Fiberglass is a strong yet lightweight material made of glass fibers bound together with a plastic resin. It can be used to make various building products like roofing, doors, windows, insulation, and panels. Fiberglass products provide benefits like strength, corrosion resistance, insulation, and design flexibility at a lower cost than some other materials. They require relatively little maintenance over their long lifespan.

1. MATERIAL – FIBRE GLASS:
Fiberglass (or fibreglass) is a type of fiber-reinforced plastic where the reinforcement fiber is
specifically glass fiber. The glass fiber may be randomly arranged, flattened into a sheet (called a
chopped strand mat), or woven into a fabric. The plastic matrix may be a thermosetting plastic – most
often epoxy, polyester resin – orvinylester, or a thermoplastic.
Fiberglass is a composite structural material that consists of fiber reinforcements (typically glass) that
are bound together in a resin matrix. Fiberglass has a high strength-to-weight ratio, resists warping
and is resistant to environmental and chemical corrosion. It insulates from heat, cold and electricity,
withstands temperatures from -40 to 350 degrees Fahrenheit and can cost-efficiently be made into
complex shapes.
The glass fibers are made of various types of glass depending upon the fiberglass use. These glasses
all contain silica or silicate, with varying amounts of oxides of calcium, magnesium, and sometimes
boron. To be used in fiberglass, glass fibers have to be made with very low levels of defects.
Fiberglass is a strong lightweight material and is used for many products. Although it is not as strong
and stiff as composites based on carbon fiber, it is less brittle, and its raw materials are much cheaper.
Its bulk strength and weight are also better than many metals, and it can be more readily molded into
complex shapes. Applications of fiberglass include aircraft, boats, automobiles, bath tubs and
enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes,
cladding, casts,surfboards, and external door skins.
Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced
plastic (GFRP)
Why Choose Fiberglass over other materials:
Strong and long-lasting: Pound for Pound fiberglass is stronger than sheet metal. Fiberglass has a high
resistance to corrosion, it will not rust. Perfect for products used outside, in states near the ocean,
with the high salt content in the air. Fire-retardant resins can make your products stand up against
fire and will only char not burn up. Perfect when products will be around corrosive chemicals.
Design Freedom: There are very few restrictions with molding fiberglass, giving the engineer unlimited
possibilities. Get away from the old boxy looking products and design visually appealing ones that are
still as structurally strong and durable. Can take a multi-piece part and convert it into just one.
Appearance: Using fiberglass for product covers and enclosures definitely improves its
esthetics. Achieve any look and feel desired. Finishes give fiberglass components a high tech
appearance.
Cost Effectiveness: With steel being dependant on China’s steel prices, you will have stable prices with
fiberglass. Lower costs for maintenance and warranty work. A lighter and stronger product results in
lower costs for shipping and storage.
Special Characteristics: Fiberglass is non-conductive and radio frequency transparent. Perfect for
housing electronics without disturbing their performance and protect employees from hazards
inside. Fiberglass absorbs sound waves more than bounces off, thus giving it extremely good
acoustics, for lowering machinery volumes and achieving acceptable and/or required sound levels.
Unlike metal, plastic, and wood; fiberglass has the least expansion and contraction with heat, cold
and/or stress
The unique properties of fiberglass include:
• Coefficient of thermal expansion similar to glass
• Low thermal conductivity
• Dimensional stability

