Fire Rated Doors

All that you wanted to know about fire rated doors

A fire door has a fire resistance rating. It’s a form of passive fire protection system. The basic aim of this door is to stop the fire from spreading to different compartments of a building. Fire doors can be made from a variety of materials like:

  • Glass
  • Gypsum
  • Timber
  • Steel
  • Aluminum

All doors are required to meet the standard set by the fire protection services. The door frame consists of fire or smoke seals, the necessary door hardware and structure which help hold the fire door in place. When assembled together the components are known as a door set. It has a numerical rating which signifies the amount of resistance it can provide during a fire. Some fire doors are combustible while others are noncombustible. Sometimes carpets are run through fire doors to allow the fire to travel past the fire barriers.

Usually fire doors are kept closed at all times. While some doors are designed to remain open under normal circumstances, during fire these are closed automatically. Some doors are kept open through an electro magnet which is in turn is wired to a fire alarm system. It must be kept in mind that the movement of the door should never be stopped by an obstacle.

The fire door is to be installed carefully. If there are any gaps in the door and the frame these must immediately be filled by fire resisting material. Fire doors should be installed with the help of a professional carpenter.

At the time of inspection the following things must be checked thoroughly

  • There should be no open holes or breaks between the door and the frame
  • The glazing must be done in a completely professional manner
  • The door frame and hinges and all other equipment should be installed properly to prevent fire from spreading rapidly.
  • None of the parts should be missing or broken

According to the fire safety authority, the yearly inspection of all fire doors should be the responsibility of the residents of a building. It is extremely important that everything is in working order. Also care must be taken that other fire safety equipment is up to date as well. A security check should be run on a yearly basis to void all sorts of fire hazard.

If you are looking for fire rated doors in Sydney make sure you buy the equipment from a licensed dealer. This is important because you should be getting a fire door with the highest quality ad which should offer the kind of protection that you require. The usual way is to look around at some companies which manufacture fire doors. Do a bit of research on your own. In fact you could even visit the site and check out how these doors can be operated.

If you know someone who has had a fire rated door installed in their building, make sure you take a look at it. For more information on fire rated doors check out local suppliers.

 

How a Noise Attenuator Works

Reducing HVAC Noise

Heating, ventilation and air conditioning systems (HVAC) can become pretty noisy when in use. When used in hotels, HVAC systems can keep customers awake or even distract speakers in conference rooms. Although some air conditioners are noisier than others, proper installation of the systems ensure they run smoothly and produce less noise.

Engineers installing HVAC systems therefore have to find a way of keeping the residential and commercial HVAC systems silent so they do not make distracting noise when running. Noise attenuators, also called sound attenuators or mufflers, are used to keep the systems silent.

What Causes Noise in the HVAC System?

There are many reasons why HVAC systems can become noisy. However, system can still make noise even when new. This is because as the air is being transported through the ducts, vibration of the system causes noise. Also, as the fans rotate to move air, they produce noise as the air vibrates and the fins move.

As air changes in the system, pressure drops and noise is produced. Another major cause of noise is loose fixings such as bolts and nuts vibrating to produce loud, annoying noise.

Types of Noise Attenuators for HVAC Systems

There are two main types of noise attenuators used to silence HVAC systems. They can either be cylindrical or rectangular. Cylindrical attenuators are fitted in the ducts to silence noise from the inside. The rectangular attenuators are fitted over the HVAC system. Both of the attenuators use the same principle in noise reduction in the HVAC systems.

Rectangular attenuators have dissipative silencers that deliver acoustic energy in contact with the sound absorbing media inside it. The round attenuator comes with a head that spins and a cone shaped tail. The circular attenuator is also double walled.

Inside the interior wall is the sound absorbing insulation that helps keep the sound produced to the minimum. The attenuators reduce the noise but also maintain the pressure changes in the HVAC system so air flows through the system with ease.

How Does a Noise Attenuator Work?

Noise attenuators are used as a wholesome part of a HVAC system rather than in isolation for the best performance. They are used when the system is being installed for the best effect instead of adding them later.

