Choosing the Right Loft Insulation
Selecting the right product largely depends on your specific insulation needs:
- General Insulation: For straightforward thermal insulation in the loft, classic rolls from Knauf or Rockwool may be apt.
- Acoustic Insulation: If you’re looking to minimise sound transmission, consider acoustic rolls or slabs, such as the Knauf Acoustic Roll or Isover Acoustic Partition Roll.
- Fire Resistance: For enhanced fire protection, consider specialty slabs like Rockwool’s RW series that offer added fire performance.
- Sustainability: If sustainability is a priority, Sheepwool or Thermafleece offer products that combine efficient insulation with eco-friendly materials.
