11. COST?
• Material price…..?
• An installed rate …..?
• Other considerations…..?

12. Case Study:
Comparative analysis of the two options (Drywall and Blockwork)
WALL THICKNESS
65% reduced
dead load

14. Case Study:
Comparative analysis of the two options (Drywall and Blockwork)
SPEED
BLOCKWORK
DRYWALL
MEP INSTALLATIONS
MEP Installation at high level
and 2nd fix works to MEP are
finished after Blockwork
Completion. Suspended ceilings
also completed later.
MEP Installation at high
level can be Installed at
the beginning of the
Drywall sequence.
Suspended ceilings can
also occur earlier in the
programme
BLOCKWORK DRYWALL

Site Storage
and
Logistics
Light as 20kg/m2
gives up to 15%
structural savings
Less noise heard
from next door
Safe in a fire
Complete the
internals quicker
than with blockwork
Quick installation of
services through
stud cut-outs – no
channeling
Thinner walls
means more
room space to let
or sell
Many options for
many wall types
Straight, Curved,
Angled or High
Change of use?
Change the partition
easily with less
disruption
Less product on site
Less movements
Less damage
Lightweight
