Worked Solution & Example Answer:The accompanying sketch shows a chalet with an external wooden cladding - Leaving Cert Construction Studies - Question 9 - 2008
Step 1
Choose a suitable wood for the external cladding and give two reasons for your choice.
Answer
A suitable wood for the external cladding is Cedar.
Reasons for Choice:
- Resistance to Decay: Cedar is ideal for outdoor use as it is highly resistant to decay, ensuring longevity for the cladding.
- Workability: It is easy to work with and glue together, facilitating the construction process.
Step 2
Recommend a suitable applied finish to help preserve the cladding and, using notes and neat freehand sketches, describe the steps involved in applying the finish.
Answer
Recommended Finish: A water-based finish is suitable for preserving the cladding.
Steps Involved in Applying the Finish:
- Preparation: Ensure the wood surface is clean and dry before beginning.
- Sanding: Lightly sand the surface and fill any imperfections with white spirit.
- Application of Finish: Apply the finish using a good quality brush, working in the direction of the grain.
- Coats: It is essential to apply three coats, allowing light sanding between each coat to ensure a smooth finish.
Step 3
Using notes and neat freehand sketches, show one design feature that helps protect the cladding from the effects of weather.
Answer
Design Feature: A projecting roof overhang helps protect the cladding from weather elements.
Explanation:
- The roof extends out over the front of the chalet, effectively shielding the cladding from rain and sunlight.
- This feature minimizes direct exposure to harsh weather, prolonging the life of the wood and maintaining its aesthetic appeal.
