Rockwool and British Gas install insulation in Hampton Court Palace, the Tower of London and Kensington Palace. Britain’s most iconic palaces have been getting a green makeover through a rigorous insulation project installed by British Gas and Rockwool. These three palaces after renovation will cut £130,000 from their gas-bills and reduce CO2 emissions by 850 tonnes over the lifetime of the insulation. Protecting the environment and making savings will further ensure that these palaces and their wonderful stories will be here for future generations to enjoy. The renovation is managed by Historic Royal Palaces and requires unique expertise for insulation installation in 500 years old buildings. Nearly 11,500 m2 of the three palaces will be covered by insulation. Around 7,000 rolls of insulation will be required for the project which will take around 1,900 hours to complete.
