Locking windows & pvcu window locks

Rule number one: if your window lock is failing, please don’t force it. Pvcu windows just like other window frame materials expand and contract with heat and cold, meaning that locks can go out of alignment.

Forcing a lock could cause the key to snap in the lock, break the lock or see the latch cause costly damage to the frame.    

There are wide range of window styles and window locks can be positioned in a variety of places. On a casement window, the window opens outwards and may be hinged and secured either at the side (side hung /side opener) or with hinges at the top and handle on the bottom (top hung /top opener). Tilt and turn windows however always open inwards, with the option of opening fully or just tilting inwards from the top for ventilation purposes.

Types of double glazed window locks

Window locks positioned in different places can be prone to different stresses and over the years, double glazing and frame systems have been developed to make things easier to use, adjust and fix and generally more robust all round.

Common pvcu window lock types include:         

  • Replacement Inline lock rods pvcu window locking mechanisms
  • Versatile replacement Espag window mechanisms  
  • Replacement Gearbox and Shootbolt mechanisms – failure is usually with the gearbox rather than the rods.
