Alububble Sisalation Foil – Advanced Reflective Bubble Insulation
Beat the Western Cape heat before it enters your home. Alububble Sisalation Foil is a high-performance radiant barrier that combines reflective foil with an insulating air-bubble core to dramatically reduce heat transfer.
Why Alububble Outperforms Standard Sisalation Foil
Unlike traditional sisalation (just foil + paper), Alububble features a layer of sealed polyethene air bubbles. This gives you:
- Extra thermal resistance from the trapped air
- Better durability and tear resistance
- Improved moisture barrier protection
- Superior year-round performance
Available Variants
- Single Sided – Foil on one side, ideal for most residential roofs
- Double-sided – Reflective foil on both sides for maximum performance
- Black / White Options – Aesthetic choices for visible areas
Key Benefits of Alububble Sisalation Foil
- Reflects up to 97% of radiant heat
- Can lower indoor temperatures by 5–10°C in summer
- Keeps buildings warmer in winter by retaining heat
- Excellent moisture and condensation barrier
- Lightweight, flexible and easy to install

How Alububble Works – Radiant Heat Barrier Technology
Up to 97% of summer heat enters your roof as radiant heat. Alububble’s shiny aluminium surface reflects this heat out before it can warm up your ceiling and living space. The bubble core adds an extra layer of trapped air insulation for even better results.
Installation Made Simple
Alububble is lightweight and easy to install over purlins (under roof sheets) or between rafters. We strongly recommend professional installation for best results, especially on large commercial projects.
We supply and professionally install Alububble across the entire Western Cape.
Alububble vs Standard Sisalation Foil
While standard sisalation offers good reflection, Alububble’s bubble core gives it superior thermal performance, better durability, and added structural strength. It’s the smarter, longer-lasting choice for South African conditions.

Frequently Asked Questions – Alububble Sisalation Foil
1. What is Alububble Sisalation Foil?
Alububble is a premium reflective bubble insulation foil. It consists of a layer of air-filled bubbles sandwiched between reflective aluminium foil. Unlike standard sisalation (foil + paper), the bubble core gives it better thermal resistance and durability.
2. How effective is Alububble at blocking heat?
Alububble reflects up to 97% of radiant heat. When installed correctly with an air gap, it can reduce indoor temperatures by 5–10°C in summer and help retain heat in winter.
3. What is the difference between Single Sided and Double Sided Alububble?
Single Sided: Foil on one side – best for most residential roofs.
Double-sided: Foil on both sides – offers maximum heat reflection and is ideal for warehouses, factories, and very hot areas.
4. Is Alububble better than normal Sisalation foil?
Yes. While normal sisalation provides basic reflection, Alububble’s bubble core adds extra insulation, better tear resistance, and improved moisture protection. It performs better in South African conditions.
5. Can Alububble be used under metal roofs?
Absolutely. It is one of the best solutions for metal roofs (IBR, corrugated, etc.). It prevents extreme heat buildup and reduces condensation.
6. Is Alububble suitable for residential homes?
Yes. It works very well in houses, townhouses, and double-storey homes — especially in the Western Cape where summers are hot and winters can be chilly.
7. How do I install Alububble?
Alububble is lightweight and easy to install. It is usually fixed over purlins (under roof sheets) or between rafters. We highly recommend professional installation for best results and proper overlap sealing.
8. Does Alububble help with condensation?
Yes. It acts as an excellent vapour barrier and significantly reduces condensation problems under metal roofs.
9. What sizes are available?
Standard roll size is 1.25m x 40m = 50m². Custom widths and lengths are available on request.
10. Is Alububble fire retardant?
Yes, our Alububble is fire-retardant rated and safe for use in residential and commercial buildings.
11. How long does Alububble last?
When installed correctly, Alububble has a lifespan of 10–15+ years. It is UV-protected and does not easily tear or degrade.
