FAQs

At BM Windows and Doors, we know choosing the right windows can bring up a lot of questions.

That’s why we’ve put together this helpful FAQ section—so you can get clear, straightforward answers.

Casement Window Questions

A casement window is a side-hinged window that opens outward using a crank handle. It typically opens like a door, swinging to the left or right, which allows for full top-to-bottom ventilation and easy operation.

Why choose casement windows for my home?

Casement windows are a popular choice for many homeowners because they offer:

Excellent ventilation – they open fully to let in maximum fresh air.
Tight seals – when closed, they compress tightly against the frame for superior energy efficiency.
Unobstructed views – the single sash design means no middle bar to interrupt your view.
Easy operation – ideal for hard-to-reach areas like over the kitchen sink.

How do RevoCell® casement windows stand out?

RevoCell^® casement windows from Nordik offer all the benefits of traditional casement windows, plus exclusive innovations:

Microcellular PVC construction – stronger than hollow vinyl and better insulated.
Energy efficiency – outstanding thermal performance helps reduce energy bills.
Built to withstand the elements – resist warping, cracking, and fading in harsh climates.
Slimmer frames, bigger glass – more natural light without sacrificing performance.
Low maintenance – no painting or rotting; long-lasting clean appearance.
Fully fusion-welded corners – for superior strength and airtight sealing.

Absolutely. Casement windows are versatile and work well in almost any space—especially in areas where you want more ventilation or a wide, unobstructed view. They’re perfect for living rooms, bedrooms, kitchens, and basements.

Are casement windows secure?

Yes. Casement windows use a multi-point locking system that secures the sash at several points along the frame. RevoCell^® windows enhance this security with strong materials and tight seals for added protection.

What sizes do casement windows come in?

RevoCell® casement windows are custom-manufactured to fit your home’s exact dimensions. Whether you need a small window for a bathroom or a large one for a scenic view, Nordik can make it to fit.

Can I customize the look of my casement windows?

Yes! You can choose from a variety of exterior colors, grille designs, and hardware finishes to match your home’s style.

Slider Window Questions

What is a slider window?

A slider window (also known as a horizontal slider) features one or more sashes that slide horizontally along a track. They’re simple to operate and great for wide window openings where you want an unobstructed view and ventilation.

Where are slider windows typically installed?

Slider windows are commonly used in living rooms, bedrooms, and basements—anywhere you want easy operation, natural light, and a modern appearance. They’re ideal for openings that are wider than they are tall.

What makes RevoCell® slider windows better?

How do slider windows open and close?

Can slider windows be removed for cleaning?

Yes! RevoCell® slider windows feature tilt-in or lift-out sashes, making it easy to clean both sides of the glass from inside your home—no ladder required.

Do slider windows provide good ventilation?

Yes, especially double-slider models which allow airflow from both sides. They’re perfect for rooms where you want consistent, cross-room ventilation without sacrificing ease of use or view.

Are slider windows a good choice for basements?

Slider windows are an excellent option for basements thanks to their horizontal design, which fits well in wider, shorter openings. RevoCell® sliders also offer better insulation and low-maintenance durability in below-grade conditions.

Hung Window Questions

What is a hung window?

Hung windows are vertical sliding windows that come in two main styles: single hung (only the bottom sash moves) and double hung (both the top and bottom sashes move). They’re a timeless, space-saving choice for many areas of the home.

Where are hung windows typically used?

Hung windows are popular in bedrooms, bathrooms, and living spaces. Their vertical operation makes them ideal for tighter exterior spaces like walkways or patios where a window that swings outward might not work.

What makes RevoCell® hung windows better?

RevoCell^® hung windows are built with solid-core microcellular PVC, offering next-level performance and durability:

Superior insulation from the solid-core frame, minimizing heat transfer and improving energy efficiency.
Fusion-welded corners for airtight performance and long-term durability.
Slim profiles for a larger glass area and enhanced natural light.
Low-maintenance finish that won’t rot, crack, or peel over time.
Smooth sash movement with reinforced hardware and balance systems.

Are RevoCell® hung windows energy-efficient?

What is the difference between single hung and double hung windows?

Single hung – Only the bottom sash moves; the top sash is fixed.
Double hung – Both sashes move up and down for improved airflow and easier cleaning.

Double hung windows are often preferred for upper floors and areas where cleaning both sides from the inside is a plus.

Do hung windows tilt in for cleaning?

Yes, both single and double hung RevoCell® windows feature tilt-in sashes, allowing you to clean the exterior glass safely and easily from inside your home.

How secure are RevoCell® hung windows?

Very secure. RevoCell® hung windows include a multi-point locking system and reinforced sashes that resist forced entry. The durable mPVC construction adds an extra layer of protection.

Are hung windows easy to maintain?

Absolutely. Just occasionally clean the glass and vacuum the tracks. The tilt-in sashes make cleaning effortless, and the solid-core frame means no sanding, painting, or sealing is ever needed.

Can I customize my hung windows?

