Smart Accordion Technology

Mar 12, 2020 / by SillDry

Windows and doors are a fundamental component of building construction. They are critical to the enjoyment of any building by its occupants, and risk allowing moisture, pests, and other unwanted elements into the building if not properly sealed. Flashing provides a solution to this problem with a thin waterproof barrier to cover gaps and spaces in windows and doorways. However, traditional flashing has a number of shortfalls.

The Problem: Inadequate Flashing Solutions

Traditional flashing consists of a thin layer of weatherproof material such as sheet metal or vinyl, cut to fit around the edges of doors and windows. Although the tried-and-true flashing solutions provide essential protection, builders/contractors face a number of challenges when using these long-established methods and materials.

Size Variation

Doors and windows are constructed in a range of sizes. Traditional flashing materials must be pre-fabricated, so if the door or window size is not within standard size specifications, additional time and money must be spent altering or custom designing appropriate flashing.

Style Differences

Similarly, doors and windows come in a variety of shapes and styles, making it difficult for engineers to ensure adequate flashing products and installation.

Weather Conditions

Weather conditions vary depending on the construction location. Since some materials are more susceptible to expansion and contraction due to temperature fluctuations, engineers are faced with the challenge of finding the right material and flashing design for the local climate.


Once the flashing material is selected, installation can be challenging due to the wide size and style variations. What’s more, traditional flashing materials are thin and can easily be torn, pierced, broken, or bent on a busy construction site.


Engineers must also consider the long-term durability of the flashing installation. The materials selected should withstand decades of use, which can be a problem if the weather conditions change or the flashing is not a perfect fit.

With all of these considerations, it is no surprise that engineers and construction professionals are looking into more versatile flashing innovations.

The Solution: SillDry Smart Accordion Technology®

SillDry Smart Accordion Technology offers a straightforward and zero-waste solution to the problems of traditional flashing. SillDry’s groundbreaking design is durable, versatile, and easy to install, making it more efficient, reliable, and cost-effective than other flashing products on the market.

Engineering Behind the Technology

For over 30 years, SillDry founder Kieran McMahon has long been battling the complications caused by water damage. As an acknowledged and experienced expert on the integration of exterior cladding systems, Kieran had the benefit of a unique perspective from which to consider and develop a more effective flashing solution. His conceptualization became a reality when he joined forces with manufacturing partner The Rodon Group. With Kieran’s flashing expertise and Rodon’s precision manufacturing techniques, the duo could fully realize their design in SillDry.

The innovative accordion design allows for simple installation in windows and doors in a wide range of sizes and styles. It is a one-piece component, which allows for easy installation without the need for onsite assembly. Simply secure one end and stretch SillDry to the other side of the window or door opening before securing the other end.

How It Benefits Your Construction Project

Ease of Installation

SillDry’s one-piece accordion design makes it easy to install without the need for special training or equipment. Since it is easily adjusted to fit most standard openings between 18 inches and 21 feet, it is not necessary to take highly detailed measurements. SillDry’s versatile nature means a perfect fit every time without the potential for human error.

Cost Savings

SillDry’s easy adjustment helps save on labor costs by eliminating the need for special training, detailed measurement, and onsite assembly. This flashing saves time and effort and doesn’t produce any waste material since it does not have to be cut to fit door and window openings. This will help you save money on material that would otherwise be wasted with traditional flashing installation processes.

Time Savings

With its easy-to-install accordion design, SillDry saves time for construction crews and design engineers alike. SillDry can be installed in all weather conditions, thereby reducing overall construction time due to inclement weather.
