Attic bedrooms? A cozy retreat, even when you want something as simple as a change of view within your home. With that said, choosing the right attic bedroom window is more than just “aesthetics”. Why do we say that?

Living in Canada, you already know how tormenting and chilly the winters can get. So, when you’re up in the attic, enjoying your cozy retreat can become a huge challenge if you’re dealing with poor ventilation and more importantly, poorly insulated windows.

Now, that can lead to two of the most distressing issues. First, your own home can go from being a place of comfort to one of inconvenience (due to inconsistent temperature). And second, high energy bills! So, what’s the solution?

At Canadian Choice, we think that your windows need energy-efficient glass panels – and a few other useful features. In this short and helpful guide, we’ll explore a few good window options for optimal ventilation and insulation in your home.

Key Takeaways :

  • Attic bedrooms face both temperature extremes and limited ventilation among other issues (like moisture buildup)
  • Choosing the right windows means looking at aspects like double-hung sashes, awning, and casement
  • Your choice of windows should lead to optimal airflow, insulation, and overall comfort
  • The best energy-efficient glass options have a “Low-E” coating and double or even triple glazing to reduce heat transfer
  • You should go for strategic window placement to significantly enhance cross-ventilation and natural light pathways

Common Issues in Attic Bedrooms

A quick overview of the most common issues in attic bedrooms will help you make an even more informed decision. For instance, attics face issues like poor air circulation but at the same time, they are also more vulnerable to moisture infiltration. Take a look around your attic and if you notice any of the following issues, you’ll need a comprehensive solution to tackle – and prevent – them all.

Heat and Cold Transfer

You may already know this but attic bedrooms are notorious for temperature extremes. During summer, you will find them extremely unbearable with the roof as hot as the griddle at an iHop during Sunday brunch hours – it absorbs and traps heat. But in winter, the lack of insulation makes cold air seep in easily.

That makes it a nightmare for attic dwellers and spikes the energy bills at the same time. If your attic has poorly insulated windows – for instance, due to single-pane windows, which are a common culprit for this issue – then you have uncontrolled heat transfer to deal with.

In simple words, single-pane windows let warm air out and cold air in, very easily.

Attic Bedrooms

Limited Airflow

The next common issue with attic bedrooms is the structural design. The structure will affect the natural airflow which will determine the level of ventilation in the space. If you have sloped ceilings and small spaces with restricted openers, you will be dealing with stagnant air on a daily.

Similarly, poor ventilation will also create a “stuffy” feel and make it unenjoyable to sleep or relax in the attic. Since windows play a crucial role here, you have to design and strategically place them around the attic for maximum benefits. Your goal should be to bring fresh air in easily and let stale air out.

Moisture Build-Up

And finally, we have moisture build-up as the most common nuisance in attics. They not only create an uncomfortable and soggy atmosphere but also increase the risk of mould growth. In the long run, moisture-holding attics are a health hazard for the entire home. Why? Because moisture build-up can lead to:

  • Mold and mildew growth
  • Poor indoor air quality
  • Structure damage (to walls and ceilings)

Best Window Types for Attic Bedrooms

When talking about attic conversion windows, it depends on your functional and aesthetic needs. In fact, you can get both with a custom-made attic window. Here aer some of the most popular attic window types.

Casement Windows for Maximum Ventilation

Many homeowners often go for casement windows for attic rooms because they open outward and use the simple “crank” mechanism. That way, you can catch breezes and direct fresh air into the room without complicating your stay in the attic.

It is particularly effective if you have limited attic space but require improved airflow. Plus, they come with tight seals which make them an ideal choice to prevent air leaks. With airtight seals around the edges, casement windows can improve overall energy efficiency.

Casement Windows for Maximum Ventilation

Awning Windows for Tight Spaces

Have a smaller attic space or perhaps, high walls in your attic? You can go for awning windows that open outward from the bottom and create a small “awning-like” effect. As a result, it allows ventilation even during light rain thanks to the opening mechanisms.

They are well-suited for your attic bedroom if you have or plan to go for an unconventional layout. You can easily install awning windows in tight spaces without compromising functionality. On the other hand, most of these types come with a weather-resistant design to add more durability.

Awning Windows

Double-Hung Windows for Versatility

For homeowners who value versatility, we have double-hung windows as a top choice among locals. While they’re not so common, they are an excellent choice for attic bedrooms. With double-hung windows, you can open the two-operable sashes from the bottom, the top, or both.

