CONCRETE ROOF DECK - a type of roofing system where the
roof structure is made from concrete. This type of roof deck is
known for its durability, fire resistance, and ability to support
heavy loads.
TYPES OF CONCRETE ROOF DECKS
1. STRUCTURAL CONCRETE DECKS
a. Cast-in-Place Concrete Decks - These decks are directly poured
on-site and become an integral part of the building’s structure.
They use normal weight concrete and are designed to carry
heavy loads.
b. Precast Concrete Panels / Decks - These are manufactured off-site
and then transported to the construction site. They are often
used for their speed of installation and consistent quality.
2. STRUCTURAL COMPOSITE CONCRETE DECKS – These decks are
made up of composite materials, specifically steel and concrete
which works together to support loads, acting as a single
component. It consists of a steel panel deck system overlaid with
either normal weight or lightweight structural concrete. The steel
panels are typically embossed to ensure a mechanical bond with the
concrete, allowing the two materials to act together to support
loads.
3. LIGHTWEIGHT INSULATING CONCRETE DECKS (LWIC) – These decks
are composite systems that combine lightweight concrete with
expanded polystyrene (EPS) insulation boards. The concrete mixture
typically includes Portland cement, water, and preformed foam,
which creates air bubbles within the material, making it lightweight
and thermally resistant. This type of deck provides good thermal
insulation and reduces the overall weight of the roof.
4. NON-STRUCTURAL INSULATING CONCRETE DECKS – These decks are
primarily used for insulation and roof fill rather than structural
support. They help in improving the thermal performance of the roof
system. The concrete used in this deck is mixed
with insulating properties.
ADVANTAGES OF CONCRETE ROOF DECKS
Concrete roof decks offer several advantages, making them a
popular choice for both commercial and residential buildings.
Here are some key benefits:
- Durability: Concrete is exceptionally durable and can
withstand harsh weather conditions, heavy loads, and
wear and tear over time
- Fire Resistance: Being a non-combustible material,
concrete provides excellent fire resistance, enhancing the
safety of the building
- Energy Efficiency: Concrete roofs have good thermal mass
properties, which help in regulating indoor temperatures,
leading to energy savings on heating and cooling
- Low Maintenance: Concrete roofs require minimal
maintenance compared to other roofing materials,
reducing long-term upkeep costs
- Design Flexibility: Concrete can be molded into various
shapes and designs, allowing for creative architectural
solutions
- Structural Strength: Concrete roofs can support additional
structures like rooftop gardens, decks, or even extra floors
TYPES OF WALLS
1. Stone Masonry Panels - are pre-fabricated units made from
natural or manufactured stone, designed to replicate the
appearance of traditional stone
masonry.
2. Pre-cast masonry panels - often referred to as precast
concrete panels, are prefabricated sections of concrete
that are cast in a controlled factory environment and then
transported to the construction site for installation.
3. Stick System – often referred to as a stick curtain wall, is a
type of curtain wall that is assembled piece by piece on-
site. This method involves installing vertical and horizontal
framing members, known as mullions and transoms,
respectively, which form the skeleton of the curtain wall.
The glass panels or other infill materials are then placed
between these mullions and secured with various
attachment methods
4. Curtain Walls – is an exterior covering of a building where
the outer walls are non-structural. This means they don’t
support the building’s weight but instead protect the
interior from the elements. Curtain walls are typically
made from lightweight materials like glass, aluminum, or
metal panels
5. Pressure equalized design for curtain walls - A pressure-
equalized curtain wall is designed to prevent water and air
infiltration by balancing the pressure between the exterior
and interior of the wall system
