Wall Insulation

There are several ways to make a home or commercial structure comfortable considering its inner temperature. The most common and reliable way is to insulate it. Benefits of home insulation or insulated structure is a well-known phenomenon. Different areas of structures have varied significance. Insulating these areas with the right R-value with professional help is necessary. It can favour the thermal conditions of these structures for years. 

What Do You Need To Know About Wall Insulation?

Warm air easily seeps through the walls in any structure. In old homes that have solid and uninsulated walls, it becomes easier for warm air to get through. Wall insulation is the insertion of insulating material between the layers of the wall. Creating a thermal envelope in your home is the important function of wall insulation. 

According to studies the heat loss through the walls go up to 10-20% during winters while the percentage gained during summers goes up to 15-25%, which is an increase. 

A well-insulated home prevents the escaping of heat and also gaining through walls. Residential wall insulation creates a bigger difference in regulating your home temperature. Like any insulation and its purpose, wall insulation provides quality resistance to heat flow. Ideally, this is known to work as efficiently as a heating system or air conditioners. Wall insulation reduces the high energy bills by making the thermal condition of your home even in all the spaces. 

Exterior and Interior Wall Insulation

Apparently, up to 25% of heat is known to escape through walls. Exterior wall insulation is thermal insulation that balances the temperature of the residential or commercial structure. Insulated walls are a cost-effective way to increase comfort in your home and commercial structures.  Insulating your interior wall reduces the transfer of heat flow from one space of the home to another. Absence of interior wall insulation can allow outside air to enter your home causing an imbalance in your home temperature. Ideally, interior wall insulation is installed during new construction but adding insulation to existing walls is also possible which does not require the drywall to be torn off. 

Benefits of Exterior and Interior Wall Insulation

Exterior Wall Insulation Interior Wall Insulation
It acts as a water-absorbing agent creating a barrier for water accumulation and protects your brickwork from dampness or dirt. It is similar to exterior wall insulation and reduces heat flow from one space to another in your home.
Exterior wall insulation increases energy efficiency and along with its profitability. It is energy-saving as it reduces heat transfer and prevents unnecessary utility costs of even unused rooms or spaces of your home.
Exterior wall insulation reduces internal and external noises. Its sound-proof quality makes it more notable. Party walls or living spaces are benefitted with not only thermal control but also fire resistance.
It is cost-effective and saves your energy bills which can go high.  Sound-proof quality is another plus for you with the interior wall insulation.

Closed-Cell Spray foam 6.1 to 7 per inch Acts a vapour barrier and eliminates air infiltration 
What R-Value Do You Need For Wall Insulation?

As the R-Value of insulation becomes the determining factor of its ability, the value has to be higher for better performance. It depends on your living conditions or location. It also depends on which part of your home you want to be insulated. There are different levels of insulation for different climates as well as corners and spaces of your home. 

Typically, R-13 to R-23 is recommended for exterior walls. The regular R-Value ranges from R-12 to R-15 depending on the type of insulation material and its frame size. The minimum requirement for a cavity is 4’’ deep for it to be effective enough. Know more about R-value and wall insulation installation at Celluloseman. 

Does Wall Insulation Help Sound-Proofing?

Wall insulation is considered to be very effective for soundproofing. If your home has unnecessary noises loudly echoing around, then it is time to get your insulation done. It simply means that your structure lacks the required insulation. Wall insulation is an excellent way of resisting external noise disturbance. Most of the modern homes come with properly insulated walls. But some old homes which need a renovation will also need a thorough check on walls. Some wall insulations like cellulose, fiberglass and foam prevent and reduce noise not only from the outside but within the home or other structure too. Generally, loose fiber acts as a sound-absorbing agent which is the determining factor for sound-proofing. Insulations like fiberglass and cellulose are ideal for walls, ceilings and floors. Loose-fill cellulose and fiberglass insulation are considered as the best types for effective sound-proofing. 

Benefits of Wall Insulation

Improves Thermal Conditions

Like any insulation, wall insulation controls and manages the thermal conditions of your home by keeping it warm in a cold climate and cold during warmer days.

Fire Resistant

The mineral wool used for wall insulation prevents your home from fire accidents by controlling the spreading of fire and reducing the amount of damage in return.

Saves Your Energy Bills

On average, up to 40% of heat is released through walls. Homeowners experience a drastic change after getting their walls insulated. Exterior wall insulation saves a higher per cent of homeowners’ pockets by reducing their heating bills annually.

Sound Absorbant 

Wall insulation prevents noise from one room to another along with the outside noise. Insulating your walls, ceilings and floors can be highly effective for soundproofing. Mineral wool is considered the best of types for this purpose.

Increases Life Span & Value Of Your Property

Insulating walls of your property does not only balances the thermal condition but also protects it from extreme weather conditions which can affect the lifespan. Insulated homes or properties are preferably high in the saleability because of high energy performance.

Is blown in better for wall insulation?

Yes, blown-in is better for wall insulation because it is environment-friendly with materials like cellulose and fiberglass. It requires a professional hand as it involves drilling into spaces with electrical wiring or pipes, even though blowing in at attics can be done by yourself.

Can I insulate interior wall without removing drywall?

As interior wall insulation reduces the heat transfer from within the spaces of your home, it saves you from high-cost bills due to heating system or air conditioners. 

Can we insulation exterior walls without removing drywall? 

Yes, we can, we would inject insulation in between cavities. We have to drill holes and use a wooden plug to cover the drilled areas after we filled that particular area. The best time to do injection is before the drywall is up so we can clearly see the cavity.
