At Henley Garden Buildings, we believe that exceptional insulation is the key to creating a garden room that performs beautifully all year round. Our roof, walls and floors are fitted with a high-performance hybris insulation system designed to deliver outstanding thermal efficiency, airtightness and long-term durability — all within a slim, modern construction.
Thermal Core: Hybris Insulation Technology
At the heart of each building is our multi-layer hybris insulation system. This advanced material combines reflective foils, polyolefin foams and polyester wadding into a single high-performance solution. With 20 integrated layers working together, it creates a highly efficient thermal envelope that keeps warmth in during winter and heat out during the summer months.
A Slim, High-Efficiency Insulation System
Despite its impressive performance, our hybris insulation remains slim and unobtrusive. At 100mm thick, it provides excellent U-values comparable to much bulkier insulation methods. This means we can achieve superior thermal retention without sacrificing internal space – ideal for garden rooms where efficiency and comfort matter in equal measure.
Built-In Vapour Control for a Seamless Seal
A continuous, integrated vapour barrier is built directly into the product, dramatically reducing construction complexity and ensuring airtight performance throughout the building. This seamless barrier prevents moisture transfer, helps protect the structure, and maintains a stable internal environment with reduced risk of condensation.
Clean, Safe & Fully Certified
Our hybris insulation is fibre-free, making it more comfortable to work with and safer for indoor air quality. It holds a Class A+ indoor air rating and carries CE, UKCA and Q Mark certifications, demonstrating compliance with strict performance and manufacturing standards. The result is a clean, eco-conscious material that supports healthy, comfortable living spaces.
Durable, Long-Lasting Performance
Designed for longevity, the insulation is lightweight, flexible and highly resistant to sagging or moisture absorption over its lifetime. It maintains its structure and performance year after year, ensuring your garden building continues to feel warm, efficient and inviting – no matter the season.
With our advanced hybris insulation system, every Henley garden building achieves superior thermal performance, structural protection and interior comfort. It’s a modern, dependable solution that turns any garden room into a truly usable, all-year-round space.
