Sound Proof Insulation

We expect our home to be a haven where we can rest and relax after a hard day. However, our home can also be a center of activity where all kinds of noises mix to form a cacophony of sound that can disturb even the soundest of sleepers. Some people don’t really think they need sound proof insulation for their homes until they start being bothered by all the noise coming in. You’d be surprised how many people don’t really consider their homes as a noisy place.

Think about it. Preparing food in the kitchen, people eating in the dining room, people watching TV or listening to the stereo in the living room, and all the other appliances in your home like the dishwasher, washing machine, vacuum cleaner, etc. – all of these create sound and noise that can be an annoying distraction. What’s more, sounds from the outside like cars passing by on the street, pedestrians on the sidewalk, a construction crew working at the next block, and other daily occurrences can all add to the bothersome distraction.

You don’t have to put up with all the noise, however. You can have sound proof insulation installed in your home to combat all those sounds, or if you have the skills and tools, you can also do it yourself. There are several different ways to insulate your home against sound, but they all have some pros and cons to them.

For example, the common materials that people use to insulate their homes against heat or cold, like glasswool (also called fiberglass), can work very well when used as sound proof insulation. They just need to be installed meticulously to perform to their fullest capabilities. Glasswool insulation can help reduce noise that’s coming through the walls, but the material will need to be painstakingly cut and fitted around the pipes, wiring, and other elements inside and in between the walls. Furthermore, all holes and cracks in the walls will need to be sealed to help reduce noise as well.

Generally, fiberglass insulation is not really recognized as an excellent sound insulator, although they do make great insulating material for heat or cold. However, modern technology has allowed manufacturers to create high density glasswool insulation that can offer extraordinary performance for both acoustic and energy purposes. There are glasswool products nowadays that are rated up to R-2.7 for wall installations and up to R-6.0 for ceiling installations.

Installing glasswool or fiberglass insulation alone will not provide high level soundproofing, of course. You will also need to take additional steps such as using solid core wooden doors, tightening up the spaces between the wall and the windows, installing high quality storm windows, and even installing thick carpets. If you install storm windows, take note that the wider the space between the storm window and the primary window, the better it blocks sound from coming in. Also, if you have a wall that faces a busy street, adding another layer or two of drywall to that wall will significantly improve noise reduction.

Great Way to Protect your Home

Insulating your roof is one of the most important energy-saving projects you can complete in your home. Nevertheless, when saving energy, you are also helping to reduce pollution. Therefore, reducing the amount of energy we consume can have a big effect on environment. In addition, you can gather information if you want to know how a roof insulation can help you save money. If the roof is not insulated, there are high chances that it will weakened over the time. This is bound to happen eventually and you may have to go for an entire roofing overhaul project if the roof is seriously damage at different crucial spots. However, with roof insulation, this can be prevented. Though roof insulation will cost you in the beginning, yet that cost is nothing when compared to that of a complete overall that may cause serious financial troubles for you unless you have a lot of money in your account. You may consult to roof insulation expert to choose roof insulation with proper insulation batts and rolls since it is simply use to cover the ceiling joists that roll over them.

Whether it is hot air in summer or cold air in winter, you can feel the temperature without roof insulation as a barrier between your ceiling and roof area. You only have a thin piece of ceiling to stop the unwanted air from entering in your home. Roof insulation should always done by professional roof insulation contractors. Installing roof insulation is not cheap enough to buy the insulation and have this product incorrectly installed.  The material is compressed into plastic packages so the transportation is quite easy, but it will expand once released make sure not to compress it since it can lose its productivity. On the other hand, if your ceiling space is hard to access and there is no safe ground for you to step on, it is better to use some loose-fill insulation, which however needs to install by a professional. Contractors that specialize in installing roof insulation will always be well train and you will benefit from this. Roof insulation stops the air from outside your home from entering in through your ceiling.

Irrespective of the roofing system that you have installed in your property, roof insulation can go a long way in providing long-term benefits that that you cannot ignore. Though opting for roof insulation may add to your initial expenses, you will make savings in the long term. Therefore, if you are someone with foresight, insulating your roof will make sense. Think of roof insulation as a blocker. It blocks hot and cold air from moving into areas of your home that you do not want it to be and by keeping your indoor environment cozy in winter and most definitely cooler in summer. There are different types of insulation that is available for homeowners to buy. The preferred insulation by many people would be aerolite insulation.  Many people in the last few years have been looking into eco-friendly insulation for their roof insulation. Some roof insulation contains no itchy fibers that you could sleep with it like a duvet and you would not have any problems with chemicals. Choose the right roof insulation and the most environment-friendly offer, with no chemical additives.

