THANK YOU
Need for Insulation in buildings Heat flows as per the capacity of the building materials in
units like floors, walls, roofs, doors, windows
Thermal insulation is retention of temp. with in the
buildings irrespective of the change in temp. outside the
building
It maintains the comfort conditions during summer and
winter.
Demand of heating in winter and cooling in summer is
considerably reduced.
The insulating materials should have adequate heat
insulation value per unit of thickness .
The provision of air space in materials for walls, roof,
ceiling etc. offers very good insulation where as the
presence of the moisture decreases this value.
Insulation materials Insulation is used to control temperature and sound in
buildings
All insulation products installed in U.S. buildings save 42
% of energy
Three main types of insulation:
Fiberglass Cellulose spray foam PU spray foam
Insulation Proesses
\
Glass and
Mineral Wool
Batting
Polyurethane, Polyisocyanurate,
Polystyrene, Cellulose
Board Insulation
Cellulose, Fiberglass
Blown-in Perlite, Vermiculite
Poured-In
Polyurethane, Polyicynene
Polyisocyanurate
Foamed-In
Forms of Insulation materials
Slab insulation: Blocks or board.
Blanket Insulation: Flexible fibrous rolls made
from mineral wool, cotton, animal hair, etc.
Bat insulating material: Blanket insulations
smaller in size and grater thickness which are also
spread on surface of the wall and ceiling.
Insulating Boards: Interior lining of walls ,
partition walls, structural insulation board
Reflective sheet material: Reflective sheet materials
have high reflective and low emissivity , thus
offering high heat resistance.
OVERDECK INSULATION
Applied over RCC followed by water proofing and
protective coating
Pre formed insulation boards
Should have adequate compressive
strength
Low water absorption
Resistance to high and low ambient temperature
Low thermal conductivity
Proper closed cell content
Proper Density
Complete thermal break with rigid insulation
sheathing
Exterior rigid insulation wall sheathing is used to provide a
complete thermal break at all wall framing.
The only uninsulated wall areas are the window and door
openings
Structural Insulated Panels (SIPs)
Factory-built insulated
wall assemblies
Ensure minimal thermal
bridging along with full
alignment of insulation
No gaps, voids or compression.
Structural Insulated Panels are whole wall panels composed of
insulated foam board glued to both an internal and external layer
of wood sheathing.
This assembly is manufactured with precut window openings and
chases
Insulated Concrete Form (ICF)
ICFs are blocks made from
extruded polystyrene insulation
designed to be assembled
“Lego” blocks into a compete
assembly.
Steel reinforcing rods are added and concrete is poured into the
voids, resulting in a very air-tight, well-insulated, and sturdy wall.
In addition to no thermal bridging, the insulation is inherently
aligned with the exterior and interior air barriers with no gaps,
voids or compression.
Measurement of U value
Thermal conductivity λ is the measure of heat flow (W/mK).
The R-value is a measure of resistance to heat flow through
a give thickness of material. (m2K/W)
A U value is a measure of heat loss in a building element
such as a wall, floor or roof.
U(element) = 1 / (Rso + Rsi + R1 + R2 ...)
where Rso is the fixed external resistance
where Rsi is the fixed internal resistance
R1… is the sum of all the resistances of the building
materials in the constructional element.
Three commonly used ASTM s for R value
ASTM C 177: Steady-State Heat Flux Measurements
and Thermal Transmission Properties by Means of the
Guarded-Hot-Plate Apparatus.
ASTM C 518: Steady-State Heat Flux Measurements
and Thermal Transmission Properties by Means of the
Heat Flow Meter Apparatus.
ASTM C 1363: Thermal Performance of Building
Assemblies by Means of a Calibrated Hot Box
