Petralana PETRALIGHT mineral wool, 50 mm / 5 cm

Converting a loft into a bedroom, insulating a façade or creating a quiet study starts with the layers of the building element. Mineral wool helps combine thermal insulation with acoustic and fire-related properties. SteelProfil offers materials for different construction tasks. We can select the wool type for its intended location and the planned surface finish.

Mineral wool’s fibrous structure helps limit heat transfer and absorb sound in a properly constructed assembly. This is useful above living spaces and in walls between rooms. Insulation can be planned when fitting out a study, bedroom or relaxation area. Performance depends on the complete construction, so the choice of cavity insulation should be considered alongside the linings.

In a loft, complete filling of the intended space and continuity of the insulation layer are essential. For a partition wall, connections to the floor above and neighbouring elements also matter. Mineral wool can be matched to these assemblies when a product intended for the application is chosen. Well-planned installation helps make the new rooms comfortable to use later.

Façade boards, roof boards and lightweight cavity insulation differ in their mechanical properties. A layer beneath render has different requirements from flat-roof insulation or a ventilated façade. We help select products with these differences in mind. This allows the insulation to work with the other layers and suit the conditions at its intended location.

The non-combustibility of suitable mineral wool products is an additional consideration in many projects. Requirements for the finished wall or roof must be assessed for the complete solution. Knowing the intended function of the building element when buying helps select a product that suits the design, the required insulation performance and the planned finish.

Our wider material range includes first and second grade, with selected batches available from stock. When supplying mineral wool, we check the variant, condition and intended use. Promotions can offer particularly favourable prices for larger energy-efficiency renovations. This is a useful opportunity to calculate loft insulation together with the other parts of the refurbishment.

Before closing up the construction, it is easier to deal with details around wall plates, corners and service penetrations. On a façade, connections to the plinth and windows can be agreed in advance. These details affect the result just as directly as the choice of board. That is why we discuss the full scope of the work, rather than only the number of packs required for a given area.

Tell us which part of the house or building you want to improve. We will match the wool to that particular job and help calculate the quantity. Material hidden behind render or cladding will influence everyday comfort throughout the life of the rooms. It is worth choosing it while all the layers can still be planned conveniently.
