Tremco Retrofits Headquarters with EIFS

Tremco – one of the leading supplieres of sealants for the EIFS industry – has renovated it’s headquarters with Exterior Insulation Finish Systems. Working with Dryvit’s Outsulation Plus MD EIF System, Tremco was able to re-clad the building without the time, expense and waste associated with removing the old cladding (slate).

The finish chosen was TerraNeo from Dryvit – a texture/colour combination that gives the appearance of granite. It’s a testament to the versatility of EIFS  that it can imitate existing claddings, while providing superior insulation and water management. In a move that shows the respect Tremco has for it’s employees, the exterior appearance of the building was voted on by all the employees working in the building. Nice choice, guys.

Retrofit Your Crumbling Brick with EIFS

Toronto and it’s surrounding area has a large number of brick homes that are reaching the end of their life cycle. While brick is a great siding material by most standards, it tends to fundamentally lack in two primary aspects: design flexibility and insulating ability. As brick-clad homes in Toronto reach their 50-70 year mark they begin to flake off, and the mortar starts coming apart. The combination of newly exposed brick surrounded by weathered brick is not only unsightly, but becomes progressively worse as the seasons roll on. If your brick home is in a state of disrepair, you might want to consider Exterior Insulation Finish Systems (EIFS, like the PUCC-System by DuROCK) as a replacement for the brick.

Isn’t It Difficult To Replace Brick?

The word “replacement” is misleading. Unlike deciding to replace the brick with new brick, EIFS can be applied directly over top of the old brick. This is because EIFS is relatively light weight compared to brick, and made of components that effectively seal and protect the old brick. Being able to save the old brick means that it doesn’t need to be removed – a huge expense in itself. Additionally, brick that is removed must be disposed of in a landfill, creating rubble waste in addition to the fuel required to transport it to the landfill. In short, retrofitting your old brick walls using a system like PUCCS is a superior solution to re-cladding with brick from both a financial and environmental perspective.

It Sounds Too Good To Be True. What’s the catch.

Ok. There is a big, I mean huge… mountain sized… almost insurmountable problem that arises when retrofitting your home with EIFS. You might as well give up before even starting. Seriously.

You’re going to have design your home to your personal tastes.

*gasp*

What a problem to have, right? Unlike traditional brick or vinyl sidings, EIFS is available in a limitless number of combinations of textures, colour and decorative elements like window trims, sills, keystones, columns and cornices. Will you go with the classical Italian look with beautifully decorated windows and doors? How about a sleek, modern-looking design that sticks primarily with straight lines and greys/whites? EIFS can accommodate nearly any architectural style and home design. You’ll be able to flex your creative muscles to figure out what style will suit both you and your neighbourhood.

What Was That About Insulation?

Possibly the biggest benefit that EIFS has over brick is that it insulates your home. That’s not to say that insulation boards can’t be added under a new brick wall, but that requires tearing off the old one with all the associated expenses and environmental impact. EIF-Systems incorporate a layer of insulation that drastically reduces the flow of heat from the inside to outside, or vice-versa, and can be installed directly over existing brick with a cement-based adhesive.

The increased insulation decreases the amount of heat lost from your home in the winter, as well as the heat gained during the summer. This means your furnace and air conditioner needs to work less, consuming less fuel and electricity to keep your home at a comfortable temperature year-round. EIFS again demonstrates it’s ability to reduce your expenses and your impact on the environment.

The only question that remains is: Are you ready to say goodbye to drafty winter nights and wasteful heating bills?

Don’t forget – a standard EIFS installation is not as impact-resistant as brick, but it can be. Wall surfaces next to a driveway or walkways will benefit from additional reinforcing high impact mesh available from EIFS manufacturers like DuROCK. For a small investment, you can protect your walls from unsightly dents and damage that can be costly to repair.

What Type Of Notched Trowel Is Required For The Insulation?

The insulation portion of Exterior Insulation Finish Systems requires that a notched trowel is used in conjunction with the respective manufacturer’s cement adhesive. The insulation is to be installed in vertical ribbons to facilitate drainage and prevent moisture from becoming trapped.