Improve the sound environment

The ideal acoustic environment will provide you a good acoustic comfort. It is due to appropriate acoustic reverberation time and high speech intelligibility. Acoustic insulation typically used for music studios to enhance and improve the quality of sound or music inside a room. By installing acoustic insulation, neighboring rooms will thank you, as these products will limit the amount of sound coming out of your room. Acoustic insulation is also of particular interest in soundproofing. Acoustic insulation of sounds aims to reduce as much sound energy as possible, converting it into heat or movement, transmitting it away from a certain location. Acoustic insulation significantly reduces typical sources of sound leakage. Acoustic insulation will influence the overall acoustic atmosphere of a building. It is important to insulate all possible paths for flanking noise or sound leakage. Noise not only passes through a shared wall, but also finds flanking paths through poor joints between the wall and floor, poorly sealed penetrations, ceiling spaces, floor spaces, ductwork, and even other walls. Noise control solutions such as machinery housings or airborne sound silencers are also role of acoustic insulation in an area.

With acoustic insulation in a room, airborne sound generated by speech or music collides with the walls of a room, part of the sound's energy reflected, part is absorbed into the walls, and part transmitted to the adjacent room area. As the waves travel through the wall, the sound energy transformed into a heat caused by internal friction of the molecule and structural movement of the material. These materials of acoustic insulation properties attenuating the transmission of sound energy called sound transmission loss. Using acoustic insulation, it creates a calm and pleasant sound and improve the sound environment where speech more easily understood. In many residential projects, acoustic insulation on ceiling used in living rooms and television or music rooms. The acoustic insulation foam are sound absorber. This acoustic insulation foam used in a wide variety of applications ranging from recording and broadcast studios to commercial and industrial facilities. Acoustic insulation can be install directly to walls, hung as baffles or used as freestanding absorbers.

Acoustic insulation also have their application in several commercial setups such as in the field of education like auditoriums. May also install in lecture theatres, classrooms and halls, in public places like sports, functions, events and entertainment venues. Acoustic insulation is also applicable in commercial setups like offices, boardrooms and conference halls, in sound studios like radio, television and recording rooms, in retail setup like shops and shopping centers. Acoustic insulation products depending upon the sound traffic in your room or the kind of setup you own. It will reduce the maximum noise levels you encounter on a daily basis. You may install acoustic insulation to enhance sound quality or to keep outside noise entering into your space. Take into account the kind of job you do in the space where you plan to have acoustic insulation to your place. Acoustic insulation may be use in recording studios and performance halls. These acoustic insulation is to improve sound quality or within an area or conference space to cut noise levels.

Underfloor Insulation – Easier Installation than the Rest

Underfloor insulation is also listed as one of the priority areas to insulate in your home. The main idea is to keep your home warm and reduce your energy bills. Unfortunately, it is one area the least attended to among the obvious ones (the walls and the roof).

The main thing really is improving the insulation so you could save you with some sizeable amount every year. You may need to have some financial help (if you don’t have the budget for it) to be able to pay for your insulation that will be done by professionals.

From a practical point of view, it is a one-time expense compared to the yearly payment you fork over in keeping your place warm with no insulation on your floor.

Your floor

It is important to know your underfloor insulation type before staring on anything about the project. You can determine it two ways. First, if your house has a basement or a cellar, you might be able to see wooden joists and the other parts of the underside of your floorboards from below.

In this case, you might have a suspended timber floor. Most likely, too, you may have this floor type if there are ventilation bricks on the outside of your house that are below the floor level. If you cannot access the space underneath your floor, you need to lift a corner of the carpet and underlay.

Regulations

Another thing is that you need to comply with some building regulations. One of them is that if you are adding extra insulation to your existing floor, there are a number of issues to consider.

With this, you need to ensure your ground floor rooms meet the minimum room heights. Second, you need to achieve the minimum U-value (standard measure of thermal performance) and that you minimize the risk of fire.

