Thermahood – FAQs -Can I fit insulation over fire rated downlights?

It is now a requirement of Building Regulations that loft insulation must be continuous, meaning it is no longer acceptable to leave gaps in the insulation around downlights! The answer to this question depends on the type of downlight, some fire rated downlights can be covered directly with insulation and some cannot. The most comprehensive way of addressing this is to fit a fire rated downlight, a LED lamp with a Thermahood downlight cover and then fit loft insulation over this. Using this method you will have the benefit of a fire rated downlight, the energy consumption savings from LED lamps and the protection of Thermahood downlight covers!
