Cavity Wall Insulation

Cavity Wall Insulation

Cavity wall insulation is a simple yet highly effective way to reduce heat loss in your home. Most homes built after the 1980s have a gap—or "cavity"—between the inner and outer walls. By filling this space with insulation material, you can significantly improve your home's energy efficiency.

At CosyFill, we offer professional cavity wall insulation services using high-performance, eco-friendly materials. The Sustainable Energy Authority of Ireland (SEAI) offers grants of up to €1,700 for cavity wall insulation under the Better Energy Homes Scheme. The best part? Our team handles the entire grant application process for you—from paperwork to approval—making it stress-free and easy.

Benefits of cavity wall insulation include:

  • Up to 35% reduction in heat loss

  • Lower energy bills by €300–€600 per year

  • A warmer, more comfortable home

  • Reduced carbon footprint

Don’t wait for winter to bite—insulate now and save long-term.
