Butyl Tape Uses

One of the primary uses of butyl tape is in the construction industry. It is commonly used as a sealant for windows, doors, and roofs. The tape can be applied to the edges of the window or door frame, creating a waterproof seal that prevents water from entering the building. It can also be used to seal around vents, pipes, and other openings in the roof, preventing water from leaking into the building.

Butyl tape is also commonly used in the automotive industry. It is used to seal seams and joints in vehicles, preventing water from entering the interior. It is also used to attach body panels, trim, and other components to the vehicle's body.

Another common use of butyl tape is in the marine industry. It is used to seal hatches, portholes, and other openings in boats, preventing water from entering the vessel. It is also used to seal around fittings and other components on the boat's deck, preventing leaks and water damage.

In addition to its use as a sealant, butyl tape is also used as a bonding agent. It can be used to bond various materials together, including metal, glass, and plastic. It is commonly used in the manufacturing of solar panels, where it is used to bond the panels to the frame.

What is Butyl made up of?

Butyl tape is a type of sealing tape that is used for a variety of applications, including sealing, waterproofing, and soundproofing. It is made of a rubber-like material called butyl, which is highly effective in creating an airtight and watertight seal.

What industries is Butyl tape suitable for use in?

Butyl tape is used in a variety of industries, from construction and engineering to automotive and aerospace.

Versatility

One of the key benefits of butyl tape is its versatility. It can be used for a wide range of applications, from sealing windows and doors to creating a waterproof barrier for electrical connections. Butyl tape is also commonly used in roofing and roofing repair projects, as well as for sealing around pipes and ductwork. The tape is also used in the automotive industry to seal windshields, sunroofs, and other areas that are exposed to the elements.

Sealing and waterproofing

Butyl tape is an excellent choice for sealing and waterproofing projects because it is flexible and easy to work with. Unlike traditional sealing materials such as silicone or caulk, butyl tape can be molded and shaped to fit a variety of surfaces and shapes. This makes it an ideal solution for sealing around pipes and other irregular shapes.

Unlike traditional sealing materials, butyl tape does not contain harmful chemicals or solvents that can harm the environment. The tape is also easy to recycle and dispose of, which makes it a more sustainable choice for contractors and DIYers.

How to install Butyl tape?

When it comes to installing butyl tape, the process is relatively simple and straightforward. The tape is sold in rolls that can be cut to the desired length with a pair of scissors. To apply the tape, simply clean the surface where it will be applied and remove any debris or dirt. Then, peel the backing off of the tape and apply it to the surface, pressing firmly to ensure a good bond. The tape will form a seal that is both airtight and waterproof.

What type of applications is butyl tape not well suited for?

It is important to note that butyl tape is not suitable for all applications. For example, the tape is not recommended for use in high-pressure applications, such as those that involve the transfer of liquids or gases. Additionally, the tape may not be suitable for use in areas that are exposed to high temperatures, as the heat can cause the tape to deteriorate over time.

Questions people have asked us about these butyl tapes

Product questions for our 100mm x 1.5mm x 20 Metre Flashing Tape

Question: I will be undertaking a self-build project that is timber frame and timber clad. The windows I intend using are Andersen 400 windows (American company) with a nailing flange. In the instructions, they mention self-healing flashing and looking at various American web sites Tyvek Flex-wrap flashing for the sill and Tyvek straight flashing for sides and top are used. Whilst Tyvek flex-wrap is available in the UK only 150mm width is available not 250mm and Tyvek straight flashing is not available. Can you recommend a butyl flashing for weather protection and air leakage and that is self-healing butyl because some mechanical fixings on the vertical sections would penetrate the flashing? I look forward to hearing from you however if you need further information please do not hesitate to contact me. - Stephen

Answer: Morning Stephen, I feel that [this] flashing tape would help with this application as the adhesive is self-healing and 1.5mm thick. We do stock lead and white finishes in 200mm widths - Ian, Product Support Manager

Question: I need a flashing tape for sealing my polycarb roof to the wall. Is 200mm x 1.5mm x 10 Metres Flashing Tape the best choice? - Tony

Answer: Hi Tony, yes the 200mm would be perfect for this application, then simply decide on a facing colour of either white or lead - Ian, Product Support Manager

Question: Can this product stretch to form into corrugated roofing panels? - Live Chat

Answer: Hello, the product won't stretch as it is a butyl backed foil. It is very conformable though - Ian, Product Support Manager

Question: Will it bend sideways 90 degrees down the length of 100x125mm timber? ie form an upside-down U-shape; or will it crack or break at the bends? - Live Chat

Answer: Hello and thank you for your enquiry. The product would be fine for this application - Ian, Product Support Manager

Product questions for our: 150mm x 1.5mm x 10 Metre Flashing Tape

Question: Hi does this flashing tape do conservatories to brickwork? 99 % sure it does just making sure, as says washing machines and caravans - Wendy

Answer: Hi Wendy, yes this is the primary application for the flashing tape - Ian, Product Support Manager

Question: Hi there. I am in the process of replacing the roof for my conservatory with new polycarbonate. I see that this product is recommended for flashings for this type of work, which is great. I was looking at using something like DEKS KwikFlash or the Hambleside Danelaw FastFlash type products for the ridge and abutment flashings but wondered if you could tell me if the HS Butyl Flashing is the same specification as these products ie is its Aluminium stretch netting cast in polymer rubber for expansion and long term strength? I need a butyl backed flashing (definitely not bituminous!) that will not attack the polycarbonate sheeting. Am pretty certain this is the case with the HS Butyl but can you confirm for me, please? The abutment wall the flashing will go against is stone - again, can you confirm the HS Butyl will adhere satisfactorily to this, please? I should add that, in addition to the flashing tape for protection against water ingress, I will be dressing over the flashings with Code 4 lead, which will also help weather the butyl flashing. I am concerned, given they are quite a bit more expensive, that the KwikFlash or Fast Flash versions may be unnecessary 'over specify' in this scenario. If the HS Butyl meets the required specifications for the task in hand then it would be good to avoid what may be seen as an unnecessary expense! I would be most grateful for your thoughts regarding my enquiry and any advice offered would be warmly welcomed. Many thanks and best regards - Laurie

Answer: Good Morning Laurie, Thank you for your enquiry into the use of our flashing tape. I can confirm that this product is polycarbonate friendly and is used commonly for this type of application. The 1.5mm thick butyl adhesive is very aggressive and conformable, making it the perfect choice for creating a weather seal on uneven surfaces. The elasticity of the butyl will also allow for differential rates of expansion - Ian, Product Support Manager