2. • High strength
• Rot resistant
• Chemically inert
• Easily paintable and re-paintable with minimum preparation
• Low environmental impact – made of readily available silica sand
• Future recyclable capability Over the past 10 years, fiberglass is used more and more in residential
and light commercial construction. It is becoming the preferred material for window frames and door
panels. According to Ducker Worldwide, fiberglass framed windows has been the fastest growing
segment of the residential window industry for the past several years.
APPLICATIONS IN HOUSING INDUSTRY:
Glass-reinforced plastics are used to produce house building components such as roofing laminate,
door surrounds, over-door canopies, window canopies and dormers, chimneys, coping systems, and
heads with keystones and sills. The material's reduced weight and easier handling, compared to wood
or metal, allows faster installation. Mass-produced fiberglass brick-effect panels can be used in the
construction of composite housing, and can include insulation to reduce heat loss.
a) FIBERGLASS REINFORCED PANELS:
Fiberglass reinforced panels are used on walls and ceilings, installing it directly over solid surfaces.
They provide a durable, scratch resistant surface, easy to clean panel and provides superior moisture
resistance. They are great products to be used in classrooms, restrooms and restaurants. Fiberglass
reinforced panels are made of strong polyester resin reinforced with fiberglass, providing a smooth
wall surface.
The final non-porous surface is becoming real popular for its ability to produce a mold and stain
resistant surface, protecting the wall from being scratched.
Fiberglass Reinforced Panels Advantages:
 Fiberglass reinforce panels provide a strong scratch resistant surface.
 FRP could be cleaned easily using regular detergents, high pressure washers, or even by using
steam.
 Fiberglass reinforced panel is a lightweight panel that is easy to install
 FRP could be installed either with glue or fasteners
 Maximum sanitation protection
 Improved chemical resistance
 FRP could be installed over any existing wall surface, by following some simple steps and no
high tech tools are required.
 High impact resistance from shattering and scratches
 Superior flexibility
 FRP could save you money when preferred over other building materials
 Fiberglass reinforced panels will allow the growth of mold or mildew and will not rust or
corrode
Fiberglass Reinforced Panels Applications:
FRP wall panels are ideal for kitchens, restrooms, dining rooms, offices, classrooms, hospital rooms,
hallways, cooling towers, recreational areas and other secondary spaces. One of the most important

3. applications of FRP panels is that they can be installed over new and existing drywall too, used to
repair damages surfaces.
Fiberglass Reinforced Panels related questions:
Q: Can Fiber Reinforced Panels be installed over most substrates?
A: Fiber reinforced panels could be installed almost on all substrates. However, the installation
method used will vary from one substrate to another.
Q: How to Install Fiberglass reinforced panels over Drywall?
A: Yes, FRP can be installed almost on all substrates by mechanical installation method. However if
the contractor wants to install Fiberglass reinforced panels using adhesives, it could be done, just need
to use solvent free adhesive only over porous surfaces such as concrete block, drywall, plywood or
plaster walls. When installing FRP over non-porous surfaces, such as wall tiles, using a solvent base
adhesive with rivets is recommended, In order to complete a better installation, remember to sand
the tiles so the FRP could adhere better.
Q: Does Fiberglass reinforced panels could be installed flat against the wall?
A: FRP panels are so flexible so it can be installed flat against the wall.
But remember as any building material, it will expand and contract according to environmental
conditions where it was installed.
Q: What tools are required to install FRP?
A: The installation of FRP could be done by using: a fine tooth saw blade, carbide drill bit, the
manufacturer’s recommended trowel, and a laminate roller that will be used to ensure maximum
adhesion between FRP and the surface where it is being installed.
Q: In what size does FRP is manufactured?
A: Fiberglass reinforced panels usually are manufactured in 4 foot by 8 foot sections and with some
architectural trims and/or moldings. For small applications and surfaces the FRP could be cut to exact
dimensions by using a power saw with a fine tooth, carbide tip blades or masonry blades. FRP Panels
in 0.090” thickness weigh about 12 ounces per square foot. A skid of 100 – 4x8’ panels weighs
approximately 2000 pounds each.
Q: What could be a possible solution and faster installation procedure?
A: Fiberglass reinforced panels could be supplied with pre-laminated sheets of plywood, EPS
insulation or drywall. By using this type of FRP, it will allow a faster installation and will produce a
smoother surface, because it eliminates the need for rivets. It is also recommended before installing
FRP to remove the packing of the panels, in the area where it will be installed. FRP ideally will absorb
the same environmental conditions of the place where the panels will be installed.
b) FIBRE GLASS DOORS:

