No Insulation	~0.4	Solid brick wall, uninsulated cavity
Poor	~1.3	3-5cm old mineral wool
Fair	~2.0	3cm Polyurethane (PUR/PIR)
Moderate	~2.5	Post-insulated cavity wall (5-7cm)
Good	~4.5	10-12cm modern insulation (internal/external)
Excellent	~6.0+	>12cm high-performance insulation

Level	Rc-value	Examples
No Insulation	~0.2	Uninsulated roof boards
Poor	~1.3	Up to 5cm of old insulation material
Moderate	~2.5	5-10cm of modern insulation
Good	~4.0	10-15cm of modern insulation
