Resistance Flashcards
Name 3 fire resistant materials
Concrete
Block work
Plasterboard
What is intumescent paint
Paint which swells when heated which ,Ames if fire resistant. (Slows down the transfer of heat)
Benefits of compartments in buildings
PREVENTS FIRE, AND HEAT FROM SPREADING FROM ITS ORIGINAL LOCATION
Maintains the building’s structural
Allows sufficient time to escape
Minimises destruction
Assists firefighters
Which materials can be used for thermal resistance
Timber
Lightweight screed
Aerated concrete blocks
Thermal insulation
Insulation against heat loss
Why are aerated concrete blocks good for good for thermal resistance
They have a lot of air in it. It is very insulating when it is trapped between solid layers
Where are plasterboards layers used for insulation
Inside insulating both solid walls
Types of thermal insulations
Sheep wool, rock mineral wool, foam
name a type of weather resistant materials used on roofs
flashings (made of lead)
Features of timber framed buildings
Plywood sheets (to provide strength and rigidity)
Lintel (used to direct rainwater away from the opening)
What is the purpose of a damp-proof membrane
Prevents transfer of moisture from the ground into the building
Does engineered timber require a lot of maintenance
No
Types of environmental load that can effect the structure of a building
Snow
Wind
Thermal
Rain s
What is a thermal load
Materials expand or contract with temperature change in which it can exert loads on a different element
