Composition and Installation of SIP Panel
For over ten years, Panel Sandwich Group has been providing homeowners, architects, builders, and installers with innovative design, construction, and project planning solutions for both newly built and renovated buildings. Within our wide range of construction materials, the SIP Sandwich Panel is the ideal choice for achieving a more aesthetic appearance at a highly competitive price, suitable for all types of budgets.
Although we manufacture the SIP Panel according to each client's requests, the most common thicknesses range from 40 to 80 mm (up to a maximum of 120 mm),always considering the individual needs of each client to achieve adequate and comfortable insulation. This wooden ceiling has a polystyrene insulation core of around 35 Kg/m³, protected by a waterproof wooden board on its exterior and the client's chosen finish on its interior. In addition, we also produce other types of cores, such as Rock Wool and Natural Cork, specially designed for eco-friendly homes. Its main function is to provide excellent thermal insulation, combined with an elegant interior finish.
The outer sheet serves to protect against impacts, moisture, and thermal leaks. It is made of waterproof particleboard with a thickness of 16 or 19 mm. In this way, the Sandwich Panel is protected without the need for additional treatments that could increase the price. As for the interior finish, you can choose from natural wood boards, gypsum boards, natural flooring, or other interior finishing products you prefer, without the need to invest in additional materials.


Assembly of SIP Sandwich Panel
After learning about the features and benefits of the SIP Sandwich Panel, we will now explain the installation process in detail. Like all sandwich panels, the SIP Sandwich Panel is easy to install and ensures a flawless finish. When installed on the roof, a double grid is used, allowing for double roof ventilation and better air circulation. This way, better insulation is achieved, and leaks are prevented.
The panel is installed directly onto the structure, which can be made of wood or metal. If a wooden structure is used, the recommended anchor penetration is 50 mm. At Panel Sandwich Group, we want to inform our customers that it is always recommended to install tiles or any other exterior finish, such as sheet metal or tegula, on the top to achieve the best results. By waterproofing the sandwich roof on its exterior with asphalt fabric, we achieve maximum watertightness in the SIP panel. This is very important in USA, where precipitation can be abundant and prolonged. Proper roof waterproofing is crucial to prevent water leaks and protect the structure from moisture and corrosion. Therefore, we recommend using asphalt fabric when installing sandwich roofs to achieve efficient sealing and prolong the roof's lifespan.
To ensure proper performance, it's essential to verify during assembly that the SIP sandwich panel rests on three supports on each sandwich sheet. Thanks to its excellent tongue and groove installation system, we can cover large areas of sandwich panels in record time. This has an important and beneficial consequence: the decrease in time and economic costs.
The union between one sandwich plate and another is completely efficient thanks to this panel joining system, being screwed to the structure to ensure at all times the waterproofing and prevent the entry of humidity, also maintaining a stable temperature inside the room. To ensure the maximum protection, it is recommended to install the wooden roofs to a running joint between the rows, alternating the joints to ensure the suitability of the installation.

Why use SIP Sandwich Panel?
The main advantages of our sandwich panels with different interior finishes, compared to other models, are:
- They offer excellent thermal insulation thanks to their internal core and the wide range of densities available, which allows the panel to be adapted to any climatic condition necessary for the project. In this way, you can improve the energy efficiency of your home, which will translate into savings in energy consumption.
- This material has a great capacity to absorb sound compared to other similar construction materials. We provide different cores of Extruded Polyurethane, Expanded Polyurethane, Rock Wool and Natural Cork so that you can get a customized panel according to your specific needs.
- It has a wide aesthetic variety, which allows it to adapt to the characteristics and finishes of any project. Thus, we will always have the ideal panel available for you. With ideal finishes for both projects with a more classic aesthetic and for those more innovative: our wide variety of panels gives you a large number of options to choose from.
- They are easy to install and maintain, because they are light and do not require much experience in the construction area for their placement and care.
- Because it is made of resistant materials that do not require constant care, the maintenance costs are very low.
Tips for installing SIP Panel
At Sandwich Panel Group we offer all the necessary guidance to effectively install our products. Therefore, we give you three important tips that will help you install our panels easily and guarantee their maximum performance throughout their useful life.
1- Joint sealing with Butyl Tape
This is an alternative adhesive to traditional silicone. Silicone is no longer a viable option, as its lifespan is very short.
Butyl tape, available in various colors to suit any type of panel, has two important functions: covering the joint between panels where there is no protection from finishes and promoting waterproofing. Its main advantage is that, once installed, it will remain in good condition for a long time without losing its technical properties.
2- Cleaning of the screwed areas
It is advisable to clean the areas of the covers where cuts or drills have been made during the screwing between panels. This will prevent deterioration in the most fragile points of the Sandwich Panel and the formation of bubbles when waterproofing the exterior face by removing any possible remnants that may remain
3- Packaging and Protection
All sandwich panels that we send to our customers are protected and wrapped in plastic to help with their correct conservation, avoiding possible damage in their handling and unloading process.
