Airtightness Spray Foam Solutions
Eliminate drafts, seal hidden air leaks, and boost your home’s energy rating with airtight spray foam insulation.
Our certified airtightness systems help meet BER requirements, SEAI grant criteria, and modern building regs — all while improving comfort and cutting heating bills.
We use NSAI-approved open or closed cell spray foam, depending on the structure and building type.
Why Airtightness Matters
Even small gaps and cracks around joists, rafters, pipework, or cables can leak heat — making insulation less effective and wasting energy.
Spray foam solves this by:
-
✅ Expanding to fill air gaps
-
✅ Creating a seamless air seal around structures
-
✅ Working in hard-to-reach places
-
✅ Reducing uncontrolled ventilation and drafts
Airtightness is now required in nearly all new builds and strongly recommended in retrofits.
