Torch-on Membranes

What Is Torch-on Membrane?

Torch-on membrane is a type of waterproofing membrane that is flexible and environment-friendly. They protect a structure against dampness and moisture.  Torch-on waterproofing is reliable and effective for waterproofing projects as it has high resistance against tears and punctures.

This membrane roofing creates a strong membrane layer that consists of a blend of bitumen and polymer. It can be altered with Atactic Polypropylene (APP) and strengthened with a layer of non-woven polyester. Finally, the top of its surface is finished with a combination of mineral chips or sand and talcum. Moreover, a thin layer of Polyethylene foil is used as the under finishing.

Uses Of Torch-on Membranes

Torch-on membranes are a handy installation for commercial, industrial, and residential structures. It is used explicitly for waterproofing surfaces where water pooling or leakage typically occurs, such as green roofs. It is considered one of the best green roofing solutions, like butyl rubber membranes.

In addition, they are also helpful for basement applications providing a durable and high-quality waterproofing layer. It makes rarely checked or hard-to-reach areas like tanks and underground spaces impermeable.

Torch-on membranes are often applied to the following:

• Flat roofs
• Basements
• Terraces and balconies
• Underground car parks
• Walls and joints
• Structure foundation and slabs
• Tanks and tank linings

This membrane roofing can also be beneficial as an agent to repair roofs, cracks, and other structural leaks.

Benefits Of Using Torch-on Membranes

With its advantageous properties, torch-on waterproofing membranes offer a wide range of benefits:

• Torch-on membranes are taken as one of the most hard-wearing waterproofing solutions since they are adequate for various purposes like full water immersion. It is also considered suitable for sub-oil applications. If applied correctly, torch-on membranes can be relied on to provide a solution that leaves no leakage issues at all. Moreover, they can serve as a great use to seal gutters
• This membrane roofing also has an excellent insulation property like TPO membranes to be used as warm roofs. Adding a layer of the torch-on membrane will help regulate temperature and protect the surface from the harmful UV radiation 
• Some types of torch-on membranes contain photovoltaic cells, making them capable of storing solar energy
• Torch-on waterproof membranes are a sustainable and reliable green roofing solution as they help reduce a building's carbon footprint
• One reason contractors prefer it for waterproofing over any other material is that it meets global standards. Moreover, they have an extended lifetime. So, choosing a torch-on membrane is a good investment because they make a building sustainable and longer-lasting
• This waterproofing membrane is environment-friendly and safe
• The installation of this membrane roofing is easy and not much noisy. It will sound like any other activity being carried out in the area
• Torch-on waterproofing membrane can also block out harmful chemicals and toxins
• Lastly, these waterproofing membranes are non-biodegradable, non-carcinogenic, non-toxic, and non-water soluble

Types Of Torch-on Membranes

Torch-on Membranes are versatile products because of their manufacturing. They are usually available in two main types:

• Atactic Polypropylene Plastic modified asphalt (APP): This type of torch-on membrane is processed in an elastic-plastic way, making it flexible. It tends to tolerate high temperatures, so it is preferred to be installed in places where an enhanced sun and UV radiation protection is also required, besides waterproofing. In addition, APP is more accessible to apply than SBS sheets since it quickly melts on being heated with a torch.
• Styrene Butadiene Styrene (SBS): This type of torch-on membrane is manufactured with rubber-modified asphalt. This makes it more flexible than APP. As a result, it offers more elasticity in even cold temperatures. Since the contraction and expansion of this material stress well, it is suitable for fluctuating weather and temperature.

Both types of torch-on membranes have different properties, so experts may suggest choosing one over the other based on the varying conditions or requirements.

Installation Of Torch-on Membranes

As the name of the torch-on membrane suggests, its installation requires an open-flame propane torch. To install a torch-on membrane, a roofing professional lays out the sheets of modified bitumen onto the roof or surface where it needs to be installed. 

Then, a hand-held propane torch is used to heat the material, which adheres the torch-on waterproofing membrane to the surface. On reaching the right temperature, these layers start melting together, creating a waterproof layer over the surface which seals it.
