If you’ve got some spare time on your hands you could save yourself hundreds of pounds per year and add value to your house by lifting your floorboards (or removing your ceiling) and installing insulation.
Installing insulation between your ceiling and floor boards can help improve energy efficiency and reduce noise transmission between different levels of your home. Here’s a step-by-step guide to help you install insulation in this area:
Materials and Tools You’ll Need:
- Insulation material (such as fiberglass batts, mineral wool, or foam board)
- Utility knife
- Measuring tape
- Safety goggles
- Dust mask
- Gloves
- Long-sleeved shirt and pants
- Staple gun or insulation supports (to hold the insulation in place)
- Caulk or foam sealant (for sealing gaps and cracks)
- Protective covering for the floor and furniture (to catch falling debris)
Steps:
**1. ** Safety Precautions:
- Put on your safety gear: goggles, dust mask, and gloves.
- Cover the floor and furniture in the area where you’ll be working to catch any debris.
**2. ** Measure and Cut:
- Measure the distance between the ceiling joists or floor joists.
- Use a utility knife to cut the insulation material to fit the measured space. Make sure it fits snugly without any gaps.
**3. ** Install the Insulation:
- Insert the insulation material between the ceiling or floor joists. If you’re using fiberglass batts, be careful not to compress them too much, as this reduces their effectiveness.
- Use a staple gun or insulation supports to hold the insulation in place. Staple the facing of the insulation to the sides of the joists to prevent it from sagging over time.
**4. ** Seal Gaps and Cracks:
- Inspect the area for any gaps or cracks around pipes, electrical wiring, or other penetrations in the ceiling or floor.
- Use caulk or foam sealant to seal these gaps and cracks. This helps in preventing air leakage, which can significantly impact the insulation’s effectiveness.
**5. ** Safety Check:
- Double-check for any exposed wires or other potential hazards that the insulation might cover. Ensure everything is properly insulated and sealed.
**6. ** Clean Up:
- Clean up the area, removing any excess insulation material or debris.
**7. ** Dispose of Waste:
- Dispose of any waste material properly, following local regulations.
Tips:
- Safety First: Always wear appropriate safety gear, especially when dealing with insulation materials, as they can irritate the skin and respiratory system.
- Proper Fit: Ensure the insulation fits tightly between the joists without any gaps or spaces. This ensures maximum effectiveness.
- Sealing: Properly sealing gaps and cracks is crucial for maintaining the insulation’s efficiency. Air leaks can significantly reduce the insulation’s effectiveness.
If you’re unsure about any step of the process, or if you’re dealing with a complex insulation scenario, it’s a good idea to consult with a professional or hire a contractor to ensure the job is done correctly and safely.
Here are the top 10 most effective home insulation products, ordered by how effective they are at preventing heat loss, with explanations of why they work and links to buy them. These products help to reduce energy consumption and maintain comfortable indoor temperatures.
1. Kingspan Kooltherm K5 Insulation Board
Effectiveness:
Kingspan Kooltherm is one of the most efficient insulation boards available due to its high thermal resistance (low U-value), making it highly effective at preventing heat loss. It uses phenolic foam, which provides excellent insulation in a thinner profile compared to other materials.
How It Works:
The board traps air within its structure, preventing heat from passing through, and has a very low thermal conductivity.
Price: Approximately £30.00 per square meter
2. Celotex GA4000 Insulation Board
Effectiveness:
Celotex GA4000 is a PIR (polyisocyanurate) board that offers excellent thermal performance, making it highly effective for walls, roofs, and floors.
How It Works:
It uses rigid foam that slows heat transfer, reducing energy loss through walls and ceilings.
Price: Approximately £25.00 per square meter
3. SuperFOIL SF19+ Multi-Layer Insulation
Effectiveness:
SuperFOIL SF19+ is a multi-layer reflective insulation that reflects radiant heat back into the room, significantly reducing heat loss. It is highly effective when used in roofs and walls.
How It Works:
This insulation consists of layers of foil and foam that reflect heat, creating a barrier that reduces both heat loss and heat gain.
Price: £89.99 for a 7.5 m² roll
4. Rockwool Thermal Insulation Roll
Effectiveness:
Rockwool is an excellent insulator, especially for soundproofing and thermal insulation. It is highly effective in loft spaces and walls.
How It Works:
Made from stone wool, Rockwool traps air within its fibers, preventing heat transfer while being fire-resistant and sound-absorbing.
Price: £47.99 for a 5.76 m² roll
5. Earthwool Loft Roll Insulation
Effectiveness:
Earthwool Loft Roll is a highly efficient mineral wool insulation, designed to provide excellent thermal insulation for lofts and roofs.
How It Works:
Made from recycled glass and sand, the fibers trap air, providing effective thermal resistance.
Price: £24.95 for a 6.5 m² roll
6. ThermaWrap General Purpose Insulation
Effectiveness:
ThermaWrap is a versatile, reflective foil insulation that works well for walls, roofs, and floors, especially in combination with other insulation types.
How It Works:
It reflects radiant heat and creates a thermal barrier, reducing heat loss by reflecting heat back into the space.
Price: £22.49 for a 7.5 m² roll
7. Silverline Reflective Foil Insulation
Effectiveness:
Silverline Reflective Foil is highly effective in reducing heat loss through roofs, walls, and floors, especially when used as an additional layer of insulation.
How It Works:
This product reflects radiant heat, preventing heat from escaping through walls or roofs, which helps maintain a stable indoor temperature.
Price: £19.99 for 6 m²
8. YBS ThermaQuilt Multi-Layer Insulation
Effectiveness:
YBS ThermaQuilt is a highly effective, multi-layered reflective insulation designed to work in roofs, walls, and floors.
How It Works:
It combines several layers of aluminum foil, wadding, and reflective surfaces that trap air and reflect radiant heat, improving overall insulation efficiency.
