||EIFS - Edgewrapping and Backwrapping
Edge wrapping and back wrapping are two ways of terminating the edges of Exterior Insulating Finishing Systems. Edge wrapping and back wrapping both utilize the EIFS materials that are already on hand, instead of incorporating additional pieces like the use of embedded trim does. In Canada, edge wrapping and back wrapping are far more common, whereas in Europe embedded trim is the edge termination method of choice because their base coats are nearly twice as thick as those used in Canada, allowing for a better grip that holds the embedded trim in place more securely.
||EIFS - Flashing versus embedded trim
With regards to Exterior Insulation Finishing Systems, embedded trim is "embedded" or bonded into the coatings of EIFS, whereas flashing is a loose material that is placed against EIFS coatings.
||EIFS - Floor line joints
A situation may arise where a designer, home or building owner doesn't want to use joints at floor lines for aesthetic reasons.
Some materials expand when faced with temperature variations, and wood is one of them. When two floors meet on the exterior wall of a building or home with wood framing, floor joints are usually installed to prevent the expanding between floors and subsequent cracking of the Exterior Insulation Finishing System lamina. Often, floor line joints are necessary but there are certain times you may be able to avoid using them or be able to utilize other methods.
||EIFS - Attaching gypsum-based sheathings
In Canada, EIFS is normally applied to a substrate made of gypsum-based sheathing, which then must be fastened to the supporting framing. The fasteners and methods used to apply external sheathing differ significantly from those used to install drywall on the interior walls, and are an important element in the structural integrity of the whole wall.
||Design features of EIFS - aesthetic reveals
The fact that Exterior Insulating Finishing Systems are largely comprised of foam bodes well for them with regards to their endless design possibilities. This foam can be cut, grooved or altered to create features on any EIFS wall, and one of these features is the aesthetic reveal or aesthetic joint. The former term is preferable, as the latter term implies it is a joint. While resembling a joint, aesthetic reveals are not functioning joints.
||Using cast stone with EIFS
The impact resistance of Exterior Insulating Finishing Systems is something that has evolved to significant improvement since it first became widely used in Ontario. There are several ways to increase the impact resistance of EIFS easily, but not all are plausible for every given project. Using a heavier weight of reinforcing fiberglass mesh is one option, as is using a thicker base coat to strengthen the EIFS wall from the inside out. However, there are always some situations that will arise where certain more vulnerable areas of the EIFS need to be protected only, and using heavier materials all over the entire wall isn't warranted or necessary.
||Backwrapping, Edgewrapping and Terminating EIFS
No matter what type of wall-cladding is used on a home or building, it will stop and start at some point on the wall. These termination points are where water intrusion, if it's at all possible, may occur. Extra precaution must be taken at these points to ensure that no water intrusion takes place, as this is typically what alludes to the common misconception that Exterior Insulating Finishing Systems are a form of wall cladding that is prone to leaking.
||Why EIFS are not a do-it-yourself project
There are often a small group of individuals who believe they're much handier than normal and can install any material or undertake any project head-on by themselves. On the other hand, they may have a very handy relative who they believe can help them out with their exterior installation. A much more dangerous group would be corporations or organizations that believe EIFS is very simple to put together, and marketing it to homeowners as a do-it-yourself project would make them a lot of money.
||The EIFS industry - past, present and future
Despite EIFS being a quality product, as with any industry that relies on one product for its livelihood, there may always be a slight caution when it comes to using it. The undeserved reputation EIFS has garnered itself doesn't help, and some may feel that it's too much of a risk to bother with EIFS at all.
||EIFS and Flashing
Flashings aren't an Exterior Insulation Finishing Systems component, nor are they made by the same manufacturer, but they are an essential part of many EIFS walls, especially where the EIFS meets other installations like windows and doors.
Flashings are necessary to redirect any water that comes in contact with the EIFS and ensure that it is carried away from the wall safely, and flashings are required by most building codes. Moisture intrusion is a threat to any wall cladding system, and flashings are not unique to EIFS. Various tapes and other sealants can also be used to prevent water intrusion issues with EIFS.
||Applications EIFS are not well suited for
As with any construction material, Exterior Insulation Finishing Systems may find themselves being used in ways they weren't meant for, either improperly installed or in completely inappropriate situations. Even the most knowledgeable or skilled craftsman may not be able to pull off these particular applications effectively, and attempting to do so will cause problems later on.
||Why we have two types of EIFS barrier and drainage
In the mid-1990s, Exterior Insulation Finishing Systems were frequently in the news because of significant moisture-related issues that were affecting homes in the United States. While these issues were primarily concentrated in North Carolina, EIFS other areas and climates are not unsusceptible to this issue. Because of water intrusion, the wood-based materials found in the supporting walls would begin to rot and give way to serious mould infestations. Similar issues are now being found with a series of condominium projects in Alberta, which are also being heavily reported on.
||Attaching components to EIFS
Exterior Insulating Finishing Systems are not supporting materials. Yes, they are effectively resistant and can withstand the elements, some inclement weather as well as wind and rain, but they are not designed to have things hanging off of them or nailed into them. That said, there are many situations that can arise where something seemingly and absolutely must be incorporated into the EIFS in such a fashion. However, many problems that tend to get blamed on the EIFS itself can often be truly attributed to other sources, a main one being things attached to the EIFS. It is important, that when attaching anything to EIFS, certain precautions are taken and that all avenues are looked into first.
||Common misconceptions about reinforcing fiberglass mesh
Fiberglass is composed of tiny glass fibers that are produced when glass that is heated and extruded into extremely thin threads, a process that’s been used for many centuries. The application of this production into the material that we know today as fiberglass began in the late 1930s.