Make use you get advice from building control officers of your local council before working on the changes.

Timber floor

There is need to anything damaged by damp, rot or infestation before you do any work. If your floor is above an unheated cellar or basement, have the insulation tightly between the joists and secure the netting.

You also need to fix the plasterboard to the basement’s ceiling. This will provide fire resistance. If your floor is not accessible from below, take up your floorboards to fit the insulation.

Concrete floor

When the insulation is over the slabs, the room will warm up faster when the heating is switched on. Keep the thickness of your insulation to a minimum to reduce of having the costly alterations on doors, stairs and others later because of increase of floor heights.

You can help regulate the temperature and prevent overheat if you insulate the floor underneath the concrete. If you have a damp proof membrane and is placed above the slabs, an additional one might be needed to protect the insulation from ground contaminants.

Underfloor insulation is not really that difficult to install. If you’re a good carpenter, carrying out the work yourself can save you more.

Insulation Batts – Most Popular

Insulation batts are the most sought-after insulation materials compared to the others like the rigid boards, foams, and loose fills. One of the characteristics that could be the reason in its popularity is that it is the most flexible insulating materials used to insulate floors, walls and ceilings.

Another advantage is that it comes in pure-cut panels and eliminates problems during installations. Batts are usually made from many materials like fiberglass, or rock wool, plastic fiber, and some natural fibers like cellulose or cotton.

They are capable of insulating most places in the house. They are used in insulating floors, walls, and ceilings, including the foundation walls. From fiberglass materials (or rock or slag wool), they are also available in recycled cotton. For thermal and acoustic insulation, cotton varieties are used.

Popularity

Insulation batts have the quality of being very effective and economical when installed correctly, preferable by professional installers. This is necessary because during installation, it is very important that the panels are correctly customized to fit the area where they are needed.

However, batts may not work well for reasons that they do not fill out spaces well enough. It is necessary, for best performance, that they fill out the whole space with no gaps, voids, compressions, or incompletely filled out areas no matter how small or inconsequential they could be.

Types

Fiber insulation has many types of pre-cut batts. The unfaced has insulation showing on both sides. Kraft face is the type with paper on one side to act as vapor barrier. The FSK is a batt with flame-resistant backing on one side.

The one with the dry right on one side is with the vapor barrier. The mold resistant variety has a special facing that had been treated to resist molds and mildew. The foil face is the one facing one side of the batt.

These batts can be cut out from continuous rolls, hand cut and trimmer to fit. Makers usually attach facings (like the Kraft paper or vinyl) for water vapor protection.

Batts with foil facing carry them on one side. Batts that are mold-resistant have special facings that had been treated to resist molds and mildew, while the dry batt has a small water vapor barrier on one side

Suited to wall studs spacing

Since batts and rolls are most sought-after, they are made available in widths suited to the standard spacing of the wall studs, attic trusses or rafter, and the floor joists. Continuous rolls can be hand-cut and trimmed according to fit.

Batts with special flame-resistant facing are available in various widths and are used in basement walls and other places where insulation are mostly exposed. The facing helps facilitate the fastening during installation. (Unfaced batts are actually a better choice when adding insulation over existing insulation.)

R value

Batts and fiberglass blankets usually have a thermal resistance (R-value) between 2.9 and 3.8 per inch of thickness.

Fiberglass blankets and batts have a thermal resistance (R-value) between 2.9 and 3.8 per inch of thickness. High performance fiberglass blankets and batts (those of medium and high densities) have R values between R3.7 and R4.3 per inch of thickness.

Depending on the thickness needed in houses, these values for insulation batts vary greatly.

Blocking Heat from Your Ceilings

A ceiling insulation is one of the most cost effective energy efficiency measures. Not everybody knows the importance of the ceiling insulation in the part of their houses. Effective ceiling insulation is the best barrier against the summer heat and the winter cold. A poor ceiling insulation allows substances (heat or cold) to escape outside through those tiny gaps and cracks that can appear in the long run. This can be taken care of with proper insulation added which is however only one of the potential benefits of ceiling insulation.

These are the common types of ceiling insulation:

Bulk insulation

Bulk ceiling insulation comes in two types:

Segments, which fit between the joists above your ceiling.

Blankets that are designed to be rolled out across the top of the ceiling and the joists.

