FAQs about Single Internal Door Frames
Find answers to common questions about our internal door frame kits. If you have any more queries, don’t hesitate to contact our team for assistance.
What’s an internal door frame lining set?
A door lining set includes two vertical side linings (frame legs) and a horizontal head lining — the timber casing that lines the inside of a door opening and to which the door is hung.
A frame set, in comparison, is a more substantial structure that includes solid frame legs, a head frame, and sometimes a sill or threshold. It's typically used where the frame itself forms part of the structure
Do these frames come with door handles and hinges?
No, most of our frames are supplied without handles or hinges. The type and number of hinges required will depend on the door you choose.
Heavier doors, such as fire doors and composite doors, usually require stronger or additional hinges. Flush doors might also require specialised flat handles.
Direct Doors sells a variety of high-quality door fittings, including:
Various hinges: Heavier doors may require more hinges.
Door handles: Simple and elegant designs available.
What’s the difference between white-painted and white primed?
White primed means the frame has a base coat applied, so it’s ready for your chosen topcoat. White primer is great for adding brightness and evenness to topcoat colours.
White-painted means it already has its final white colour finish applied and is ready to use, with no further painting needed. These are commonly supplied as prefinished doors and frames.
Where do I find the specifications of each frame?
Each product page includes detailed specifications, including size, finish, and additional features such as:
Compatibility: Confirms whether your door can be installed on standard frame sizes.
Measurements: Includes frame length, widths, heights and breadth for easy project planning.
Construction: Information about the material, primer and finishing.
If you’re buying an unfinished frame, please pay careful attention to manufacturer-recommended products, as these are the only ones that ensure the quality and protection of your door. Other products may be incompatible, causing damage and affecting the performance of your frame.
