What insulation does your home need?

The most suitable insulation depends on the age, construction and current condition of your property. In many older homes, the roof and external walls are important areas to check. If the property has a suitable uninsulated cavity wall, cavity wall insulation may be an effective option. If there is no suitable cavity, external wall insulation with render may be more appropriate. The free Nu-Isoleren home check provides an initial indication of which solutions may suit your property.

For a poorly insulated property, the roof is often a logical place to start because roof insulation can significantly reduce heat loss. The external walls can then be assessed for cavity wall insulation or external wall insulation. The ideal order depends on the property itself. Nu-Isoleren uses the home check to assess the roof, walls, façade and possible moisture issues before suggesting the most relevant solutions.

Many homes built from around 1960 onwards have cavity walls, but the construction year alone cannot confirm this with certainty. Wall thickness, brickwork and certain ventilation openings can provide useful indications. Before cavity wall insulation is installed, the cavity should also be checked for sufficient width, cleanliness and technical suitability, and the external façade should be in good condition. Nu-Isoleren can inspect the cavity on site and determine whether EPS bead cavity wall insulation is suitable.

Moisture problems should first be properly diagnosed. Damp patches at the bottom of internal walls may indicate rising damp, while moisture on an external façade can have a different cause. Installing insulation without understanding the source of the moisture is therefore not recommended. Nu-Isoleren also provides rising damp treatment, water-repellent façade treatment and façade services when these are required before or alongside insulation work.

Yes. The Nu-Isoleren online home check is intended as an initial assessment. An on-site inspection can provide a more accurate picture of the technical condition of the property. This is especially important for cavity walls, existing cavity insulation, damaged façades and moisture problems. Nu-Isoleren can then determine which work is technically suitable for the property.

Yes. Several parts of a property can be improved as part of the same renovation. A home may need both roof insulation and cavity wall insulation, for example. If the cavity is unsuitable, external wall insulation with render may be a better option. Façade cleaning, hydrofuge treatment or moisture treatment can also be combined where appropriate. Nu-Isoleren assesses which combination of services best matches the condition of the property.
