1-Piece Nova Vita Installation Guide

Door jamb widths must be established before skirting is installed.

Example Door Jamb Calculation

For an 820mm wide door allow for:

• Door leaf width = 820mm
• Clearance between door and jamb = 3mm each side (6mm total)
• Door jamb thickness = 22mm each side (44mm total)
• Additional tolerance = 3mm each side (6mm total)

Total external door jamb clearance: 820 + 6 + 44 + 6 = 876mm.

Frame opening should be another 10mm (886mm) to allow for packing.

Mark this width centrally on the floor within the framed opening.

These marks become the skirting termination points and control final door jamb alignment.

Nova Vita skirting must be fixed directly to wall framing, not plasterboard.

Cut skirting to length to fit neatly between door opening termination points and internal and external corners. Use 45° mitre cuts at corners.

For straight joins, use splice joints. Butt joints are not acceptable.

Fixing Requirements

• Timber frame: nail or screw fix
• Steel frame: screw fix only

Fixing Centres

• Fix into every stud
• Maximum 600mm centres

Minimum Fixings Per Stud (by skirting width)

• Up to 90mm: 2 fixings
• 135–185mm: 3 fixings
• 235–285mm: 4 fixings

Fixings must include:

• One fixing positioned 20mm up from the base
• One fixing through the centre of the ribbed section

Install with 5mm packers under the skirting to allow for subframe movement.

IMPORTANT

• Nova Vita skirting must be fixed to framing, not plasterboard
• Do not use butt joints on straight runs
• Accurate set-out is critical for final door jamb alignment
• No noggins are required

Once skirting installation is complete, install plasterboard sheets down onto the top edge of the skirting.

Ensure:

• Tight, flush contact between plasterboard and skirting
• No visible gaps that may affect final finishing or shadow lines
• Sheets are straight, plumb, and flush

Fix plasterboard to framing as per the plasterboard manufacturer’s specifications.

Before fixing sheets, confirm final door jamb widths and heights align with the previously marked jamb positions.

Extend plasterboard sheets 50mm past the finished door opening on all sides and top. This overhang allows accurate trimming and a clean, flush finish once door jambs are installed.

Do not cut plasterboard back to frame or jamb lines at this stage.

Before setting, brush down the ribbed top section of the skirting to remove dust and debris.

Set all plasterboard joints, including the junction where plasterboard meets the Nova Vita skirting profile.

Jointing Requirements

• Use FibaFuse or paper joint tape only – non‑approved tape voids warranty
• Position tape centrally within the joint
• Bottom edge of tape must finish 5–10mm above the base of the ribbed section

Apply plaster set and accessories strictly in accordance with the plaster manufacturer’s instructions.

Recommended plaster products:

• USG Boral
• CSR

IMPORTANT: Crack Prevention

To minimise cracking at the skirting and plasterboard junction:

• Allow compound to fully dry between coats as per manufacturer specifications
• Typical drying times:
  • Approximately 24 hours in normal conditions
  • Up to 48 hours in cool conditions
• Do not rush coats

Refer to USG Boral plaster instructions for full compliance.

Install door jambs using the pre‑established opening widths and skirting termination points.

This ensures:

• Correct jamb fitment
• Flush alignment with Nova Vita skirting
• Consistent junctions between wall, skirting and opening

Ensure jambs are square, plumb and flush with finished wall surfaces.

IMPORTANT: Do not alter door opening widths after skirting installation. Skirting position controls final jamb alignment. Inaccurate set-out may affect:

• Door operation
• Visual alignment
• Final finish quality

Jamb Installation Notes

• Temporarily fix the two jamb components together before cutting to length to assist alignment
• Cut mitres to:
  • Top of stiles
  • Ends of head jamb
• Assemble mitres using PVA glue and nails or screws
• Trim plasterboard opening to suit jamb size, allowing 3mm clearance around the internal jamb rebate. A Makita DSD180 or similar plasterboard cutting tool is recommended for clean, accurate trimming
• Use packers on framing studs to install jambs plumb and square

Jamb Assembly Sequence

Nova Vita door jambs are a 2‑piece system, so ensure you:

• Install the rebate/grooved component first by sliding it into the plaster opening from the door side of the wall and fixing to the framing studs
• Install the second component from the other side of the wall where the tongue of this piece should slide into the groove of the first jamb component

Door Hardware

Once jamb installation is complete, doors are ready to hang.

Recommended hinges:

• Herline
• Fast Fix (offset knuckle)
• Concealed hinges – small thickness body to suit 22mm thick jamb, eg: CEAM door hinge (CEAM-BAC1230S)

A long‑lip striker is required to suit the wider rebate detail.
