Ventilation ducts in a private house. Materials from which they can be made

We frequently concentrate on insulation, heating systems, and even renewable energy sources when it comes to creating comfortable and energy-efficient homes. Ventilation is a factor that’s equally important but frequently disregarded, though. In addition to ensuring high-quality air, proper ventilation also helps keep the environment healthy and guards against problems like mold and moisture buildup. Ventilation ducts are essential for moving air around a private home because they let in fresh air while driving out old air. The various materials used for ventilation ducts and their benefits and drawbacks will be discussed in this article.

For effective airflow and system longevity, selecting the proper material for ventilation ducts is crucial. Sheet metal ducts, which are usually composed of aluminum or galvanized steel, are one popular choice. These ducts are appropriate for both heating and cooling systems because they are strong and resistant to high temperatures. They also give air a smooth surface to travel over, reducing resistance and enhancing efficiency all around. Nevertheless, installing sheet metal ducts can be expensive and necessitate specialized knowledge.

Flexible ductwork is another well-liked option for ventilation ducts; it is frequently made of coils made of both plastic and metal. Flexible ducts are perfect for retrofitting existing homes or spaces with limited access because they are lightweight, simple to install, and can be maneuvered around obstacles. They are more vulnerable to damage from sharp objects and incorrect installation, so they might not be as strong as sheet metal ducts.

Ducts made from recycled materials, like fiberglass or cellulose insulation board, are a viable option for those seeking a more environmentally friendly solution. In addition to having a minimal negative impact on the environment, these materials have good thermal insulation qualities, which aid in preserving a constant temperature throughout the house. To stop air leaks and energy loss, however, it’s crucial to make sure that insulation and sealing are done correctly.

Finally, some homeowners might choose to install ducts composed of ABS (acrylonitrile butadiene styrene) or PVC (polyvinyl chloride) plastic. These materials are a cost-effective option for ventilation systems because they are lightweight, corrosion-resistant, and reasonably priced. However, adequate ventilation and safety precautions should be in place due to concerns about the possible release of hazardous chemicals during manufacturing or in the event of a fire.

To sum up, ventilation ducts are an essential part of every private home because they improve comfort, energy efficiency, and indoor air quality. It’s important to take durability, cost, environmental impact, and safety into account when choosing materials for ductwork. Homeowners can benefit from a well-ventilated and healthful living space for many years to come by selecting the appropriate materials and making sure the installation is done correctly.

Materials for ventilation ducts

Private residences are permitted to use nearly any type of building material for the layout of their ventilation ducts. For instance, the house’s ventilation system could be built of wood not too long ago, and it worked admirably.

Such a system is acknowledged to be inappropriate for contemporary residential buildings due to the rapid cooling of the warm air flow rising to the surface, which causes the surface of wooden elements to appear damp due to condensation. The wood quickly deteriorates under its influence, and ventilation will be disrupted.

Three different types of building materials are now used in the construction of ventilation ducts to guarantee the proper operation of ventilation.

Full-body bricks

Brick ventilation system

These days, it’s standard procedure to arrange ventilation using bricks. It is resistant to moisture, strong enough, and long-lasting. The benefit of full-body brick is this. The size of the ventilation riser and the structure’s heavy weight are two of its drawbacks. Install a brick ventilation duct in the house’s wall so that the large structure doesn’t take up any space in the living area. To guarantee the stability of the entire structure, an additional foundation will need to be laid if this ventilation system variant is used.

Typically, the project offers an internal 140 x 140 mm ventilation space. It considers the duct’s height as well as the indoor and outdoor air temperatures. This is required in order to accurately compute the technical parameters, as well as the air circulation speed and hourly air exchange volume. Inside and outside temperature variations have an impact on the flow velocity within the brick shaft.

Such ventilation will produce exhaust with a volume of 140 m3 per hour if the channel is six meters long, the air inside is heated to +20 degrees Celsius, and the outside temperature is +5 degrees Celsius. This is more than sufficient for a 52 square meter room. Brick ventilating ducts are therefore appropriate for the majority of contemporary residential structures.

