This document discusses different types of insulation materials used in construction. It describes fiberglass, mineral wool, cellulose, polyurethane foam, polystyrene, and different flat and pitch roof insulation options. Key considerations for insulation materials include thermal conductivity, moisture sensitivity, durability, cost effectiveness, and environmental impact. The document provides details on the composition and properties of common insulation materials.

3. WHAT IS INSULATION ?
Building insulation materials are the building materials which form the thermal
envelope of a building or otherwise reduce heat transfer.
Insulation may be categorized by its composition (natural or synthetic materials), form
(batts, blankets, loose-fill, spray foam, and panels)

4. CONSIDERATION OF MATERIALS USED
• Thermal conductivity
• Moisture sensitiveness
• Compressive strength
• Durability
• Ease of insulation
• Cost effectiveness
• Flammability
• Environmental impact and sustainability
• Considerations regarding building and climate:
• The average climate conditions in the geographical area the building is located
• The temperature the building is used.

5. DIFFERENT TYPES OF INSULATING MATERIALS
FIBERGLASS
• Fiberglass is the most common insulation which is able to minimize heat transfer.
• Fiberglass is made out of finely woven silicon, glass powder and tiny shards of glass
are formed that’s why the danger of handling it
• An excellent non-flammable insulation material.
• A cheap insulation this is definitely the way to go, though installing it requires safety
precautions

7. MINERAL WOOL
Mineral wool actually refers to several different types of insulation.
• Glass wool which is fiberglass manufactured from recycled glass.
• Rock wool which is a type of insulation made from basalt.
• Slag wool which is produced from the slag from steel mills. The majority of mineral
wool is actually slag wool.
It is not combust able. when used in conjunction with other, more fire resistant forms of
insulation, mineral wool can definitely be an effective way of insulating large areas.

11. CELLULOSE
• Most eco-friendly forms of insulation. cellulose is made from recycled cardboard,
paper, and other similar materials and comes in loose form.
• Some recent studies on cellulose have shown that it might be an excellent product for
use in minimizing fire damage (because of the compactness of the material) .
• Type of insulation is relatively hard compared to, say, fiberglass. still, cellulose is a
cheap and effective means of insulating.

15. POLYURETHANE FOAM
• An excellent form of insulation insulating.
• Non-chlorofluorocarbon (CFC) gas
• Helps to decrease the amount of damage to
the ozone layer
• Relatively light weight
• Low density foams that can be sprayed into
areas that have no insulation
• Fire resistant

16. POLYSTYRENE
• Polystyrene is a waterproof thermoplastic foam which is an excellent sound and
temperature insulation material.
• It comes in two types, expanded (eps) and extruded (xeps) also known As styrofoam.
the two types differ in performance ratings and cost.
• Hexa bromo cyclodo decane

18. FLAT ROOF INSULATION
Warm flat roof
Reinforced Bitumen sheet
Foil laminated Polyethylene sheet

19. FLAT ROOF INSULATION
Inverted Warm flat roof

20. FLAT ROOF INSULATION
Cold flat roof

21. PITCH ROOF INSULATION
