If you’re looking for an effective way to seal your walls, improve insulation, and keep pests out, expanding foam might be the perfect solution. Commonly used in commercial kitchens, food storage facilities, and other professional settings, expanding foam commonly known as; pour foam, foam fill, and foam insulation is an excellent choice for preventing rodents and insects from entering your walls while also improving energy efficiency.
Why Expanding Foam is Ideal for Pest Control
Expanding foam creates an airtight seal that blocks even the smallest entry points where pests like rats, mice, and cockroaches could squeeze through. Unlike traditional insulation materials, which can leave gaps, foam expands to fill every crevice, forming a solid barrier against unwanted intruders.
Used in Commercial Kitchens for a Reason
Many professional kitchens rely on expanding foam to seal gaps around pipes, walls, inaccessible areas and floors. Its ability to harden into a durable, impenetrable surface makes it a preferred choice in environments where cleanliness and pest prevention are crucial. By using it in your home, you can enjoy the same high-level protection trusted by the food industry.
Additional Benefits of Expanding Foam
1. Superior Insulation – Expanding foam provides excellent thermal insulation, helping to reduce energy costs and maintain a comfortable indoor temperature.
2. Moisture Resistance – Once cured, closed-cell expanding foam is resistant to water, reducing the risk of mould and dampness.
3. Soundproofing – Foam can help minimise noise transfer between rooms or from outside.
4. Long-Lasting Protection – Unlike other sealing methods, expanding foam does not shrink or degrade over time.
Where and How to Apply Expanding Foam
• Gaps Around Pipes and Wiring – Seal small openings where pests commonly enter.
• Wall Cavities – Fill spaces in walls to prevent rodents from nesting.
• Baseboards & Floor Gaps – Block hidden pathways used by pests.
• Outdoor Entry Points – Close gaps around vents, foundations, and utility lines.
Things to Consider
While expanding foam is an excellent solution, it should be applied correctly. Overfilling a space can lead to excessive expansion, potentially damaging walls. It’s also important to use a closed-cell variety for maximum durability and pest resistance.
