Polyurethane (PU) window frames are a type of window framing material made from polyurethane—a polymer compound that can be molded into various shapes and structures. PU window frames offer several advantages and are gaining popularity in the construction and housing industries.
PU window frames are available in different finishes, colors, and styles, offering architects and homeowners a wide range of design options to complement the overall aesthetics of a building or home.
Polyurethane / PU Window Frame Benefits
Fiberglass polyurethane is 40% more stiffer than polyester, this allows for a stiffer profile or reduction in profile thickness by about 25% which reduces the profile weight and maintains the same stiffness as polymer profiles.
Fiberglass Window Frame Advantages
Increased Strength
Improved Transverse properties
Highest fiber volume
Higher specific strength and stiffness
Reduced wall thickness (weight savings)
Stronger profiles spanning greater distances
Excellent impact resistance (Polyester has poor impact resistance in comparison)
Excellent abrasion resistance
Easy fabrication
Excellent screw pull out strength (compared to traditional polyester pultrusion)
Much lower smoke generation than Polyester or Vinyl Ester
Excellent corrosion resistance
Aliphatic, light stable resins available
High Tg resin available – Tg>280 C
No Styrene emissions, no peroxides, NO VOCs
Pultruded Fiberglass Profile Features
Features | Description | Applications | Benefits |
Strong | Unit strength in tension & compression in approx
20x that of steel when these propoerties are combined on the basis of unit
density | Structural Process equipment support. Tank Supports,
Cooling tower ancillaries. Flooring supports. Trusses & Joints | Optional strength as desired. Exceptionally high impact
strength reduces damage potential |
Light weight | Density of pultruded components is about 20% of steel
and 60% of aluminium | Automative lead springs & bumpers. Prefabricated
walkways & Platforms. Bus components | Higher performance at less weight. Lower shipping
handling & installation costs. Less operational energy demand |
Corrosion Resistance | Unaffected by exposure of a great variety of corrosive
enviornment & chemicals | Chemical plant hand railings gratings, walkways &
bridges cable trays, pipe supports | Minimum maintenance costs. Long tern safety. Longer
Life |
Electrical Insulation | Provides strength and rigidity with dielectric
propoerties | Ladders, cable trays. Switch gear components. Mounting
braces and backboards | Lesser no. of components. Non-magnetic & safe.
Predictable insulation values for wide range of frequencies |
Termal Insulation | Pultruded Components have a low thermal conductivity,
1/250 of aluminium & 1/60 of steel | Bulk head frames. Walk in refrigerator door jams.
Window frames. Insulated roll up panel doors | Reduces installation thickness Elimates condensation
problems. Reduces energy operation requirements |
Consolidation | Many individual components can be combined into a
larger structure | Window latch supports. Roll up door | Reduced assembly cost, reduced inventory. Fewer parts
improve reliability |
Dimensional Stability | Pultruded components are highly resistant to warping
stretch/swelling over a wide range of temperature & stresses | Spring bumpers. Crossing gate arms, scrubber components | No permanent deformation under high stress. Close
tolerances |
Safety | The pultruded components are very strong & safe to
work with. They are microbes and insect proof. | Chemical & pharmaceutical industries | Many gratings suffer from the problem of microbes
etc.due to wet or unhygienic working conditions |
