Radenshield Sisalation Foil

Radenshield Sisalation Foil – Premium Reflective Roof Insulation

Radenshield Sisalation Foil is one of South Africa’s most trusted reflective insulation systems for residential, commercial and industrial roofing. Manufactured by BMI Coverland, Radenshield combines a high-performance reflective aluminium surface with a reinforced membrane that functions as both a radiant heat barrier and a durable roof underlay.

Unlike ordinary roof foil, Radenshield not only reflects radiant heat away from the building but also provides excellent resistance against moisture, dust, wind penetration and condensation. It forms part of a complete roofing system that helps improve indoor comfort while reducing the demand on air-conditioning and heating systems. It is also recommended to assist with compliance with the latest National Building Regulations relating to building energy efficiency (SANS 10400-XA).

Available Radenshield Sisalation Foil Products

Radenshield Single Sided

Radenshield Single Sided is the ideal solution for residential and light commercial roofing where reliable thermal performance and moisture protection are required.

The aluminium reflective layer faces the roof cavity to reflect radiant heat while the reinforced backing provides excellent durability during installation.

Ideal for:

• Residential homes
• Townhouses
• Schools
• Offices
• Small commercial buildings
• Tiled roofs
• Metal roofs

Radenshield Double Sided

Radenshield Double Sided incorporates reflective aluminium on both sides of the membrane, allowing radiant heat to be reflected from either direction.

This provides enhanced thermal performance and makes it particularly suitable for buildings exposed to extreme temperatures.

Ideal for:

• Warehouses
• Factories
• Distribution centres
• Shopping centres
• Large residential developments
• Agricultural buildings

The double-sided construction can contribute to higher overall roof system R-values when used together with bulk insulation such as glasswool or polyester insulation.

Radenshield Ecosential

Radenshield Ecosential is a lightweight, cost-effective double-sided radiant barrier designed for modern residential construction.

It offers excellent heat reflection, moisture resistance and energy efficiency while remaining easy to install and economical for larger housing developments.

Ideal for:

• New residential developments
• Estate housing
• Renovations
• Timber roof construction
• Residential tiled roofs

It reflects up to 97% of radiant heat and provides an effective vapour barrier to help protect roof structures from condensation.

Benefits of Radenshield Sisalation

Installing Radenshield provides numerous advantages:

• Reflects radiant roof heat
• Improves indoor comfort
• Helps reduce electricity costs
• Reduces heat gain during summer
• Reduces heat loss during winter
• Acts as a vapour barrier
• Helps minimise roof condensation
• Protects roof structures against wind-driven dust and moisture
• Lightweight and easy to install
• Excellent tear resistance
• Long service life
• Suitable for tiled and metal roofs
• Compatible with Aerolite, Knauf, Factorylite and other bulk insulation products
• Assists with compliance with South African energy efficiency regulations.

How Radenshield Works

Heat from the sun reaches a roof primarily through radiant energy. Radenshield reflects this radiant heat away before it can enter the roof space.

The membrane also creates an effective moisture barrier that reduces condensation beneath roof coverings while helping protect timber and steel roof structures.

When combined with bulk ceiling insulation, Radenshield creates a complete roofing insulation system that significantly improves overall thermal performance.

Ideal Applications

Radenshield is suitable for:

• Residential homes
• Apartment buildings
• Schools
• Hospitals
• Shopping centres
• Warehouses
• Factories
• Industrial buildings
• Agricultural buildings
• Workshops
• Churches
• Retail stores
• Office complexes
• New developments
• Roof renovations

Installation

Radenshield is installed beneath roof sheeting or roof tiles during construction. Correct installation includes maintaining the recommended air gaps to maximise radiant heat reflection while securely fixing the membrane across rafters or purlins.

Professional installation ensures the membrane performs as both an effective reflective insulation layer and a secondary weather-resistant roof underlay.
