Foam Guns

Our professional foam guns are designed to give you precise control when applying expanding foam for sealing, fixing and insulation tasks. Compared with basic straw nozzles, expanding foam guns deliver a more accurate bead of foam, reduced waste and cleaner results on site.

What are foam guns and how they improve expanding foam application

A foam gun is a reusable applicator that attaches to pressurised foam cartridges and allows you to apply expanding foam using a controlled trigger. Instead of relying on a basic disposable tube, the gun gives you fine control over flow rate and bead size, making it ideal for filling gaps, perimeter sealing and installation projects where accuracy matters.

Expanding foam guns for controlled, precise dispensing

Our expanding foam guns are built for trade use, offering smooth control when pulling the trigger so you can place material exactly where it’s needed. This ensures a neat, continuous bead that’s perfect for window and door reveals, frame protection, and sealing penetrations through walls and floors.

Foam gun features that enhance accuracy

• Adjustable flow control for different bead sizes and application needs.
• Ergonomic handle and balanced body for ease of use over long periods.
• Metal components for extra durability and long service life.

Benefits over standard expanding foam nozzles

Compared with standard straw-style nozzles, a foam gun allows you to:

• Apply foam more accurately with less waste.
• Work more easily in tight spaces and small gaps.
• Pause work and restart later without needing a new can in many cases.

Where foam guns are used in insulation and construction

Foam guns are widely used in insulation, joinery and general construction, particularly where a reliable spray-type application of foam is required. Typical uses include:

• Sealing junctions around window and door frames.
• Filling voids around service penetrations and pipework.
• Supporting perimeter sealing alongside other airtightness measures.

Choosing the right foam gun for your expanding foam

When choosing a foam gun, consider the types of foam you’ll be using, how often you’ll use it, and the environments you’re working in. Our range includes models suited to both regular trade work and lighter DIY projects, so you can find the product that matches your needs.

For frequent users, a robust model with metal body parts is the perfect choice, offering better durability and performance over many years of service.

Maintenance and cleaning to extend foam gun lifespan

Correct cleaning and maintenance are essential to keep your foam gun working properly. Using the correct cleaner will help prevent cured foam from blocking internal parts and ensure smooth operation each time you use it.
