What Is Epdm Rubber Used For In Construction?

Builders like this black, stretchy material because it lasts three decades and survives freezing winters and hot summers. Water leaks are prevented by covering flat roofs with EPDM rubber in construction. It’s glued to the edges of windows and garage doors to seal out rain and wind. It also coats swimming pools to prevent water from leaking out. You’ll see it wrapped around pipes and ducts to keep buildings warm or cool. EPDM doesn’t crack in the sunlight or during heavy storms, like other materials. The next time you see a thick rubber strip around a window, you’ll know that it’s EPDM.

Here is how each of these usages works!

EPDM Rubber Foam: What It Is And How It Works

Have you ever touched a soft, squishy foam mat or a sponge? EPDM rubber foam is similar to that but more durable and designed to endure. So, here’s what it is and why builders love it!

What are the Components of EPDM Rubber Foam?

EPDM foam rubber is made from small pieces of rubber known as ethylene, propylene, and diene (similar to ingredients in a recipe). These are blended and heated until a thick rubber is formed. Finally, a special foaming process incorporates air bubbles, resulting in a lighter, fluffier rubber. It’s like blowing air into melted marshmallows—it’s like that, but for rubber!” That’s why EPDM foam is ideal for wrapping pipes or squeezing into tight spots.

Why Use EPDM Foam as Opposed to Solid Rubber for Builders?

Solid rubber is dense and heavy, while EPDM rubber foam is flexible and lighter. Here’s why builders choose foam:

Flexible: Unlike some kinds of insulation board, foam can stretch around corners or uneven surfaces without ripping.

Thermal Insulation: The microscopic air pockets in EPDM foam contain heat, allowing buildings to remain warm in the winter and cold in the summer.

Cost Efficiency: Because foam uses less rubber material, it’s easier and cheaper to produce and purchase.

For instance, when sealing a roof, EPDM foam compresses better than solid rubber into cracks. It’s like a warm blanket instead of a wooden board!

Properties of EPDM Rubber

EPA rubber foam contains some key properties that make builders opt for EPDM over other materials. Let’s explore what makes it such an effective process for buildings!

Weather Resistance and UV Stability

When you put weather resistance to the test, EPDM rubber foam is a champion! EPDM (ethylene propylene diene monomer) is an exceptionally durable rubber roof that is not susceptible to sun damage like other materials. It doesn’t deteriorate from sunshine, rain, or snow. It is capable of extreme cold (-40°C), and still working in the hot summer weather (up to 120°C (or even 150°C)). Leave a toy out zyear round and in most cases, it would just fall apart on you - except and EPDM foam! This extreme weather protection is due to the unique chemical composition of EPDM. The foam combats UV rays and ozone (air pollution) that would normally cause rubber to crack and break down. This means EPDM foam roofs or seals last for decades without replacement.

Thermal Insulation Performance

The tiny air bubbles trapped in the EPDM rubber foam structure deliver superb thermal insulation. These air pockets prevent the movement of heat through walls, pipes, or roofs. For buildings, it translates to remaining warmer in the winter and cooler in the summer.

Because most types of EPDM foam have a closed-cell structure, heat cannot escape easily. Used around pipes and in walls, EPDM foam saves energy and keeps heating costs down. For instance, when it is wrapped around hot water pipes, it can maintain the heat of the water for a longer period of time, thus conserving energy.

Chemical and Aging Resistance

One of the most amazing things about EPDM rubber foam is how it withstands chemicals and aging. As acids, cleaning products and industrial chemicals are applied, many materials wear away swiftly. However, EPDM foam is resistant to many chemicals that would ruin other materials. The aging properties of EPDM foam are also excellent. Other rubbers may crack and fail after a few years, but EPDM maintains its strength and flexibility for decades. This makes it ideal for areas where replacing materials is costly or difficult such as beneath roofing or surrounding foundations.

Why is EPDM foam great for roofing and waterproofing?

When it comes to the best foam rubber for flat roofs, EPDM foam is always at the top of the list.

Here’s why it is the best material for roofing and waterproofing:

Unbelievable Longevity: The minimum age of EPDM roofing membranes is at least 30 years and the material can potentially last 50 years or more with little or no maintenance

Complete Waterproofing: Being a closed-cell structure, it doesn’t allow water to seep through and keeps buildings dry, even when it pours outside

Simply Applicable: Unlike torch-on membranes that require ignition and release of gas, the EPDM membrane is applied using bonding adhesive, making it a much safer option for installations

Lightweight Product: Weighing roughly 1.25kg/m², EPDM adds very little weight to roof structures while providing an impenetrable defence in return

Root-Proof: Acts as an anti-root barrier making it superior for green roofs and landscape projects as a blight-proofing material as the penetration of plant roots destroys most products

Wide Temperature Range: Since EPDM can withstand extreme temperature ranges - from -40°C to +160°C, it can handle freezing winters and scorching summers

Single-Product Solution: One product can waterproof basements, roofs, podiums and expansion joints

The molecular cross-linked structure of EPDM makes it more durable and flexible than traditional roofing systems.
