Insulation Tapes

Insulation tape covers the seams between insulation boards. Aluminium foil tape eliminates pockets of air between boards and protects against moisture. By investing in aluminum tape, you can ensure the longevity of your insulation materials for years to come. We stock popular aluminium foil tape that is designed to cover the seams between PIR insulation boards. It is available in 50mm, 75mm, and 100mm widths.

What Is Insulation Tape?

Insulation tape is a common construction accessory. You do not need tape for insulation boards, but it is recommended. It is designed for installation across the seams between boards. Some people even place the tape over seams that are between boards and frameworks like joists and studs. 

Tape functions as a barrier. If tape is installed correctly, it eliminates air pockets. Air pockets can impact the effectiveness of your insulation boards. Insulation boards are most effective when they are laid flush against each other. Tape holds the boards in place, which can also help to minimise migration in insulation build-ups that are not secure.

Like sellotape, foam insulation tape comes in a handheld roll. You can simply roll the tape directly onto the board. The installation process is very simple and can increase the lifespan of your insulation materials.

Aluminium Foil Tape 

Aluminium foil tape is the most popular type of tape that we offer. It has lots of different names including thermal insulation tape as well as foam and silver foil tape. This type of tape is made from  soft aluminium foil and is manufactured with a flame retardant adhesive. You do not need to worry about aluminium tape contributing to the risk of fire in your build-up of materials.  

Foil-backed tape is designed for installation on all types of foil-faced insulation. It is most commonly used in conjunction with PIR insulation boards, but it will stick to almost any material. We stock a popular 45m roll of silver foil tape. It is available in 50mm, 75mm, and 100m widths.

Foil insulation tape is not waterproof, but it does act as a barrier against moisture. When moisture infiltrates insulation build-ups, it can cause a number of problems. It can impact the effectiveness of the insulation and even cause unsecured insulation to drift. Aluminum tape is a cheap, simple extra option for people who want to guarantee the longevity of their expensive insulation materials. 


Tyvek Acrylic Tape 

We stock Tyvek Single-Sided Acrylic Tape and Tyvek Double-Sided Acrylic Tape. Both rolls are made from Tyvek HDPE and acrylic adhesive. Unlike the silver insulation tape that we stock, Tyvek tape boasts waterproof properties. It has a strong, secure hold that can withstand large downpours. Acrylic insulation tape also acts as a barrier against air. Reduced air leakage leads to better energy efficiency. 

Double-sided tape is ideal for people who want to create a build-up of insulation materials. You can apply it directly to the material. Tyvek tape has a strong tack, which will stay secure in even the most humid environments. You can place another board or membrane on top and depend on Tyvek for a superior hold.

Frequently Asked Insulation Tape Questions


Benefits of Insulation Tape

There are lots of advantages of buying tape for insulation seams.

Thermal performance – Whether you are buying tape for foam board insulation or a membrane, you are protecting the thermal performance of your materials for years to come. When strong tape is placed over the seams between insulation boards, it acts as a barrier for air. Hot air cannot escape through the cracks. Both acrylic adhesive tape and foil-backed tape can improve the thermal envelope of your home. 

Moisture resistance – Acrylic and foil tape are both moisture resistant. Moisture can compromise the structural integrity of your insulation materials. Moisture is the first step towards rot and mould. Buying tape for insulation seams can prevent moisture from becoming a much larger problem. Tyvek tape is water-proof, whereas aluminum foil can only protect your materials against small amounts of moisture. 


What Is Insulation Tape Used For?

Most people buy tape for insulation seams. Insulation boards should always be flush. There should never be a gap between insulation materials. Large pockets of air can reduce the efficiency of the materials. Even when boards are side by side, there is still a seam. Tape seals the seam and eliminates the chance of air or moisture infiltrating the space between your insulation materials. 

You can also place insulation tape over the seam between insulation boards and frameworks like rafters, studs, and walls. We recommend placing tape on every type of seam. The more you cover the seams, the better the thermal envelope of your home. 


What Type of Tape to Use on Foam Pipe Insulation?

We recommend using insulation tape to secure foam pipe insulation. Foam pipe insulation protects your pipes from extreme temperature changes. Extremely cold air can impact the surface of pipes. Foam pipe insulation also eliminates humidity and pipe sweating. 

Aluminium foil tape and Tyvek acrylic tape are the two most popular types of tape that we stock. They can secure the foam pipe insulation. They also act as a barrier against cold air, which ensures the longevity of your insulation materials for years to come. 


How to Tape Insulation Seams?

Installing tape for insulation seams is very easy. The tape comes in rolls, which makes it easy to handle and manipulate. Hold the roll close to the seam, find the end of the tape, and apply it directly to the seam. From there, you can unwind the roll and smooth the tape onto the seam as you go. 

It is important to apply tape to the end of the seam. You should aim to cover all the places where the two insulation boards meet, even the corners if applicable. If you leave gaps, the tape will not have the same impact. This applies to all the types of tape that we stock.