Blankets

Blanket insulation consists of flexible fibers, most commonly fiberglass. Blanket insulation that covers ceiling joists prevents extra heat loss through the timber joists. When you’re topping up existing insulation, it can be easier to install blanket insulation than segments because you can just roll it over the top of what’s there already. Insulation that covers ceiling joists can make it harder for a person to move around the ceiling space though. Blanket installation usually costs less than other types of insulation.

Segments

If you install segments between joists, you need to put in higher R-value insulation to make up for the heat that gets lost through the timber

Loose-fill insulation

Loose-fill insulation is blown onto the ceiling. Loose fills are most commonly sold in bags and are blown into building cavities using special equipment. It can be an option if there’s not enough space in your roof to move around and install bulk insulation. Otherwise we recommend using bulk insulation (blankets or segments). Its safety, effectiveness and durability depend highly on the quality of the material used as well as the installer's equipment and experience. As it can settle or move around over time, the insulation can get into contact with the roof or roof underlay and cause moisture problems.

Proper ventilation in the attic is another factor to a good insulation job. It lets your attic breathe, evaporating moisture in the winter and keeping it cooler in summer. If you install a vapor barrier, you need one square foot of free vent area for every 300 square feet of attic floor area. Without a vapor barrier, you need twice as much ventilation. Vents should be located on opposite ends of the attic, with some near the top and others near the bottom to allow for good cross-ventilation. Whenever you install a ceiling insulation, don’t forget to consider the R values. The R value is a measure of a material's resistance to heat flow (thermal resistance). The higher the R value, the greater the resistance to heat transfer, the greater the insulating effect and the greater the energy savings. Different insulation products with the same R value will provide similar insulation performance, regardless of thickness or the type of material. Complete and proper ceiling coverage is essential to the performance of ceiling insulation.

Putting Wall Insulations in Houses Or Buildings

In a house or building constructions, many forms of insulation are included as a means of reducing the transmission of thermal energy through walls, ceilings and even floors. Basically, this helps keep heated interior space warmer in the winter and air-conditioned spaces cooler in the summer. Reducing the transmission of thermal energy not only makes spaces more comfortable, but it is also essential to controlling energy costs. All building materials have an inherent insulating property, usually measured on a scale known as R-value, but additional materials are integrated into the building construction specifically to add insulating value to the walls, floors, and ceilings. A good wall insulation halts the flow of heat into and out of the home which makes your home more energy efficient all year round. Insulation acts to keep both heat and air conditioning in the house, meaning your HVAC system will not have to work as hard and your energy bills will be lower. Insulation on exterior walls puts a blanket-like barrier between your living area and extreme outdoor temperatures. Insulating your walls can prevent this by limiting air movement, enabling you to save up to 40 percent in heating and cooling bills. A wall insulation can also reduce annoying sounds from outdoors and it reduces sound carrying from one room to another. With a wall insulation, you’re reducing sound transmission and maximizing your enjoyment of every room in your house. With insulated interior walls, there’s less worry about whether your home is too loud from the neighbors as the sound will not carry as much as when your walls are insulated.

Types of wall insulation that builders use:

Bulk insulation

Bulk insulation comes a form as segments or blankets. Segments are pre-cut to small standard pieces of insulation whereas blanket products come in rolls. Bulk insulation can be made from various materials including polyester, wool, and glass wool. Whatever material you opt for; a good wall insulation product should meet the correct thickness, highest R-value possible for the thickness of your walls and the right width for the stud spacing in your walls.

Injected or blown-in insulation

Injected or blown-in insulation is pumped into existing walls through small holes in the cladding or lining. It can be made from various materials such as urea formaldehyde foam, wool, glass wool fibers or polystyrene beads. Before putting in any type of insulation into existing walls, it is very critical to make sure the wall cladding is weather-tight and to check if there is a wall underlay behind the cladding. This is difficult to assess without opening the walls, so consult a registered or accredited building surveyor before you consider injected or blown-in insulation.

Also, you should put wall insulation into your interior walls of rooms that you do not use all the time. Heating or cooling these areas can be expensive, so wall insulation will help reduce energy costs. Ultimately, all exterior walls in your house should be insulated to effectively reduce the flow of heat in and out of the home. Insulating exterior walls should always be a priority over insulating the interior of the home. Putting a wall insulation can make a big difference within your home.
