Abstract
A construction profile is made of polymeric material and defines an inner cavity. The construction profile has an outer surface comprising unexposed side portions and exposed side portions. A stiffening profile is provided external of the construction profile and at an unexposed side portion thereof. The stiffening profile has a polymer material and a reenforcement material. The stiffening profile has a tensile (flexural) modulus in its length (L) direction of at least 5 Gpa according to EN2561 and the polymer material has a lambda value of maximum 2 W/mK.

A window profile made of polymeric material and defining an inner cavity, the window profile having an outer surface comprising unexposed side portions, defined between a pair of clamping brackets defining a drainage zone, and exposed side portions,
- a stiffening profile is provided external of said window profile in said drainage zone, the stiffening profile comprising two distinct longitudinal reinforcement edges extending parallel one to another and being connected by a web of polymeric material,
- wherein said stiffening profile comprises a polymer material and a reinforcement material, the reinforcement material only present in the two distinct longitudinal reinforcement edges is selected from the group of metal rods, metal wires, metal cables, glass fibres, aramid fibres, carbon fibres, continuous natural fibres and mixtures thereof, and locally embedded in the polymer web,
- the stiffening profile having a tensile (flexural) modulus in its length (L) direction of at least 5 GPa according to EN2561 and the polymer material having a lambda value of maximum 2 W/mK.
A stiffening add-on profile comprising at least two longitudinal reinforced edges extending parallel one to another and being connected by a web of a polymeric material, said edges each having a tensile modulus in the longitudinal direction of at least 5 GPa according to EN2561 and the polymeric material of the web having a lambda value of maximum 2 W/mK.
A kit in parts of:
- a construction profile window profile made of polymeric material and defining an inner cavity, the window profile having an outer surface comprising unexposed side portions and exposed side portions;
- a stiffening profile having a length (L) larger than its width (W), said width (W) being larger than its thickness (H), the stiffening profile having a tensile (flexural) modulus in the length (L) direction of at least 5 GPa according to EN2561 and the polymeric material of the web having a lambda value of maximum 2 W/mK,
- wherein said stiffening profile and window profile are designed such that the stiffening profile can be fixed at an unexposed side portion of said window profile, and
- the stiffening profile comprising two distinct longitudinal reinforcement edges extending parallel one to another and being connected by a web of polymeric material.
