As always: thermal insulation in solid walls is child's play, whereas for an all-glass system it is a technical tour de force. Thermal bridging is drastically reduced through an optimised 4-sided composite profile ensuring top thermal values. The solar energy gain through the large area of glass should not be underestimated. That reduces heating costs to a minimum. A fortuitous by-product is the minimum impact on the climate: highly insulating windows and façades reduce CO² emissions.
Josko uses modern composite materials for the best thermal and structural properties. Properties that the traditional aluminium systems have been unable to achieve so far. Compare the total value (Uw – frame + glass) and not just the glass value (Ug). Depending upon the choice of glass suitable for low energy, minimum energy or passive houses.
THERMAL VALUES BY EN STANDARDS
DOUBLE GLAZING UW 1.27* (GLASS UG 1.1)
TRIPLE GLAZING UW 0.76* (GLASS UG 0.6)
*For frames integrated within the building structure, the values develop in accordance with the official test report
Josko do their best to avoid condensation through the use of 4-sided warm frames and triple glazing. Should glass panes in undercooled rooms steam up in spite of this, then the standards compliant condensation channel would protect the internal flooring.