4. Fiberglass doors provide several advantages over traditional wood and metal doors.Fiberglass doors
can be produced to look alike wood, and even a door expert will not differentiate between them. Built
tougher than regular doors, performing better under sudden climate changes and being able to be
customized for your specific needs. Some manufacturer's even specified that their products contain
no CFC'S, so you will get a product that will not harm the environment.
Even a new technology called 'Accugrain', introduced by Therma-Tru, duplicates the grain of real
wood. Although Therma-Tru can be considered the pioneer of this method, many such as Jeld-Wen,
Masonite and Plastpro have followed and used the same technique. Many builders are opting to use
fiberglass french doors as entry doors but also on garages and many other areas around the house.
However, keep in mind that these doors might crack if they are hit hard.
Benefits of Fiberglass Doors:
Fiberglass doors might present you with a higher up-front cost when compared with traditional wood
and metal doors, but in the long run, the benefits will surpass that initial investment. These doors will
rarely be scratched, peel or warp, and can resist different weather conditions performing better and
lasting longer than wood doors.
 Tougher than vinyl doors
 Available in a wide array of colors and styles
 Can be customized to your size selection
 Low-maintenance material
 Will not buckle
 Real wood like finishing
 Excellent protection against dents
 Can be painted easily
 Fiberglass doors are filled with insulating foam, offering at least five times the
insulating properties than wood doors

Be aware that although fiberglass doors are commonly used in many houses, they can also be warped.
This can be prevented by cleaning them regularly, protecting them from the sun and UV exposure and
look for doors that have been assembled using reinforced fiberglass panels, full-length stiles, and
water-resistant seals.
Fiberglass Door Costs and Installation:
As usual, the cost of a fiberglass door will vary depending on the finishes and installation procedure.
On average, these doors can cost around $500 for a regular basic door and can go as high as $2,500
depending on the product type.
On top of this regular sealing and staining will add some extra money for the property owner so be
aware of that maintenance cost. Some of the most important factors that can affect pricing are:
 Door size and shape
 Window style if any
 Paint and appearance
 Alternate finish options
 Weather protection or resistance
 Door hardware and detailing.
In addition to these costs, the material on which the door and frame will be installed can make the
price swing up almost as much as the door cost itself. In general, fiberglass doors can be installed using
the same cost as those billed for a wood door. For better pricing and more accuracy, it is
recommended to produce a field installation estimate, as measurements and opening dimension
needs to be precise and a complete assessment should be performed. You can always ask for
assistance at the American Window and Door Institute.
c) FIBRE GLASS ROOF:
People want new technology as per the changing time and many technologies have also emerged
which have fulfilled the expectations of people. Firstly it was only wood or metal roofing prevailing in
the market of construction of roofing but now there are many other methods such as asphalt roofing,
fiberglass roofing, steel roofing which have took its stand in constructing the roof. One of the most
fascinating and attractive method of roofing is fiberglass roofing method. This method is easy to install
and can be attested to roof. The roofing contractor helps the homeowners to concrete their decision
regarding this roofing method. Fiberglass roofing is new method to insulate in your roofing. The
fiberglass is structured from a slim glass fiber including silica which is blend together to make it strong.
There are many advantages of fiberglass roofing but there are also disadvantages which the
homeowner must keep into consideration before installing it into their roof.
Advantages:
1. The main phenomenon behind using fiberglass roofing is its versatile structures and different
colors and styles. Simple fiberglass roofing sheets are also available but homeowners like to

