Energy Efficiency

Fenster’s aluminium windows are not only about style and beauty, but are designed to significantly reduce the energy wasted when creating a comfortable living environment. (heaters and air conditioners). Double-glazed panels and thermally insulated aluminium frames offer a significant improvement in thermally insulating your home against the summer heat and winter cold. The superior thermal insulation of our systems allows the architect to significantly increase the amount of glass applied to a home’s design.

Caters for large openings

Our systems are designed to cater for very large openings, maximizing the architectural features of glazing. Our assistance in selecting the correct performance glass makes it possible to counteract the solar factor and thermal transmittance challenges associated with such large panels.

High security

Fenster’s double-glazed systems offer improved security levels through double layer safety glass and multipoint locking systems. Glazing beads are inside the home, creating an additional barrier to entry from outside.

Look and feel
