What is bead cavity wall insulation?

Bead insulation is blown into the cavity between your walls using a specialist gun. Incredibly thermally efficient, they trap heat in your home to keep it warmer during cold weather. The beads won’t decay, they’re water repellent and they require fewer bore holes to install than wool or foam. To see if you’re eligible for a grant to cover the cost of installation, speak to the specialists at Eco Subs Ltd today.
