What is EIFS and why should I consider it?

If you take a drive in any rural area, you’ll notice a majority of homes have a brick exterior. Dolores Ursini, vice-president of DuROCK Alfacing International Ltd., the leading manufacturer of exterior insulation finish systems, talks to us about the benefits of choosing an alternative to brick: Exterior Insulation and Finish Systems (EIFS).  

The DuROCK Pressure-Utilized Compartmented Cavity System (PUCCS), a HOLMES APPROVED system, provides the superior EIFS drainage system. PUCCS has a dual plane of protection against water intrusion protecting the building or home’s substrate, explains Ursini. “Water is a huge problem when it gets behind any cladding – brick, aluminum,” she says.

PUCCS has a patented geometrically defined drainage cavity on the back side of the insulation board with a built-in 10mm air space to ensure proper air filtration and drainage, unlike conventional systems that drain through ribbons of adhesive created by the installer. PUCCS was developed in 2004, but it wasn’t until early this year that the new Ontario Building code, Part 9 – residential construction, requires a geometrically defined drainage cavity board for EIFS, the exact system DuROCK developed years earlier. This system ensures the wall will not rot, grow mould or delaminate.

EIFS offers better energy consumption

Heat loss occurs through many parts of your home, especially through the exterior walls. Unlike other forms of exterior systems, EIFS acts as an energy-efficient thermal blanket for your home. It leaves minimal gaps, meaning there are less places for air to escape, and this can aid in the reduction of your yearly energy consumption.

EIFS will suit any home

EIFS can be made to resemble stone, brick or even siding. There are a variety of colours, textures and designs to choose from, making it easy for you to find one that suits your style and taste.

Here’s a breakdown of how much EIFS costs in comparison to its competitors:

MaterialEstimated cost per square foot Estimated cost for 2,000 square foot home
EIFS$8-$10 (material and installation)$16,000 - $20,000
Bricks$3 to $6 (material only)$6,000 - $12,000
Stone$18 to $20 (material only)$36,000 - $40,000
Cement panels$7 to $10 (material only)$14,000 - $20,000
