Inverted Warm Roof Insulation

The inverted roof insulation protects the membrane from extremes of weather such as frost uv exposure and the expansion and contraction that comes about from summer winter temperature cycles.

Inverted warm roof insulation.

Simply defined as a type of roof construction where the waterproofing layer lies beneath the insulation instead of above it as in other forms of roofing inverted roofs ensure that the complete roof construction including roof covering is kept at warm temperatures during winter months and at moderate temperates during the summer months. Rigid extruded polystyrene insulation has minimal water absorption due to its closed cell structure. An inverted roof system is a variation on the warm roof. The insulation can be.

An inverted roof is quite simply where the waterproofing layer is installed over the structural deck rather than over the insulation. These shield the insulation from the effects of uv light and wind uplift. With an inverted warm roof construction put ballast usually graded pebbles or concrete paving slabs on top of the insulation in order to keep the insulation down in the event of wind. The standard design consideration is that the rain falling on the roof filters through the ballast and between the insulation boards until it reaches.

Inverted warm roof variation. Resist water absorption be unaffected by freeze. The inverted roof concept has other benefits.
