For contractors and builders looking for a roofing solution that combines high insulation values, improved performance and sustainability, EPS roofing systems are ideal choices.
Retrofitting and replacing roofing systems offer a key opportunity to reduce a building’s energy consumption. Sustainable retrofitting of roofs with durable, energy-efficient materials helps reduce waste and conserve resources while promoting ecofriendly building practices.
Alleguard provides expanded polystyrene (EPS) insulation for innovative roofing systems that are designed to enhance building efficiency.
ENVIRONMENTAL BENEFITS
There’s an increasing demand for solutions that not only reduce energy consumption and fossil fuel consumption but also minimize the carbon footprint of existing buildings.
EPS, suitable for a wide range of roofing applications, offers a number of benefits including energy efficiency, thermal performance, and versatility.
EPS insulation is becoming more popular in the roofing industry due to its sustainability benefits, notably its recyclability. It is 100 percent recyclable, meaning that offcuts, used, and unused EPS products can be re-grinded and processed into new or other recyclable products, helping to reduce landfill waste.
Unlike other insulation types, EPS does not use harmful blowing agents that contribute to global warming during its manufacturing process. It is environmentally friendly and does not contain: hydrofluorocarbon (HFC), chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC) and formaldehyde.
Another significant advantage of using EPS insulation is its contribution to LEED points on projects.
DURABILITY
EPS insulation has long-term thermal resistance, which means that it maintains its R-value over time, ensuring a building’s energy efficiency.
Based on the EPS rigid board type, EPS insulation products are available at different water vapor permeances. As a result, some EPS insulation types can double as insulation and a vapor barrier when they comply with vapor barrier requirements highlighted in building codes having jurisdictions.
COST-EFFECTIVE
Compared to most other insulation types, EPS insulation is typically less expensive. Because of its sustainable physical properties, such as long-term thermal resistance, it is considered a more cost-effective long-term option.
In geofoam or below grade applications, EPS insulation is a light weight alternative to traditional fills and not only cuts transportation and labour expenses but also simplifies jobsite logistics, as less effort and fewer resources are required to move the material.
Because EPS is a lightweight material, the installation process is also much quicker than other insulation types, which helps to reduce project timelines.
TYPES OF EPS ROOFING INSULATION
EPS is an extremely diverse insulation solution, fabricated to meet multiple roofing and wall system assemblies:
- Fanfold EPS is a nonstructural, rigid insulation board with a laminated facer.
- Tapered EPS roofing insulation can be custom manufactured to meet a project’s specific slope and thickness.
- Poly-faced EPS insulation is a prime choice for insulating commercial roofs, providing additional protection against environmental stresses.
- Flute fill EPS insulation is a custom-cut foam board for retrofitting metal roofs with new roofing systems.
- Holey board EPS products are custom-cut foam boards with pre-cut holes designed for new and retrofit applications.
- Modular stay-in-place formwork uses type 2 close-cell EPS with embedded polypropylene webs for added support during construction.
EPS insulation is the solution of choice for commercial or residential projects, meeting today’s demand for improved performance and energy efficiency.
