We continue this insulating series with a look at early-20th-century semi-detached houses with gas boilers. Four experts share their suggestions on what you can do to insulate your home on a variety of budgets: Paul Ciniglio, a refurbishment lead with the National Energy Foundation; Tim Pullen, an expert in sustainable building methods and energy efficiency; David Hilton, an expert in sustainable buildings and energy efficiency; and architect Paul Testa, who has carried out extensive energy efficiency improvements in his own home.
