Underfloor Insulation

What Is Underfloor Insulation?

Underfloor insulation is a simple and effective solution to generate thermal efficiency within homes; plus, there are various other benefits. In addition, floor Insulation can decrease moisture and dampness that is typically formed due to damp surfacing beneath the floor. 

But before laying down the insulation, one has to assess the type of flooring. For example, if the underfloor is half a meter off the ground, proceed with the insulation. Also, underfloor and ceiling insulation lead to insulated walls as well. 

Benefits of Underfloor Insulation

Thermal Efficiency 

Home and office spaces become more thermally efficient, courtesy of underfloor insulation. This means that temperatures are maintained organically throughout the year without added cooling and heating systems.

Reduction In Use of Artificial Air 

With maintained temperatures, home and office spaces are more self-sufficient, meaning that there is less reliance on heaters and coolers. Thanks to this, the following benefits can be reaped: 

1. Reduced Energy Bills 

Power bills are significantly reduced with less dependency on AC and heaters, leading to better savings and ROI from the underfloor insulation. 

2. Contribute to a Better Planet 

Due to less power usage – thanks to underfloor insulation – natural resources are conserved; in turn, more will be left behind for generations to follow.  

3. Preventing Cold Air From Entering Through The Floor

Cracks and holes allow air and heat to disperse via floorboard insulation. In turn, indoors get quite cold during winters. Essentially, a layer is created between external temperatures and floorings once underfloor insulation is installed. This layer restricts air from creeping out. 

Types Of Underfloor Insulation

Board Underfloor Insulation

Insulation floorboards are the most recognized choice for underfloor insulation because they are available for customizable rigid boards. In addition, insulation boards are a perfect combination to use with electric underfloor heating as they ward off the heat from the heating system flowing downwards to the subfloor. 

Polystyrene Floor Insulation

This is a cheap way of developing up floor levels while providing insulation. This form of insulation is not thermally efficient like roof and ceiling insulation; however, it does vary in densities. Using this method can be a cost-effective and unique way of insulating deep empty spaces. The most important thing it is biologically non-hazardous, and it is easy to handle due to its lightweight.  

Polyester Underfloor Insulation

This is the most long-lasting and safe technique for underfloor insulation available. A huge difference is made with added comfort, ensuring warmth in the winters and adequate temperatures during summers — properties similar to wall insulation. 

Polyester Rolls

This bulk insulation works by confining billions of minuscule air pockets in their formation, which divides the trail of heat and slackens it down. The effectiveness of bulk insulation decreases if the insulation is condensed.  Polyester rolls are composed of recycled plastic supplies and are cut before packing. They have no breathable fibres and are easy to handle. 

Underfloor Insulation Blanket

Underfloor insulation blankets reduce heat loss, improve energy efficiency and regulate temperature. They're made of fiberglass or other insulating materials, come in various sizes and thicknesses, and are easy to install. R-value and fire safety regulations should be considered when choosing the right insulation blanket.

Underfloor Foil Insulation

Underfloor foil insulation is a type of insulation that consists of a thin layer of reflective material, such as aluminum foil, that is installed beneath the floorboards. It works by reflecting radiant heat back into the room, and can be a cost-effective way to improve energy efficiency and reduce heat loss.

Installation And Care For Underfloor Insulation 

1. One must wear a dust mask and a pair of precautionary glasses
2. Then enter the area under the floor, either through the basement or the crawl space
3. Examine the site for any openings where electrical wires pass through the wall and the floor joists
4. Use a caulk gun and attach a tube of exterior silicone caulk and chop off the nozzle head with a knife. Press the caulk gun trigger and seal any voids or gaps
5. With a connected vapour barrier, unfold a roll of kraft-faced insulation. And tuck the first batt of the registration into the space linking two-floor joists with the vapour barrier in an upward direction against the subfloor loosely and with the paper-faced side faced downhill. Commence at one edge of the joists and strive towards the centre. 
6. Fold the insulation between any electrical wires, ductwork, or plumbing associated with the floor joists
7. Unwrap the flaps of paper on the side of the batts and the lower inside faces of the floor joists.  Remember to staple using the construction stapler at a distance of 6 inches. 
8. Use a utility knife and cut the insulation and kraft paper cleanly where the insulation meets the wall. Carry on insulating between the joists until the complete floor is protected. 

Maintenance Of Floor Insulation

Once installed, underfloor insulation is maintenance-free. With little to no upkeep, the insulation will last for a very long time.
