Therma-Flect General Purpose
Cavity Insulation Board EPS and PUR
Therma-Flect Wall Board EPS was originally developed
in 1995 to respond to the demands made by both Part L and Part J of the
building regulations/standards.
Therma-Flect Wall
Board EPS is formed from CFC and HCFC free expanded Polystyrene or high
performance Therma-Flect Wall Board PUR uses CFC Free Polyurethane, HCFC
free Polyurethane is also available upon request.
Therma-Flect Wall
Board EPS and PUR have a 50mm overlap to both bottom and right edges which
provide an impervious barrier to prevent the ingress of moisture and provides
a high resistance to thermal loss through the cavity.
Features
Fire Retardant – The
foil layer has a fire rating to Class 1
Therma-Flect Wall
Board EPS – The expanded polystyrene has a fire retardant additive to
prevent the spread of fire.
Therma-Flect Wall
Board PUR The Polyurethane has a TCEP Fire Retardant which also inhibits
the spread of fire.
Thermal Performance
– Total flexibility is achieved as the EPS Wall Board can be used where
space is available and PUR is used where space and performance is critical.
Site Exposure – Due
to the unique design of Therma-Flect Wall Board the Foil bubble sheet
forms an effective rain barrier.
