Frequently Asked Questions
What does KFB1/NS mean?
KFB1 refers to Swartland's standard door frame profile for 813mm-wide doors. NS stands for "No Sill" — meaning the frame is supplied without a bottom threshold sill. This makes it suitable for interior doorways or sheltered exterior openings where a sill is not required.
What door size does the KFB1/NS fit?
The KFB1/NS is designed for doors measuring 813mm wide × 2032mm high with a 40mm door thickness — one of the most common standard door sizes used in South African residential construction.
Is this frame supplied assembled or in kit form?
It is supplied in kit form (unassembled). This significantly reduces the risk of damage during transit. The frame is pre-drilled and pre-dipped, making on-site assembly straightforward.
What tools do I need to assemble the frame?
No specialised tools are required. Standard carpentry tools are sufficient. Note that screws, adhesives, and braces are not included and must be sourced separately.
Does the frame come with draft seals?
Yes. The KFB1/NS is factory-fitted with composite rubber gaskets on all three sides of the frame, providing effective draft sealing and improved insulation once the door is installed.
Can I use this frame for an exterior door?
The sill-less design is best suited to interior doorways or sheltered exterior entrances. For exposed exterior applications, a frame with a sill and additional weather protection is recommended.
What timber is used in the frame?
The frame is constructed from solid laminated and finger-jointed wood — an engineered timber construction that resists warping and twisting, ensuring long-term dimensional stability.
Does the KFB1/NS come with a guarantee?
Yes. Swartland backs this frame with a 5-year guarantee, covering manufacturing defects under normal use conditions.
