About Us

MODEK is a wholly owned subsidiary of the Ampaglas Plastics Group of Companies that specialises in the manufacture and supply of translucent roof sheeting, also known as roof windows. Such sheeting is traditionally used to complement steel, aluminium and fibre cement sheeting where the addition of natural light in roofs and side cladding is necessary and desirable.

MODEK has over 20 years of experience in the manufacture of polycarbonate (PC) and glass-reinforced polyester (GRP) for roofing and side cladding of steel structures, mainly for the purpose of providing and enhancing natural light, but also for other demanding applications.

All MODEK’s products, especially its GRP products, are specifically designed to withstand the harsh South African climatic conditions. In northern Europe and North America PVC is sometimes used for translucent roof sheeting, but due to PVC’s lower heat-distortion threshold it is generally not recommended, nor commonly used, in hot climates such as Africa.

Modek GRP & Polycarbonate roof sheeting is available in all major cities in South Africa, with branches in Cape Town, Johannesburg, Port Elizabeth, East London and Durban, This e-mail address is being protected from spambots. You need JavaScript enabled to view it .
