Fiberglass insulation


 

Insulators are used to keep a balance in temperature within your homes and office spaces. They simply trap the air, keep your rooms warm in winter, and cool during the summer. There is a large range of different types of Insulation available nowadays. One highly popular type is Fiberglass Insulation. Let’s talk a little bit about the benefits and uses for Fiberglass batt Insulation.

Fiberglass insulation is very effective in terms of preserving the heat and sustaining a comfortable environment within your home or office. Installing Fiber glass insulation can help you reduce your energy usage instantly. Glass wool insulation has been used in multiple areas of life since the ancient era when Egyptians and Phoenicians used to use it, and Fiberglass came into the equation in 1932. The fiber glass material can differ in colour and can come in pink, white, yellow and green and you can install it anywhere in your home. They tend to have a spongy feel and are mostly found in Blanket form, known as Insulation Batts. Insulation Batts are useful as one can purchase it in various sizes and cut it to adjust it even further depending on the requirements of the project at hand.

Fiberglass

Why Choose Fiberglass Insulation for your Home?


 

There are many benefits to having Fiberglass batt insulation installed in your home. Firstly, they are relatively inexpensive, and anyone can afford them. Secondly, these insulators not only control and balance temperature but they also protect you from various hazards including fire, short circuits, and sound. Fiberglass is one of the ideal insulation material that one can choose for their home. Apart from being a common type of insulator, there are several reasons for installing fiberglass insulation 
 


  •  

Fiberglass insulation resists moisture as they do not hold and absorb water.


  •  

Fiberglass insulation is highly fire-resistant.


  •  

Fiberglass Insulation is a brilliant sound absorber. Perfect for noise control.


  •  

Fiberglass insulation is easily recyclable, and recycled Fiber glass wool can be used for many other purposes.


  •  

Fiberglass Batts are easy to install, and they can easily fit anywhere in your home.


 

Although the installation of Fiberglass Insulation has huge benefits it is worth mentioning that coming in contact with small particles of Fiberglass insulation can cause itchiness, irritation, and rashes. Make sure to wear gloves whenever dealing with this type of insulation.

Acoustic insulation


 

All high-quality insulation nowadays can provide far more for your home than just heat loss prevention. Fiberglass insulation is a great acoustic insulation as it acts as a sound barrier blocking out external unwanted noise.

Fireproofing Insulation


 

Almost all insulators come with fire protection from short circuits. If you are installing Fiberglass insulation in your homes and offices, then you can rest assured of their performance in different weather conditions. As they can preserve heat, they can also control extreme heat flow leading to a fire. There are many things responsible for fires starting within the home or office but with the use of proper fiberglass insulation, you are one step closer to a safer living environment.

Interstitial Condensation


 

This is the worst enemy of internal wall insulation in houses. This occurs due to damping and accumulation of moisture due to warm air inside your roofs and floors. Interstitial condensation is coming in two types according to the weather condition of the building, i.e. Cold Bridge condensation and warm front condensation. This can significantly corrode and decay the walls of your home and office. It happens when the warm and humid air is trapped. Fiberglass Insulation helps you prevent any kind of condensation build-up, and people can easily make sure that they protect from damping and the addition of moisture in the environment.

Moisture Resistant Insulating Material

Apart from fire protection and resistance from damping, these insulators also resist moisture in order to preserve the heat flow. Moisture resistance of the material is equally important as it helps to increase the life of your house as it stops any deterioration caused by flood, water, or moisture.

Conclusion on Fibreglass Insulation

The Fiberglass insulating materials are available in two forms and they are Pre-cut batts or rolls and blown in the loose fill. They are a more efficient form of Insulating materials compared to their alternatives that are cellulose and Spray Foam insulation. There is simply nothing better than installing fiberglass insulation even when you are renovating your home. Fibreglass insulations will help you make your buildings thermally efficient, allow you to save on your utility and energy costs. Also Fibreglass insulation will act as a sound barrier and provide fire and moisture resistance.
