What type of downlights and/or enclosures are suitable for installation into and through timber ceilings?
Only those products that are specifically certified by the manufacturer to be suitable for this use e.g. see FirebreakTM downlights. Note that if Arrowform retro-fit enclosures are required for enclosure of existing downlights installed into timber, then special instructions for the lining of the timber will apply e.g. the exposed timber in the cut-out and on the top of the ceiling must not be used as a part of the enclosure of the downlight. These instructions are not supplied standardly with Arrowform enclosures. Each case must be considered individually by an authorised technical consultant at Arrowform.