The design is extremely effective for ventilation, simply due to the sheer size and opening versatility of their design. Furthermore, these windows are easy to clean and maintain which is an added benefit for homeowners.

Fixed or Picture Windows for Insulation

If ventilation has taken a backseat in your attic, thanks to insulation and natural light, you can go for the aesthetic option. While fixed or picture windows are non-operable, they do offer thermal performance because they completely eliminate air leaks and drafts.

Do you live in a region with the harshest and longest winters? You can pair fixed windows with sturdy glass panels with Low-E coatings. Some homeowners prefer triple glazing to ensure heat retention while making it an aesthetic addition to attic bedrooms.

Picture Windows

Helen Sin, Consumer Success Manager , says, “ Attic bedrooms are best suited for casement or tilt and turn windows, as their egress capabilities ensure safety while providing excellent ventilation. For uniquely shaped openings, architectural windows can be tailored to fit perfectly, adding character and style. Pairing these with advanced glass configurations, such as low-E coatings or triple glazing, ensures optimal comfort by managing temperature and light. Together, these solutions create a safe, stylish, and comfortable space.

Features to Prioritize for Ventilation and Insulation

To stay cozy and comfortable, you need an attic that lets you breathe fresh and maintains the warmth. So, don’t forget a few essential features to make sure your the window in the attic creates a comfortable, energy-efficient space.

Energy-Efficient Glass

You can introduce energy-efficient glass into your attic windows to battle the temperature extremes. We recommend going for Low-E coatings that will reflect heat back into the room and improve heat retention during winter. Conversely, they will block solar heat during summer and improve overall insulation.

You can again consider triple-glazing for your window glass to increase energy efficiency. The more panes there are, the more air and gases are trapped in windows to reduce heat transfer. Although they sound simple, they can lead to noticeable savings on your energy bills.

Proper Window Frames

The type of window frame material you go for will directly affect the insulation in your attic. In addition, it will also affect the durability of your window. For starters, you can go for vinyl frames which are great for insulation efficiency while being an affordable, low-maintenance option.

On the other hand, fibreglass frames may have better thermal performance and are most definitely higher durability. However, that comes with a slightly higher price tag. So, if you want natural insulation with classic aesthetics that requires regular maintenance, you should go for wooden frames.

Operable vs. Fixed Windows

One way to increase insulation is to go for fixed windows . Similarly, one way to go for better ventilation is to opt for operable windows, like the awning and casement windows. With moving windows, you have more control to adjust the airflow inside the attic.

That will help you reduce the stuffiness and create a more spacious and roomy environment in the attic. This is particularly helpful if you’re dealing with limited attic space. But if you’ve got ample space and the regional climate makes it an option, you should go for fixed windows with good Low-E coatings (i.e., where ventilation is not the top priority).

Window Placement

Last but not least, we have window placement to determine the level of ventilation and airflow you enjoy in your attic bedroom. For example, you will enjoy natural light if it’s a south-facing window. That way, you will be saving on artificial lighting as well.

On the flip side, if you go for opposite-wall window placement, you can enjoy cross-ventilation for a fresher and more comfortable environment.

The Role of Professional Installation

How can a professional team of window experts help? There are a few good reasons, especially with Canadian Choice by your side. We say that because even the best attic roof windows can underperform if you install them incorrectly.

They will lead to more cold air seeping in, and more warm air leaking out. With professional installation , you can take care of those functionality issues and the aesthetic standards at the same time. Take a look at the most valuable benefits of professional attic window installation.

Airtight Seals and Proper Fit

For instance, a professional from our team will make sure that every window installation takes place with the help of precise measurement and fitting. This will prevent air leaks and also help you control moisture intrusion inside the house. For attic spaces, this can also mean a significant reduction in the risk of structural irregularities.

Custom Solutions for Attic Spaces

With experienced professionals by your side, you can take functionality and aesthetics together. You can go for highly optimal and efficient windows while making sure they suit the overall interior (and exterior) of your attic. For example, with our company, you can get bespoke window shapes, optimized placements, and more.

Long-Term Benefits of Expert Work

There are long-term returns on professional installation, like a reduced likelihood of drafts and condensation. Both of those are major issues behind unexpected energy bill hikes during the chilly winters of Canada. Plus, don’t forget, that professionals offer warranties for smoother repairs and replacements.
