How to Choose the Right Insulation
- Space available: If you have limited space, spray foam or retrofit roof insulation may be best.
- Wall type: Cavity walls allow cavity or spray foam insulation; solid walls need dry lining or external insulation.
- Home exterior: Want to keep your home’s original look? Consider internal dry lining.
- Disruption: External insulation and cavity fill usually cause less disruption inside your home.
- Budget and goals: Some options cost more but add value or improve soundproofing.