An exhaust hood with greater power, able to provide three times the air exchange of residential ventilation, is necessary for gas-fired boiler rooms. Therefore, if the boiler room’s area doesn’t exceed 17 square meters, a system similar to this one in a gas boiler room can function well. м. Large boiler rooms will require increasing the channel’s internal space, with calculations made using a unique table.

Prefabricated ventilation duct from monolithic elements

Single-piece ventilation duct

Individual residential construction projects are just now starting to employ this kind of design. However, it has already shown to be effective. Prefabricated construction has thinner walls and is substantially lighter than brick construction. It is put together using a constructor’s principle, creating an interior ventilation duct that is the right size.

Prefabricated construction has only two drawbacks: it is not yet widely used in the construction industry and can be very difficult to purchase, not to mention that it can be challenging to pick up the parts with the correct cross-section.

Construction assembled from pipes

Duct for ventilation made of regular PVC pipe

There are occasions when the project permits the use of any kind of pipe. These could be PVC, asbestos-cement, or light metal pipes. A thin, lightweight, and sturdy rectangular ventilation duct that is also simple to assemble is made of individual plastic components.

At first glance, a ventilation design like this might seem like the perfect solution, but only if all of its drawbacks are considered. There are multiple of these at once in plastic ventilation ducts, and they are pretty important.

First of all, PVC is flammable and will aid in the spread of fire if there is a fire in the room. Second, condensation will unavoidably form inside the channel due to the plastic walls’ inability to absorb moisture. This implies that you will need to maintain the system for eliminating accumulated moisture or find a way to insulate the PVC ventilation structure.

You can select the most ideal and practical type of home ventilation system after learning about the composition of the ventilation channel, evaluating the benefits and drawbacks of various ventilation system types, and examining the characteristics of the materials used to assemble the systems.

In a private house, the ventilation ducts play a crucial role in maintaining air quality and regulating temperature. These ducts serve as pathways for air to flow in and out of the house, ensuring proper ventilation and preventing the buildup of moisture and pollutants. When it comes to materials for these ducts, there are several options available. Common choices include galvanized steel, which is durable and resistant to corrosion, and PVC, which is lightweight and easy to install. Flexible ducts made of materials like aluminum foil or polyester are also popular for their flexibility and affordability. Additionally, some homeowners opt for insulated ducts to improve energy efficiency and reduce heat loss. Ultimately, the choice of material depends on factors such as budget, ease of installation, and specific needs of the house. By selecting the right materials for ventilation ducts, homeowners can ensure better indoor air quality and comfort while maximizing energy efficiency.

Material Possible Options
Metal Galvanized steel, aluminum, stainless steel
Plastic PVC, polypropylene, fiberglass reinforced plastic

The selection of duct material is an important factor in the ventilation system of your home. Every material, including PVC and metal, has advantages and disadvantages that can affect how long your ventilation system lasts and how effective it is.

Many homeowners prefer metal ducts because they are strong and fire resistant, especially when it comes to galvanized steel or aluminum. They are less vulnerable to environmental variables and pest damage, and they can tolerate high temperatures. But installing metal ducts can be more costly, and insulation might be needed to stop condensation from accumulating.

PVC ducts, on the other hand, are inexpensive, lightweight, and simple to install. In most circumstances, they don’t need insulation because they are corrosion-resistant. PVC ducts, however, can break easily over time and might not be as strong as metal ducts, particularly in very cold weather.

A compromise is provided by fiberglass ducts, which have insulating qualities and are reasonably lightweight and simple to install. They can help cut down on energy loss by maintaining the proper temperature of the air inside the ducts and are resistant to corrosion. Nonetheless, fiberglass ducts might be more vulnerable to moisture damage and need to be properly sealed to stop air leaks.

The material you choose for your ventilation ducts ultimately comes down to a number of considerations, such as your home’s needs, durability, and budget. To find the best solution for the heating and insulation needs of your home, it’s critical to carefully consider the advantages and disadvantages of each option and seek professional advice.
