When it comes to roofing solutions, efficiency, durability, and cost-effectiveness are always top priorities. Sandwich panels provide a superior combination of insulation, strength, and ease of installation for new construction or renovation. Here's why you should consider sandwich panel solutions for your next roofing project:
A roof sandwich panel is made up of two outer layers, usually from pre-painted steel or other similar materials, while the insulating core forms the middle layer. This "sandwich" construction gives excellent properties to the panel for thermal performance and acoustic insulation. Some of the most common core materials used include PIR foam, mineral wool, and EPS, all providing specific benefits for particular applications.
Roof sandwich panels are designed to save heating and cooling costs. Having a PIR core ensures effective thermal barriers, reducing energy loss and lowering energy bills considerably. Such benefits work best in commercial and industrial buildings where energy consumption is higher than others.
Safety during selection, of course, is a top priority. Many sandwich panels have fire-resistance characteristics. For example, the high fire ratings boast for Ondatherm® T and Ondastyl® T panels. Ondatherm® T achieves fire reaction class B-s2,d0, meaning it doesn't catch fire. Ondastyl® T is classed as A2-s1,d0 against minimum requirements for non-flame-supporting materials.
Installation of roof sandwich panel solutions can be done very quickly and cost-effectively in terms of saving time and labor. Panels also come in a visible and secret fixing system, to enrich the aesthetic requirements of the project. It is thus easy to install, keeping disturbance at the site to a minimum, and helps complete the project as scheduled.
Roof sandwich panels are also very resistant to weather factors, especially if the outer cover is precoated steel. Actually, these sandwich panel solutions will not break down even under heavy rainfall, snow, or extreme temperatures. In addition, they have low maintenance costs. Thus, these are one of the long-term solutions for such weather-related problems.
Sandwich panels can be manufactured upon request in different thicknesses and designs. Delfos and Ondatherm T have various core thicknesses besides multiple widths to cover a wide range of roof pitches. While the thicknesses for Ondatherm T vary from 30 mm to 140 mm, you can achieve the right amount of building insulation.
Ondatherm® T - PIR foam insulated sandwich panel for buildings of low or medium hygrometric level. This product with trapezoidal steel facing and superior airtightness prevents thermal bridges. An energy-efficient roof solution. It is available in different thicknesses, and its PIR core ensures high thermal performance. Quality is assured through the ACERMI certification.
Delfos ® is an insulated panel that has a PIR foam and suits buildings having an inclined roof. The secret fix system for roof slopes from 4º makes the Delfos panels ideal for industrial and commercial properties. The available widths of Delfos® panels are 1,000 mm and 1,150 mm with insulation thickness ranging from 30mm to 100mm. Available in a wide range of coatings and colors.
For completely non-combustible installations, Ondastyl® T features a mineral wool core, exceeding stringent fire safety standards. It achieves an A2-s1,d0 rating, suitable for public access buildings and high-safety applications. Its trapezoidal facings and robust construction offer exceptional longevity. Perfect for low and medium hygrometry buildings.
Roof sandwich panels are extremely versatile and are applied in many industries. Some of the most common applications include:
Due to the ruggedness of the sandwich panels, they are quite ideal for use in warehouses, factories, and manufacturing plants. The thermal insulation of such panels brings about control temperatures inside huge open areas while being comfortable and energy efficient.
Fire safety is a top priority in public buildings such as schools, hospitals, and sports complexes. For these types of buildings, two of the best products are Ondastyl® T and Ondatherm® T, which offer top-of-the-line thermal performance and fire resistance.
Due to their energy efficiency, sandwich panels are also used in commercial properties such as offices and retail outlets, as well as in residential housing. Their ease of installation during construction also makes them ideal for most roofing projects.
Roof sandwich panels are a splendid solution for almost all buildings. However, here are a few crucial considerations before purchasing and installing the same:
The type of panel to be used needs to be matched with the purpose of the building. While some buildings may require much thicker insulation than the rest, thinner panels could work for others. Finally, energy requirements plus factors in the environment need to be considered before making the right choice.
The pitch of the roofing is a factor in choosing between the types of panels. Delfos® panels are best suited for pitches of 7% or steeper, whereas, for flatter pitches, Ondatherm T® or Ondastyl T® panels are used.
Although the initial cost is different, sandwich panels save more costs in the long term because they consume less energy to maintain a comfortable temperature inside the structure, have lower maintenance costs, and incur fewer labor costs due to easy installation.
A variety of different finishes and colors with different coatings will satisfy the technical requirements and aesthetic pursuits depending on whether it is a commercial or residential building.
Energy intake can be reduced using sandwich panels with a PIR foam core or mineral wool. A lot of the alternatives also use recycled materials to help maximize sustainability in construction.
ArcelorMittal offers innovative roof sandwich panels, namely Ondatherm® T, Delfos® and Ondastyl® T, providing extraordinary insulation, structural stability, and aesthetics for industrial, residential, and public buildings. The panels offer excellent thermal efficiency and fire-resistant properties. They come in numerous design options, allowing for flexible designs without compromising structural integrity. ArcelorMittal’s roof panels are highly attractive due to their focus on sustainability and energy efficiency. By using PIR foam and mineral wool cores, these panels help minimize energy consumption. The material also offers long-term savings and a greener footprint. Additionally, the panels are easy to install, require low maintenance, and are practical for both contractors and building owners.
