ATTIC VENTILATION PROCESS
LEARN ABOUT OUR PROCESS & SEE WHY WE ARE CALGARY'S ATTIC VENTILATION EXPERTS
Attic insulation is aimed at sealing the air in the house, and attic ventilation ensures that the attic is well ventilated. Whether you are adding to what already exists or starting from scratch, 4 Weather Insulation & Roofing can offer professional assistance with the entire attic ventilation process. Our attic ventilation process is as follows:
1. We chat with you and discuss your concerns and needs. We follow this up by sending an expert to personally assess your home and come up with appropriate solutions for you.
2. Before we commence insulation, we take our time to air seal the ceiling plane, ensuring that heat is kept in your house. To do this, we’ll plug any holes – such as electrical wiring and plumbing induced gaps – in the attic with foam or caulk. Next, we put damning around your chimney and air heaters to make sure that heat is retained. This twin action preserves the heat in your home, keeping you warm and saving you a lot of money.
3. Venting your roof prevents the potential damages moisture can induce in your house. As we already find ourselves in your space, we take the time to evaluate and install a proper attic ventilation system for your roof space.
4. Now it’s time for the insulation itself. There are various materials that can be employed in attic insulation – blown cellulose, spray foam, rockwool, blown fiberglass, rigid foam, or fiberglass batts. Whichever the case, we will insulate your attic with between 13 and 18 inches of insulation. Here’s a basic rundown of these materials:
- Blown cellulose: this is a durable, environmentally friendly, and non-toxic material that is made of recycled newspaper with borate salts.
- Spray foam: this is a two component foam with a high insulating value. Spray foam expands to fill openings, making it resistant to air and water. However, it is unhealthy to breath during curing. When installed in a living space, it must be covered with a fire rated barrier.
- Rockwool: this is basically molten rock or basalt spun into fine strands. It is fairly expensive and is made available in bats.
- Blown fiberglass: this is molten silica blown into fine strands and held together by a binder. They are inexpensive, while providing the same value as blown cellulose.
- Rigid foam: this type of spray foam is cured at the factory into sheets with a range of coverings. It can be fitted into both beams and walls.
- Fiberglass batts: similar to blown products, they are a less effective insulation material which are best used when insulation is likely to be removed in the near future.
5. With the attic insulated, we turn our attention to the attic hatch. To keep insulation from falling off, we dam around the hatch and install a weather stripping kit. A rubber gasket or silicone is fitted into the spot where the hatch and the house connect to make an airtight seal.
Understanding the attic ventilation process is an integral step to ensuring that your home is warm in the winter and cool in the summer. If you want professional service that is performed right, make sure to contact us at 4 Weather Ventilation today.
