What Are PRISM Windows?

The PRISM window line by Ostaco is at the leading edge of window technology and design. In this blog, we are going to go over the benefits of PRISM windows and why you’ll want to consider using them for your next project.


Our engineering team had one objective — less frame and more glass than any other vinyl window.  PRISM is progress.  Some of the structural upgrades to the PRISM window include:

  1. Fusion-welded vinyl chambers.
  2. Internal steel reinforcement channel.
  3. Mullion pocket to facilitate structural reinforcements when combining large units.
  4. Santoprene bulb seals improve the sash/bulb contact area for a consistent season and improved performance.
  5. Commercially rated structural performance designation (Results available upon request).

Energy efficiency

PRISM windows are rated most efficient by ENERGY STAR®.

Available in either ⅞” dual-glazed or 1-⅜” true triple-pane glazed. Our customers get industry-leading energy performance and sound reduction, especially with true triple-glazed.

The PRISM window also has self-adjusting weatherstripping that provides the highest possible resistance to air and water infiltration (Results available upon request).

Finishing touches

All PRISM hardware is supplied by the industry-leading manufacturer, TRUTH HARDWARE. With the new TRUTH Contemporary Handle and Lock, you can choose from white, black, and satin nickel — it is the ideal option to complement the low-profile window design. PRISM windows also come with a heavy-duty, multi-point locking system that will provide your home with the safety and security that you want.

And lastly, colour options. You will be able to choose from Ostaco’s standard colours or you can supply a colour swatch for matching. Whatever theme or character you want your home to have, colour makes all the difference.

Spring is the perfect time to replace windows from Ostaco

Why Spring Is The Perfect Time To Replace Your Windows

When it comes to replacing your windows, it can really be done at any time of year. It’s important to replace your windows as soon as they begin to break down, so you can keep your home safe and comfortable.

However, if you’re more flexible and replacing your windows is not an emergency, spring is the perfect time of year to replace your windows:

1. The weather is mild

One of the main reasons that makes spring the perfect time to install new windows is that the weather is mild, and tends to be predictable. The chance of snow has likely passed, and your home won’t be exposed to extreme cold or heat while the installation takes place.

2. The days are longer

During the spring and early summer, we get longer days, with more hours of sunlight than in the fall and winter. While that doesn’t mean you can’t install windows during the rest of the year, spring days give your installers more daylight hours to work and, as a result, the installation may take fewer days to complete.

3. Ideal for caulking

Installing new windows involves caulking, and caulk can be susceptible to extreme weather. Spring temperatures are mild and are not typically extremely hot or extremely cold, which allows the caulking to easily adhere to the windows and your home.

4. Longevity

Weather can also impact the window material itself. Most new windows are made of aluminum and vinyl, which expand in warm weather and contract in cold temperatures. This can cause movement of the substrate, which can weaken the integrity of your windows. Installing windows in the spring can avoid this issue.

Hiring a reputable and experienced window installation company means that you can have windows installed at any time of year. Find an Ostaco Windows & Doors dealer near you.

Top Benefits of Investing In New Windows & Doors

If you’re a homeowner, investing in new windows and doors is one of the best things you can do for your home. From increasing your curb appeal to improving your energy efficiency, here are the top benefits of installing new windows and doors:

1. Safety and security

If your home’s windows and doors are old and beginning to show signs of wear, they could be making your home more susceptible to break-ins. Replacing damaged windows will help provide you with more security. Modern windows and doors also come with more security features, like multiple locking systems, which can make your home even safer.

2. Curb appeal and resale value

Damaged and old windows and doors can look unsightly, detracting from your home’s overall appearance and curb appeal. New windows and doors will help to give your home a refresh and can increase your home’s resale value. In fact, investing in new windows can result in 84% of a return on your investment if you decide to sell your home.

3. Improved energy efficiency

Old windows and doors are not as energy efficient as newer models. New windows are typically made of multiple panes of glass and special glazing to prevent heat loss, and energy-efficient materials like vinyl. Old windows and doors may also be beginning to break down and letting air out through cracks and broken seals. Upgrading your windows and doors can help you save money on your utility bills.

4. Fewer repairs

As your windows and doors age, they will typically require more maintenance and regular repairs to keep them in good shape. With advancements in technology, newer windows and doors require less maintenance, so installing new windows and doors will help you save valuable time and money.

