Ballasted/IRMA

Next to cold and warm roofs, allnex also provides fully reinforced modified bituminous waterproofing systems for inverted roof membrane assemblies with ballast on top.

This system uses Extruded Polystyrene thermal insulation (XPS) and can be covered by a ballast of pebble stones or concrete pavers on supports.

Roofing Underlayments

Premium performance underlayment, protecting roofs since 1978.

For architects and roofing contractors, roofs are a source of everlasting concern.  70% of all construction litigation is related to leaks, and every leak is a lost opportunity, representing a cost to repair and a corresponding loss of customer trust. Severe weather seems to be the new normal and the risk of damage from ice dams and wind-driven rain are higher than ever.  Underlayments are the last line of defense in a roofing system, and selection of high quality underlayments can be the difference between success and failure.

Protecting the roofs of over 2 million homes, and installed on marquee projects in 25 countries since its introduction in 1978, these high performance solutions provide superior performance and excellent value.

Outperforming the competition, letting contractors shine and keeping families safe and dry.

Warm Roof

Soprema's Xpress Iso is a composite insulation board combining a layer of mineral wool with a polyisocyanurate (PIR) insulation board and a modified bitumen base sheet. All layers are factory-laminated together and come as one layer.  PIR insulation, is already known for its thermal qualities, and when combined with mineral wool insulation, it gets even more effective and durable.  In addition, Xpress Iso significanlty reduces the application time on job sites.

Flexitherm is a graphite enhanced expanded polystyrene insulation which is locally manufactured.  Slopes can be created by cutting the insulation to falls making it easy to achieve the building code requiremens for slopes on a flat roof.
