Likely improperly insulated or not insulated at all. Measure the floor temperature as well as the air temperature. Also sounds like your heating system should be balanced better (it should somewhat actively mix the air, rather than just letting the heat flow upstairs.)
Never place insulation close to water heaters, oil burners or anything hot. The backing is especially flammable and will be a major fire hazard for your home.
Insulation is a material that is used to slow the transfer of heat between the inside and outside of your house. It acts as a barrier, keeping the heat out during the summer and retaining warmth during the winter. There are a variety of different types of insulation and many different areas it can be installed.
Insulation keeps your house cooler in the summer by blocking heat, keeping indoor temperatures stable, reducing heat entry, saving energy, and reflecting heat. This makes your home more comfortable and energy-efficient. Here's how it works: Stops ...
The short answer is yes. Effective insulation can help keep cool, air-conditioned air inside and keep the heat out for a more comfortable summer at home.
How many degrees of difference insulation makes on its own depends on the type of home you have, what the weather is like and what kind of insulation you have. Depending on what you choose, you could see a five- to 20-degree temperature difference just based on the insulation alone.
In the winter, this means trapping and absorbing the heat from the home's heating system and keeping the warmth from escaping out into the chilly outdoors. In summer, however, insulation functions to keep the cold air in, and the hot air contained to the attic, where it rises naturally due to “The Stack Effect”.
It is possible to over-insulate your house so much that it can't breathe. The whole point of home insulation is to tightly seal your home's interior. But if it becomes too tightly sealed with too many layers of insulation, moisture can get trapped inside those layers.
“Pipes can expand in high temperatures, leading to leaks or even bursts, especially in older systems. And when it comes to electricity, the increased power consumption during hot spells can overload your system, potentially causing circuit issues or, in worst-case scenarios, electrical fires.”
Irritation to skin and respiratory system
Wall insulation solutions like Rockwool are made of ultra-fine fibres. While thermally efficient, they can cause skin and respiratory irritation.
Moisture damage
This can occur due to leaks in the roof or foundation, inadequate ventilation, or high humidity levels inside a building. Moisture can cause the insulation material to become compressed and lose its effectiveness, leading to increased energy consumption and potential mold growth.
If you're cold even though your thermostat indicates you shouldn't be, your furnace likely isn't the problem. In most cases, it's working just fine. It's your home that needs attention. Lack of insulation, severe air leakage, and/or unbalanced ductwork are frequently to blame.
What causes cold walls? Poor insulation is the main reason why walls feel cold, especially in older properties with solid walls. Roughly 35% of heat loss is through walls and gaps, in and around windows and doors. Walls transfer heat and the warmth from your home will escape outside if your walls are poorly insulated.
Most forms of insulation can last for decades under ideal conditions. However, various issues inside your home can make retrofitting or replacement necessary much sooner. Some homes have the original insulation for upwards of a century, while others may require upgraded insulation in as little as 15 years.
Leaving Too Many Gaps
One of the biggest problems DIY homeowners face is leaving too many gaps in their insulation. Gaps or insulation that isn't secured correctly can leave the building structure open to air and moisture leaks. Spray foam insulation is best for reaching into small cracks and any areas left open.
The optimal R-value for most homes is 30, but you can go as high as 38 if you live in a tropical climate. Anything higher than 38 indicates an over-insulated space. While you might think that too much insulation can't be bad, there are some significant consequences to consider.
Lifespan of cavity wall insulation materials
Polystyrene beads can last up to 100 years due to their resistance to moisture and decay. Polyurethane foam and mineral wool are durable, typically lasting over 50 years. Extruded polystyrene (XPS) has a 20—to 30-year lifespan, and fibreglass can last 80—to 100 years.
Even with new insulation, your home might feel cold due to air leaks and drafts around windows, doors, and vents. A reason can be gaps or compression in insulation can limit its effectiveness, diminishing thermal resistance.
In reality, insulation does next to nothing to stop unwanted airflow. It's not just a matter of choosing an insulation that blocks more airflow than most. Insulation is designed to slow heat transfer, not to block air. It helps your home act like a Thermos, keeping hot things hot and cool things cool.
Based on new research, the North American Insulation Manufacturers Association (NAIMA) estimates that roughly 90% of existing U.S. homes are under-insulated. That means that the occupants are less comfortable, and both energy and money are being wasted.
Most people assume that insulation is something that keeps their home warmer in colder weather. While that is true, the actual impact of insulation is to slow the movement of heat between two spaces. What this means is that during the summer months the insulation will also prevent your home from overheating.