5. A more comfortable and quieter home

Your home should be a place where you can relax, but if you have older windows and doors, that’s not always the case. Investing in new windows and doors can help block out noise from outside, reduce dust and allergens and maintain your desired temperature, giving you a more comfortable and quieter home.

Vinyl replacement windows from Ostaco Windows & Doors

Benefits of Vinyl Replacement Windows

Vinyl windows have overwhelmingly become the go-to choice for today’s homeowner, because of their performance benefits and value. There are a few key reasons why vinyl windows are a great choice when considering upgrading or replacing:

1. Energy Efficiency

Vinyl windows are proven to be much more energy efficient than wood or aluminum windows, because of their design. Vinyl has cells (like a honeycomb) and is engineered to transfer hot and cold more gradually than a solid (like wood) or highly conductive material (like aluminum). Combine the performance of the vinyl frame with a LoE insulated glass unit and over time you will notice considerable savings on the heating and cooling your home.

2. Durable & Long-Lasting

Other window materials are too rigid, or absorb moisture. Vinyl is able to breathe and is much more pliable. Some windows will split or even separate in the corners when a home shifts, or even when there are fluctuations in the temperature. Vinyl windows are welded as a solid unit and are forgiving. They will hold up well in almost any kind of weather, from hot, humid summer days, to frigid and icy winter months. Vinyl will expand and contract just the same as your home.

3. Low Maintenance

Vinyl windows are one of the easiest types of windows to clean. Aside from wiping down the surfaces every spring, they require little to no maintenance. They won’t warp or crack, and do not need annual upkeep like other types of windows. They will continue to look as good as the first day you installed them.

4. Customizable & Affordable

Homeowners like choices, but also don’t want to break the bank. With vinyl windows you have the ability to select a particular style, or match a specific colour. The options to customize are almost unlimited, and can be made to fit any budget. Whether you are replacing a double-hung or casement, or any type of window in your home for that matter, there is a vinyl window solution for you. The design can be clean and linear as with modern homes, or ornate and detailed for a more classic look. You can spend as much or as little as you want to fit your design and functionality needs.

At Ostaco Windows & Doors, we design a wide selection of vinyl windows to suit your home. Find a dealer near you.

Questions for your window and door dealer from Ostaco

Top Questions To Ask Your Window & Door Dealer

Installing new windows and doors in your home can add style and boost your curb appeal — it  can even help to lower your utility bills. But choosing the right window and door dealer is essential for any installation process.

From choosing the windows and doors to the installation, make sure you are asking your window and door dealer these important questions:

Choosing Your Windows & Doors

1. What are the options for interior and exterior finishes?

Choosing your windows and doors begins with aesthetic considerations. Make sure you are aware of all of the finishes available, both inside and outside, and ask to see samples so you can choose the door that will help you achieve the right look.

2. How do the windows and doors operate?

Not all windows and doors open and close the same way. Double-hung windows open differently than casement windows, and sliding doors open differently than hinged patio doors. It will be important to understand exactly how the windows and doors you’re choosing will operate, as the architecture of your home or the layout of your furniture may impact your options.

3. Do the windows and doors adhere to fire safety?

One of the most important considerations for your new windows and doors are their safety features. Do they adhere to fire safety standards? How do they operate in an emergency? Do they have child safety locks? Asking these questions will help you and your family have peace of mind.

4. How much maintenance is required?

New windows and doors are likely to involve less maintenance than your old ones, but certain materials demand a higher level of maintenance after installation than others. Ask your dealer about the maintenance requirements of the windows and doors your are considering so you’ll know what to do after installation to keep them looking their best.

5. What product and service warranties are available?

New windows and doors almost always come with warranties, but what the warranties will cover can vary. Some warranties only cover certain aspects or features of the window, while others are more comprehensive. You’ll also want to ask your dealer about after-care service and what you can expect from them following your installation.

Questions To Ask About Installation

Choosing the right windows and doors is the first step, but it’s also important to ensure that you’re asking your dealer the right questions about the installation process.

1. Are there hidden fees in the installation cost?

Some window and door dealers don’t include certain costs in the installation quote. It’s important that you ask up-front if there are hidden costs so you’re not caught off-guard when the installation is completed.

2. What can I expect during the installation?

As with any renovation, you should ask your window and door dealer what you can expect during the installation process. How long will it take? What do you need to do to prepare? Knowing the answers to these questions will ensure that you and your installation team are on the same page from the beginning.

