After the attic, the outer walls are the main heat loss zone of a house with little or no insulation. They alone account for 25% of energy losses! Insulating the walls of his house can save up to 25% on his heating bill, but also gain thermal and acoustic comfort.
The components of the Optex system
1. The system consists of semi-rigid glass wool panels, covered with glass veil for thermo-acoustic insulation of the walls from the outside under cladding. The insulation used here belongs to the range Isofaçade d'Isover.
2. Composed of a knock-on hammer, rosettes are used to fix the insulation according to its thickness (from 100 to 220 mm) on the outside wall (Optex rosettes and insulated Isofaçade insulation from Isover).
Implementation of the Optex system
1. Specific brackets are screwed on the face every 60 cm in the width direction and every 1.35 m in the direction of the height.
2. There must be at least 3 brackets regardless of the height of the chevron. The brackets are fixed alternately on the left and right of the rafters.
3. The panels of the first layer of insulation are housed between the brackets and blocked by rosettes.
4. The rosettes to be hammered are hammered. They must be staggered, at least 15 cm from the edge of the insulation and every 83 cm (2 rosettes / m²).
5. The chevron is fixed on the brackets, in front of the first layer of insulation.
6. The second layer of insulation is wedged between the rafters, and fixed, like the first, by rosettes to hit.
7. The cladding (wood or PVC) is fixed on the rafters. A 20 mm thick batten is nailed to each rafter to provide an air gap of 20 mm.
