Condensation and rising energy bills are two of the most common challenges faced by UK homeowners today. With older homes and unpredictable weather, finding the right insulation solution can feel overwhelming. Enter spray cork insulation: an eco-friendly, carbon-negative material that not only combats condensation but also optimises energy efficiency.

In this blog, we’ll explore how spray cork outperforms traditional solutions in addressing these issues, offering a sustainable and cost-effective alternative.
The Problem with Condensation
Condensation occurs when warm, moist air meets cooler surfaces, leading to damp patches, black mould, and even structural damage. This is a common issue in the UK, especially in older homes with poor insulation and ventilation.
Traditional Solutions:
Standard insulation materials often trap moisture, creating a breeding ground for mould and mildew.
Dehumidifiers or ventilation systems help but don’t address the root cause.
How Spray Cork Solves It:
Breathable Material: Cork Spray allows moisture to transpire naturally, preventing condensation buildup.
Seamless and Airtight Application: Unlike traditional materials, spray cork eliminates thermal bridges, ensuring consistent surface temperature and reducing the risk of condensation.
Antifungal Properties: As Kevin McCloud highlighted, cork is naturally antifungal and resists rotting, making it ideal for damp-prone areas.
Tackling Rising Energy Bills
With energy prices soaring, insulating your home effectively has never been more important. Poor insulation leads to heat loss, forcing homeowners to rely on heating systems more frequently, which drives up energy costs.
Traditional Solutions:
Materials like mineral wool or foam insulation can help reduce heat loss but often require thick layers, making them impractical for certain applications.
These materials may also degrade over time, reducing their effectiveness.
How Spray Cork Excels:
High Thermal Performance: With an R-value of 0.058, spray cork provides excellent thermal insulation, keeping your home warmer in winter and cooler in summer.
Thin Application (3mm): Unlike bulky alternatives, VIPEQ Cork Spray can be applied in a thin layer, making it perfect for both internal and external walls.
Seamless Coverage: Its airtight application eliminates thermal bridges, ensuring no heat escapes through gaps.
Spray Cork vs Traditional Insulation: A Quick Comparison
Feature | Spray Cork | Traditional Insulation |
Condensation Control | Breathable, antifungal, seamless | Traps moisture, can lead to mould |
Energy Efficiency | High thermal performance, airtight | Requires thicker layers, less efficient over time |
Application | Thin (3mm), versatile | Bulky, limited to specific areas |
Eco-Friendliness | Carbon-negative, sustainable | Often non-recyclable materials |
Real Results: How Spray Cork Saves Energy and Prevents Condensation
Homeowners across the UK are already experiencing the benefits of spray cork. By addressing condensation at its root and improving thermal efficiency, spray cork reduces reliance on heating systems, leading to noticeable savings on energy bills.
One Spray Cork user shared:"Since applying spray cork to our internal walls, we’ve seen a significant drop in condensation issues. Our home feels warmer, and our energy bills have gone down by 20%!"
