SuperFoil vs traditional loft insulation
How multi-foil insulation compares with mineral wool rolls, the most common loft insulation in UK homes.
| SuperFoil multi-foil | Traditional mineral wool | |
|---|---|---|
| Thickness | A fraction of the thickness | Bulky; commonly recommended at around 270mm deep |
| Loft space | Keeps more headroom and usable space | Fills the joists and limits storage options |
| Moisture | Breathable; roof structure can breathe | Can trap moisture if wet or compressed |
| Dust and handling | No harmful dust; does not degrade | Loose fibres can irritate when disturbed |
| Summer heat | Reflects solar radiation away | Works by resisting heat flow |
