Can You Add Insulation to Existing Walls?

Having a fully insulated home with the right materials is like wrapping yourself in a cozy, protective blanket that shields you from the harsh elements, ensuring year-round comfort and efficiency.

Whether you aim to improve your home’s energy efficiency or just want to ensure your home stays comfortable year-round, adding new insulation over existing insulation can be a strategic and effective solution.

However, there are several factors to consider before taking the plunge.

Understanding Existing Insulation

A solid understanding of your existing insulation is an important first step in adding new insulation. Some common types of insulation are:

  • Fiberglass batts: These are pre-cut panels made of fine glass fibers and are easy to install but can lose effectiveness if they become compressed or wet.
  • Cellulose: Made from recycled paper products treated with fire retardants, cellulose insulation is commonly blown into wall cavities. It settles over time, which can reduce its insulating properties.
  • Spray foam: This type of insulation is applied as a liquid and expands to fill spaces. It provides higher-quality air sealing and insulation but can be expensive and challenging to remove.

Considerations Before Adding New Insulation

  • Inspection and assessment: A thorough inspection will identify areas where the insulation is damaged, compressed or settled. This assessment will help you determine whether adding new insulation is viable or if the old insulation needs to be removed.
  • Compatibility: Not all insulation materials work well together. For instance, adding fiberglass batts over existing spray foam might not be ideal. Ensure the new insulation is compatible with the old to avoid uneven insulation or potential chemical reactions.
  • Moisture and mold concerns: Adding insulation over damp materials can exacerbate mold problems and reduce the insulation’s effectiveness.
  • Insulation thickness: Over-insulating can cause diminishing returns and may lead to structural issues. Consider the recommended R-value (a measure of thermal resistance) for your climate, home layout, and specific needs.

Benefits of Adding New Insulation Over Old Insulation

  • Enhanced energy efficiency: Adding new insulation over old can significantly boost your home’s energy efficiency. This additional layer means your home’s heating and cooling system doesn’t have to work as hard to keep your home comfortable.
  • Improved comfort: Increased insulation levels lead to more consistent indoor temperatures. They reduce heat transfer and the opportunity for drafts, meaning more stable temperatures consistently and an overall improved comfort level in your home.
  • Cost savings: When your heating and cooling system isn’t working as hard, you’ll notice substantial savings on your energy costs and monthly utility bills.

How to Add New Insulation Over Old Insulation

  • Preparation steps: Start by preparing the existing insulation and space. This involves removing damaged or wet insulation, sealing air leaks, and ensuring the area is clean and dry.
  • Installation techniques: You can leverage new insulation techniques like blowing, which is ideal for filling gaps, or adding batts over existing batts.
  • Professional vs. DIY: While DIY installation can be cost-effective, hiring professionals ensures the job is done correctly. Professionals have the expertise to handle complex insulation projects and can ensure a seamless installation process, providing peace of mind and less stress.

When Should You Remove Old Insulation?

In some situations, completely removing old insulation is a better course of action. If you notice severe damage, contamination, pest infestations, or mold, your existing insulation should be removed.

Additionally, if you’re hoping to upgrade to higher-efficiency insulation, it may not be compatible or possible to blend with existing insulation. This will be key when weighing the benefits of the new insulation vs. a different type.

Why You Should Consult Professionals

Adding new insulation over existing insulation can be a highly effective way to enhance your home’s energy efficiency and comfort. However, it’s crucial to evaluate the current state of your insulation, ensure compatibility, and address any moisture issues before proceeding.

Consulting with insulation experts like our team of highly trained professionals at Therm-Con is the best first step. We can provide personalized advice and ensure the job is right, leading to a more comfortable and energy-efficient home.

Gas vs. Wood-Burning Fireplace: What Fireplace Should You Choose?

Fireplaces and You

It’s a cozy winter night, so you make a mug of hot cocoa and curl up on the sofa. What completes this picture? The warm glow of a softly burning fire in your home fireplace. Adding a new fireplace to your house or modifying an existing one is a wonderful home project with many important decisions to make along the way.

One key factor in selecting the right fireplace for your home is what fuel source your fireplace should use. Gas and wood-burning fireplaces are increasingly popular options, but which is the best fit for you?

To make this choice, let’s review the role a fireplace will play in your home, the benefits of gas and wood-burning models and the impact of lifestyle, efficiency and personal preferences on your perfect fireplace selection.

Does Your Home Need a Fireplace?

The two main reasons people want a fireplace in their home are functionality and ambiance. A fireplace’s function is simple: It produces heat. It supplements the broader heating system you already have installed in your home. Getting one comes with a set of practical considerations like safety, convenience, installation, maintenance and the project’s overall cost.

Ambiance, while harder to define, is often no less important. What kind of feeling do you want the fireplace to contribute to your home, and how will the customization options, cleaning routine and sensory experience of any given fireplace meet those wants and needs?

Also worth considering is your unit’s environmental impact and how the installation of a fireplace will impact your home’s resale value.

Benefits of a Gas-Burning Fireplace

A gas-burning fireplace’s greatest strength is its convenience, from maintenance to cleaning. Here’s a fuller breakdown of considerations:

  • Convenience: These fireplaces don’t require complex prep time to use and are often operable via remote control.
  • Customization: While there are plenty of flexible options for both gas and wood-burning fireplaces, gas offers a slightly wider array.
  • Environmental impact: These units release fewer pollutants. However, unlike wood, gas is not a renewable resource.
  • Cost: This can vary depending on where you live. While these units are more costly in some respects, they may balance out if you live in an area without ready access to firewood.
  • Safety: Both units have important safety considerations. Potential problems that could arise from a gas-burning fireplace, like carbon monoxide or a gas leak, are rare and simple to prevent through regular annual inspections.

