Question 1

How should I address intersections of extruded panels with doors, windows, beams, and columns?

Accepted Answer

Specialized node treatment is essential at junctions with doors, windows, beams, and columns. This involves employing flexible sealing materials, metal corner guards, and other techniques to ensure continuity and integrity of the thermal insulation layer, guarding against thermal bridging and moisture infiltration.

Question 2

Are insulation extruded plastic boards fire-resistant?

Accepted Answer

Basic extruded plastic boards lack inherent fireproofing. However, some market offerings incorporate flame retardants to achieve a certain level of fire resistance. Selection should align with project requirements to meet fire safety standards.

Question 3

Should I be concerned about the aging and degradation of extruded panels?

Accepted Answer

Extruded panels crafted from polystyrene resin exhibit commendable weathering and aging resistance. Yet, prolonged exposure to harsh environments can affect performance. It's advisable to select products of dependable quality that adhere to standards.

Question 4

What is the lifespan of insulation panels?

Accepted Answer

High-quality interior and exterior wall insulation extruded panels boast a lengthy lifespan, spanning several decades, while maintaining excellent thermal insulation properties. However, actual longevity depends on installation quality, environmental conditions, and other factors.

Question 5

How do I determine the appropriate thickness for extruded panels?

Accepted Answer

The thickness of extruded plastic panels should be chosen based on regional climate conditions, building energy efficiency standards, and the thermal insulation requirements of the wall. Typically, professional design teams or engineers recommend thickness based on calculation results.

Question 6

How does XPS foam board differ from EPS foam board?

Accepted Answer

XPS foam board and EPS (Expanded Polystyrene) foam board are both insulation materials, but XPS is more rigid and has a higher compressive strength. EPS is generally more affordable, while XPS has better moisture resistance and a slightly higher R-value.

Question 7

Are there any safety precautions when working with XPS foam boards?

Accepted Answer

When cutting XPS foam boards, it’s essential to wear protective gear, such as safety goggles and a dust mask, to avoid inhaling foam particles. Additionally, follow manufacturer guidelines for safe handling and disposal.

Question 8

Are XPS foam boards resistant to pests and molds?

Accepted Answer

Yes, XPS foam boards are resistant to pests, such as termites, and provide limited nutrient value for mold growth. However, it’s essential to ensure proper installation and address any water leakage issues to prevent mold development.

Question 9

How do I install XPS foam boards?

Accepted Answer

XPS foam boards can be installed using various methods, such as adhesive bonding, mechanical fastening, or using specialized insulation hangers. Always follow the manufacturer’s guidelines and local building codes for proper installation.

Question 10

Do XPS foam boards contribute to indoor air quality issues?

Accepted Answer

XPS foam boards are inert and do not emit volatile organic compounds (VOCs) once installed. However, proper ventilation should still be maintained during and after installation to ensure indoor air quality.
