membranes together?
It is recommended that the Stamcoll Safe glue is used with an overlap to hold the membrane in place. This glue will ensure a good level of contact required when fixing the membrane in place. Stamcoll N55 glue can be used for on the back side of the wall to the membrane.
Which glue do I have to use?
If you have a black side at glueing, use the black glue (Stamcoll Safe), if you glue the fibreglass side you can use both (Stamcoll Safe or Stamcoll N55 for fast fix).
Can I use any glue to fix the membranes together?
Using a glue that is not specified by Stamisol is dangerous and not recommended. Glue not approved by Stamisol, would not be covered under the membrane warrantee. It is a risk to use a non–tested Stamisol glue in regard to aging and bonding.
Where do I get the fixing plates or battens from?
Fixing plates and battens are generally supplied and fitted by the installer based upon the building design and Architects requirements as each building is different utilising different building materials. A competent and experienced Installer will know what fixings are required to hold the membrane.

Applications Façades A2Stamisol Safe One can be used both for closed and partially open vertical façades with up to 50 mm joints or an open area up to 50 % especially for apartment blocks higher than 11 meters, hospitals, retirement homes, rehab centres, universities, schools, nurseries and building floor extensions.Read more...
A new need for fire safetyIn buildings higher than 11 m or high-risk buildings, where mobility may be an issue, fire-fighting control and evacuation is only possible to a limited extent. In order to develop future-oriented concepts in fire safety, the façade membrane is an essential element when incorporated into a wider fire engineering strategy.Read more...
