How to choose the right material
The choice between URSA GLASSWOOL SF 32, URSA GLASSWOOL SF 34 and products Fibrostir is made according to:
type of building
area to be isolated
technical solution in the project
energy efficiency requirements
desired behavior of the facade
In many projects, materials are used complement each other, depending on the role of each area of the building.
Frequently Asked Questions
What role does external insulation play and why is it important?
External insulation reduces heat loss through walls, roof and floors, which means less energy consumption and better indoor comfort. It also protects the building structure from temperature and humidity variations.
What materials can I use for external insulation?
For external insulation are used Fibrostir extruded polystyrene and URSA GLASSWOOL mineral wool SF 32 and SF 34, each suitable for specific areas of the building, depending on technical requirements.
What is the real difference between URSA GLASSWOOL SF 32 and SF 34?
The main difference is thermal performance.
URSA GLASSWOOL SF 32 has a better thermal conductivity (λD 0.032 W/mK) and is chosen when more efficient insulation is sought.
URSA GLASSWOOL SF 34 has a thermal conductivity of 0.034 W/mK and is commonly used in attics, ceilings and other residential areas.
Where is Fibrostir extruded polystyrene recommended?
Fibrostir extruded polystyrene is particularly recommended for areas exposed to moisture and mechanical stress, such as floors, flat roofs or certain special applications, due to its resistance to water and freeze-thaw.
Can I use mineral wool outside?
Yes. URSA GLASSWOOL mineral wool is used for thermal and sound insulation in applications such as facades, pitched roofs and attics, depending on the technical solution chosen in the project.
Are these materials suitable for renovating an old house?
Yes. Both extruded polystyrene and mineral wool are commonly used in renovation and thermal rehabilitation works to improve the energy efficiency of existing buildings.
How do I know which material is right for my home?
The choice of material depends on the area to be insulated, the type of construction and the project requirements. If you're not sure, a technical discussion before you buy can help you avoid wrong solutions or unnecessary costs.