Noise attenuators have sound absorbing insulation inside to keep the sound down. Acoustic insulation inside the noise attenuator contains millions of air pockets that absorb the acoustic energy as it passes, reducing the noise.

The insulation inside the attenuators vary in thickness depending on the frequency of the sound produced. Increasing the length of the attenuator enhances sound attenuation, affecting the pressure in the HVAC system.

Regular maintenance of the HVAC system is carried out to reduce noise. Maintenance ensures there is no loose fittings in the maintenance system that could significantly increase the noise.

Double-Wall Coffee Cups

Currently, the unique properties of double-walled coffee cups have made a number of people prefer them. One of these qualities is the experience of drinking out of these cups. Many people love these cups because of the look created when a beverage is poured into them. The inner walls of these cups are designed using varying shapes making the content inside them have an appealing look.

Moreover, these cups are known as the best due to their exceptional durability. This is enhanced by the double wall feature. As a result, the cups are the most preferable when it comes to consuming beverages. Double wall coffee cups have a number of differences when compared to traditional cups. The differences are realised when it comes to their nature of construction, their functionality, and the kind of experience they offer. The following are the main advantages associated with double-walled coffee cups:

  1. Ability to Retain Temperature

This is one of the major features that create a big difference between traditional cups and double-walled coffee cups. These cups are capable of retaining temperature without considering whether the beverages poured into them are hot or cold. The temperatures are retained without the issue of major losses in temperature. This is necessitated by the double wall which plays an essential role in minimizing heat and cold exchanges between the surroundings and the inner side of the cup.  This is what enhances the retention of the temperature of the poured beverages.

  1. Durability

These cups are considered to be more durable as compared to traditional cups. Their thicker bottom is what plays a vital role in the prevention of breakages or cracks. Moreover, the thicker bottom is the one held responsible for ensuring that the right balance is maintained while holding the cup in the hand and while placing it on a surface.

Furthermore, these cups are designed using high-quality materials that are essential to ensuring an increased durability. On the other hand, traditional cups are less durable and the chances of shattering and breaking are higher, especially when they are subjected to rough use.

  1. Visual Appeal

The appearance of double-walled coffee cups is superior and they come with many attractive designs that suit any requirement. Their double-walled feature is one of their unique features coming up in different patterns enhancing various designs. Every time a beverage is poured into one of these cups, it takes the shape of the cup which is more appealing. Moreover, the shape creates a great drinking experience without considering if the beverages are hot or cold. On the other hand, traditional cups have a less appealing experience when compared to that of double-walled coffee cups.

Height Safety

Most Common Mistakes to Avoid

When working with heights, one must take height safety systems seriously as it can save lives and lessen the risk of a serious injury. Even if it’s just the wrong choice of gears and equipment, it could lead to rooftop accidents you don’t even want to think about. Here are the following height safety mistakes that you should avoid in the process.

Not following the Australian standards

One must oblige to the Australian Standards. The standards are strict and non-negotiable. Hence, a height safety company must exhaust all means to comply with their requirements. The commitment of the employees to the said standards can save their lives and better their quality of services.

A poor height safety system

Designing a height safety system that will determine the safety of the roofer while he’s working is important. It requires vast knowledge and complete understanding of the Australia Standards to do so. The rooftop worker must be safe always when working. However, most common mistakes we see in height safety systems includes incorrect spacing between anchor points of the roof that prohibits the rope from reaching the second anchor point. Some designs have their anchors falling out of the pendulum that will automatically reduce the performance of the roofer.

Some rooftop workers do not also use a mini access ladder. Most of the rooftop sheets are damaged because a worker jumps from one roof into the other, resulting in an unsafe practice and greater risk of serious injury.

Not calculating the risks properly

In every design you make, you prioritize the safety of the rooftop worker above. Aside from that, you need to get rid of all the hazards as much as you can. Prevention system such as guardrails and walkways can help you in decreasing the risks. Measuring the risk of the personnel on the roof can also help you to design a better height safety system.

