Our first product, Leadax Original, was introduced in 2017. It has the look and feel of traditional lead. It is also applied in the same way as lead sheet. In 2021, the self-adhesive lead substitutes Leadax Easy FA and Leadax Easy SA were introduced. Leadax Roov, the revolutionary sustainable roofing material, was launched in 2022.
Absolutely. You can book a demo on the Book a demo page. The demo is given free of charge so that you are completely ready to apply our products.
Leadax has ISO 9001:2015 as its corporate certification. Leadax Flashing has KIWA Covenant, BBA and DuboKeur certification, which establishes Leadax Original as the world’s most sustainable lead substitute.
Leadax’s products are made of recycled polyvinyl butyral (r-PVB), the plastic foil that was formerly used in safety glass, such as car windows. When a rock lands on a windshield it forms a star or a crack, but luckily the glass doesn’t break. This is because of the PVB. Since the PVB is able to withstand huge forces it also forms the perfect raw material for our waterproofing products. If it can take on a stone, you best believe it can also take on rain and wind.
Our products are made from recycled plastic waste (r-PVB). There’s a lot of this plastic waste available each year. In Europe alone, 1,5 billion kg of this waste is produced annually. This plastic waste used to be dumped or incinerated. A very unsustainable practice that’s harmful to our planet and its inhabitants. We want to make a change, so we use this plastic waste as raw material for our waterproofing products. After our product’s service life they can be recycled. The reclaimed raw materials are then reused for new Leadax products. This way, we’re closing the loop.
All 17 Sustainable Development Goals are important if we want to create a better and more sustainable future for everyone. We believe we can make an impact on the following goals:
You can read more about our dedication to the SDG’s on this page.
Yes, that’s possible. On the webpage Book a demo you can request a demo. There’s also an overview to check if there are demos in your neighborhood (if these are scheduled).
Yes, you can use a pair of Leadax scissors to cut Leadax Original to size, a Leadax dresser or a Leadax steel pressure roller to mould Leadax Original into place, Leadax high-tack sealant to create a watertight overlap, and Leadax fixing clips to fix Leadax Original into masonry joints.
Leadax Original can be applied on all lead code 5 applications, such as dormers, valleys, chimneys, and in cavity walls. Please note that when you apply Leadax Original on a flat or a low-slope roof, the edges and seams need to be sealed with Leadax high-tack sealant. Have a look at the Application Page for a complete overview of the places where Leadax Original can be installed.
Leadax Original truly is one of a kind. Contrary to other lead replacements, Leadax Original is applied in the same way you’d apply lead. This means that if you’re used to applying lead sheet you don’t have to learn any new skills to apply Leadax Original. You can use a lead dresser to dress it down into place, and a hot air gun or Leadax high-tack sealant to create a watertight overlap. Making use of the grid on the release liner, you can cut Leadax Original to size very easily.
Next to that, Leadax Original is available in roll lengths of 6 meters. The product can be applied in full roll lengths, without needing an overlap. This is because it doesn’t contain any heavy metals, so temperature changes have less of an effect on the expansion and contraction of the product.
Leadax Easy FA is our fully self-adhesive lead replacement. It is slightly thinner than Leadax Flashing Original, but just as strong. You don’t need many special tools to apply Leadax Easy FA, as the bottom part is covered with butyl.
Leadax Easy SA can be used on all lead code 5 applications, but because of its self-adhesive layer, we wouldn’t recommend installing it in instances where you’d normally use fixing clips, such as masonry joints. Instead, we recommend using Leadax Original. Common applications of Leadax Easy SA include dormers, valleys, chimneys, and window casings.
You just need a couple of tools to install Leadax Easy SA (hence its name!). You can apply Leadax Easy SA with just your hands, but for a perfect finish we recommend using a Leadax steel roller or Leadax dresser to mould it into place even further. If you want to create an overlap, we recommend using Leadax high-tack sealant. For detailed processing instructions, please visit this webpage.
Depending on your country’s and stockist’s availability, Leadax Easy SA is available in lead grey, black, white, copper, and terracotta in the following roll dimensions:
Leadax Easy SA can be installed with just a couple of tools. You can apply Leadax Easy SA with just your hands, but for a perfect finish, we recommend using a Leadax steel roller or Leadax dresser to mould it into place even further. Because it’s so light and thin it’s easy to carry it up onto a roof to install it. Your back will thank you.
