Technical Specification

These Heritage Black Internal Doors are a stylish complement to our internal French, Bi-folding (Roomfold Grande) and FrenchFold ranges, offering customers a Crittall Style Internal Panel door that matches our external Patio Ranges.

These doors have a solid core and feature a smooth deluxe primed black finish - meaning top-coating is only required should you wish to change the door's colour. The are also supplied with the standard lock block design, allowing you to use standard 65mm or 75mm latches, which really is a benefit against other similar, narrow stile, doors in the market where expensive specialist narrow backset locks. Finished in smooth black, these Heritage Black Internal Doors create that urban look at extremely competitive prices, for what is a solid core heavyweight door.

Conversely, the fire rated design is supplied with 18mm lippings, allowing for trimming of up to 12mm from any edge (for a maximum reduction of up to 24mm in height or width).
