Show hintHide hint
Consider the environmental conditions around the structure.
3Question 3.
What does permeability refer to in roofing systems?
- A measure of strength
- Degree of openness

4Question 4.
True or False: High permeability will reduce internal pressures during strong winds.
- True
- False
Show hintHide hint

Question 5.
A roofing system is designed with 30% permeability. Calculate how this would affect its uplift under a wind speed of 100 km/h, assuming the design codes consider this value critical.
Show hintHide hint
Look for standard equations related to wind uplift and incorporate the permeability factor.
Question 6.
Propose recommendations for a building project located in a windy area that intends to use a highly permeable roofing material.
Show hintHide hint
Think about both material selection and structural physics.
