Can You Over Insulate A House?By admin
Thursday, 15 November 2018
Insulation is a huge topic in home renovation. It’s no secret that efficient insulation can save you money on your bills, but the amount can be truly staggering.
Yes, being green and thinking about the environment is great, but in the end, it all comes down to whether you can save substantial money or not. In that spirit, many homeowners try to add more and more insulation.
But can you take your insulation efforts too far, and over insulate a house? To answer this question, we’ll start by exploring the ‘over insulation myth’…
What is the ‘Over Insulation Myth?’
The ‘Over Insulation Myth’ suggests that people should not seal up their house too tightly because a building needs to breathe.
Needless to say, it really is just a common myth-and one which we’re pleased to dispel.
The root of the myth dates back to the houses of the 1970s. Back then, homeowners had not figured out that houses comprise of several main systems.
They just sealed up the houses, trying to eliminate the energy wasted on infiltration. What happened is that they forgot that houses need mechanical ventilation.
Mechanical ventilation is the solution to many of the problems that occur in “too tight” houses. Some of the problems that happen when you “over insulate” a house include: poor indoor air quality, high humidity, and, in some cases, an increase in mould growth and hazardous spores.
Generally speaking, we notice random leaks, and we seal them up. But it is important to understand that random leaks do not bring in fresh air. One way to bring fresh air is by mechanical ventilation
Green Homes are Insulated Well
The fact of the matter is that green homes are insulated well, and possess adequate ventilation.
The reality is that air leaks mean you’ve lost control of air movement. Effective air and moisture barriers, something you create with proper insulation reduce problems like uncontrolled air movement, energy waste, and increased risk of damage to building components.
At the very least, insulation should meet the recommendations by the Department of Energy. The question is not whether can you over insulate a house. The more important question is where you place insulation, and what type of insulation you use.
Not all insulation types are same, and not all of them carry the same R-value.
For example, you can add an extra layer of rigid insulation outside the framing, to help walls and roofs keep energy inside.
As a powerful insulator, spray foam offers incredible energy savings. When you insulate your house with spray foam, you can expect energy savings of up to 50%!
Spray Foam Insulation Benefits
That being said, we firmly believe that spray foam insulation is one of the best types of insulation available. Spray foam insulation is perfect for closing holes and cavities, and much more. Here are some of the main benefits of installing spray foam in your home:
- Spray foam works better than other types of insulation, due to its expansive nature. Using spray foam can help you seal all nooks, crannies, and other problems that would have otherwise been left exposed. Closed-cell spray foam insulation has an R-value of 6, which is the highest rank on the market
- As a powerful insulator, spray foam offers incredible energy savings. When you insulate your house with spray foam, you can expect energy savings of up to 50%
- The unique ability of spray foam insulation is to provide air-tight seal. None other insulation type can provide the same seal. The preferred space for using spray foam insulation is sealing holes and cracks in the attic or crawl space. And if you didn’t know, air leaks are the biggest reason for high energy bills
- Most importantly, cracks and holes encourage more than cold currents inside. They also allow moisture to gain access to internal areas. Spray foam prevents that, since it is impermeable to water.
- Last, but not least, spray foam deters mould. Since it is composed of inert polymer, spray foam is not a breeding ground for mould or bacteria
- Most importantly, spray foam insulation has a long life-span of 20 years and more, and is incredibly eco-friendly

Avoid D.I.Y Spray Foam Insulation Projects
While you cannot over insulate a house, you can install improper insulation. Knowledge, experience, and professionalism matters in this business. Insulation generally requires a professional installer, and if you wish to opt for spray foam, than enlisting the experts is paramount.
An experienced contractor will be able to answer all of your questions about the project, and the products they will use in practice. The contractor will also give you tips and tricks how to maximise savings on utilities during Winter and Summer, as they know their way around the house.
An experienced contractor will also make sure you receive your desired results. Look for specialists that are certified for their work.
But most importantly, licensed contractors will make sure that safety is top priority. They will safely remove any old insulation that you might have. Old insulation might contain asbestos or mold, and it is imperative that a qualified professional removes it.
By opting for a certified installer, you can rest safe in the knowledge that you will get an adequately insulated home, and one that will bring you energy saving benefits for years to come! Simply call 0800 1700 636, or click the button below to enlist the help of the experts today!
