Lightweight Framed Construction: Sound Attenuation Strategies Used to Make Building Comfortable for Occupants

Lightweight framed construction is one of the fastest ways of building a sustainable home. Unlike the traditional method of using bricks or concrete blocks, lightweight framed construction relies extensively on timber. This adds to the aesthetic appeal and environmental performance of your home. However, you might be concerned about the noise levels in the house since timber has a poor sound attenuation level when compared to other materials like concrete. Thankfully, engineers can select various noise insulation techniques to ensure that your timber-framed house has the right level of noise insulation. The following are some of the techniques employed by engineers for sound insulation in lightweight framed construction: 

Seals for Windows and Doors

The first strategy used to insulate sound is sealing off windows and doors. Small gaps between the window frames, door frames and walls play an important role in transmitting sound between the interior and exterior space. Engineers will, therefore, use intermediate timber pieces, tarry, rubber or plastic materials to fill any gaps around doors and windows. To add on that, power outlets and switches in your house will not be installed back to back. They will be fitted in different air spaces on either side of the noggin or studs (vertical pieces of timber making up the cross-sections of the wall).

Dense Layers of Plasterboard

The density of the plasterboard used in a given area is very important in determining the sound reduction index (Rw) of the timber used for lightweight framed construction. Basically, the sound reduction index is a measure of the effectiveness of a material as a sound insulator. The denser the layers, the better the reduction index. When setting up your walls, the engineers will use multiple high-density plasterboards that vary in thickness for optimal sound insulation. This is much easier than using a single thick layer of plasterboard, which presents lots of handling challenges.

Structural Separation

Structural separation is another reliable mechanism of reducing noise transmission. Here, walls are set up in such a manner that there are two horizontal joists separated by a small gap between them. The horizontal joists act as an anchorage for the vertical studs throughout the cross-section of the wall. Resilient furring channels such as top hat steel battens are fixed to every second stud using a resilient clip to further achieve the separation. In this way, the resilience enables the channels to bend, compress, stretch and later regain their shape. They absorb the sound by compressing or stretching and then damping it when they regain shape. Therefore, minimal sound is transmitted as impact noise.

Things to Have in Mind When Choosing Timber for Your Flooring Project

Choosing the ideal flooring material for your home is an essential part of a construction or property renovation project. Timber is one of the most durable materials that can add a naturally beautiful appearance to the home. It can be used to give the floors a contemporary, country, or rustic appearance depending on the type of wood and finishes that you choose. However, there are numerous types of timber out there today, and not all are suitable for flooring. Read on for some things you should have in mind when choosing timber supplies for your floors so that you can get the most out of the project.

Solid vs. engineered timber

There are two broad categories of timber: solid timber which comprises hardwood and softwood species, and engineered wood which is made up of various particles, fibers, or boards or wood products that are bonded together using adhesive.

Hardwood and softwood can both be used for flooring, but they have different properties. Softwood species include cedar, spruce, fir, and pine. They are low density and are lighter than hardwood, and this makes them a cheaper flooring option. Hardwood species include oak, mahogany, and teak. They are heavier, more durable, and more expensive than softwood.

Engineered wood is a durable flooring material that is neither as expensive as hardwood nor as cheap as softwood. The primary advantage of engineered wood is that its properties can be improved to give the wood moisture or water resistance, something that can’t be achieved with solid wood unless it is finished. Engineered wood is particularly suitable for underfloor heating applications.

Style of the timber

Timber can be cut in various styles to give the floor a desired appearance, design, or feel. For instance, you can use two or three strip floor that makes the flooring look busy. If you want a less busy look, you can use wide timber boards for the floor. Wood planks can be accentuated on the edges to add style or installed plainly to create a flat surface. Assess your style and the look you want to give your floor then choose the ideal design, size, and accents for your timber.

Surface finish

Surface finish can significantly determine the durability and appearance of timber. When dealing with solid wood, you want to choose a finish that will provide water resistance and improve the wearing resistance of the floor. If you are installing the floor in high-traffic areas, you need to choose durable finish that will extend the durability of the floor. Finish can also give your floor a shiny, matte, or subtle look with low sheen. Have these issues in mind when choosing a finish to ensure that it delivers in terms of durability and aesthetics.

Installing a timber floor requires that you have the above issues in mind so that you can get durable, functional, and aesthetically appealing floors.

Demolishing At Home? Talk To A Concrete Crushing Company

If you are planning to carry out any demolition work at home, it’s a good idea to liaise with a concrete crushing company. This is because a concrete crushing company provides many services that relate directly to demolition services. Below, find out what these demolition-related services are, how they can be of help to you during a demolition, and more.

Situations that apply

So which demolition situations exactly apply here? They include the following:

  1. Remodelling exercises: If you are planning to redesign your house, you might have to tear down some walls as you expand certain rooms or build extensions.
  2. Full demolitions: If you have an old, unsafe or outdated property, you might be planning to demolish it completely in order to build a newer, safer and modern house.
  3. Demolition of outdoor structures: You might be considering demolishing outdoor structures around your house, either to create space for new developments or in order to get rid of them for good, e.g. garage, patio, shed, etc.

