Hello dear readers of the site, today we will talk about how to make a light hatch on the roof of the house or light shaft, and it is quite difficult to do it. First you need to prepare all the tools and materials that will be needed. As soon as the weather forecast for the next few days will be good, you can start. Try to make an opening and set the window in one day. If you did not have time to do this in a day, then at night, cover the opening with a tarp; Do everything possible to make a roof protected from precipitation over the next day.
Apply the light hatch on the ceiling and drive along the nail in every corner. Then transfer the location of these nails to the rafters using a plumb line. Combine these marks with fat lines.
Blue over the hole and under it on a beam with a size of 5 × 10 cm to strengthen the rafters. After that, mark the corners of the opening, driving into each of them along the nail so that the nails pass through the outer surface of the roof.
Drink the roofing tiles and leaf casing of the roof, guided by the location of the nails. Then mark the location of the strengthening bars.
Saw the rafters located inside the opening, and beat at the top and bottom of the jester opening instead of missing rafters to hold weight.
For the frame, use bars of 5×10 cm size. Bay one beam between the openings to the place where the beams were sawn down.
Cut and put one jamb on both sides of the opening in the ceiling, so that they hold the weight of sawn beams. Then fasten the drywall along the perimeter of the opening.
Around the opening, make a frame of bars of 5×10 cm in size. As soon as the frame is ready, on the inside, coordinate it with drywall, and put insulating material under it.
Ventilation in the attic
The attic needs good ventilation to avoid condensation problems. To do this, you can install either delayers from plywood near the slope of the roof in order to maintain a free -free ventilation hole, or a ventilation reflector that directs air flows past the isolation layers.
