When tackling noise issues in your property, choosing the right soundproofing solution can feel overwhelming. At DIY Building Supplies, we've guided countless homeowners through their acoustic insulation projects, from simple bedroom upgrades to comprehensive whole-house soundproofing installations across the UK. Drawing from years of experience supplying quality materials from our Nottingham base, we understand exactly when this flexible insulation becomes your ideal solution for noise control.
Understanding Acoustic Insulation
Before exploring specific applications, it's worth understanding what makes this soundproofing material so versatile. Manufactured from glass mineral wool by trusted UK brands like Knauf, Rockwool, and Isover, these flexible insulation products have been specifically engineered to absorb sound waves and reduce noise transmission between spaces.
The science behind effective soundproofing is straightforward. When sound waves travel through your home, they create vibrations that pass through walls, floors, and ceilings. This flexible mineral wool insulation works by absorbing those sound waves within its fibrous structure, significantly reducing the intensity of noise that passes through. This absorption capability, combined with the material's ability to dampen vibrations, makes it particularly effective for controlling airborne sounds like voices, music, and television noise.
Modern products feature densities exceeding 10kg/m³, which is essential for meeting the absorption requirements outlined in UK Building Regulations Part E. This carefully calibrated density allows the material to trap sound waves effectively whilst remaining lightweight enough for straightforward installation. The non-combustible nature of glass mineral wool also provides peace of mind, achieving the highest Euroclass A1 fire safety rating.
Creating New Partition Walls
If you're planning to divide a larger space into separate rooms, soundproofing insulation should be at the top of your materials list. Whether you're converting a bedroom into an ensuite and dressing room, creating a home office from unused space, or dividing a basement into multiple functional areas, partition walls demand effective noise control from the outset.
Installing this insulation between timber or metal stud partitions during construction provides significantly better noise control than attempting retrofitted solutions later. The flexible nature allows it to friction-fit snugly between studs at standard 400mm or 600mm spacings, eliminating gaps that could compromise performance. At DIY Building Supplies, we've seen this approach transform countless home office conversions and bedroom divisions.
For standard internal walls where moderate noise reduction suffices, 50mm thickness provides excellent performance whilst maintaining wall thickness within reasonable limits. However, when separating spaces with higher noise levels, such as home cinema rooms or music practice areas, upgrading to 100mm thickness delivers substantially improved sound absorption. Our team can help you select the appropriate specification based on your specific requirements and budget.
Tackling Floor Noise in Multi-Storey Homes
One of the most common soundproofing challenges involves noise transmission between floors. The combination of footsteps, furniture movement, and general activity on upper floors creates impact noise that travels readily through timber joists to rooms below. This flexible insulation provides an effective solution for this persistent problem that we encounter regularly at DIY Building Supplies.
When installed between floor joists before laying floorboards or chipboard, the material absorbs both airborne sound and reduces the transmission of impact noise. This proves particularly valuable in homes where bedrooms sit beneath living areas, or where home offices require quiet working conditions beneath active family spaces.
For properties where you're addressing noise from above, this insulation works best when combined with a comprehensive approach. Installing the material between floor joists provides the foundation for noise control, but achieving optimal results often involves pairing this with acoustic-grade plasterboard on the ceiling below. We've helped numerous families tackle this challenge, typically recommending 100mm thickness for maximum noise reduction in these high-activity areas.
Retrofit Solutions for Existing Properties
Not every soundproofing project involves new construction. Many homeowners contact DIY Building Supplies seeking solutions for existing structures where noise has become problematic. This flexible insulation offers particular advantages in certain retrofit situations.
Accessible Loft Spaces
If noise from your roof or neighbouring properties penetrates through your loft space into bedrooms below, adding soundproofing insulation provides a practical solution. The material's flexibility allows it to be laid between loft joists or draped over existing insulation, adding a sound-absorbing layer that reduces noise transmission.
This application proves especially valuable for properties near busy roads, under flight paths, or in areas where external noise creates disturbance. When working in loft spaces, products like Superglass Multi feature perforated formats that tear cleanly to fit between standard joist spacings, minimising cutting and waste whilst ensuring complete coverage.
Behind Plasterboard Linings
Properties with cavity walls or areas requiring improved soundproofing can benefit from installation behind new plasterboard linings. This approach, often called dry-lining, involves creating a new internal wall surface with the insulation filling the cavity behind. The flexible nature makes it ideal for this application, particularly where walls feature pipes, cables, or uneven surfaces that rigid insulation boards would struggle to accommodate.
At DIY Building Supplies, we stock products specifically designed for dry-lining applications, with thickness options that balance performance against the internal space you're willing to sacrifice. Typically, 25mm to 50mm products work well in these scenarios, providing meaningful noise reduction without excessive wall thickness.
When Alternative Solutions Work Better
Whilst this insulation offers remarkable versatility, understanding its limitations helps ensure you select the right material for every application. Our experience at DIY Building Supplies has taught us that certain situations call for different approaches.
For extremely high-noise environments—such as rooms adjacent to commercial kitchens, workshops with heavy machinery, or spaces requiring professional studio-grade soundproofing—this flexible material alone may not provide sufficient noise reduction. These scenarios often benefit from denser acoustic slabs or specialised high-mass barriers that block rather than simply absorb sound.
Areas where insulation will experience continuous compression, such as beneath concrete floor screeds or under heavy permanent structures, require more rigid insulation products. The flexibility that makes this material advantageous for friction-fitting applications becomes a disadvantage when it might compress over time, reducing thickness and consequently performance.
Real-World Applications We've Supported
The Home Office Conversion
Remote working demands effective sound control. Installing 50mm insulation from Knauf or Isover in partition walls ensures conference calls remain private whilst preventing household noise from disrupting your working day. Consider installation in both walls and the ceiling if rooms above generate noise, creating a professional working environment within your home.
Family Homes with Young Children
Families often struggle with noise travelling through their homes, particularly where children's bedrooms sit above living spaces. We've helped numerous families across the UK tackle this challenge with soundproofing solutions that transform daily living, reducing stress and improving sleep quality for all family members.
Period Property Renovations
Older properties frequently feature limited original soundproofing. The flexibility of this material makes it particularly suitable for period homes where wall structures may be irregular or require working around existing architectural features. At DIY Building Supplies, we've supplied countless period property renovations where maintaining character whilst adding modern comfort was essential.
Selecting the Right Specification
Once you've determined that this insulation suits your application, selecting the appropriate product specification ensures optimal performance. Several factors influence this decision, and our team can guide you through each consideration.
Thickness options range from 25mm to 100mm, with each suited to different applications. For dry-lining applications and space-restricted areas, 25mm provides effective noise reduction. Standard partition walls typically benefit from 50mm thickness, whilst 100mm delivers maximum noise reduction for high-activity areas or demanding acoustic requirements.
Most products come in standard 1200mm widths, with some manufacturers offering pre-split formats at 600mm or 400mm widths to match common stud spacings. This reduces waste and simplifies installation. Our team at DIY Building Supplies can assist with quantity calculations, ensuring your order arrives complete and ready for installation.
Building Regulations Compliance
Part E of the Building Regulations sets specific requirements for sound insulation. At DIY Building Supplies, we recommend products with densities exceeding 10kg/m³ for projects where compliance matters. Manufacturers like Knauf and Isover specifically design their products to meet or exceed Part E requirements when installed according to technical guidelines.
Remember that this insulation functions as one component within a complete system, working alongside appropriate wall structures and finishes. When installing in loft spaces, never block ventilation pathways or restrict air movement in areas prone to condensation. Our technical team can provide guidance on achieving effective soundproofing whilst preserving essential ventilation.