But what sort of notched trowel is to be used exactly? There are dozens (possibly hundreds) of variations, some for tile, some for stucco, and some for EIFS.  Most notched trowels will be 11″ wide x 4.5″ deep, with the blade made from stainless steel. When looking at notched trowels, the following needs to be considered:

  • Type of notch: square, rectangular round, elliptical, triangular
  • Size of notch: ranging from 1/8″ upwards of 1″ (or more)
  • Spacing of notches: ranging again from 1/8″ upwards of 2″ (or more)
  • Right handed versus left handed
  • Handle material and shape

While each EIFS manufacturer has their own specifications, the “standard” seems to be: 1/2″ deep x 1/2″ wide square-notches with 2″ spacing. Handles (shape and material) and which hand (left vs. right) is usually left up to the contractor, to decide which is more comfortable.

Don’t forget that there are inside corner trowels, outside corner trowels, various finish coat floats and a wide assortment of handles.

Trim, Molding and Wall Decor

EIFS is a highly customizable siding from an aesthetic point of view – with the ability to select from a broad range of colors (unlimited if you consider the matching capabilities), a wide range of textures and an unlimited combination of window trim and moldings. Decoramould products are designed specifically for the EIFS industry – made from the same products as the EIFS wall itself, their trim and moldings are biologically inert and can not rot, warp or become infested like traditional wood trim products. When looking for a maintenance-free trim that will last more than 10 years without needing to be replaced, Decoramould is the preferred choice.

Window Trim

Designed in shapes that are attractive around a window, window trim frames a window, making it appear larger and more pronounced. Trims are typically installed along the sides and top of a window, with a window sill for the bottom of the window in a similar shape to the trim.

Keystones

Decoramould keystones or polyurethane keystones are commonly installed in the top center of a window. While polyurethane keystones are more ornate than regular keystones, simply adding them to a window will distinguish your windows from similar plain houses.

Quoins

Quoins are installed on the corner of homes, accenting the very outside dimensions of the home. They provide a visual sensation of sturdiness, making a home appear well-built. Quoins can be installed during the construction or renovation process, or just as easily afterwards.

Trim Colors

There are a number of style options when it comes to deciding what color your exterior trim should be. The majority of the time, a trim color is chosen that is a few shades darker or lighter than the color of the wall itself. It’s a safe bet that the two colors will mesh well together, and creates a very nice accenting effect.

Trim Texture

Typically, the texture of a trim resembles that of concrete. If they are painted with an exterior-grade masonry paint or with an EIFS-manufacturer paint (with sand texture), the texture of the molding itself will show through. On flat pieces of trim, a skilled EIFS applicator can actually apply a trowel-applied texture that can match a wall.

Spraying the EIFS finish coat provides a texture that is very bumpy and resembles stone more than a precast product. It should be noted that spray-applied finishes don’t tend to last as long as painted or trowel-applied finishes.

The overall effect of having a trim with a different color and texture is very elegant.

EIFS Synonyms and Spellings

There are many synonyms and spellings for EIFS, due in part to varying pronunciations on the job site by contractors and skilled tradesmen. Officially, the spelling “Exterior Insulation Finish Systems” is used by the governing body in Canada (the EIFS Council of Canada) and “Exterior Insulation and Finish Systems” is used by the governing body in the USA (the EIFS Industry Members Association).

Other variations include:

  • Exterior Insulation Finish System (EIFS)
  • Exterior Insulation Finishing Systems (EIFS)
  • Exterior Insulated Finish Systems (EIFS)
  • Exterior Insulated Finishing Systems (EIFS)
  • Exterior Finish and Insulation Systems (EFIS)
  • Exterior Finish and Insulating Systems (EFIS)

What colors is EIFS available in?

EIFS manufacturers typically have color chart that lists a couple dozen of their standard/common colors ranging from earthy beiges to vibrant blues. Most manufacturers will have the ability to custom match an existing color, whether it be a paint sample from the hardware store or the blue of your favorite car. This makes the choices for coloring your home literally limitless.

When matching a specific color, the best practice is to get an 8″x8″ (or similar) size sample made up from the manufacturer to ensure that it is what you are looking for. The texture of EIFS finish coats will slightly change the perceived color because of the miniscule shadows cast by the finish coat aggregates.
