Alternative to Timber Windows


Blackthorn Timber is delighted introduce the launch of a new range of high-quality windows and doors in modern materials, each one with a specific customer requirement in mind. We call this our Blackthorn Choices range and it includes;

  • ‘Alternative to Timber’ flush casement windows and sliding sash windows – with detailing and sight-lines designed to replicate the look of old single-glazed timber windows, including full mechanical-jointing to both frame and sashes
  • ‘Alternative to Timber’ doors available in a wide range of period designs with the option of personalised designs as well
  • Solidor’s widely admired range of composite doors – solid timber construction wrapped in a long-lasting uPVC skin. Strength, stability, style in a single package!
  • Heritage aluminium windows, designed to replace steel ‘Crittal’ windows with a slim, energy-efficient and secure alternative.
  • Slender aluminium Bi-fold doors and Patio doors for a contemporary look with maximum glass