||What does a downturned economy mean for EIFS
It's not news to anyone that in recent times the economy has been quite volatile. Many people have lost their jobs, those who never had to before are budgeting their finances, industries are failing, and nearly all sectors have been hit hard.
||Water resistive barriers and drainage EIFS
Often building codes may specify that for whatever reason, drainage Exterior Insulation Finishing Systems must be used, especially is the substrate is vulnerable to moisture. This will often necessitate a protective coating between the EIFS drainage components and the substrate, called a water resistive barrier coating. The lamina of EIFS is already applied in a manner that allows water to run off of the exterior and does not require preexisting drainage capabilities, and therefore does not require WRBs, but when drainage components are implemented, WRBs should be incorporated and may be demanded by building codes in the area.
||Water and EIFS Water Vapour
Water and Exterior Insulation Finishing Systems have a tumultuous relationship, one that is very much responsible for bringing an unfairly deserved reputation and a plethora of bad press to EIFS. Most of this concern is centered around water in its most basic form, liquid. Liquid water is not a large problem for EIFS as it can leave the materials quite easily, either by running off the surface or through drainage components.
||The ins and outs of EIFS joint placement
Joints serve as an interface between components and are used in Exterior Insulation Finishing Systems between EIFS where it is laid adjacent to more EIFS, as well as where EIFS meets other materials.
||The component that makes EIFS the foam
One major material that makes Exterior Insulating Finishing Systems different from all other wall cladding systems is the insulating foam. In fact, the foam is what makes it an EIFS, and without it it would be merely a wall coating.
||Solving the issue of leaks and EIFS with primers
A situation arising in which the Exterior Insulation Finishing System is actually leaking itself is very rare. Leaks or moisture intrusion are usually due to other issues like weak joints, improper installation below and near grade or the EIFS' proximity to openings such as windows.
||Impact resistance of EIFS walls
Building and home walls generally do not require much impact resistance. There are few situations where an object is actually going to hurl itself at an exterior wall with enough force to damage it.
||EIFS: The legal fine print, or covering your own...
Exterior Insulation Finishing Systems are a great product, and if this wasn’t common knowledge throughout the industry, it would not be so widely used if all EIFS brought to those who installed EIFS were headaches, frustration and legal problems.
||Aesthetic Problems with EIFS
Sometimes, your kids will decide to wait until the new Exterior Insulation Finishing System is freshly clad before carelessly shooting an official NHL hockey puck directly at it, leaving a dent. The EIFS is then patched up and back to full-strength, but something is “off” where the original dent was. Is it the light? The colour? The texture? Killing the future NHLer will not fix your problems, however.
||Ontario bird species might like EIFS as much as you do
bird species seem to have a blast digging up Exterior Insulation Finishing
Systems and taking residence in them. The EIFS provides them with a
warm, soft home to live and set up shop in, building a nest in which
to raise their own families right next to yours. Some of these birds
are even migratory, which means once they’ve found a suitable home
for the warmer months, they’ll be sure to make repeat visits to their
favourite summer destination spot - the inside of your exterior wall.
||In case of fire: Exterior Insulation Finishing Systems in Ontario
Some types of buildings, especially public buildings such as hospitals, schools or corporate offices, require more fire proofing than normal within the building envelope. Exterior Insulating Finishing Systems do not offer additional fire proofing, however extensive testing has proven that EIFS does not detract whatsoever from the fire proofing of a preexisting wall that already meets necessary fire codes. In short, the fire resistance that is required by local building codes must be met by the supporting wall, and applying EIFS will not reduce the abilities of any fire proofing that is already in place.
||The installation of EIFS near grade
Damaging problems can arise when EIFS are installed below grade, or below the ground, but what about when they're only installed near grade? Buildings tend to begin at the ground, and therefore the EIFS might too, depending on design or aesthetic specifications.
Expanded polystyrene foam (EPS) has melting point of 165°F, or about 73°C. When the foam melts, it may not necessarily liquify (although if faced with direct heat like that of a fire it will), but it tends to shrink, which will cause it to pull away from the lamina, which consists of the base coat, the reinforcing fiberglass mesh and the finishing top coat. If the foam pulls away from the lamina enough, the lamina can end up loose, hanging or falling off completely.
||EIFS vs. Stucco and switching over
The expanded polystyrene foam (EPS) used in EIFS is not noncombustible, while stucco is noncombustible. It is important to note however, that incorporating EIFS onto a wall that is already up to necessary fire codes does not detract from the supporting wall's preexisting fire resistance in any way.
||Repairing water-damaged EIFS without complete removal
In many cases, performing sufficient repairs on Exterior Insulation Finishing Systems may mean to some who are uninformed that they must be completely removed and redone. However, this does not have to be the case, and a bit of pre-existing knowledge can help you in avoiding these costly and time-consuming situations.
||What can I get away with - Modifying EIFS
Exterior Insulating Finishing Systems are great multitaskers, and there’s a lot they can do for you. They insulate, are energy-efficient and offer a high aesthetic appeal. That said, these qualities may not be enough for some, and there’s many people who wonder if they can get away with modifying EIFS in some way (or if they can create a "hybrid system"), but still not alter their functionality or structural integrity. This article will shed light on key issues that should be taken into consideration before attempting anything of the sort.
||An exercise in Canadian EIFS preparedness
After a decent amount of time has passed since the installation of EIFS on a home or building, minor repairs may need to be made, performance may need to be assessed as well as the arising of other enquiries that will necessitate the removal of a small portion of the EIFS to see what’s going on internally. Obviously, once this portion has been removed, it should be fixed up again. Having continuous access to the supplies needed for this job can be tricky unless you have a preexisting kit on hand, ready for the job when the time calls for doing these minor patch-ups.
