Building Construction 1

Thermal Insulation Materials
The most common insulating materials on the market today are:

• Fiberglass
• Mineral wool
• Cellulose
• Polyurethane foam
• Expanded polystyrene (EPS)
• Extruded polystyrene

2- Moisture Insulation:

Moisture control consists of:

▪ Preventing water intrusion and condensation in areas of a building that
must remain dry.

▪ Limiting the areas of a building that are routinely wet because of their use
(e.g., bathrooms, spas, kitchens and janitorial closets) and drying them out
when they do get wet.

To be successful, moisture control does not require everything be kept
completely dry. Moisture control is adequate as long as vulnerable materials
are kept dry enough to avoid problems. That means the building must be
designed, constructed and operated so that vulnerable materials do not get wet.
It also means that when materials do get wet, the building needs to be managed
in such a way that the damp materials dry out quickly.

Many buildings require waterproofing. Waterproofing is especially for
bathrooms, kitchens, water tanks, swimming pools, roofs of houses and
every place where water is available for long periods

Types of waterproofing

Water insulation shall be divided according to the method followed in two
basic parts:
Positive insulation: a generally approved water insulation.
It depends on trying to prevent the water drop from entering the isolated body.
Passive insulation: Water insulation from the opposite side of water in the
isolated body. This method is used only when there is difficulty in applying
positive isolation.
