If you live in an area of protected beauty or a property of historical importance you may not be able to use normal roof windows. This is as local authorities will often have strict requirements to preserve the auesthetics of the local area.
Unlike normal windows, conservation roof windows feature a uniquely coloured external frame and integrated mullion bar. These are often required to meet the demands of building regulations in towns and villages across the UK.
Despite being designed specially for conservation areas, these roof windows still offer many of the same capabilities as normal roof windows. These include superb security features and incredible insulating capabilities.
