1. Unit 1 Weather Resistance
Lesson 8

2. The purpose of weather resistance:
keeping occupants in an acceptable environment
ensuring thermal comfort of occupants
humidity levels
preventing damage to finishes and water staining.

3. Types and selection of waterproof and impervious materials, including:
double glazing
use of falls, weather seals and sealants, flashings and soffits.

4. The location of weather-resistant materials:
guttering
window and door openings
external walls
ventilation ducts
roof finishes and overhanging eaves.

7. Discuss together the following question:

8. Flashing

9. Where can you see flashing on this house?

11.  Ridge - The point of the roof  Verge - The sloping end of the roof   Eaves - Bottom of roof slope.   Fascia - Board that guttering is fitted
(you may only want to watch the first 5 mins of this)

12. How buildings achieve weather resistance
On your handout answer the questions below in as much detail as possible.
1) Identify five purposes of weather resistance.
2) Identify six applications of materials on a building that will improve that building’s weather resistance.
Teacher/tutor notes (PS 3):
Purposes: to keep occupants in an acceptable environment, thermal comfort of occupants, humidity levels, prevention of damage to finishes, prevention of water staining.
Materials: selection of waterproof and impervious materials, double glazing, use of falls, weather seals and sealants, flashings, soffits.
Location: guttering, window and door openings, external walls, ventilation ducts, roof finishes, overhanging eaves.
3) Identify six locations on a building where weather resistance can be achieved.