Yes. Nordik offers a wide variety of customizations, including grille patterns, exterior and interior color finishes, hardware options, and energy-efficient glazing.

Do hung windows provide good ventilation?

Double hung windows are excellent for ventilation, especially when both sashes are open—warm air escapes through the top and cool air enters through the bottom. Single hung windows offer great airflow as well but with one operable sash.

Are hung windows a good choice for small rooms?

Yes! Hung windows are perfect for compact spaces because they open vertically without protruding outward. They’re also ideal for walkways, patios, and areas with limited exterior clearance.

Bay / Bow Window Questions

What is a bay window?

A bay window is a combination of three or more windows that project outward from the exterior wall of a home. They typically include a large fixed center window flanked by two operable windows, often casement or hung styles, set at angles to create a wide viewing area and additional interior space.

Where are bay windows commonly installed?

Bay windows are often installed in living rooms, dining rooms, or master bedrooms. They are perfect for creating cozy reading nooks, extra seating, or simply enhancing curb appeal with their distinctive architectural style.

Do bay windows provide ventilation?

Yes, all the units of a bay window can be operable (typically casement or hung), allowing fresh air to flow into your home. You get both wide views and excellent ventilation, especially when the flanking windows open.

How are bay windows supported?

Bay windows are structurally reinforced to project safely from your home. Depending on size and weight, support options may include a head board, seat board, and sometimes external braces or a roof overhang for added stability and insulation.

Are bay windows difficult to maintain?

Not at all. RevoCell® bay windows are built for longevity and minimal maintenance. The solid-core PVC resists fading, rotting, and warping, while the operable sashes are easy to clean from the inside thanks to tilt-in and crank mechanisms.

Can bay windows help with natural lighting?

Definitely. Bay windows extend outward, allowing more natural light to enter from multiple angles. This helps brighten up your space and creates a more open, airy feel indoors.

What is the difference between and bay window and a bow window?

The key difference between bay and bow windows is the shape and number of windows. Bay windows typically consist of three windows (one large fixed center window with two smaller operable windows), creating a more angular projection. Bow windows, on the other hand, feature a curved design made up of four or more windows, offering a gentler, more rounded look. Both options provide extra space, light, and stunning views, but the choice depends on your home’s aesthetic and your preference for a sharp or curved projection.

Fixed / Picture / Custom-Shaped Window Questions

What are fixed or picture windows?

Fixed or picture windows are non-operable windows designed to provide an unobstructed view and allow natural light into your home. Since they don’t open, they offer excellent energy efficiency and are perfect for showcasing outdoor views.

What are custom-shaped windows?

Custom-shaped windows come in a variety of unique geometric styles—such as arches, circles, triangles, and more—tailored to fit specific architectural designs or add a distinctive look to your home. They are typically fixed but can be combined with operable windows in a custom configuration.

What are the benefits of RevoCell® fixed and custom windows?

RevoCell^® windows bring exceptional quality to fixed and custom designs:

Superior energy efficiency thanks to the microcellular solid-core PVC and fusion-welded construction.
Highly customizable shapes, sizes, grille options, and finishes.
Maximum daylight and views due to ultra-slim frames and large glass areas.
Maintenance-free performance that resists warping, fading, and cracking.
Complementary designs that can be paired with operable windows for ventilation where needed.

Can I use fixed windows in combination with other window types?

Yes! Fixed windows are often combined with casement, awning, or hung windows to create a custom look with both light and ventilation. This is ideal for large openings or feature windows in living rooms, stairwells, or entryways.

Do fixed and custom-shaped windows improve energy efficiency?

Absolutely. Since they do not open, fixed and picture windows have fewer points of air leakage. When built with RevoCell® solid-core technology and ENERGY STAR® certified glass, they significantly reduce heat transfer and help maintain indoor comfort.

Are custom-shaped windows more expensive?

Custom-shaped windows can be more expensive than standard rectangular windows due to the specialized manufacturing and design work. However, they add unique character and curb appeal that may enhance your home’s value. The best way to find out is to contact us for a personalized quote.

Can fixed windows be installed in any room?

Yes, fixed and picture windows work well in any room where you want natural light and a clear view without needing to open the window. They’re especially popular in living areas, staircases, and as accent windows in high or hard-to-reach spaces.

How do I clean fixed or custom-shaped windows?

Cleaning is easy! Since they don’t have hardware or moving parts, fixed windows have fewer areas that collect dust. For hard-to-reach custom shapes, a telescopic window cleaning tool can help. The durable, low-maintenance RevoCell® frames also resist staining and buildup.

Are RevoCell® fixed windows available in different colors and finishes?

Yes. RevoCell® custom and fixed windows are available in a variety of interior and exterior colors and finishes to match your style. You can also choose between different grille patterns and decorative glass options.

Do fixed windows provide any sound insulation?

Yes. Because fixed windows are sealed and non-operable, they provide excellent noise reduction. When built with RevoCell® frames and multi-pane glass, they help keep your home quieter and more peaceful.
