Fire Retardant Treated Wood Products
Osmose FirePRO* fire retardant treated wood (FRTW) products are pressure
impregnated with an Osmose FirePRO interior high temperature fire retardant
chemical formulation based on proprietary Osmose technology.
Historically, fire retardants have depended upon phosphorus based compounds to achieve fire performance properties. While the unique Osmose FirePRO chemistry contains no phosphates, independent testing performed in accordance with industry standards has shown Osmose FirePRO FRTW products exhibit fire performance properties without compromising other critical engineering properties such as strength, durability, corrosivity, and hygroscopicity.
Application
Osmose FirePRO FRTW products are permitted for use in above ground interior
applications where the adopted building regulations permit the use
of wood products or fire retardant wood products such as: roof systems,
cladding, sheathing, joists etc.
It can also be used in other interior applications such as exhibition
stands. The specifier and/or end user is responsible to review the test
data on Osmose FirePRO FRTW products to determine if they are acceptable
for the intended end use.
The Treatment Process
Osmose FirePRO treating solution is applied to timber products in an
industrial controlled treatment process using vacuum pressure impregnation,
shown below.
Osmose FirePRO FRTW products must be Air or Kiln dried after treatment
to ensure the properties of Osmose FirePRO are maintained.
Osmose
FirePRO Standards
Osmose FirePRO FRTW products have been tested to BS EN 13501-1:2002 Fire
Classification of Construction Products and Building Elements. These
tests are commonly referred to as ‘reaction to fire tests’.
Reaction to fire tests are commonly called up in regulations in both
the building and transport sectors. The classifications of flammability
are A1, A2, B, C, D, E and F.
| Classification: (European) |
Equivalence to BS476 classification |
| A1 | Non combustible |
| A2 | Very limited combustibility |
| B | Class O |
| C | Class 1 |
| D | Class 3 |
The following species are currently approved:
-
Softwood Plywood
-
Far Eastern Plywood
-
Birch Plywood
-
Spruce
These commodities have achieved both B and C classifications using different loadings. Osmose FirePRO FRTW products can also be CE marked. Further materials are under going approval. Please ask for the updated list.
All FRTW products are treated by independently owned facilities
The specifier and/or end user is responsible for reviewing the test data
on Osmose FirePRO FRTW
products to determine if they are acceptable
for the intended end use.
