Abstract
A reinforcement apparatus mounts onto one or more extruded plastic window frame members of a window frame. The apparatus includes a reinforcement frame member comprising an extruded profile having a hollow interior and being formed of a fibre composite material. The composite reinforcement frame member is shaped to mate externally alongside the hollow profile of the respective window frame members to both extend the jamb and stiffen the plastic window frame member. In this manner, lower cost plastic window frames can be reinforced subsequent to the assembly of a window frame in a cost-effective manner.
