How Fiberglass Insulation Is Installed

Fiberglass insulation comes in batts or rolls of varying thicknesses and lengths that must then be cut for installation. For the highest level of insulation, the fiberglass must be cut carefully so it can fit as tightly as possible around obstacles such as power sockets. This process is difficult for some installations and is time consuming. Although for quick insulation, fiberglass can be easily installed without professional assistance, the most benefits will accrue if a professional does the job,.

Fiberglass can irritate your throat and skin, so wear protective gear. Buy a two-strap mask rated for fiberglass insulation and wear a hat, gloves, a long-sleeve shirt and goggles to keep fibers out of your eyes.

Cost of Fiberglass vs. Spray Foam Insulation

On the whole, spray foam insulation costs two to three times as much as fiberglass insulation. Fiberglass insulation costs around $0.40 per square foot. Spray foam can be significantly more expensive, but can lead to bigger savings on heating and cooling costs. It costs around $3 per square foot, with a thickness of 3 inches.

Given the complexity of the installation process for spray foam insulation, the cost to install it are also significantly higher than fiberglass.

E-glass chopped strand mat-thin mat

Categories in the chopped strand mat, there is a kind of mat called: thin mat. As the name suggests, in fact, it is a thin mat. Which unit weight per 1M² is from 100 grams -200 grams, we referred to as mat.

In terms of the production process, the production operations are more complicated than other gram mat. First of all is to ensure uniformity of the chopped. Uniformity is very important. If the uniformity of the mat doesn’t good. The surface will easy to form holes and sparse surface. Moreover, when spray adhesive to the chopped, proportionality of emulsion and powder binder should be match good. Prevent too waste or influence the mat surface. In the production process, no matter which links appears small differences, there will be a obvious difference in the final products.

The use of chopped strand mat, mostly it is use to produce and manufacture frp hand lay-up model racks. Commonly known as: models mats, automotive interior Reinforcements materials, small crafts and so on.

Why trying FRP cross arms？

Why should you start using FRP cross arms in your next transmission project?
There are 6 reasons to explain this.

1. Asset management

FRP cross arms can be manufactured in relatively short order, providing quality structures in the large quantities utilities need.

The current lead time is as low as 3 weeks. This is in contrast to the over 6 month wait for industry-quality steel for electrical applications.

2. Cost savings

The largest expense in replacing wood or steel cross arms is the cost of time to send the crew to the installation site. Installation can be particularly expensive if the only way to access the site is by helicopter, due to rough terrain.

Installation costs are required to replace wooden cross arms every 25 to 40 years, depending on environmental conditions and the original quality of timber. Meanwhile, FRP cross arms provide the possibility to skip up to 2 of the replacement cycles required by wooden cross arms as they enjoy a life expectancy of over 75 years. In overall life cycle cost analysis, this represents a significant savings.

3. Environmentally safe

In a world where environmental concerns are becoming a key issue, the minimal environmental impact of FRPs are attractive.

FRP made with fiberglass chopped strand mat, cross arms are environmentally inert as there is no leaching of chemicals into the environment. Because of this, some environmental groups are embracing the use of FRP structures in environmentally-sensitive areas like bogs and wetlands.

In the case of disposal, nothing from the FRP cross arms will contaminate the environment and as such FRP cross arms can be recycled (preferred option) or placed in a general landfill.

4. Durability

FRP cross arms are also a very durable choice in warm, high humidity environments where treated wood does not last very long and steel corrodes very quickly.

FRP composite cross arms and also proved the viability of FRP cross arms in showing resistance to lightning strikes, bearing structural loads well, and long term durability.

5. Raptor & environmental protection

In some areas, raptor protection is a particular concern. When these birds land on energized steel transmission cross arms, their long wingspan can bridge over the distance between the conductor phases and metal cross arms, causing injuries and potentially loss of wildlife. When this happens, utilities have to pay significant penalties; it is also a public relations challenge.

With the electrically non-conductive nature of FRP cross arms, such accidents and issues are preventable.

6. Long term performance

Using new materials and components always raises questions about long term performance.

As mentioned above, accelerated aging tests performed by an independent laboratory confirmed that two component polyurethane composite cross arms have an expected life span of over 75 years. This is significantly better than the expected life span of wood cross arms and galvanized steel (with no additional corrosion intervention once the galvanized coating is gone), which is about 35 years in most urban environments.

Application of Fibre reinforced plastic FRP in Construction

Fibre reinforced plastic (FRP), sometimes referred to as composites, is an ideal material to use in construction, as it has a number of features making it cost effective and durable. These are two benefits that are very important to any building project.

Not only that, social and environment issues are changing the way people think about construction materials making FRP a more viable choice.

This is why companies within the construction industry should consider using FRP.

A study in the US forecasts a 4.7% annual increase in the demand for FRP composites. The study mentions that three-quarters of total demand would come from the automobile and construction industries – which points to the fact that a lot of businesses are already considering FRP as an alternative material to traditional materials, i.e. steel.

Two of the biggest key performance indicators on a construction project are cost effectiveness and durability. FRP falls under these categories for two reasons:

1. It has a low maintenance cost – FRP products are generally manufactured using a mixture of fibreglass and resin that make it more durable, thus reducing the costs over time as it requires very little maintenance; and fiberglass chopped strand mat!

2. Easy installation – compared to products such as steel, FRP is extremely easy to install. It’s also much lighter in weight which reduces the overall cost of a project.

There are many financial benefits of using FRP over alternatives such as concrete, steel and aluminium, with significantly lower maintenance costs being one of its biggest selling points.

In addition to the obvious fiscal advantages, environment and social issues will also highlight the business case for fibre reinforced plastics. The social aspect comes into play with large construction projects, such as bridges, that cause lengthy delays. Because FRP is easy to install, any delays can be minimised, thus freeing up traffic much sooner – a must on today’s busy roads.

Environmental concerns are playing an increasingly significant role in legislation. New laws and reimbursement schemes are persuading companies to lessen their carbon footprint. Business owners are demanding a greater scrutiny over the materials they use on construction projects in order to become greener. In the future, products with a longer service life, superior environmental performance and a reduction in maintenance costs, will be seen as highly favourable. These characteristics are what make FRP a highly sustainable product.

Binder Applicators System For Fiberglass Chopped Strand Mat

Powder Binder

The glass fibers are transferred from the conveyor belt of the forming section to another conveyor belt for the binder application. The forming belt will remain clean and dry everytime. Binding with powder is composed by 2(two) powder-binder-applicators, and a series of sprays of demineralized (distilled) water.

Both sides of the mat, the upper and the lower-one, are lightly sprayed with distilled water, that operation is necessary or a better adhesion of the binder. The special powder-applicators warrant an optimal distributing .

Between the two applicators a vibrator is applied providing that the powder is also passing to the lower side of the mat.

Binding with Emulsion

The curtain system used warrants a perfect distribution of the binder. The excess of binder will be recovered by a special sucking system.

This system pulls the air through the fiberglass chopped strand mat and a part of the binder will be taken off. By that mater the binder will be distributed uniformly and the excess of binder eliminated. 

Obviously the binder will be re-employed after special filtering which separates the air and the dirt.

The binder is stored in containers in the mixing room and conveyed at low pressure by a pipeline to a small tank near the mat-plant.

A special device maintain the level of the tank constant. Also the recovered binder will be conveyed to the tank. A pumping system conveys the binder from that tank to the curtain distribution system.
