Recessed downlights are a common feature in many homes, however they also represent a potential fire hazard, especially if buried in loft insulation. Numerous house fires have been caused by the ignition of combustibles in ceiling spaces caused by hot downlights being covered with insulation. 

The Astro LC Loft Cone are designed to provide a fire resistant solution and overcome thermal and vapour transmission into loft voids when installing recessed lights. The F-capped Approved Loft Cone maintains sufficient space around the fitting to allow continuous insulation to be laid directly over light fittings minimising overheating or fire risk.

The durable and lightweight cones are simply placed over the light fittings to allow the safe installation of loft insulation. The Loft Cones are certified F-capped in accordance with relevant industry standards having been tested to both BS EN 60598.1 and BS EN 60598.2.2. In addition the Loft Cones are Fire Resistance, Flammability and Airtightness tested and are certified IP6 Dust Tight.

We have technical representatives who provide assistance in the selection and specification of the products on this site and should be consulted for exact installation and product suitability. Ensure an early engagement with ourselves, designers, main contractor and specialist installers before any installation. Other trades and/or manufacturers may need to be consulted. For in-depth information, specification and technical advice please call our Head Office on Tel: +(0)1329 841416 or email


All interested parties, designer, specifier, main contractor and specialist installers should provide access to allow the fire stopping seals to be regularly inspected and maintained, as well as records kept of such maintenance at minimum periods of 12 months, as required by the Regulatory Reform Order, and repaired if necessary. Reference should be made to ASFP TGD 17 Code of Practice for the Installation and Inspection of Fire Stopping.


It is vital that those entrusted to design or install a fire stopping product have the necessary levels of competence to undertake the task professionally and thoroughly. The level of competency required will be commensurate with the expected complexity of the building. All designers must eliminate, reduce or control foreseeable risks that may arise during installation, construction or maintenance when preparing or modifying designs. Clients should ensure that the principal designer and principal contractor carry out their duties under CDM regulations. The ASFP foundation course in passive fire protection provides essential knowledge as part of demonstrating competency and understanding in this key fire protection specialism.