What a concrete crushing company can do for you:

If you are planning to embark on any of the above demolition exercises, you can benefit from a crushing company’s services in the following ways:

  1. They can help you dispose of the building waste by removing it from your property, often free of charge.
  2. They can recycle the resultant concrete or brick waste by crushing and screening it for you at a fee.
  3. They can buy the building waste from you altogether at a modest fee.

Why work with a concrete crushing company during a demolition exercise?

There are several reasons why a concrete crushing company complements a demolition exercise so well. They include:

  1. You get to dispose off your building waste in an environmentally-friendly manner. The waste is put back into construction instead of being dumped in a landfill site.
  2. You get a chance to recycle the building waste yourself by re-using it for your future projects.
  3. If you choose to recycle your building waste, you get to cut your building costs significantly.

A concrete crushing company can turn your waste building waste into different materials such as fill sand (fine or coarse), road base (ideal for road construction, paving or drainage), and aggregate (used for concrete). Note that apart from selling your waste to them or seeking recycling services, you can also buy the above-listed products from them at any time for your build, whether you’re demolishing or not. For more information, see a business such as South Coast Concrete Crushing & Recycling.

Smart Glass Explained

More and more Australian offices and homes are turning to smart glass as the perfect solution for providing both privacy and thermal control. Smart glass becomes darker when it is exposed to sunlight, thereby reducing the amount of heat energy that enters the building. Not only can this reduce air conditioning costs, but also it means that you can see clearly out the window at all times, even in the heat of the day, when bright sunlight can be a nuisance. As the sun lowers in the sky, smart glass allows more light to flood in, meaning that electrical lighting costs are also minimised. Overall, chromatic glazing has many advantages over traditional glazed windows, but how does it work?

Electrochromic glass, as smart glazing is referred to in the industry, is a submembrane of a window fitting that can be made of either plastic or glass. The tinting membrane is made up of several fine layers put together by a process of sputtering. When fully made, there are five ultra-thin membranes on the inside of the window’s pane. There is a separating layer in the middle of these five layers with two electrode layers on either side of the layer. Outside of the layers are twin transparent electrical contact membranes. When no electrical power is supplied to the electrode layers, the glazing is clear. Window tinting is achieved when the electrode layers are charged. When powered up, lithium ions in the electrode layers move from one electrode to the other. As more of these ions reach the outer-facing electrode layer, the window gets more tinted, and more of the sun’s rays are reflected away.

One common misconception concerning smart glass is that it requires constant electrical energy to keep the sun out. This is not so. Yes, a charge is required to get the ions moving through the separating membrane initially, but the energy of the sun is all that is needed to keep the window functioning fully. As the sun goes down, the energy level drops and more lithium ions migrate back to their original position, allowing more light in. Therefore, very little energy is required to keep an entire installation of smart glass running. The system can be entirely automated if a photo-sensor trips a circuit to engage the initial power burst when the sun comes out. When you consider the energy savings these glazing units can bring to a building, the amount of electricity they consume in operation is minimal.

Trends and Upcoming Changes in the World of Construction Recruitment

If you own or manage a construction company, you undoubtedly are feeling the effects of the employment crunch. The increase in building projects has not been supported by an increase in workers, and as a result, construction companies have to be creative in their search for new talent. What’s happening in the world of construction recruitment? How can you get a leg up on your competitors and find the best workers in the industry?

Here’s a look at what’s happening and what’s on the horizon in terms of recruiting construction workers:

1. Booming gig economy

Whether you work with tradespeople, writers, consultants or cab drivers, you’ve probably heard the phrase “gig economy” bandied about. As part of the expansion of the gig economy, more and more tradespeople are setting up their own independent consulting businesses.

You can find these one-man bands on job boards, through internet searches or by networking with others in the industry, and they do everything from project management to quantity surveys to everything in between. The upside of hiring a professional on a gig basis (for a short time period) is that you only pay for what you need, rather than hiring someone for the long haul. The downside, however, is that these professionals may not have the commitment to your company that a full-time employee may have. Additionally, you may need to draft a non-disclosure statement so they don’t share details of your project with your competitors.

2. Continued stability of recruitment companies

From an employer’s perspective, the issue with the gig economy is that it can place the burden of recruitment on the employer, taking up valuable time. This is especially true in cases where the employer is looking for a highly skilled trades person or consultant as described above. However, construction company owners and managers who want to outsource that part of the process can still work with recruitment companies.

Recruitment companies find quality workers, and they match them to your needs. However, to ensure you get the best employee possible, you should work with a reputable company that has its insurance and liability policies in place, as well as a long history of customer satisfaction.

3. Apps on the horizon

As the construction recruitment industry continues to change to meet the needs of construction companies and workers, apps may fill in the gap. For example, this trend has already started in Singapore. There, construction workers whose visas are expiring may create a profile with their credentials, and construction companies who buy a subscription to the app can easily search through the profiles and hire a worker. As so much of the Australian building industry relies on immigrant labour, a development like this would not be surprising in the world of construction recruitment in the near future.
