Tenmat FF120 Downlight Protection Cover

 

Airtightness & Thermal Loft Cover


Recessed halogen downlights are highly inefficient with typically 95-98% of the input energy being converted into heat and not light.

The halogen lamps can run very hot, up to 300 °C, therefore this type of lamp can generally not be covered with insulation otherwise it can overheat and cause a fire risk.

Where recessed halogen downlights are fitted into a ceiling under a loft space, the insulation is usually removed from around the light fixture. This then acts as a chimney allowing heated air to escape from the room into the loft space and out to atmosphere.

As the heated air is drawn into the loft space by the downlight then this is replaced in the room by cool air which is pulled through vents and gaps from the outside, this cools the room further.

To combat this TENMAT, as part of its continuing development of energy efficient solutions, has developed the FF120 Downlight Cover.

The Thermal Loft Cover has been developed to prevent the loss of heat from; and improve the air tightness of recessed halogen downlights. The Air Leakage improvement by fitting the Loft Cover can be seen on the green line in the adjacent graph (Red Line Downlight without cover).

The covers achieve this whilst adding maximum safety to the property via the addition of fire testing and ensuring that combustibles are kept away from the hot downlight.

The difference in a downlight with and without a loft cover can be seen via thermal image photography, in particular see how the unprotected downlight gets very hot and could be a possible point of ignition.
