FAQ About External Wall Insulation
What is the difference between external and internal wall insulation?
External wall insulation is installed on the outside of the wall structure and acts as a thermal barrier against outdoor temperatures, whereas internal wall insulation is applied to interior surfaces and is better for retrofitting without affecting the building’s exterior.
Does external wall insulation reduce noise?
Yes, it provides acoustic insulation by reducing airborne sound transmission through external walls — particularly helpful in urban or high-traffic areas.
Can I install external wall insulation myself?
Some insulation products, like batts or foil wraps, are DIY-friendly for experienced renovators. However, they often require professional installation for optimal performance and sealing.
Will insulation affect the appearance of my walls?
No — insulation like batts or wraps are installed behind cladding or wall linings. The final exterior finish remains unchanged unless you're applying external render systems.
How long does external wall insulation last?
High-quality insulation materials can last 50+ years when properly installed, with minimal maintenance required.
Is external wall insulation suitable for older homes?
Absolutely. Retrofitting insulation can dramatically improve comfort and energy efficiency in older properties with little or no existing thermal protection.
What’s the most eco-friendly insulation option?
Earthwool is made from recycled glass and is formaldehyde-free, making it a popular sustainable choice for eco-conscious homeowners.
How do I compare insulation products?
Focus on R-values, material type, thickness, fire ratings, and acoustic performance. Our team can help with side-by-side comparisons tailored to your build.
