Worked Solution & Example Answer:A non-load bearing timber stud partition separates two bedrooms on the first floor of a two storey dwelling house, as shown in the accompanying sketch - Leaving Cert Construction Studies - Question 5 - 2010
Step 1
To a scale of 1:5, draw a vertical section through the floor and stud partition.
Answer
Begin by drawing the ceiling as a horizontal line, labeling it as 'Plasterboard Ceiling'. Below that, represent the floor joists, ensuring they are drawn to scale (225 mm x 50 mm). Include the tongued and grooved floor beneath the joists.
Next, draw the stud partition extending downward from the ceiling. The stud should be drawn as a vertical line, labeled 'Stud Partition', with the typical size (120 mm x 20 mm) noted.
Add the flush panel door, labeled as 'Standard Flush Internal Door', at 1.5 meters above the finished floor level. Specify the typical door frame size (110 mm x 44 mm).
Finish the drawing by detailing the skirting boards at the bottom (typical size 120 mm x 20 mm) and the architrave around the door (typical size 70 mm x 20 mm). Label all parts clearly and ensure they are proportionate to the drawing scale.
Step 2
Show on your drawing one method that will help reduce the transmittance of sound through the stud partition.
Answer
One effective method to reduce sound transmittance is to fit rigid, semi-rigid, or flexible mineral wool between the studs of the partition. This material absorbs sound vibrations effectively. Additionally, the application of acoustic plasterboard to the stud partition will further enhance sound insulation. You may also consider sealing edges with acoustic tape to minimize any gaps that could allow sound to pass through. Finally, incorporating techniques like staggering joints between boards and fitting barrier mats around openings for pipes will provide extra soundproofing.