6. install it because of it upgraded look which consists of fascinating colors and designs on it
which gives a different look to your roof.
2. Fiberglass roofing is fire resistant in nature. It helps in protecting the house from wind, rainfall,
storm, etc. There are less possibility water drainage and leakage if maintained in a proper
manner.
3. Fiberglass roofing is light in weight as compared to other roofing methods. As metal roof and
wood roof are weighted but fiberglass roof is light in nature and with different and fascinating
styles on it.
4. It has longer life period in cool weathers so it is preferable to install it in the cooler region
places.
5. The materials which are used in preparing the fiberglass roof are less expensive and are easily
available in the market so its installation cost is less as compared to other roofing method, it
is easy to fix it and saves time of the roofing contractor installing it.
Disadvantages:
1. While installing fiberglass roofing the roofing contractor must nail is properly with proper
negligence so that it does not gets damaged because it is not metal or wood, it is made of
glass, so proper installation of fiberglass roofing is important because if not installed properly
than it can damage the home.
2. Maintenance of fiberglass roofing is not easy because it will need proper guidance and
appropriate materials to fill in the cracks which had occurred due to any unwanted weather.
The life of fiberglass roofing is not more than thirty years because they are made up of glass
elements.
3. Air exchange issues are noticed after installing fiberglass roofing in your home because
ventilation is important for every home and due to its glass structure it is not easily possible
of ventile region to exchange the spoiled air to the pure air.
4. As this roof comes in cutted and shaped sheets so manual cutting is also required for more
better and enhanced look of the roof where it is been installed.
d) FIBRE GLASS INSULATION:
Fiberglass insulation is significantly cheaper than spray foam insulation, although spray foam
insulation proves effective in extremely cold conditions. Used in roughly 85% of American homes,
fiberglass insulation is the most common form of home insulation. Meanwhile, spray foam insulation
has less of a market share but is increasing in popularity. Fiberglass insulation can also be installed by
homeowners, while spray foam requires professional insulation.
By trapping pockets of air, it keeps rooms warm in the winter and cool in the summer and thereby
serves as a convenient method to increase energy efficiency. Fiberglass is an attractive choice for
home insulation because it poses no fire hazard. According to some estimates, thermal insulation
(made from fiberglass and its alternatives) conserves 12 times as much energy as is lost in its
production, and it may reduce residential energy costs by up to 40%.
In homes, fiberglass insulation can be installed in various parts of the building envelope. It can be pink,
yellow, white or green, depending on its manufacturer, and has a spongy feel. Commonly found in
blanket form, called batts, it is available in bags containing standard pre-cut lengths and widths. Batts
are typically stapled into place. It also comes in bags as loose fill that can be blown into attic, wall and
floor cavities. Most fiberglass batts are manufactured with a paper or foil backing, which serve as a

7. vapor barrier, that faces the direction of warmth. When installed correctly, it creates a continuous
membrane that retards the passage of moisture and reduces the likelihood that fibrous particles will
enter the living space. It is important that the backing always faces the warm side of the structure in
which the insulation is installed.
e) FIBRE GLASS WINDOW:
Fiberglass framed windows and doors are high performance products that are more energy efficient,
longer lasting, stronger, more aesthetically appealing and environmentally friendlier than typical
wood, aluminum or vinyl windows.
Benefits of Fiberglass Windows:
Using fiberglass for window frame material is preferable to other window frame materials like wood,
aluminum and vinyl, because fiberglass:
• Performs well in humidity extremes and hot and cold environments.
• Has high condensation resistance which helps keep humidity within a proper range and limits
the growth of mold and mildew.
• Very low coefficient of thermal expansion and contraction (CTE). – Since fiberglass is mostly
glass, it expands and contracts at about the same rate as plate glass. – Aluminum expands and
contracts 3 times as much as fiberglass and vinyl moves over 7 times as much.
• Stress on seals, caulks and joints is minimized, contributing to higher efficiency windows.
• Tight seals maintain the resistance to air leakage and water penetration. – Seal failure can
increase the risk of water damage or mold and shorten the life of the product.
• About 3 times stronger than aluminum and 9 times stronger than vinyl windows. – Strength
decreases the limitation on glass size making large picture windows possible and energy
efficient.
• Unlike wood framed windows, fiberglass does not rot or warp.
• Does not require a “thermal break” found in most aluminum windows.
• Does not require the stiffeners that many vinyl frames need.
• Easier to install – Frames stay square and do not twist or warp, a common problem during the
installation of other types of windows.
• Practically maintenance free.
 Takes paint easily with excellent adhesion.
• Available in a large selection of colors.
MERITS AND DEMERITS:
The advantage of fibreglass is that it could be easily be moulded into any shape, has mechanical
strength that is so strong and stiff for its weight that it can out-perform most of the other materials.
Fibreglass last a long time, it can be coloured, shiny or dull. It is low maintenance, anti-magnetic, fire
resistant, good electrical insulator and weatherproof.
The disadvantages is that it needs to be re-gel coated about every five years and can result in
airborne fibres which may be an issue to asthma sufferers. Required Gaps around down lights and
electric boxes reduces the effectiveness, loses effectiveness if Insulation becomes wet or damp and
irritation during installation.