The butyl is mounted on the PVB in such a way that it can be easily detached at the end of its service life, without making any concession to the adhesive strength during and after processing. This characteristic makes Leadax Easy completely demountable, recyclable, and thus circular. Various aging tests show that the butyl adheres well to the PVB to remain wind and water-resistant under various weather conditions for at least 30 years. An optimal adhesion is guaranteed on all dust-free substrates.
Leadax Roov can be used in combination with loose-laid ballasted systems, mechanically fixed systems, and fully adhered single-ply systems.
Leadax Roov can be used in combination with all types of roofs, such as off-white roofs, energy roofs, green roofs, water roofs and recreational roofs.
Leadax Roov was designed with the end user in mind. We want to make your job as fun and quick as possible. For this reason, a number of accessories were created, such as:
Please consult Leadax Roov’s product page for an overview of all the technical specifications.
The price of roofing varies greatly. There are cheap roofing materials available, but also very expensive ones. When you are looking for roofing, it is important to look not only at price, but also at factors such as quality, requirements of the project, longevity, color (whether it reflects or absorbs sunlight), aesthetics, and more.
Often, when it comes to roofing, people don’t look so much at just the price, but at the total cost of installation (TCI). For example, if you can install roofing smoothly without using too many accessories and man-hours, this will result in a lower TCI. Thus, there are many other factors that affect this. If you’re not sure, get advice from a technical advisor on which roofing material is most suitable for your project.
How you apply roofing depends on which roofing material you choose. For example, bitumen is burned on the roof, while Leadax Roov can be applied without an open flame. Here, it is sufficient to make an overlap with Leadax Bio Bind and Leadax PVB Liquid.
Before you begin removing the roofing membrane, it is important to see how it is attached. Is it loose-ballasted, (fully) bonded, or mechanically attached? It is also important to know exactly what roofing material was used. In the case of bitumen roofing, it may be that different layers have been applied over the course of decades.
Also, check where you can return the roofing materials. For example, can this be done at a local environmental service? Check with your municipality and be prepared before you remove your roofing. If you have a lot of waste you can also rent a construction container.
To find out which roofing material is best for you, you need to take different factors in account, such as:
Leadax Roov might be a right fit for your next project. You can request a free sample on this webpage.
Roofing or a roofing membrane is a protective layer applied to a flat or pitched roof to make it waterproof, snowproof and draft-free, so that the roof can protect against animals, heat, wind, and sunlight.
There are different types of roofing membranes. They all have their own set of unique features and depending on the project’s requirements it can vary heavily which one would work best for you. In general, roofing membranes last between 15 and 100 years. PVC typically lasts between 15 to 40 years, while zinc lasts between 70 and 100 years.
How a lead replacement should be applied depends on the type of lead replacement. Lead replacements are usually cut with a scissors and dressed down into place using a lead dresser or a roller. They’re held into place with a high-tack sealant or fixing clips. The application of self-adhesive lead replacements is slightly different though, as the self-adhesive layer sticks to the substrate. If you want to know how you can apply Leadax’s lead replacement, please visit this page.
Lead replacements usually have a number of benefits over using lead. For example, lead replacements require less overlap than lead. Because lead reacts strongly to temperature changes, an overlap should be made every meter. Lead replacements do not react as strongly to temperature changes, so you can often apply the entire roll in its full length immediately.
Lead replacements are also less prone to theft because they have no scrap value. Lead replacements are usually a lot lighter than lead.
Besides the fact that most lead replacements come in gray, other colors are also available, such as black, white, terracotta, and copper. Leadax’s lead substitute even looks exactly like lead in lead gray.
Another big advantage of lead substitutes is that you won’t get lead streaks on your roof tile or wall.
A lead replacement is used as a water barrier in building structures, such as walls, above window frames, on chimneys, and around dormers. A lead substitute is used primarily where different materials connect, such as the vertical masonry of a chimney (step flashing), on surrounding roof tiles, or the rising masonry of a facade that connects to a flat roof. It is mainly used in the outdoors, where it is often exposed to temperature changes. Lead replacements are made from various raw materials, such as PVB (Leadax), PIB, EPDM, and bitumen.
