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
To a scale of 1:5, draw a vertical section through a portion of the external wall, doorframe, door and first floor joists.
Answer
- Begin by setting up your drawing scale to 1:5.
- Draw the external wall as a vertical panel. Indicate that it is constructed of timber frame with a rendered concrete block outer leaf.
- Illustrate the four-panel solid wooden door positioned within the doorframe. Ensure to highlight the door dimensions for clarity.
- Detail the doorframe, including any lintels or additional structural support, and ensure the door is accurately represented within this context.
- Below the top of the door, mark a distance of 400 mm down the section; this will show the spatial relationship in the wall construction.
- Above the first floor joists, indicate a level at 500 mm and clearly label all significant dimensions, such as the height of the door and the surrounding structures.
Step 2
Show clearly on your drawing the position of the vapour control layer to ensure an airtight structure.
Answer
- On the section drawing, locate the appropriate position for the vapour control layer, which should ideally be situated on the warm side of the insulation within the wall assembly.
- Label the vapour control layer, ensuring it is distinct from other elements in the wall construction.
- Indicate how the vapour membrane intersects with construction elements, highlighting any overlapping or sealing details to illustrate an airtight setup.
- Describe how the vapour control layer integrates with adjacent components, such as the doorframe and surrounding wall, to depict its complete function in maintaining airtightness.
