Estimated Pay Back TIme

Estimated pay back time short term : 2-4 years, medium term: 4-6 years, long term : 6-8 years (*)

Medium term

Comments

Wood, PVC or metal frame . When metal frame, il is necessary to plan thermal ruptors to avoid thermal bridges. Considering the climate of Mauritius, it is necessary to favor the reduction of the solar factor by coloured or reflective glazing on the windows directly exposed to the sun.
