Ledged Doors – Updated Oak Grades Specifications

Here at Heritage, we have always had multiple oak grades available when purchasing an oak ledged door. By grading, we mean the quality and appearance of the oak used in the doors. Over time, we like to gather feedback from our customers and improve where we can. This, mixed with new production procedures and machines, means we have been able to edit our specifications to make them more specific and clear for our customers when purchasing

Our oak grades consist of 3 options –

  • Retail Rustic
  • Select Rustic
  • Prime
What are the differences?

Rustic oak grades are perfect for more traditional properties – such as old cottages and barn conversions. Prime is a great option for more modern properties or for customers who prefer a more plain look.

If you are a lover of natural character, rustic is the way to go!

None of our grades compromise on structure and are all made in the exact same way. Differences are purely cosmetic.

Regardless of grade chosen, all of our timber is PEFC Certified.

Oak Grades: Retail Rustic (also known as rustic or tavern grade)

One of the main key features of our rustic grade is the finger jointed ledges, you will not find these in any other grade. We use this machining method to minimise timber waste, and to also add an old style feel to the door. You may receive up to 4 finger joints per ledge, however if these are not for you, we recommend upgrading to our select rustic grade.

The image on the right shows a worst case scenario of the finger joints that can be present in a retail rustic graded door.
