Modern architectural trends continue to promote spacious, minimalistic interiors, with a focus on inconspicuous clean lines. So how do you achieve this level of fine detail when traditional door jambs require architraves to frame the jamb?
The answer is INVI Jamb®.
This unique frameless door jamb system wraps the plasterboard and can be plastered in during drywalling, to blend seamlessly with the wall and provide a flush finish around the door, eliminating the need for architraves.
Available with premium INVI Hardware® concealed hinges, INVI Jamb has four distinct profiles to suit your requirements:
- Classic split type jamb (INVI Jamb Classic Adjust – EZC) to allow for various wall thicknesses.
- Single rebated door jamb (INVI Jamb Single Rebate – SRC) to sit flush from the side of the door that houses the hinges.
- Inswing Door Frame (INVI Jamb Inswing – ISD) to achieve a seamless look in hallways and corridors.
- Double rebated door jamb (INVI Jamb Double Rebate – DRC) to allow two doors to be hung.
