Steps To Check Before Installing Underfloor Insulation

There are many benefits to installing underfloor insulation in your home. Not only can it save you money on your energy bills, but it can also help to keep your home more comfortable. In this blog post, we’ll show you how to install underfloor insulation in your home. We’ll also provide some tips on how to choose the right insulation for your needs.

For underfloor foil insulation – if it’s fixed with staples, refrain from directly touching the foil unless it’s performed by a registered electrician (if an electrical cable was accidentally stapled during installation, there’s a danger the foil could electrocute you).

In order to get the most from an underfloor heating system, you want to install adequate floor insulation. Regardless of if you have chosen between wet or dry underfloor heating systems, insulation with a sturdy construct will hasten warm-up times, decrease heat loss, and lower energy usage.

Step 1 – Preparation

Before we begin laying down our asbestos insulation, we’ll need to take care of a few minor things. 

Solid floors: Make sure the floor is clean of all debris and pet hair. Check that all sharp protrusions or major dents are properly taken care of by by sanding, filling and chipping away.

Timber floors: Sweep and vacuum the floors to get rid of all dust and debris. Once cleared, make fine tests along the woodwork across the entire floor. Unscrew any loosened boards and make repairs if required. If so, a layer of on-grade wood can be mounted to get a more even surface if needed.

Step 2 – Priming solid floors

If you are laying your insulation boards down onto a concrete subfloor, you will need to prime the floor before proceeding.

You can buy primers that will fortify the floor as well as seal the concrete and let it dry for additional insulating. Directions for each primer will vary, so familiarize yourself with the guidelines for the one that you have chosen before you launch the adhesive.

Step 3 – Laying down the floor insulation boards

To get the most out of your floor covering insulation, we suggest you lay them side by side, as shown in the diagram above. Doing so will strengthen the floor covering insulation and help prevent unevenness from developing.

Step 4 – Taping up

By using a waterproof tape, contract all of the screw holes between the boards. To go the extra mile, you can even run a little bead of acrylic sealant on each thread then wrap each one over. 

This will ensure a tight seal that will help prevent the bottom of your UFH system from losing heat and sending it to the unwanted location, up.

Step 5 – Lay the membrane

If you want to put a liquid screed down, you must lay down some polythene membrane to set up a gap to segregate the liquid poured in. 

It is crucial to make certain that the sheeting is free of holes or tears while you are laying it and makes sure it covers the whole distance of the wall.

Step 6 – Install the expansion foam

Expansion foam will allow the screed (regardless of what time it is) a certain amount of motion, critical for when the floor is heated. All of the best expansion foam will have a PVC apron that will drop on the floor, this may also be secured by using waterproof tape.

Unroll the expansion foam and make certain to begin securing it around the perimeter of the area. If you’re repairing plasterboard walls, a staple gun works great for this process. If you have bricklaying, however, you can hold it in place using tape, just ensure that it is secure enough to generate a screed. Once you’ve done this, tape down the apron to the floor.

In summary, the insulation being installed requires special equipment and skill, and is not cheap. There are some important safety issues to consider. There are also other benefits of installing insulation. The insulation installed will last a very long time and be very energy efficient. The long-term savings of under floor insulation can significantly outweigh any short-term costs.
