Sound Proof Insulation – More Effective and Less Costly

Currently, there are now several ways and means of soundproofing a wall and insulate it. Improvements in the sound proofing industry have created more products that are now more effective and less costly than it was before. Sound proof insulation had come a long way.

Principles

At this time, though, one needs to understand some of the main principles of sound movements and how to minimize or totally eliminate it. Some of the principles include getting the information that the effect of insulation is minimal in both low and high frequencies.

For a conventional wall, the effects of insulation are quite similar to having no insulation. The largest gains are just above the primary low-frequency resonance.

Experiments

Adding layers to a normal single wood stud well result in the effects of getting the gains in the mid-range higher at middle and high frequencies. In the low frequencies, however, the performance is not as good as with the lighter installation.

It is here where the STC (sound transmission class) ratings rise by a mere 2 points (from 32 to 34). Insulation has much more value in decoupled walls.

Low resonance points

In walls having mechanical connections between the two sides, the insulation has proven to benefits of insulation at middle and high frequencies. In low frequencies, the capacity of the insulating materials to absorb sound falls dramatically. The benefits of insulation at low frequencies are to lower the resonance points.

Lowering the resonance points is deemed valuable and in walls with damping or decoupling, the insulation has considerable value at middle and high frequencies which should be considered mandatory for any sound isolation application.

Less effective insulation

To demonstrate how insulation becomes less effective as frequencies fall, place a fiberglass in front of the mid and high frequency speakers in youth room and listen to what happens. The sound would probably be muffled or muted.

Afterwards, put the same fiberglass in front of the subwoofer cones. Nothing happens. This is the same with the walls.

STC (sound transmission class) ratings

When dealing with sound, one need to be familiar with STC ratings. STC ratings measure how much a particular sound proofing construction material reduces sound. (R-values in thermal insulation are the values of retained heat in the materials used.)

Higher STC ratings means the materials used are better at noise reduction. A wall with an STC rating of 30 will allow most sentences to be heard clearly in a conversation. A wall having an STC rating of 50 will block most of the loud speech and only transfer faint sounds of loud musical instruments.

Some guides

Often enough, people think using denser insulation materials cures every sound problem. Generally, it is preferable using standard building type insulation.

It is not advisable to use expensive and very dense insulation. In addition to the expense, they tend to make low frequency performance worse by raining the resonance frequencies.

The use of sound proof insulation is critical and valuable, but insulation alone cannot win, especially in conventional walls where direct structural connections exist between the sides.

Ceiling Insulation – Cost-Effective Measure

The ceiling is another vital part of the house that should be considered as well in deciding the places to be insulated. Like all types of insulation, ceiling insulation is a must if you are looking to have a substantial cut in your energy bills. Among others, it is the most cost-effective energy efficiency measure you can do.

For most houses these days that are using cathedral ceiling, or have attic walls that present unique insulation requirements, a proper insulation installation is needed to protect the whole house.

Insulating

In the planning stage and the ensuing installation of the insulation project, you need to ensure their statuses by checking first. You need to ensure that all the air lead through the top floor ceiling is sealed completely and thoroughly. Also, these insulation levels must exceed the local building codes.

There should also be provision of space for both the insulation and the needed air flow from the vents at the eaves.  The insulation coverage needs to be continuous.

Likewise, the area planned for storage should have enough space underneath needed for insulation purposes. The doors must also be insulated and sealed, with the knee wall areas having adequate insulation and air sealing barriers.

Techniques

Loose-fill or batt insulation are typically installed in attics. You need to put the backing next to the ceiling finish for the batts that has attached vapor retarders.

The costs for ceiling insulation vary, which is one of the major reasons for the choices. However, blown-in loose-fill attic insulation that uses fiberglass, rock wool or cellulose is usually less expensive than batts. They also give better insulation coverage.

Loose-fill

The first task is to seal all attics to home air leaks, especially the chases, bypasses and the fur downs. Insulation materials like the fiberglass and rock wool do not necessarily stop the air flow completely.

You then need to follow up the requirement clearances for heat producing equipments. These would consist usually of flues or exhaust fans. The other blocking requirement might be ruled by local building codes.

