Safety is of paramount importance
and it can be achieved with many different rooflight assemblies.With
an outstanding range of rooflights available and exceptional
technical expertise, Brett Martin Daylight Systems’
comprehensive service ensures a correctly designed and
specified non-fragile rooflight option for any building
that will also meet all other criteria such as light transmission,
type of light, aesthetics and budget. |

What do I need
to consider to specify a GRP rooflight with the correct
level of safety for my building?
|
|
| |
In terms of safety, the difference between
rooflights which achieve the same non-fragile classification, when
tested to the industry standard drop test for roofing
material ACR[M] 001:2000, is the margin of safety
that they provide, and the length of time they will remain
safe. |

| Safelight |
| Safelight provides the highest level of
safety and longevity, satisfying the 'HSE' preferred option
for long term non-fragility, with good light transmission
and unique 'Diamond' surface protection. It is suitable
for roofs that will require frequent and unlimited access
for a number of reasons, including maintenance, access
to monitoring equipment, ventilation ducts or other services,
and, in the case of stadia, lighting or TV cameras. Even
in situations where the roof has gantries and walkways,
if people are regularly on a roof, risks will inevitably
increase. In these instances, Safelight will provide the
optimum level of safety. |

| Trilite
Ultra |
Trilite Ultra offers substantially increased
safety margins over standard Trilite and is suitable for
projects that will require regular roof access after construction.
In these situations,Trilite Ultra will provide both
an increased margin of safety and length of time the rooflight
will remain safe. |

Trilite
|
|
|
| Correctly specified Trilite rooflights can generally achieve Class B and Class C non-fragility when new, and are available to meet industry recommendations for non-fragility for 25 years, as outlined in NARM Guidance Note 2004/I. These rooflights are most commonly used in simple, low cost structures where there is little or no roof access required after installation. |
