Unique coating: Sandwich panel roof

Imagine having a roof that is more than just a surface—a sandwich panel roof provides an excellent barrier against the weather. This creative roofing solution is a unique option for contemporary building projects because it blends efficiency and durability. Sandwich panel roofs have a layered design in contrast to traditional roofs, which frequently have single-layer materials. Usually, two layers of metal or another strong material are layered on top of an insulating core material.

Sandwich panel roofs offer excellent thermal insulation as one of their main benefits. The core material acts as a barrier against heat transfer and is typically composed of materials like mineral wool or polyurethane foam. This insulation lowers heating and cooling expenses, which promotes energy efficiency in addition to helping to maintain comfortable indoor temperatures all year round.

Sandwich panel roofs are valued for their structural integrity in addition to their insulation value. Strong defense against weather conditions like wind, rain, and snow is offered by the outer layers of metal or composite materials. In the long run, sandwich panel roofs are a cost-effective investment because of their durability, which guarantees longevity. Furthermore, because they are lighter than conventional roofing materials, they can facilitate construction and lighten the overall weight of the building.

Sandwich panel roofs’ versatility offers a plethora of design options to architects and builders. The thickness, color, and finish of these panels can be changed to perfectly match a variety of architectural designs. Sandwich panel roofs provide a sleek, modern appearance that goes well with contemporary building designs, whether they are utilized in residential, commercial, or industrial settings.

In "All about the Roof," we examine the creative application of sandwich panel roofing, a special coating that combines energy efficiency with durability. Sandwich panels are stronger structurally and thermally than traditional roofing materials because they are made of insulated layers that are bonded together. This article explores how these panels promote eco-friendly designs and lower heat loss to improve building sustainability. We also highlight the advantages and useful uses of sandwich panel roofing, demonstrating why they are increasingly being chosen for contemporary building projects."

Features of the roof from sandwich panels

A sandwich panel is a material that combines insulation and finished roofing. Because building raw materials have a non-standard structure, the roof structure is gathered differently and gets simpler.

The device of the three -layer roof

Three layers are used to create a sandwich panel:

1. The upper steel sheet with stiffness ribs, protected by a film of polymers and zinc, which protects the material from adverse natural phenomena.
2. The insulation in the middle, which can be mineral wool, polystyrene foam, basalt and glass fiber or polyurethane foam is the best material that is proved by its high firewood.
3. The lower steel sheet, which protects the thermal insulation layer from the effects of vapors rising from the house.

Sandwich panels’ unique structure allows for the construction of roofs without the need for a complete rafter system. The roof’s three-layer slab roofing is as straightforward as possible: beams replace the Mauerlat on the side walls, and the skate is placed between the pediments.

Sandwich panel roofs occasionally have their rafter systems built, but only as a backup plan in case something unanticipated happens.

A few more runs are added to the main base elements beneath the roofing material if the distance between the Mauerlat and the ridge is too great and the sandwich panel sizes prevent it from being blocked. When the span length reaches 4 m, you will need them.

They determine the best intervals for adding more runs, taking into account the kind of sandwich panels. Since adhesive material is thought to be very tough, a step of two meters for supporting elements is appropriate, and three meters or less for cassettes. These plates look the same on the outside, but cassette sandwich panels are lighter and feature a ventilated space between the insulation and profile.

Narrowing the distance between the runs is not against the rules. The bearing capacity of the roof increases as the spacing between the base’s elements beneath the roofing material gets closer together.

The necessary angle of inclination

Sandwich panels can be installed on roofs that are at least 7° slanted. The only roofs that don’t qualify are those that are completely paneled along their entire length, have no windows, and have no openings for vertical structures like pipes. The material can be positioned at a 5 ° angle on them.

The selection of the roof’s angle is contingent upon the meteorological circumstances within the construction site. It is best to build a steep roofing slope—at least 40 °—if the predominant aspect of the local climate is continuous rains. The water will flow off the roof’s surface more quickly at a big angle. Furthermore, it is more prudent to construct a roof with a slope of 7 to 25 ° in areas with extremely little precipitation and plenty of hot days.

When building a steep roof slope, be aware that more materials will be required than when creating an almost gentle roof.

If the minimum bias rule is disregarded when building a sandwich panel roof, it can lead to several problems. Firstly, a lot of water will collect on the coating, which can quickly cause the seams to become less tight. When water turns into ice and back again during frosts and thaws, it ruins the material’s protective layer and starts the rusting process of metal.

Sandwich panels laid on wood, metal, or reinforced concrete bearing beams don’t require as many fasteners when installed on a 5 ° sloped roof as on a more steep roof.

