I have just bought a bungalow with a dorma and the upstairs was freezing due to the storage cupboards. The cold was effecting the whole house and my bills! Safe to say after green horizon have been in and installed the new insulation it’s made a massive difference already. It’s no longer freezing upstairs and I’m not having to have the heating on all day to stay warm. Well worth the money for the fantastic product and very helpful and efficient workmen. Can’t wait to see how much my future bill will be cut down by. Thanks very much green horizon!
