Ground insulation by 123Isolatie
A cold or damp crawl space can affect comfort and heat loss. We first assess the situation under the home, then choose the insulation method and material that fit best.
From €24,- per m²
A cold or damp crawl space can affect living comfort and heat loss in a home. With ground insulation, the floor of the crawl space is covered with an insulating layer. This can help limit the impact of cold and moisture rising from the ground.
At 123Isolatie we first assess the situation under the home. Based on the crawl space, available height and moisture conditions, we determine which insulation method and material fit best.
Our approach is simple: careful workmanship, efficient insulation, and high-quality materials at a fair price.
The ground under a home can be cold and damp. Especially in homes with a crawl space, this can affect comfort and indoor temperature.
By applying an insulating layer on the floor of the crawl space, the impact of cold and moisture from the ground can be reduced.
Ground insulation can contribute to:
With ground insulation, insulation material is applied evenly across the floor of the crawl space.
The material forms an insulating layer between the cold or damp ground and the home. This can make the crawl space less sensitive to influences from the soil.
An important difference with floor insulation is that ground insulation is applied on the crawl-space floor, not directly against the underside of the floor structure.
A damp crawl space can affect living comfort.
Ground insulation can help limit the impact of ground moisture. When there is serious waterlogging or leakage, it is important to first investigate where the moisture is coming from.
That is why we assess in advance:
At 123Isolatie we work with several types of ground insulation. The best material depends on the crawl space, available height, accessibility and desired insulation value.
Drocom ground insulation is a high-performance insulation applied on the crawl-space floor. At a layer thickness of 30 cm, the Rd-value can reach up to 4.9 m²K/W. That makes Drocom a strong option when a high insulation value is desired.
HR++ insulation beads are lightweight pearls that can be applied on the crawl-space floor. Together they form an insulating layer and can help reduce the impact of a cold, damp ground.
Drowa ground insulation chips are lightweight insulation chips suitable for insulating the crawl-space floor. The chips form an insulating layer and can contribute to a more comfortable crawl space.
There is no single material that is best for every crawl space. The right choice depends on:
01
We review accessibility, height and the overall situation of the crawl space.
02
We look at moisture, water, soil conditions and any existing problems.
03
Based on the situation, we determine which material fits best — for example Drocom ground insulation, HR++ beads or Drowa ground insulation chips.
04
The insulation material is applied evenly across the crawl-space floor at the correct layer thickness.
05
After the work, we check the result and deliver a clean finish.
At 123Isolatie we don’t only look at price — we focus on what technically and practically fits your home best.
Our approach is based on: the right inspection + the right material + the right layer thickness + careful installation.
Whether you choose Drocom ground insulation, HR++ beads or Drowa ground insulation chips, we look at what technically and practically fits your home and crawl space.
A well-insulated crawl space can contribute to more comfort, less impact from cold and moisture, and a more energy-efficient home.
