Achieve Superior Efficiency and Savings with Advanced Pipe Insulation

Properly insulating your pipes is a proven way to boost your building's energy efficiency. At Insulation & More we provide a broad range of top-tier pipe insulation products to minimize heat loss, avoid condensation, and protect your plumbing from temperature extremes. Read on to learn how upgrading your pipe insulation can help you realize major energy savings while optimizing your HVAC and plumbing system performance.

Why Insulate Pipes?

Insulating pipes delivers numerous vital benefits:

  • Cut heat loss - Uninsulated pipes waste huge amounts of energy via heat transfer and radiation. Insulation forms a barrier to reduce these heat losses.

  • Prevent condensation - Insulation lessens surface temperature fluctuations that cause water vapor to condense on pipes. Condensation can lead to corrosion and mold.

  • Maintain temperatures - Properly insulated pipes assist in maintaining the temperature of the fluids flowing in the system. This improves performance.

  • Save money - Lessened heat loss equals lower energy bills. Efficiency gains also reduce expenses for system maintenance and repairs.

  • Control noise - Pipe insulation absorbs sound and vibration, resulting in a quieter environment.

  • Safety - Insulation prevents burns by keeping surface temperatures within a safe range.

Which Pipes Should Be Insulated?

All pipes transporting fluids above ambient air temperature should be insulated, including:

  • Hot water heating pipes
  • Chilled water cooling pipes
  • Refrigerant lines
  • Steam and condensate lines
  • Plumbing pipes and drains
  • Radiant floor heating pipes

Even small hot water pipes typically benefit from insulation. Bare pipes waste energy and money while making your building uncomfortable. Outdoor pipe insulation or external pipe lagging is especially important for pipes exposed to the elements.

Types of Pipe Insulation

We offer all the major types of pipe insulation to suit your specific needs:

  • Fiberglass - Fiberglass insulation is composed of fine glass fibers bonded with an adhesive. It provides good insulation, noise reduction, and fire resistance at a low cost.

  • Mineral Wool - Mineral wool insulation is fabricated from molten slag or rocks spun into fibers. It delivers superb fire resistance and temperature performance.

  • Elastomeric Foam - Flexible, cellular rubber insulation that is moisture-resistant and straightforward to install. Provides efficient insulation and noise reduction.

  • Polyethylene Foam - Rigid or flexible plastic foam that insulates well at a very affordable price. Limited temperature range.

  • Phenolic Foam - Rigid foam with extremely low thermal conductivity for superior insulation performance. Often utilized for chilled water and refrigerant lines.

  • Calcium Silicate - A rigid pipe insulation material made from limestone, sand, and cellulose. Offers high-temperature ratings up to 1200°F. Excellent for steam lines.

Our insulation experts can recommend the ideal product for your specific piping systems and requirements, including uv resistant or waterproof options for outdoor pipe lagging. We stock insulation for all standard pipe sizes from 1⁄4” to 36” diameter. Many materials are available in pipe sections, sheets, and rolls.

Ensure Proper Installation

The key to achieving maximum efficiency with any pipe insulation is proper installation:

  • Use the appropriate thickness for the pipe size and application. Insufficient insulation results in excessive heat loss.

  • Seal all seams and joints thoroughly to prevent gaps that enable heat transfer. Use the recommended adhesive, sealant or jacket tape.

  • Pay special attention to valves, elbows and hangers which are common areas for air gaps if not insulated properly.

  • Use vapor-barrier facings when required to prevent moisture issues.

  • Follow manufacturer specifications for cutting, bending, and securing the insulation.

  • Insulate the entire pipe length for maximal performance.

Our team can provide certified installation services or advise your in-house staff. Proper insulation installation is vital for efficiency, safety, and longevity.

Protecting Pipes Exposed to the Elements

For pipes located outdoors or otherwise exposed to the elements, external pipe insulation is essential for protecting against temperature extremes, weather, and physical damage. Insulation & More offers durable and weather-resistant exterior pipe lagging tailored for harsh outdoor environments.

Unlike indoor pipe insulation fitted inside the pipe, external pipe lagging encircles the exterior of the pipe. This robust insulating material is specially engineered to endure UV radiation, moisture, and mechanical damage. The thickness of outdoor lagging exceeds indoor insulation, providing enhanced thermal performance.

We supply exterior pipe insulation solutions for various applications including:

  • Hot and chilled water lines
  • Steam and condensate pipes
  • Plumbing and drainage systems
  • Chemical and gas lines
  • Industrial process piping

Our range of outdoor pipe lagging includes acrylonitrile butadiene rubber (NBR), ethylene propylene diene monomer (EPDM) rubber, and polyolefin foams. These provide excellent resistance to temperature extremes, oxidation, ozone, and weathering.

For the best protection, our team can assess your exterior piping and specify the optimal exterior pipe insulation system. Proper installation is also critical to prevent water ingress. Contact us today to keep your outdoor pipes efficiently insulated against the elements.
