Internal doors can be customized in a number of ways, from the color and finish to the choice of door handles and metal inlays. Moreover, you can add acoustic seals to your doors to reduce noise to at least 29dB, and meet the new building regulations.
High quality bespoke internal doors can be ordered either as door leafs (that is, just the door) or as pre hung door sets where frames and architraves come with the door. If you decide to fit your home with fire doors, know these must meet certain fire door specifications concerning the glazing, the gasket system used and the fire glass thickness (usually 7—8mm). If you prefer, you can have your doors fitted with self closing hinges, but note that self closing fire doors are no longer mandatory. Make sure to get the original fire door certificate, though, to show to your building inspector.
Engineered versus solid wood doors
The former are more stable, less expensive and come in a wider array of finishes than solid wood products. The faces of engineered internal doors are real wood veneer, with a high density solid core and 25mm-28mm wood lippings on all 4 sides. The chipboard core is fire resistant, whereas the dovetailed solid lippings allow for on-site adjustments around door edges, top and bottom, if need be.
On the other hand, solid wood can be used for the beading around the panel; there are various beading designs and finishes since the panels on paneled doors can be either flat, or raised and fielded.
