This heavy-duty greenhouse bubble insulation is designed to help maintain stable growing conditions by reducing heat loss while still allowing essential natural light to reach plants. Supplied as a 1.5 metre wide by 50 metre roll, it provides an effective thermal barrier for greenhouse glazing during colder months.
Manufactured from strong UV-stabilised polythene with a double-wall bubble structure, this horticultural insulation is built specifically for greenhouse use. Unlike standard packaging bubble wrap, it is designed for prolonged outdoor exposure, offering improved durability and performance across multiple seasons.
Ideal for both domestic gardeners and commercial growers, greenhouse bubble insulation helps create a warmer, more energy-efficient growing environment.
Technical Specifications
· Width: 1.5 metres
· Length: 50 metres per roll
· Material: UV-stabilised polythene
· Bubble Structure: Double-layer thermal air pockets
· Light Transmission: Approx. 70–85%
· Insulation Type: Non-adhesive thermal barrier
The trapped air within the bubble structure acts as an insulating layer, helping reduce drafts and stabilise internal greenhouse temperatures.
Thermal Performance and Benefits
Greenhouse glazing allows heat to escape quickly during cold weather. Installing bubble insulation creates an additional air barrier between the glass and the internal environment, helping retain warmth while maintaining adequate light levels for plant growth.
Key benefits include:
· Helps reduce heating costs during winter
· Maintains more stable internal temperatures
· Protects plants from frost and cold winds
· Allows essential natural light to pass through
· Lightweight and easy to handle
This makes greenhouse bubble insulation a practical solution for extending the growing season and improving plant protection.
Common Applications
This 1.5m x 50m greenhouse bubble roll is suitable for:
· Greenhouse walls and roof insulation
· Conservatory heat retention
· Cold frame lining
· Polytunnels and grow houses
· Temporary plant shelters
Its flexible design allows it to be cut to size for a wide range of horticultural uses.
Installation Guidance
Correct installation improves both insulation performance and longevity.
1. Measure glazing areas and cut insulation to size.
2. Secure using greenhouse clips or specialist bubble fixings.
3. Leave small gaps for ventilation to reduce condensation build-up.
4. Avoid covering automatic vents completely.
The double-wall bubble design helps create a thermal barrier while remaining simple to install without adhesives.
Seasonal Use and Storage
Greenhouse bubble insulation is typically installed before winter to protect plants from falling temperatures. It can remain in place through colder months and be removed or rolled back in spring if full ventilation or maximum light levels are required.
For storage:
· Keep the roll clean and dry.
· Store away from direct sunlight when not in use.
· Roll carefully to avoid creasing.
