Downlight covers provide a barrier between the downlight and the inside of the roof. This protects against ceiling fires by preventing light-generated heat from igniting ceiling dust and debris. Halogen downlights compromise the effectiveness of ceiling insulation because installers need to place insulation at considerable distances from each halogen globe. With a downlight cover, installers can place insulation right up against the guard, sealing any gaps and greatly improving efficiency. It does not take long to notice the difference this makes when trying to keep a room warm or cool. Halogen lights can also push ceiling debris, dust, allergens, pollen, and insects into a room. The seal the cover creates prevents this from happing and improves air quality inside the home.
Enforced by law in some areas, downlight covers have become a non-negotiable safety feature in many modern building regulations. If you have halogen downlights in your ceiling without the appropriate protection, resolve this by selecting the best choice of covers from the eBay selection.
