The two goals which underpin our passive housing are, firstly, economic: to conserve heat in winter, and coolness in the summer months; and, secondly, to ensure efficiency and low cost of construction. This method of constructing homes within factories is becoming more and more widespread, worldwide. It did not take long for the concept to attract the attention of the local market in South Africa.
A key concept of this industry is the use of double-glazed windows, and, as there has been a recent government decree that all construction in which windows that form more that 15% of each wall must be double-glazed, our houses fit perfectly into this scheme. Helderberg Marine is a leader in the development, the sale and implementation of these U-PVC units. All our composite housing structures include UPVC double-glazed windows and doors, to complete the passive requirements.
