Choosing the right floor insulation for you

Looking for underfloor insulation guidance? You’re in the right place. When it comes to flooring insulation, the goal is simple: create an additional layer beneath your flooring to enhance thermal efficiency. Here’s what you need to consider before buying it:

  • Thermal performance: Opt for materials with low thermal conductivity to prevent heat loss.
  • Durability: Choose dense, elastic materials for long-lasting protection.
  • Installation ease: Select insulation that’s easy to install, whether you’re DIY-ing or hiring help.

Keep your specific goals and flooring type in mind. Whether it’s suspended or concrete floors, picking tailored materials ensures optimal results and satisfaction.

Acoustic Floor Insulation

By dampening impact noises like footsteps and furniture movements, effective floor sound insulation creates a quieter, more peaceful atmosphere between rooms. But that’s not all – it also traps heat and keeps the heating costs down. Various materials are used for acoustic insulation flooring, such as mineral wool, rockwool insulation, acoustic panels, and foam.

Concrete Floor Insulation

Concrete floors, while durable, can feel cold and unwelcoming. Our range of underfloor insulation offers a solution. Adding insulation layers to concrete slabs, along with a moisture-proof membrane, can turn your chilly floors into warm, inviting spaces. Consider rigid floor insulation boards like Celotex PIR to ensure your floor is well-insulated all-year-round.

Suspended Floor Insulation

Insulating wooden floors is a smart move for both comfort and longevity. Suspended floor insulation involves adding a layer between wooden boards and joists, effectively sealing gaps and creating a unified surface that prevents heat loss. For this task, mineral wool floor insulation rolls are an excellent choice. It’s easier to install correctly compared to rigid boards and works well between timbers, accommodating imperfections and timber movement. Consider fibrous insulation materials like sheep’s wool, hemp, fibreglass, or rockwool for the best results.

Comprehensive flooring protection

In addition to insulation, we provide essential products to ensure your flooring is airtight and protected from damp, condensation, and harmful ground gases. Our offerings include:

  • Breather membranes
  • Vapour control layers
  • Damp-proof courses
  • Gas membranes

So, don’t let your property’s heat slip away through uninsulated floors. Insulating a floor isn’t just about saving energy and money, it’s about keeping things comfortable, soundproofed and doing your bit for our planet. After all, nobody likes a cold draught.

Frequently asked questions

Does underfloor insulation cause damp?

Underfloor insulation does not cause damp if it is correctly installed. Ensuring proper ventilation is crucial to prevent any potential moisture buildup, which can otherwise lead to damp issues. Proper installation and good ventilation work together to maintain a dry and comfortable environment.

How do you insulate a concrete floor?

Clean the surface and lay a damp-proof membrane. Place the insulation of your choice, such as rigid foam insulation boards, on top, then add a vapor barrier. Finish with a concrete screed or subfloor before installing your chosen flooring. This process improves energy efficiency and comfort – a win-win!