3. What kind of insurance or qualifications do they have?

While most window and door dealers and installers are reputable, there are a handful of underqualified companies. Be sure to ask your dealer if they have insurance so that your home is protected during the installation, and ask for qualifications so you know they’re legitimate.

4. Ask for references and reviews.

Many window and door dealers have an online presence, whether it’s a Facebook page or a website. Check out any reviews you can find (a quick Google search is sure to yield some reviews), or ask the dealer directly for references or referrals.

Windows Can Change The Look Of Your Home

Homeowners, and homebuyers for that matter, tend to overlook their windows. They are an afterthought, more a functional feature than an aesthetic one. Yes, windows contribute to your home’s energy efficiency, can be opened to let the summer breeze in, and keep out the cold, but that doesn’t mean they can’t look good too.

The fact is, your windows can have a dramatic impact on your home’s appearance. If you’re considering replacement windows, here’s how to change up the look of your home:

Vinyl Windows

Vinyl windows are the highest-selling residential window on the market, and for good reason. Ostaco windows are made to order, and can come in any shape, size, and colour — within reason of course. So whether you are a designer, architect, contractor, or DIY’er, you can have the window that fits your style. And unlike wood, you won’t have to repaint your new vinyl windows.

Window Styles

What are you looking for? Windows are everywhere, and we are sure you can recognize the differences, but never knew what to call them. If the traditional look appeals to you, double-hung or Single hung windows are the standard. Simply put, it looks like one large window divided into two sections called sashes. In the case of double-hung, both sashes can travel up and down, whereas with a single hung, only the bottom does. For the homeowner looking for a classic look.

If you were wanting to go modern, and needing to compliment that new stuccoed extension, casements or awning windows are the way to go. Clean hard lines maximize the amount of glass, which means more light, and large, unobstructed views. Like opening your windows to enjoy the fresh summer air? These windows open just like a door, hinging on either the left, the right, or top, bringing the great outdoors into your living space.

Without a doubt though, there is no better way to change the appearance of your home, and add some character to the interior than by adding a bow or bay window. Both styles of window add an interesting architectural detail to any facade. A bow window can be made to bend around the corner of your kitchenette, whereas a bay window will create a small seating area. Now imagine filling that nook with pillows, grabbing a book, your favorite hot beverage, and enjoying your new bay window. Sounds nice and comfy.

5 Signs You Need New Windows

Your windows are part of your home’s defence against the elements. But if your windows are starting to get old and are past their prime, they may be less effective in protecting your home.

Luckily, there are a few signs that you can watch for to know when it’s time to replace your windows:

1. Higher Than Normal Utility Bills

As windows begin to age, you may start to notice higher than normal utility bills. Over time, your windows may start to let in drafts and, as a result, lose more cold and warm air from your home. If you start to notice a steady rise in your utility bills and you know your windows are starting to age, consider replacing them. The investment will save you money in the long run!

2. Cold & Drafts

During the winter, you may feel cool gusts of air blowing into your home from the area around your windows. This is a tell-tale sign that your windows need to be replaced.

3. Windows Don’t Close Or Lock Properly

Windows aren’t just essential for keeping your home safe from the elements — they also play a major part in your home’s security. That’s why it’s important to ensure your windows always close and lock properly. Old casement windows may start to lose their ability to close if the window sash begins to droop, while others may lose their seal. If your windows no longer close and lock the way they should, consider a replacement as soon as possible.

4. Your Carpet Or Furniture Is Fading

Window glass is more than just regular glass. Window glass is made with reflecting properties that help to limit the amount of solar radiation that enters your home. Older windows may not have enough reflection, or it may have lessened over time, resulting in your furniture and carpet beginning to fade wherever the light hits. In this case, it may be time to replace your windows so you can protect your home’s interior and extend the life of your carpet and upholstered furniture.

5. The Window Glass Has Changed In Appearance

Over time, the finish on your windows may begin to change in appearance, whether it’s the colour of the finish or discolouration of the glass. While this is a normal chemical reaction, it is also a good indication that your windows may be getting old and needing to be replaced.

New windows bring a lot of value to your home, from helping you save money on utilities to adding to the curb appeal. If your home needs new windows, check out Ostaco’s gallery for some inspiration.