Using inferior products

When it comes to materials, one must use quality products that can provide stability to protect the worker at all times. Using aluminum that rusts in just a short period of time or an inferior stainless steel that might break any moment is one of the biggest mistakes you make when designing a height safety system.

Good design but incorrect installation

Even if you design the best height safety system, if you fail to install it properly you will most likely fail when you use it. Choose a qualified and highly-skilled installer to do so. In that way, you can rest assured that your rooftop workers are well-protected while they are six feet above the ground.

Now that you know the most common mistakes when it comes to designing and installing a height safety system, make sure to keep these tips in mind. The safety of the rooftop worker above all is the most prioritized when it comes to working with heights.

How to build a house: The Works

Foundations: Foundations are made by masons who install reinforcing reinforcement and concrete clean in the trenches.

The basement : these are the first bricks or blocks that are laid and will be under the ground. this basement can be a basement, a crawl space or a hedgehog (the ground floor then rests directly on the foundations).

The floor is then manufactured starting with the laying of concrete beams on the bricks. The slabs are then placed on the edges of the beams. The metal mesh is then laid and a concrete slab is poured.

The walls: it depends on the type of materials (cinder block, brick, monomur, cellular concrete, …). Everything is fixed with mortar glue. The lintels are placed above the openings.

In case of floor, other beams can be laid (concrete slab) or it can be elements of wood (wood floor)

Work begins approximately 6 months after the signing of the construction contract if you go through a builder. Such a delay is due in particular to the time required to file the building permit and the period of possible third-party appeal against this permit. This period lasts 2 months.

The construction phase of your home will vary from 5 to 15 months depending on the size of your home, its complexity and its environment

A rectangle house of 80m2 in the countryside will be built in a short time whereas a contemporary house of 150m2 floor with adaptations to the ground in dense urban environment will probably take more than 12 months. The construction phase passes through the following steps:

Big work

  • The Meeting starts worksite with the work supervisor. This also involves the development with your builder, phase that validates certain points, equipment and options.
  • The earthwork that consists of leveling the soil so that the house can rest on a solid foundation.
  • Then it is the excavation which consists in digging the site of the future house as well as the trenches used for the connections to the local networks (water, electricity, etc.). The depth of the excavation depends on the type of foundation (crawl space, single storey, ..) and the nature of the soil.
    • Roofing: the laying depends on the nature of the roof (2 OR 4 PANS, flat roof). The most classic roof, in 2 sections, goes through the creation of the gables.
    • The frame: the first beams are the sandpit faults which are fixed against the horizontal walls. Then the blackout is placed at the top of the frame, parallel to the sand pit faults. The gables are then trimmed with wooden boxes. We then fix the rafters (thin vertical beams) then install battens. The roofing screen can be fixed at this time.
    • Laying tiles (concrete, terracotta, slate, shingles …)
    • Laying roofs (top of the roof), hips (along the projecting angles), valleys (re-entrant angles), bays for ventilation and banks (roof edges). The house is then out of water
    • Laying joinery (doors and windows) so that the house evening out of the air.

    Once this structural part is finished, we go to the second work

Second work

The second work corresponds to the installation phase of all the equipment of the house and the finishes. It can sometimes be longer than the carcass phase depending on the finishes desired.

  • Installation of water and electricity circuits, more and more by the installation of hydraulic and electric octopus.
  • Installation of the inner or outer insulation
  • Laying interior partitions
  • Laying flooring
  • Laying of sanitary
  • Paint, plaster and other siding
  • Talus, VRD, and retaining walls
  • Airtightness test and compliance with thermal standards.

Then comes the handing over of the keys.

Note that you will have meetings of building sites at several stages. If you signed with a builder, you can have a meeting before each invoice, as these are defined by law

  • 15% at the opening of the site,
  • 25% upon completion of foundations
  • 40% at the completion of the walls
  • 60% out of water
  • 75% at the completion of the bulkheads and the shutdown
  • 95% upon completion of equipment, plumbing, carpentry and heating.
  • 5% at the reception,
