Sandwich panels have found their place in the construction industry today. One of the most important issues in implementing sandwich panels is their insulation and sealing, which is done using insulation glue. The insulation glue used for this purpose has a special formulation that is different from ordinary glue. In this article from Parsin, we will introduce special glue for sandwich panels.
What is sandwich panel glue?
After installing the sandwich panels, in order to better seal and insulate the wall or ceiling covering, a special sandwich panel glue is used, the most important feature of which is its high adhesion. Such glue are usually used to seal all types of building materials, including metals, stone, and concrete.
This product has high flexibility and maintains its properties in any condition. Other features of sandwich panel glue include high resistance to temperature changes.
Sandwich panel insulation glue is also known as mastic glue in the market. Polymeric materials are used in the production and construction of sandwich panels, which is why using ordinary glue will damage the sandwich panel.
Insulating and sealing sandwich panels with special glues gives the facade a uniform and beautiful appearance, while also preventing energy waste and the possible penetration of moisture, rainwater, etc.
How to use sandwich panel glue?
Insulation glues are widely used in the construction industry. The most important reason for their use in sandwich panel structures is to insulate them. Using these glues is easy and does not require any special skills or expertise, however, there are some tips that will help ensure better and more practical results.
- Sandwich panel glue should be stored in a cool, dry place. Using and storing this glue at high temperatures can cause burns.
- For better adhesion and performance of the glue, you must clean the work surface thoroughly before use.
- The area where this glue is used must have the same dimensions and be square in shape.
- To reduce the depth of the glue application, polystyrene foam or sponge foam can be used.
- Primer can be used to prevent bubbles from forming on the surface of sandwich panels that are uneven and raised.
The best sandwich panel glue for ceiling panels
Polyurethane sealing and caulking glues are used to connect sandwich panel structures. This type of glue is considered the best and strongest sandwich panel insulation glue. Polyurethane insulation glues come in two forms: solid and flexible. These glues dry quickly in the presence of air, and their most important features are their waterproofness and high paintability. While it still has acceptable performance at different temperatures, this sandwich panel glue is generally used for insulating ceiling panels.
Two-component sandwich panel glue
These types of glues have a two-component composition and are usually used to cover deep horizontal seams in sandwich panels. The effectiveness of this glue is similar to that of twin glues, and after mixing and chemical reaction, it becomes bulky and takes on a flexible shape, which can be used to fill the seams well.
Conditions for using sandwich panel glue
The appearance of sandwich panel insulation glues is similar to a colored viscous liquid. It usually takes 30 minutes for these glues to react and the required temperature for use is 10 to 35 degrees Celsius. It usually takes about a full day for the glue to dry completely. In approximately one week, the sandwich panel insulation glue reaches the required final strength.
The importance of using sandwich panel glue
The most important reason for using these glues in sandwich panel structures is the strength, durability, and sealing and insulation of the sandwich panels. Sometimes, sandwich panel insulation glue is used to further adhere and connect the insulation foam to the panel sheets. Improving the performance of panel structures is not possible without the use of these glues.
The most important feature of sandwich panel glue
- High resistance to direct sunlight
- Extending the lifespan of sandwich panels
- Good flexibility in heat and cold
- Stability and appropriate resistance to various weather conditions and atmospheric factors
- Drying in the presence of air without the need for a dryer
- High resistance to ultraviolet rays
- non-toxic
- This glue is not a solvent for the raw materials used in making sandwich panels.
- Adhesion to various building materials
- Using it prevents energy waste.
- Simple and easy to implement without the need for special skills
summary
Sandwich panel glue is one of the factors that increase the lifespan of the structure and sandwich panel. These glues, also known as mastic glue and polyurethane glue, are used to seal and insulate panel structures better. A special formulation is used in the manufacture of sandwich panel glues that increases the strength and durability of these glues.
