  • “When Cambium explained that timber windows are actually more heat efficient than PVC we were sold, especially since they did the traditional lead weight sash, they  look absolutely  great!”

  • “Cambium Joinery produced us some fantastic sliding sash windows to replicate those we had but double glazed to increase the heat efficiency of the house and reduce the drafts.  Our house is leasehold and therefore we had to follow the restrictions set out in the contract which was for timber only.  Our neighbours had replaced theirs with PVCU sash but they just didn’t look right.”
