Under House Insulation: The Complete Guide

under house insulation

Insulating under a raised house poses a unique situation. Houses built on crawlspaces, pads, or basements have built-in barriers to the outside.

However, a raised house doesn’t have that barrier.

This means the floor functions much like an exterior wall, as it is directly exposed to the outside. In other words, it is directly exposed to wind, cold and moisture.

Choosing the right insulation is crucial to keeping your house comfortable, and protecting your flooring from moisture, animals, and insects.

It can also save you money, and who doesn’t want to save money?

With that in mind, we’ve compiled the complete guide to insulating your floors with spray foam, including how to do it, why it works, and what it can save you over time…

The ideal insulation for your raised house will deliver on all three fronts, ensuring a healthier, home environment and an immeasurable improvement in comfort

Underfloor Insulation: Key Points

There are three main goals for underfloor insulation. These are:

-To provide the appropriate R-value: R-value measures the ability of insulation to resist heat transfer. A higher R-value means more insulation and less heat transfer. In the summer the heat stays outside, and in the winter, the heat stays inside.

-Eliminate airflow: This prevents drafts,and helps keep your home at a constant temperature.

-Resist and impede moisture flow: This is especially important for homes located in humid and damp areas, and during periods of rain.

The ideal insulation for your raised house will deliver on all three fronts, ensuring a healthier, home environment and an immeasurable improvement in comfort.

Spray Foam: What Does It Offer?

Spray foam is the premium product of choice for insulating under the floorboards. It provides thorough coverage of the space, and forms a better seal against any air infiltration. These qualities make it the most airtight option on offer.

Most spray foam consists of two different liquid ingredients that are kept in separate containers. At the installation site, the insulation professional uses hoses that are connected to both containers.

The ingredients flow through these separate hoses to a mixing gun. When the ingredients reach the mixing gun, they instantly react to become foam.

The foam is water-blown, and expands to 100 times its initial size. It completely fills and seals the area to which it is applied. There are no gaps or spaces left between the insulation and the bottom of your house.

The most impressive benefit of open cell spray foam is the superior energy efficiency it provides. This translates into more significant savings on your energy bills

Benefits of Installing Spray Foam Under the Floorboards

In the UK, energy bills have doubled since 2004 and you can offset some of that increase by making your home more energy efficient. It is estimated that up to 56% of a home’s energy goes toward heating and cooling.

In addition to this, up to 40% of a building’s energy is lost through air infiltration. Take a look at just some of the benefits of this type of insulation:

  • Resistant to water
  • Increases structural strength
  • Mould resistant
  • Someone else does the work and installation, you can sit back and relax
  • Work is completed in only a few hours
  • Seals the space under your home
  • Fills in any gaps
  • Acts as a pest deterrent
  • Reduces infiltration of air pollutants
  • Creates a consistent, comfortable temperature in your home

But the most impressive benefit of open cell spray foam is the superior energy efficiency it provides. This translates into more significant savings on your energy bills.

Sit back, relax, and let the professionals do all the hard work on your behalf. No mess, no fuss, no frustration-just years of ongoing benefits for your building. At the end of the day, you’ll have an expertly insulated home, and the energy saving advantages that come with it

Can I Just D.I.Y My Spray Foam Project?

The short answer is no. Spray foam installation requires a higher level of expertise in comparison to other forms of insulation, that can be carried out by the average homeowner.

First, spray foam installation is messy. It gets on hair, skin, clothes, and any nearby surfaces it comes into contact with. It is imperative that surfaces be covered, and that appropriate clothing is worn.

Assistants need to be close at hand to monitor progress, and quickly cover things, if needed. Insulation specialists know how to handle all of these issues, and work effectively at insulating your home.

It is also important to work deliberately, and with meticulous attention to detail. If foam is applied at the wrong temperature, or mixed in the wrong ratios, it will not be nearly as effective.

For all these reasons, DIY spray foaming is not recommended. Hiring a professional ensures correct mixture and installation of spray foam, to the highest standard you deserve.

So sit back, relax, and let the professionals do all the hard work on your behalf. No mess, no fuss, no frustration-just years of ongoing benefits for your building. At the end of the day, you’ll have an expertly insulated home, and the energy saving advantages that come with it.
