A Double Exterior Wall Construction is a type of building that is made up of two outer walls, which are joined together at the top. This construction is designed to provide insulation and protection from wind, rain, and sun. The double exterior wall construction is also known as double-wall construction or cavity wall construction.
The double exterior wall construction consists of two parallel walls with an air gap between them. This air gap provides insulation and allows for more effective heating during the winter months. The outer layer of the double exterior wall construction is usually made out of stone or brick while the inner layer is made out of concrete or wood.
Double Exterior Wall Construction can be used to build houses, schools, offices, shops, churches, and other types of buildings where high levels of protection from weather conditions are required.
Double Exterior Wall Construction is a great way to add value to your home. This method of construction involves building two walls that are connected at the top and bottom by a header, which adds strength and stability to your home. If you’re looking for more information on double exterior wall construction, we’ve got you covered.
In this article, we will discuss what exterior wall construction is and how it works. We will also go through some important factors you should consider when choosing between different types of exterior walls.
What is Double Exterior Wall Construction
Double exterior wall construction is a way to build an exterior wall that is more efficient, especially in hot and cold climates. Double exterior walls are constructed using two layers of framing lumber separated by a layer of insulation and covered with rigid foam, plywood, or OSB sheathing. The resulting structure provides a continuous air/vapor barrier versus an air and moisture barrier on each individual floor.
Uses of Double Exterior Wall Construction
- Residential and commercial buildings
- Hotels, hospitals, and schools
- Offices and retail stores
Reasons for Double Exterior Wall Construction
The main reason for using double exterior walls is to save time and money. Double exterior wall construction reduces installation time, which means fewer labor costs. It also reduces material costs by reducing waste and eliminating the need for additional materials such as toe-nailing studs at each course or section of sheeting.
Additionally, double wall construction can be used in areas where there is a high risk of moisture intrusion or condensation and it allows for a continuous air/vapor barrier on both sides of the insulation board.
Steps involved in Double Exterior Wall Construction
The double exterior wall construction method involves the use of two layers of insulated cladding, one on the outside and one on the inside. This method is used for buildings that are designed to be very energy efficient and uses thermal mass tiles or bricks to help store heat from sunlight during the summer months.
This process usually involves four main steps:
- Installing insulation in between two layers of cladding
- Installing vapor barrier between inner and outer layers of cladding
- Installing outer layer (exterior) cladding over top of the vapor barrier layer (interior)
A double wall, or a double wall system, is a concept of how to accomplish the building envelope in a more efficient way. It’s not really two walls at all; it’s just one big cavity with another smaller cavity inside. The space between these two cavities is filled with insulation and air. It’s similar to having an empty box that fits into another empty box that has been cut out of cardboard but with little space between them so no light can get through. A double wall refers to this idea: you are building straight up from the ground (the bottom layer), then cutting out an additional piece from the top layer and placing it on top of your base structure (the second layer). This creates a gap between these two layers which is closed off by adding insulation between them before covering everything up with drywall or other materials like bricks or stone veneer siding exterior wall exterior
A double wall is not really two walls at all.
A double wall is not really two walls at all. The “double wall” concept is actually a term that refers to a continuous air and vapor barrier. In other words, it is one wall with an air and vapor barrier running the length of it instead of taping off areas individually for each room. This reduces labor costs associated with installing multiple layers of drywall by hand and provides improved energy efficiency by reducing heat transfer through the studs when installed on both sides of your house.
The concept of a double/triple wall, depending on the size of the project, allows for a continuous air/vapor barrier versus an air and moisture barrier on each individual floor. In addition to saving time, this method also saves money. The bottom line? A more efficient way to build your envelope.
Materials needed in Double Exterior Wall Construction
- A double wall system requires a continuous air/vapor barrier. This prevents warm interior air from escaping to the outside and also prevents moisture infiltration.
- A double wall system requires a continuous moisture barrier, which is intended to prevent moisture from getting into the home’s living space through cracks in the walls or other openings between the two walls.
- Insulation should be installed between each of these layers, as well as behind any electrical boxes that are mounted on one of the walls
Tools needed for Double Exterior Wall Construction
In order to make your double exterior walls, you will need the following tools:
- Tape measure
- Nails (approx. 3″)
- Level (optional)
- Utility knife
Benefits of Double Exterior Wall Construction
- Reduced installation time, material cost, and labor cost
- Increased energy efficiency
- Reduced air leakage and condensation
Costs of Double Exterior Wall Construction
The costs for double exterior wall construction are similar to the cost of a single exterior wall, but the materials add up quickly. The cost difference between a double exterior wall and a single layer is about $3,000-$4,000 for your average home. Double exterior walls are often recommended when:
- Your building site has poor drainage and you need extra protection from moisture infiltration
- You live in an area that gets cold winters with lots of snow accumulation (the mass of the insulation will help keep heat inside)
Maintenance tips for Double Exterior Wall Construction
- Seal the walls properly to prevent moisture or water leaks.
- Check for signs of mildew and mold.
- Look for any signs of damage to the building structure, such as cracking or bowing, which can indicate there are problems with your home’s foundation.
- Make sure there aren’t any insect infestations in your walls that may lead to structural damage down the road.
Another major benefit of the double/triple wall system is reduced installation time.
Another major benefit of the double/triple wall system is reduced installation time. The reduced total number of seams to seal and penetrations to seal that result from installing a double/triple wall system means that you can install more quickly and efficiently, with fewer labor hours.
This is because there are fewer seams to seal and penetrations to seal in a double/triple wall system than in other systems. A typical installation will involve gluing down the liners (if you’re using them), sealing up all four walls with tape or mastic, then adding insulation layer by layer until each cavity is filled with foam insulation batts or boards that are held on either side by strapping tape and deck screws from above.
The benefits don’t end here. We’ll explore some other advantages later on, but first, let’s look at some examples of how this type of construction works in practice before we go any further.
A double wall system saves time and money
A double wall system reduces installation time, material costs, labor costs, and waste. The airtight barrier conserves energy by reducing the need for heating and cooling systems to work as hard as they do in conventional homes. This can result in significant savings on utility bills over the life of the home. In addition to providing superior thermal performance and energy efficiency, a properly installed double wall system also improves indoor air quality by sealing out allergens and pollution from outside sources.
The double exterior wall construction is a traditional method that has been used for centuries. It’s an incredibly sturdy building technique that can be used in many different ways, depending on the needs of the homeowner. This type of structure could be useful in any area where earthquakes are common or storms cause flooding frequently because it provides extra protection against these natural disasters.
