Does it matter which way insulation board faces?

Yes, it does matter which way insulation boards face. Many insulation boards have a specific orientation for optimal performance, with one side designed for easier attachment to surfaces or for facing outward for better heat resistance. Always follow the manufacturer's guidelines to ensure proper installation.

What happens if insulation board gets wet?

If insulation boards get wet, they can lose their effectiveness and may even start to degrade. Moisture can cause the material to weaken, leading to potential mold growth or reduced thermal performance. To prevent this, ensure that insulation boards are kept dry during installation and throughout their lifespan.

How long does insulation board last?

Insulation boards typically last for several decades, often around 20-50 years, depending on the type of material used and environmental factors. However, proper installation and maintenance are key to ensuring longevity. Quality insulation boards will offer long-term benefits in energy efficiency.

What are the disadvantages of insulation boards?

Insulation boards offer great thermal efficiency, but there are a few disadvantages. They can be expensive, especially for higher-quality
products. Additionally, insulation boards may not be as durable as other
materials, and they can be susceptible to damage from moisture or physical
impact. Always consider the specific needs of your home before choosing insulation boards.