Benefits of a Wood-Burning Fireplace

There is no match for the charm of crackling firewood in a well-tended hearth. While this might make wood fireplaces a clear winner for those seeking ambiance, there are plenty of other benefits to this classic:

  • Cost: If you have ready access to firewood, a wood-burning fireplace may be a more affordable option.
  • Convenience: These involve more setup as you prepare your fire. However, for many people, the effort of building and tending to a fire is part of the rich experience they want in a home fireplace.
  • Safety: There is a different level of active participation from the user, but a wood fire is perfectly safe with proper supervision.
  • Maintenance: Ash removal and annual inspections are the main maintenance considerations for these units.
  • Environmental impact: Wood is renewable, though burning it releases more CO2.

Finding the Right Fireplace for Your Home

Whether you’re better served by a clean, convenient gas fireplace or the earthy beauty of an affordable wood-burning one, there are plenty of options available to suit the needs of your personality, home and budget.

Rather than accepting a one-size solution that might not fit your needs, we recommend some research and even soul-searching as you decide how you want your winters to look and feel.

Choosing the Right Fireplace Style

Along with the fuel source, you’ll also need to consider the style of your fireplace. There are many different style choices available, each of which adds something unique to your space:

Contemporary Fireplaces

These feature clean lines, minimalistic designs and sleek materials such as glass or metal. They offer a modern, streamlined aesthetic best suited for contemporary or minimalist interiors, such as urban lofts or modern homes.

Traditional Fireplaces

Traditional fireplaces are characterized by classic designs, ornate mantels and wood or stone materials, which evoke a sense of timeless elegance and cozy ambiance. They’re best suited for rustic home interiors, creating a warm, inviting atmosphere.

Multi-View Fireplaces

A multi-view fireplace features an opening on two or more sides, allowing you to view flames from different angles. They act as a great focal point in your room and are ideal in larger living areas with multiple seating arrangements.

Open-Hearth Fireplaces

Open-hearth fireplaces feature wide, open fireboxes with exposed flames that offer an unobstructed view of the fire. Homes with spacious living areas will find an open-hearth fireplace ideal as the room’s centerpiece.

Firebox Fireplaces

A firebox fireplace is compact and prioritizes containing the fire, offering a minimalist, efficient design ideal for smaller spaces or modern interiors that focus on simplicity and functionality above all else.

Best Rooms for Fireplaces

The next thing you’ll need to consider when adding a fireplace to your home is where to put it. There are several areas in the home where a fireplace works best, including:

  • Living rooms: A classic choice for a fireplace installation, adding a fireplace to your living room can make it cozy and inviting.
  • Home study:Ā Adding a fireplace to your home office can create a warm, productive atmosphere — especially during cold winters.
  • Bedrooms:Ā A bedroom fireplace adds a touch of luxury and romance to your space, offering a cozy retreat that keeps you warm on cold winter nights.
  • Guest suites:Ā Provide a welcoming feature for your house guests by adding a fireplace to your guest suite area.

Budgeting for a New Fireplace

Finally, it’s time to set a budget for your fireplace installation. The cost of your fireplace will depend on several factors, including the type of fireplace you choose, the size and complexity of its design, installation fees, venting considerations and mantel materials.

Determine your budget range before shopping for a fireplace, taking into careful consideration both the cost of the product and the installation costs.

It’s important to keep in mind what the ongoing operational costs will be for your new fireplace as well. Look into your area’s wood, gas and electricity costs to select the most cost-efficient option for your location.

Also consider how maintenance and repair needs will factor into the total cost of your installation.

Benefits of Converting to a Gas Fireplace

Many homeowners don’t realize that converting their fireplace is an option because they misunderstand the benefits or overestimate the cost and difficulty of converting.

Some of the advantages of converting to gas include:

  • They’re more convenient and efficient than wood fireplaces.
  • There’s no need to chop or store wood.
  • There’s no need to clean up ash.
  • There’s no need for matches, lighters, starters or kindling.
  • They provide a cleaner aesthetic.
  • The fire can be put out immediately.
  • Remote or voice activation, deactivation and control are possible.
  • They use cleaner-burning fuel.
  • They’re easy to use.

What Are Your Gas Fireplace Options?

When converting to a gas fireplace, you have several options to choose from. No matter what, you’ll need to have a natural gas line installed. Considering the complexities and potential risks associated with natural gas, make sure the gas line is installed by a qualified, licensed professional.

Each type of gas fireplace has advantages when compared to the others. From chimney requirements to cost, they all have their unique benefits and should be considered against your budget, home specifications and comfort requirements.

Once you’ve determined which type is best for you, there are many styles, finishes, controls and other factors to consider.

Primary gas fireplace types to consider include:

  • Direct-vent gas inserts: These require a chimney or vent. Pollutants get vented out of your living area, but so does some heat. Vented models take longer to install. The results are a more traditional look and feel. They’re more compliant with building codes, but they’re also the most expensive gas fireplace option.
  • Ventless gas inserts: These don’t require vents due to more efficient burning. Minimal pollutants get released into your living area, but indoor air quality is affected as a result. More of the heat produced stays in the living space. They also tend to be less expensive than vented options.
  • Gas log inserts: These can be either vented or ventless. They’re designed to look just like actual wooden logs and enhance the visual aesthetic of the fireplace. Styles are available to mimic specific types of wood, charring and even stacking.
