Inverted Warm Roof Insulation

The insulation is installed over the waterproof membrane and then protected by pavers planting or loose gravel ballast typically 20 40 mm diameter washed pebbles.

Inverted warm roof insulation. The standard design consideration is that the rain falling on the roof filters through the ballast and between the insulation boards until it reaches. Installed in any weather added to without stripping the waterproof layer easily lifted and replaced re used if the building is altered the insulation for an inverted roof must. Inverted warm roof variation. 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.

An inverted roof system is a variation on the warm roof. 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. 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. 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. The inverted roof concept has other benefits. The insulation can be.