You can use metal flashing, plastic or cardboard batt files or pieces of batts or rigid insulation to do the blocking. To preserve the ventilation, you need to install rafter baffles for soffit vents in roof eaves. You can use insulation dams at the soffit, porch, and garage and attic to ensure full coverage.

Insulate over the attic access using a piece of batt. You also need to get complete insulation coverage at consistent depths, using rulers, if need be.

Batts

You need to ensure again that the attic is sealed against air leaks. You also need to block around heat-producing devices. It is important to cover the top of ceiling joints or bottom cord of truss with insulation.

You need to use the complete coverage of full thickness, non-compressed insulation. When installing the batts, ensure that they completely fill the joist cavities. Shake them to ensure proper loft. If the joist spacing is not even, pitch the gaps with scrap pieces.

Do not compress the insulation with wiring, plumbing or duct work. Ceiling insulation needs proper installation techniques and care.

Insulation – Essentials for Temperate Climes

Basically, insulation is the process of having a barrier to the heat flow that is needed in keeping your home warm in winter and cool in summer. A well-insulated home gives out year-round comfort, cutting cooling and heating bills for up to half the amount. In turn, it also reduces greenhouse gas emissions.

Climatic conditions have influence on the level and type of insulation. You need to establish whether the process is needed to keep heat out or in (or both). The process needs to cater to the seasonal as well as the daily variations of temperature.

Heat loss/gain  

If the insulation is installed but the house is not properly shaded, the built-up heat can be kept in by the process. This creates an “oven” effect.

Draught sealing is also important because draughts can account for up to 25% of heat loss in a home in winter. With the process, you can help in weatherproofing you house from moisture problems like condensation. 

Bulk / reflective insulation types

In bulk, the process mainly resists the transfer of heat (via convection and conduction). The basis is on the pockets of trapped air within the structure. The thermal resistance is essentially the same regardless of the direction of the heat flowing through it.   

The materials used in the bulk process include glass woo0l, wool, cellulose fiber, polyester and polystyrene. These bulk insulation products come with one material R-value for a given thickness.

Reflective insulation actively resists the radiant heat flow because of its high reflectivity and low emissivity (the ability to re-radiate heat). It relies mainly on the presence of an air layer at least 25 mm next to the shiny surface. (The thermal resistance of reflective insulation varies with the direction of heat flow.)

Ceilings / roofs

You need insulation under the roofing materials to reduce radiant heat gain. Install it in the ceiling to reduce heat gain and loss, mostly done in the joists.  To reduce risk in electrical short circuiting, the electrically conductive materials must not be laid across ceiling surfaces or ceiling joists or on subfloors.

The wall sections between ceilings of different heights (bulkheads) need to be insulated to the same level as the ceiling because they all are subjected to the same extremes in temperature.

Walls

The external walls should be insulated to reduce the heat produced by radiation, convection, or conduction. The installation on walls can be done within cavities, within stud frames, on the outside of stud frames or on the inside (or outside) of solid walls.

Depending on the present situation, some other forms of insulation can double as a moisture or vapor barrier.

Floors

Insulate the underside of suspended floors in cool temperature and alpine climates or in high humid and hot dry climates where air conditioning is used. Insulate the edges of slabs-on ground in cool temperate and alpine climates.

Raised timber floors need subfloor access to install insulation. Foil or bulk insulation works well but care must be taken to ensure it is well supported and won’t sag in time. Insulation is part of the set up in temperate climes.

Filling the Gaps or Cracks that May Exist

Make your home more energy efficient with insulation can keep your home warm in the winter and cool during the summer, it has a different types of insulation for attic, walls, floor, and crawl space, this are needed to insulate irregular spaces or wall cavities, loose fill insulation provides a great solution for panels and are easy to install, can even assist direct humidity with extensive option of multipurpose insulation that is ideal for many applications including insulating water pipes and water heaters. Install and maximize the insulation with the selection of insulation accessories including fasteners and foil tape, poly film can be used to provide a moisture barrier around insulation, foam and stretchable adhesive to hold and close leaks that assist to assure in contrast to moisture by protecting the foundation of home from drafts with foundation protection products like insulation rolls and batts are great for insulating your walls, floors, attics, and ceilings.
