The PlansXpress Trimmers to Flat Roof Openings Estimating Calculator is designed for use with PlansXpress to estimate the trimmers required around rooflights and skylights in flat roofs.
If you are estimating completely within EstimatorXpress (i.e. not using PlansXpress), trimmers are included in the PVCu Rooflight, Aluminium Rooflight or Velux Skylights Estimating Calculator, as appropriate.
If you have created your estimate based on a PlansXpress drawing, the data for the flat roof is imported into multiple separate EstimatorXpress Estimating Calculators. You will also need to review the Rectangular Flat Roof or Universal Flat Roof Estimating Calculator, and the rooflight or skylight Estimating Calculator.
The PlansXpress Trimmers to Flat Roof Openings Estimating Calculator estimates the following items:
- Trimmers parallel to joists
- Trimmers at right angle to joists
- Joists hangers
- Plus all labour associated with the above
This Estimating Calculator is linked to the specifications.
