Floor Spray Foam Insulation – Warm Floors, Lower Bills

Stop cold floors, moisture, and heat loss from below.
Spray foam floor insulation seals the underside of your home or building with a seamless, airtight thermal barrier — perfect for timber floors, concrete slabs, and underfloor heating.

We install closed cell spray foam for floors across Ireland, using NSAI-certified systems that support both thermal performance and moisture control.

Why Insulate Under Your Floor?

  • 🥶 Eliminate cold floors in winter

  • 💨 Block air leakage through floorboards or gaps

  • 🌧️ Prevent ground moisture and condensation

  • 🔇 Reduce footstep and impact noise

  • 💶 Cut heating costs and improve BER

Floor Insulation Applications

    • Suspended timber floors (foamed from below)

    • Concrete floors (foamed before screed or slab pour)

    • Underfloor heating systems

    • Crawlspaces and basements

    • Mobile homes, prefab units, and cold flooring areas

Air Tightness

Closed cell foam is ideal for floors due to its:

  • ✅ High compressive strength

  • ✅ Water resistance

  • ✅ Structural rigidity

  • ✅ High R-value per inch

Benefits of Spray Foam Floor Insulation

    • No sagging, gaps, or settling over time

    • Airtight and moisture-resistant

    • Helps meet airtightness standards for grants and BER upgrades

    • Can support floor structures in older buildings
