The correct application method for external thermal insulation composite systems (ETICS) is the bead-point adhesion technique. This technique involves applying adhesive in a continuous bead along the edges and across the center of the insulation boards before fixing them to the substrate. The point adhesion technique, on the other hand, involves applying adhesive only at specific points on the insulation boards, which may not provide sufficient bonding strength and can lead to potential issues with the system's performance over time. Therefore, it is recommended to use the bead-point adhesion technique for proper and durable installation of ETICS. **

The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid. These points are specific to each substance and can be used to identify and characterize different materials. The boiling point and melting point are important properties in chemistry and are often used to determine the purity and composition of a substance. **

No, not every turning point is a saddle point. A turning point is a point on a curve where the derivative is zero, indicating a local maximum, minimum, or point of inflection. A saddle point, on the other hand, is a point where the surface curves up in one direction and down in another, resembling the shape of a saddle. While a saddle point can be a turning point, not all turning points exhibit the characteristics of a saddle point. **

No, not every saddle point is a turning point. A saddle point is a point on a surface where the surface curves up in one direction and curves down in another direction. This means that at a saddle point, the surface does not have a local maximum or minimum, so it is not considered a turning point. Turning points occur at local maximums or minimums, where the derivative of the function is zero. Therefore, while a saddle point is a critical point, it is not necessarily a turning point. **

The amount of insulation required for a facade renovation depends on various factors such as the climate, building codes, and the existing condition of the building. In general, the insulation should be sufficient to meet the energy efficiency requirements of the building and to improve its thermal performance. It is important to consult with a professional architect or engineer to determine the specific insulation needs for a facade renovation project. **

The roofing underlayment serves as a secondary layer of protection against water infiltration and helps to prevent leaks in the roof. It also provides an additional barrier against wind-driven rain and snow. In terms of insulation, the underlayment can help to improve the overall energy efficiency of the roof by reducing heat loss and preventing drafts. Additionally, it can provide a smooth surface for the installation of the final roofing material, such as shingles or tiles. **

A terrace point is not necessarily a turning point. A terrace point occurs when the derivative of a function is zero, but the function does not change direction at that point. On the other hand, a turning point occurs when the derivative is zero and the function changes direction at that point. Therefore, while a turning point is always a terrace point, a terrace point is not always a turning point. **

A turning point is not necessarily an extreme point. A turning point is a point on a curve where the direction of the curve changes, such as from increasing to decreasing or vice versa. An extreme point, on the other hand, is a point where the function reaches a maximum or minimum value. While a turning point can be an extreme point if it corresponds to a maximum or minimum value, it can also be a point of inflection where the function changes concavity without reaching a maximum or minimum. **
