The hardwood edge laminations on Lamilite ladder stiles are far less prone to wear than the softwoods used in most timber ladder construction, and at the same time this hardwood is more resistant to the degrading effects of sun and rain. Since the hardwood edges are far less prone to wear and damage, Lamilite ladders produce far fewer wood splinters. Positioning the fibreglass reinforcing rod internally prevents any chance of fibreglass splinters. The development of the lamilite ladder was spurred by the rapidly diminishing resource of virgin growth Douglas Fir timber in the USA and Canada, and the consequent escalation of the price of that timber. Lamilite ladders are made from Beech, Ash and Pine from sustainable yield local forests.
Safety is the primary concern of every ladder user.
Lamilite ladder stiles have been designed in conjunction with the New Zealand Forest Research Institute at Rotorua. A significant feature of Lamilite stiles is the internal bonding of 6mm fibreglass rod which not only enhances the strength of the stiles but also provides a reliable 'safety net' should a stile ever be overstressed to the point of breakage. You say you have increased rigidity. A rigid ladder does not rack, twist or sway sideways. Well constructed timber ladders have demonstrated superior rigidity because of the self bracing nature of the rung to the style joint.
