If your house has old or poorly fitted fibreglass insulation on the loft floor, then you have outdated building technology in the form of a Cold Roof System.
A Cold Roof allows air to enter your property from the outside whilst heat from the living space rises into the loft and escapes through the roof.
Good insulation in the home is essential in creating a healthy environment with controlled expenditure on heating costs.
When the roof space is insulated between the rafters you have the peace of mind that cold air from the outside will not intrude on your warm home.
