It is not just the insulation of the attic, walls or the replacement of the windows of the walls of the house that entitle you to a tax credit (ISCED). VELUX roof windows (Confort, Tout Confort and INTEGRA®) with double or triple glazing meet the conditions for obtaining a tax credit for the energy transition thanks to a thermal transmission coefficient (Uw) of 1.5 W / m².K and a solar factor (SW) of 0.36. The 2015 Finance Act provides a tax credit of 30% subject to entrusting the work to a company RGE (Recognized Guarantor of the Environment) under the legal conditions related to this tax assistance (main residence, ceiling at € 8,000 or € 16,000 over 5 years, etc.). The applicable VAT is 5.5% for houses completed more than 2 years ago. The replacement of roof windows also entitles to energy bonuses (related to Energy Savings Certificates) as well as ECO-PTZ and possible ANAH aid.
