What is an inverted roof.

Inverted roof designing buildings wiki share your construction industry knowledge. Rigid extruded polystyrene insulation has minimal water absorption due to its closed cell structure. These systems are typically applied in conditions where there is extensive roof traffic or to protect from excessive weather conditions such as multiple hail events. Inverted flat roofs what is an inverted roof.

Inverted roofs typically last longer than traditional ones. Inverted roofs have their waterproofing layer beneath the insulation instead of above it as in other forms of roofing. If water is allowed to pond the roof can be exposed to issues such as greater loads than it was designed to accommodate accumulation of unsightly silt and algae and freeze thaw cycles that place stress on roof coverings. For inverted roofs drainage should be provided at both the water control layer and waterproofing levels.

In this type of construction the principal thermal insulation material is applied on top of the weatherproof covering so that the complete roof construction including roof covering is kept at warm temperatures during the winter months and at moderate temperatures during the summer months. What is an inverted roof. In an inverted roof construction the sika trocal membrane is installed directly to the structural decking usually concrete and the innobond thermal insulation is installed on top of the membrane. An inverted roof is quite simply where the waterproofing layer is installed over the structural deck rather than over the insulation.

The system is also referred to as a protected membrane or upside down. An inverted roof also known sometimes as a protected membrane or pmr roof uses the same materials as a conventional roof but places insulation on the top of the membrane. An inverted roof also referred to as a protected membrane or upside down roof is form of flat roof in which the waterproofing layer is beneath the thermal insulation rather than above it. Inverted roofs have significantly lower maintenance costs than conventional low slope roofs thanks in large part to the insulation in the inverted assembly protecting the roof membrane from mechanical damage during and after construction as well as temperature extremes that cause stress.

Eaglewing is the answer. Inverted roof membrance assembly irma systems are used in applications where the membrane requires protection from site specific hazards.
