| Energy Efficiency | Can achieve considerable heat retention with draught-proofing. | Exceptional thermal properties, but often at the cost of looks. |
| Planning Permission | Usually not needed (unless in specific noted cases). | Frequently needed in Conservation Areas; restricted for Listed Buildings. |
