DORAL Diamond provide the modern new generation HYPERTHERMIC® thermal break system with high energy efficiency. They are extremely thermal insulated/thermal breakable tilt & turn windows and balcony doors with energy glazing and a low rate of thermal transmittance (U-factor).
With Diamond Hyperthermic® you save energy and money in the long turn, as you achieve a significant increase in the energy efficiency of your house and a reduction in heating and cooling costs.
All DORAL products, in the initial phase of their development and in their sampling, later on, pass a series of exhaustive tests to certify their properties and their proper operation. They are tested in extreme weather simulators and in special conditions of noise and burglary attempts. From these tests are defined the ratings regarding the thermal insulation, the soundproofing, the watertightness, the resistance to wind and the security of the frames (triplex, etc).
