Thermal Performance Test
Notes
The BT90 is designed as an energy efficient glass louvre system, it creates sustainability within the building envelope and also provides life safety by means of smoke relief / smoke ventilation.
The louvre systems sustainability works in conjunction with selected sensors: CO2 sensors / Internal & external temperature sensors / rain sensor / wind, speed & directional sensor.
The louvre systems smoke ventilation works in conjunction with the smoke detection system / sprinkler flow value system
Evidence
The product meets the requirements set out in the following documents, or relevant parts of cited standards within the documents:
BT90 louvre system has been designed for the purpose of
natural ventilation in buildings, it's design is to assist in architectural
sustainability requirements which comprises of a fully framed aluminium
assembly and blade holders which are thermally broken.
The system is manufactured and supplied in two options,
double glazed 32mm IGU or triple glazed 44mm IGU which is assisting towards the
H1 compliancy.
BT90 louvre system has been designed for the purpose of
smoke relief in buildings, it's design is to assist in the fire engineers
requirements for life safety. The system is operated by means of a manual
winder or 24v d/c extra low voltage field cabling.
Its usages are, but not limited to commercial / educational
/ industrial / residential sectors.
BT90 requirements are custom fabricated for each individual
project.
BT90 is a glazed operable unit with insulated glass IGU's
and requires support structures upon installation, the support structures are / but not limited to timber support framing / steel support framing / aluminium
support framing.