Advantages and disadvantages of sandwich panels

Among the benefits of using sandwich panels as a roofing material are some that stand out in particular:

• excellent thermal insulation (to a greater extent – in panels from basalt fiber);
• efficiency and ease of installation and dismantling, regardless of weather conditions and climate of the area;
• small weight that eliminates the need to build a powerful supporting roof structure;
• The ability to easily replace the spoiled fragment of the coating, since it is assembled on the roof, like a mosaic;
• Special strength that allows the material without problems tolerate serious pressure of snow and wind and unexpected changes in temperature;
• long service life (more than 25 years);
• acceptable cost, because three -layer material simultaneously serves as waterproofing, insulation and finish coating, which is why the price of the entire construction site is reduced.

Sandwich panels have several drawbacks, including:

• air permeability, due to which it makes sense to create forced supply and exhaust ventilation in the roof;
• the presence of harmful substances in the atmosphere when exposed to severe heat. This property is inherent only in two types of insulation – polystyrene and polystyrene foam.

Installation of sandwich panels on the roof

You need to prepare specific tools and familiarize yourself with the instructions before you install sandwich panels on the roof base.

Necessary tools and materials

You must have specific tools ready in advance because when building a sandwich panel roof, the material needs to be cut, fixed, and the joints need to seal.

One of the following tools works best for cutting three-layer panels:

• electric scissors;
• saw with small spikes (for cold cutting);
• cutting disk.

When working with sandwich panels, it is not acceptable to use a hot cutting device or an abrasive circle grinder. The three-layer material will become deformed and partially lose its protective membrane as a result of the cutting area heating up, which will cause the coating to rust.

When installing sandwich panels, in addition to the necessary cutting tools, you will need:

• a mechanical or vacuum capture that will help to transfer the material;
• long self -tapping screws made of steel (stainless or carbon) with a drill at the end and washer to them;
• Synthetic rubber seal as a sealant for fasteners;
• electric drill (or screwdriver) to tighten the fasteners.

The length of the screws affects both the panel’s length and the kind of material it is fixed to. Elements are typically 12.5 mm in size when attaching three-layer material.

Chat under a sandwich panel

The crate of one kind or another can serve as the foundation for attaching a three-layer material.

• wooden;
• metal;
• reinforced concrete.

Table: Advantages and disadvantages of the types of crate for sandwich panels

Type of crate	pros	Minuses
Wooden	Low cost, harmlessness, low heat conductivity, ease of assembly	Big risk of ignition, the likelihood of insect damage
Reinforced concrete	Insurance from rust, low thermal conductivity, lack of need for considerable insulation, acceptable price, strength, long service life	Huge weight
Metal	Light and quick structure, versatility, constancy of form (does not give shrinkage and therefore is not covered with cracks), increased strength, prolonged operation	High cost (however, it is lower than that of the reinforced concrete structure), the need to process the means against rusting (for example, paint), a lot of thermal conductivity, obliging to use non -combustible heat insulator

The spacing of the frame’s components should allow the panels to be fixed at a distance of 5 cm from the edge, and support was required beneath the plate collection area.

Installation process

The sandwich panels are installed on the roof in phases:

1. The panel is transported to the roof, clinging to it vacuum suckers. At the points of fastening of the lifting mechanism, the protective shell is removed to the surface of the material.
2. The first three -layer slab with self -tapping screws is fixed on the overhang in the left corner of the roofing of a roofing. Fasten elements are placed strictly perpendicular and twisted with screwed without excessive pressure.
3. At the stove, which will be laid above the first, a piece of steel sheathing is cut off from below. Its width should almost correspond to the overlap of the panels (see. P. 4). A layer of insulation under remote metal is necessarily removed. The protruding edge of the upper metal sheet of the sandwich panel is lubricated with sealant.
4. The second plate is fixed above the first. The member of the panels is performed with a 30 cm overwhelm, when the roofing slope is tilted to 10 °, or 20 cm, if the roof is built at an angle of 10–20 °. Self -tapping screws are screwed into the intersection of the slab with the frame and the combination area of ​​two panels.
5. Having laid out the first row of material, perpendicular skate, the second is mounted nearby. Before that, the sealant is laid in the outlets of locks from the inside. The connection of two rows of the material is carried out using both grooves and fasteners twisted into the zones of the contacts of the plates with a crate.
6. Subsequent rows of sandwich panels are laid out according to the same scheme. After fastening the additional elements, all areas of adjacence are covered with sealant.
