Why You Should Install a Natural Insulation

The Big Picture
Natural Insulations:

• Are more thermally efficient than mineral fibre
• Use less energy and emit less CO₂ in manufacture than mineral fibre (particularly Warmcel 100)
• Are safer to handle than mineral fibre
• Have the ability to absorb and desorb moisture without losing their efficiency
• Can store CO₂ during growth (hemp)
• Can help UK sheep farmers (Thermafleece and Black Mountain)
• Can be composted or incinerated for energy use at the end of their (long) life
• Warmcel 100 makes use of recycled newsprint
