Worked Solution & Example Answer:The main entrance door to a two storey dwelling house is a four-panel solid wooden door - Leaving Cert Construction Studies - Question 7 - 2012
Step 1
Draw a vertical section through a portion of the external wall, doorframe, door and first floor joists.
Answer
Begin your drawing with a vertical section at a scale of 1:5. Start from 400 mm below the top of the door, ensuring to include details of the external wall, doorframe, and door as well as the first floor joists. Mark the door height and ensure the section extends 500 mm above the first floor joists. Label key dimensions such as the overall height of the door and the thickness of the wall. Additionally, indicate the materials used in the construction, such as the timber frame, rendered concrete block, and any insulation used.
Step 2
Show clearly on your drawing the position of the vapour control layer to ensure an airtight structure.
Answer
On your vertical section drawing, clearly indicate the position of the vapour control layer. This layer should be positioned on the warm side of the insulation, to reduce the risk of condensation within the wall. It typically runs horizontally from the top framing to the bottom of the door assembly. Label this layer accordingly and use a different color or dashed lines to highlight it distinctly within your drawing.
