Supex 100 Gun Grade PU Foam Sealant is a one-component polyurethane foam designed for gap filling, sealing and insulation.
It expands after application to fill suitable gaps and cavities. It also helps reduce unwanted air movement and provides thermal and acoustic insulation.
The gun-grade design allows you to control the foam flow during application. This makes it a practical choice for contractors, installers, builders and professionals who need greater control over foam dispensing.
Use it for suitable gaps around door frames, window frames, service openings and other compatible construction components.

When sealing construction gaps, application control matters.
Supex 100 Gun Grade PU Foam Sealant is designed to help professionals apply expanding foam where it is needed.
Controlled Foam Application
A compatible PU foam gun lets you regulate the amount of foam dispensed. This helps you apply the product more precisely and reduce unnecessary waste.
Effective Gap Filling
The foam expands after dispensing to fill suitable gaps, joints and cavities. Allow enough room for expansion to avoid overfilling.
Thermal Insulation
Foam can help reduce heat transfer through suitable gaps and openings. The overall result depends on the construction assembly and installation quality.
Acoustic Insulation
Sealing gaps can help reduce unwanted sound transmission through openings. Actual acoustic performance depends on the surrounding structure.
Strong Adhesion to Compatible Surfaces
Polyurethane foam adheres to many common construction materials. Always check substrate compatibility and preparation requirements before use.
Suitable for Repeated Professional Work
The gun-based dispensing system is useful for installers who need controlled application across multiple gaps or work areas.

Supex 100 can be considered for a range of suitable construction and insulation applications.
Gaps between door frames and surrounding walls can allow unwanted air movement.
Expanding PU foam helps fill suitable gaps around the frame. Apply it carefully to avoid excessive expansion that could affect frame alignment.
Window installations may leave gaps between the frame and the wall.
Gun-grade PU foam allows controlled dispensing into these spaces. Check the frame manufacturer’s recommendations before application.
Construction joints between masonry walls, beams and adjoining components may require suitable gap filling.
PU foam can help fill compatible cavities and reduce air leakage. Select the correct product for the joint’s movement, exposure and performance requirements.
Openings around air-conditioning pipes and cables can allow outside air and dust to enter a building.
PU foam can seal suitable openings around service lines. Use an appropriate firestop system where penetrations pass through fire-rated walls or floors.
Certain gaps around service entries and compatible enclosures may require sealing.
Check the electrical installation requirements and product suitability before use. Do not apply foam where it could interfere with equipment, ventilation or required electrical clearances.
Commercial buildings and industrial facilities may have gaps around panels, frames, ducts and other building components.
Gun-grade foam can help fill suitable cavities where polyurethane foam is an appropriate sealing material.
Unsealed openings can contribute to unwanted heat transfer and sound transmission.
PU foam can help seal suitable gaps as part of a wider insulation solution. Results depend on the assembly and application method.

Not sure whether to choose gun-grade foam or a standard aerosol can?
Both use expanding polyurethane foam, but their dispensing systems and typical use cases differ.
| Feature | Supex 100 Gun Grade | Standard Can PU Foam |
|---|---|---|
| Dispensing method | Dedicated PU foam gun | Straw or adapter |
| Foam flow control | Controlled through the gun trigger and flow adjustment | Generally less precise |
| Application accuracy | Suitable for controlled dispensing into gaps | Suitable for straightforward gap filling |
| Repeated applications | Convenient for professional, repeated use | Convenient for smaller or occasional jobs |
| Application speed | Useful for repeated work across multiple gaps | Convenient for quick, smaller tasks |
| Equipment required | Compatible PU foam gun | Usually no separate gun when using a straw |
| Best suited for | Contractors, installers and regular users | Occasional users and smaller applications |
| Cleaning and maintenance | Gun maintenance may be required | Straw and valve handling depend on the can design |
Choose gun-grade PU foam if:
Choose a standard aerosol can if:
The best option depends on the job size, application frequency and level of control required.
Explore the alternatives:
Correct application helps improve adhesion, curing and foam performance.
Follow the product label and the latest technical data sheet.
Remove dust, grease and loose particles from the application area.
Check that the surface is compatible with polyurethane foam. Avoid applying the product to unsuitable materials such as silicone, polyethylene or PTFE unless the manufacturer confirms compatibility.
Wear suitable gloves, eye protection and protective clothing.
Ensure adequate ventilation. Read the product safety data sheet before use.
Use a compatible PU foam dispensing gun.
Check that the gun is clean and in good working condition. Follow the gun manufacturer’s instructions for fitting the can.
Shake the can thoroughly before use, following the instructions on the label.
Secure the can to the gun as directed. Check the connection before dispensing.
Use the gun’s trigger and flow-control mechanism to regulate dispensing.
Start with a small test application on a suitable surface. This helps you understand the foam flow and expansion before filling the target gap.
Position the nozzle near the gap and dispense the foam slowly.
Fill only part of the cavity because the foam expands after application. The correct fill level depends on the gap size and product instructions.
Avoid excessive application around door and window frames.
Leave the foam undisturbed for the recommended curing period.
Tack-free time, cutting time and full curing time are different. Follow the manufacturer’s guidance before trimming or finishing the foam.
Follow the product instructions for cleaning the gun and handling the can after use.
Use a compatible PU foam cleaner where specified. If the gun is to remain attached to the can between applications, follow the manufacturer’s storage and reuse instructions.
Application tip: For deep cavities, follow the technical data sheet regarding layered application and moisture requirements.

PU foam sealant is an expanding polyurethane material used to fill suitable gaps and cavities. It can help seal openings and provide thermal and acoustic insulation.
Gun-grade PU foam is supplied for use with a compatible dispensing gun. The gun helps control foam flow and the amount dispensed.
Gun-grade foam uses a dedicated dispensing gun, which provides greater control over application. Standard can foam typically uses a straw or adapter and is convenient for smaller or occasional jobs.
Yes. Use a compatible PU foam gun and follow the product instructions for attaching the can, adjusting flow and cleaning the equipment.
Suitable applications may include door and window frame gaps, construction cavities, selected service openings and other compatible building components.
Check the technical documentation before using foam on a particular substrate or in a specialised installation.
Yes. Expanding polyurethane foam increases in volume after dispensing. Leave sufficient space for expansion and avoid overfilling cavities.
PU foam can help reduce heat transfer and sound transmission through suitable gaps. The overall insulation performance depends on the foam, installation and surrounding construction.
It may be suitable for certain openings around cables and pipes. However, penetrations through fire-rated walls and floors require an appropriate tested firestop system.
Follow the gun and foam manufacturers’ instructions. Use a compatible PU foam cleaner where specified, and take care to avoid contact with uncured foam.
