                      5.10
            Background
UL and ULC fire rated suspended and
gypsum ceiling designs require that
penetrations be protected.
Items such as recessed light fixtures,
HVAC diffusers & speaker high hats must
be protected with specified materials.
Historical protection methods include the
construction of a box using fire rated
ceiling tile or rated gypsum board.
 2006 International Building Code

712.4.1.2 Membrane penetrations.
 Penetrations that are part of a fire
 resistance-rated horizontal assembly shall
 comply with Section 712.4.1.1.1 or
 712.4.1.1.2. Where floor/ceiling
 assemblies are required to have a
 minimum 1-hour fire-resistance rating,
 recessed fixtures shall be installed such
 that the required fire resistance will not be
 reduced.
       Typical Detail, UL P202 - 1hr.

          Methods
Most UL suspended and gypsum fire
rated ceiling designs list Thermafiber
insulation board as a ceiling fixture
protection method.
Patented SafeLite covers are
fabricated from UL Labeled
Thermafiber board at 1 ¼” thick to
satisfy listing requirements.

Ceiling Attenuation Class (CAC)
 CAC is important and controls sound
 transmission and speech privacy
 between closed adjacent spaces.
 Common applications include:
 – Office spaces and corridors
 – Closed office, conference rooms
 – Mixed plan offices
 – Classrooms and music rooms
 – Healthcare exam rooms, doctor’s offices
  Example, Ceiling CAC Performance
    CAC, A measure for rating the performance of a ceiling system as a barrier
    to airborne sound transmission through a common plenum between
    adjacent closed spaces such as offices.

Conclusion: Just 2 uncovered light fixtures had a significant impact on the
acoustical performance of a ceiling.

The 4 db (decibel) CAC improvement shown with SafeLite is significant.
A 3 db change sounds as if the noise level was reduced by 50%.
This type of documented performance is critical for any sound proofing effort.
 A typical high performance acoustical ceiling with
     numerous penetrations (not uncommon for
  penetrations to make up 10 - 20% of the ceiling area.)




SafeLite covers restore ceiling sound blocking (CAC) performance.
Items such as recessed lights, speakers, HVAC diffusers, sprinkler
    heads etc. significantly compromise ceiling performance.
SafeLite Can Light Covers for
       Sound Blocking




Architect specified SafeLite covers to block sound from
lower level retail and restaurants to second floor office
            and third floor apartment space.
  A thermal ceiling scan reveals missing insulation.
Uninsulated recessed light fixtures represent areas of
    energy loss. SafeLite can reduce these losses.

               1 ¼” thick SafeLite light covers
                 provide an R Value of 5.25.

               Contractor Value
Contractors report averaging 1 or 2 heavy and awkward drywall or fragile
fire rated tile enclosures can be fabricated and installed per man hour.

SafeLite enclosures are installed on an average of 10 per man hour.

That translates to 80 SafeLite covers per 8 hour day Versus 8 to 16 for tile
or drywall enclosures. This provides an opportunity for BIG labor savings
(one contractor documented $10,000 savings on his first job using
SafeLite versus his previous field fabrication method).

At a rate of 2 drywall or tile covers per hour and a loaded labor rate of
$40/hr. would yield $20 labor cost to field fabricate and install plus the
material cost. Knotching necessary with these covers for hanger wires and
power cable is slow and can result in cover breakage especially on ceiling
tile enclosures.

it would only cost $4 in labor to install a SafeLite cover which easily slits to
accept hanger wire or power cable and is very durable minimizing call
backs.

Using SafeLite frees up skilled labor to perform other job functions.
Other SafeLite Advantages
Precise factory pre-fabricated kits typically
yield a better quality enclosure than field
cut and assembled methods.
SafeLite covers are more durable than
field constructed ceiling tile covers that
simply don’t hold up.
Peel and stick insulation pins keep
SafeLite in position on the light fixture.
Congested plenum space is not as critical
for installation access with lightweight,
flat SafeLite panels.
Ceiling Plenum Space
  At 1 ¼” thick SafeLite covers are
 easier to install in congested ceiling
 cavity areas then field constructed.
         SafeLite Users
Acoustical ceiling and drywall contractors
General contractors that self perform
Institutional facilities, especially
maintenance departments at hospitals and
retirement homes

 Without recessed light fixture protection, no
fire rating is achieved on either suspended or
drywall ceiling designs. Therefore significant
 potential liability exists for non compliance
          to code or UL design listings.
    SafeLite kits also offer enhanced ceiling
     acoustical and thermal performance.

SafeLite Installation Summary
   1) For existing ceiling applications, remove ceiling tile from both sides
   and ends of the light fixture to aid installation otherwise skip to step 2.

   2) Install the Peel N Stick “S” pins on a clean fixture top, approximately
   6” from each end of a 2’ X 4’ light fixture or one pin at about the center of
   a 2’ x 2’ fixture. Note: Keep pins away from the light ballast mounting
   location.

   3) Fold long side panels up so that facing paper meets facing.

   4) Slide SafeLite through ceiling grid and position over the fixture foil
   side up.

   5) Fold side panels down to create a 3 sided box.

   6) Position SafeLite square over the fixture aligning the end of the cover
   with the end of the fixture and carefully impale onto the “S” pin(s)
   tucking side panels inside the grid on both sides of the fixture.

   7) Carefully slit SafeLite to accommodate fixture support wires and
   power cable as necessary for cover installation.

   8) Carefully push insulation lock washer(s) down over “S” pin(s) and snip
   off excess to prevent injury.

   9) Position end caps against SafeLite, foil side out, flush with the cover top
   and secure to panel top center point using straight push pins at the center.
   Secure each cap panel end to the long side panel edge with additional
   straight pins.

   10) Cut ventilation slots as necessary to meet any specific UL listing and
   prevent fixture ballast from overheating.

   11) Replace any tiles that were removed during SafeLite installation.
                                                                     8/07
  SPI recommends first time users consult with the
project Architect and local Building Inspector prior to
              purchase and installation.
