- Plastering to sloping ceilings to attics
- Plastering to collar ceiling to attic
- Attic flooring
- Insulation to attic
The Worksheets calculate the following items:
- Timber noggings
- Plasterboard and skim
- Insulation
- Skirting boards
- Decoration
- Fixings

The Truss Roof Attic Interior Conversion Estimating Calculator is linked to the Specification.
NOTE:
- The Truss Roof Attic Interior Conversion Estimating Calculator assumes that the main structure, roof tiling and the ceiling underneath the attic has been estimated the Apex Truss Roof Estimating Calculator, ensuring that suitable roof timbers are selected.
- The Truss Roof Attic Interior Conversion Estimating Calculator should be used in conjunction with the Attic Shaped Wall Finishing Estimating Calculator which calculates the insulation, plastering and decoration to the shaped (gable) attic walls.
- If you are converting a truss roof, you may need to consider additional timbers in the sundries section of the Apex Truss Roof Estimating Calculator. The floor may also need strengthening which you can estimate using the Suspended Floor Estimating Calculator.
- If you are estimating a loft conversion in an existing property, any additional plastering of the ceiling under the attic should be treated separately using the Plastering Estimating Calculators.
- Particular attention should also be applied to the types of insulation and plasterboard used in each section.
