Gutter Foam — Simple, Effective Gutter Protection
What is Gutter Foam?
Gutter foam is a lightweight, open-cell polyurethane insert designed to sit neatly inside your guttering. It allows rainwater to flow freely while stopping leaves, twigs, and other debris from causing blockages.
Our Open-cell Polyurethane Gutter Foam is flexible and easy to install — providing reliable protection without changing the appearance of your roofline.
Key Benefits
Prevents blockages: Keeps leaves, dirt and debris from entering gutters and downpipes.
Ensures water flow: Open-cell structure allows rainwater to pass through freely.
Lightweight and flexible: Easily compressed for a snug fit in different gutter profiles.
Easy to install: No tools or fixings required — simply cut and place into your existing gutter.
Low maintenance: Reduces the need for regular gutter cleaning.
Discreet and durable: Sits inside the gutter, hidden from view, and made from long-lasting polyurethane foam.
Protects against water damage: Helps prevent overflow that can damage fascia boards, eaves and foundations.
Typical Uses
Residential homes and rental properties
Garages, carports, and sheds
Buildings surrounded by trees or vegetation
Gutters that are difficult to access safely
Seasonal or temporary gutter protection
How It Works
The foam acts as a filter — water passes through the open cells into the gutter, while larger debris remains on top to dry out or blow away. This keeps gutters clear and flowing without frequent cleaning or the risk of overflow.
Maintenance
Inspect twice a year: Especially after autumn and major storms.
Remove surface debris: Brush or hose off any buildup that settles on top.
Rinse when required: If sediment builds up, lift the foam out and rinse with a garden hose.
Replace when needed: Expected lifespan is typically 3–5 years, depending on exposure and environment.

Steps
Clean the gutter: Remove all leaves, dirt and debris to start with a clear channel.
Measure: Measure each section of gutter and cut foam to length.
Fit: Place the foam into the gutter so it sits snugly against the sides without being compressed too tightly.
Trim around outlets: Cut small sections to allow easy water flow into downpipes.
Test: Pour water through to confirm proper flow and fit.
No clips, fixings or drilling required.
