Insulate a flat roof

The way why they have a flat roof insulation depends on how your flat roof is constructed. You either have one cold flat roof, an warm flat roof or a inverted flat roof.

1) Cold flat roof

Is the insulation material on the underside of your roof structure? Then you have a cold flat roof. This roof construction is usually used when a warm or inverted flat roof is not possible for technical reasons.

2) Warm flat roof

Is the insulation material located at the top of your roof structure? Then you have a warm flat roof. The advantage of this is that the roof will act as a kind of heat buffer, storing heat during the day and releasing it when it cools down in the evening.

3) Inverted flat roof

With an inverted flat roof, the insulation material is also placed at the top, but with the difference that it is placed directly on the roof covering (e.g. roofing of EPDM) is. An inverted flat roof is usually used for a roof renovation where the current roof covering is still in good condition. The insulation layer is then finished with a covering layer consisting of, for example, tiles, gravel or wood. This way you can create a roof terrace, garden or even parking because there is a very solid "surface".

How to insulate a flat roof?

When insulating a cold flat roof, glass wool is often used, which is placed between the beams of the roof structure or via a suspended ceiling in which the glass wool is applied.

Insulation warm flat roof

The insulation is applied along the outside of the roof structure, so that the insulation material is included in the insulation shell. Roofing material such as EPDM or roofing is placed above this.

Inverted flat roof insulation

The existing roof construction and roof covering (roofing or EPDM) serves as a water-retaining layer. Moisture-resistant polystyrene plates will be placed on top of this. The insulation boards are covered with a material such as gravel or tiles to ensure that the insulation material remains in place properly.
