What is an inverted roof.
In this issue the investigations team explains how inverted roofs work outlines their benefits warns of a possible cause of problems and describes an unusual investigation.
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.
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.
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.
Eaglewing is the answer.
Rigid extruded polystyrene insulation has minimal water absorption due to its closed cell structure.
What is an inverted roof.
An inverted roof is quite simply where the waterproofing layer is installed over the structural deck rather than over the insulation.
Inverted roofs have their waterproofing layer beneath the insulation instead of above it as in other forms of roofing.

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.
Inverted roofs typically last longer than traditional ones.
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.
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.
Tribal leaders issued a challenge.
Invented by dow in the late 1960 s an inverted roof system uses dupont styrofoam brand xps insulation to protect the membrane helping improve the performance and.
