ROOFING SYSTEMS

Inverted & Ballasted Roofs

The "Protected For Life" Roof.

Maximum Service Life. Superior Thermal Protection
DESCRIPTION

The Upside-Down Advantage

A conventional roof membrane is exposed to UV, thermal shock, and physical damage. The Inverted Roof System (IRMA) is the intelligent, “upside-down” design. The robust TWIST (SBS) membrane is installed first. The insulation and ballast are then placed on top. This design places the waterproofing membrane in a “perfect,” stable environment, permanently protected from all external threats.

KEY BENEFITS

Protected for Life

The waterproofing membrane is placed beneath insulation and ballast, shielding it from UV, weather, and physical damage.

Maximum Service Life

A stable, protected environment reduces thermal stress and helps the membrane perform for the long term.

Superior Thermal Protection

Insulation above the membrane helps moderate temperature changes and protects against thermal shock.

Built for Demanding Roofs

Ideal for plaza decks, roof terraces, ballasted roofs, and green or blue roof foundations.

Reliable SBS Waterproofing
