Thinking about replacing your patio door or looking to install one in a new home? There are plenty of patio door options to consider – whether it's aesthetics, functionality, security, energy efficiency, or costs. Here are some tips to help you get exactly what you are shopping for.

Blending indoor and outdoor spaces

In the world of modern home design, the art of seamlessly blending indoor living spaces with the natural beauty of the outdoors has become a remarkable and sought-after achievement. At the very core of this architectural harmony lies the invention of sliding patio doors. These versatile and stylish additions have rightfully earned their place as the preferred choice for homeowners who seek both functionality and aesthetics.

Crafted from an array of diverse materials such as wood, vinyl, fibreglass, aluminum, and clads, sliding patio doors open up a world of possibilities and offer a wide spectrum of benefits, ultimately transforming living spaces into serene and inviting retreats.

Sliding patio door configurations

Patio Door Configuration

The true versatility of sliding patio doors is magnificently showcased through their ability to cater to a multitude of configurations, ensuring a perfect match for every individual's preferences:

Standard sizes

A plethora of standard-sized/configuration options, including 2-panel, 3-panel, and 4-panel widths, are readily available from various manufacturers. While these options provide practical solutions, it's essential to bear in mind that certain features like blinds and triple glazing might be limited by standard sizing.

Standard window sizes

Custom sizes

For those seeking a sliding patio door configuration that exceeds standard width and height, custom-designed options are available to meet your specific needs. These premium solutions, which may include transoms or multiple panels, typically come at a higher investment—potentially up to twice the cost of a standard configuration. Additionally, in-the-glass blind options for custom-sized sliding patio doors are generally limited in availability.

If your replacement patio door opening is 4–8 inches wider than a standard size and you're looking for a cost-effective solution, consult your sales representative about options to adjust the opening. By finishing the interior with wider moulding and the exterior with wider capping, you can achieve a seamless look while reducing the need for a custom-sized door.

Transom vs. full height

If you're replacing a patio door with a transom above it, consider alternative options that can enhance shading, ventilation, and energy efficiency. These include tinted glass, triple glazing, or replacing the transom with an awning window for improved airflow and insulation.

Another option to consider is forgoing the transom in favour of a taller sliding door. While this may reduce the cost of the door itself, it’s important to note that a taller door will be heavier, potentially leading to increased wear on the rollers over time. Additionally, you may need to update your existing window coverings. Keep in mind that triple glazing and interior blinds are generally not available for door heights exceeding 79.5 inches.

Choose a door with a low-profile threshold: A low-profile threshold not only adds to the door's aesthetic by creating a cleaner look but also improves accessibility for those with mobility issues. It's especially important if you’re planning to install the door for elderly or young children who may struggle with higher thresholds.

Security

Modern sliding patio doors are designed to provide advanced protection without compromising style or functionality. Engineered with multi-point locking systems, reinforced frames, and impact-resistant glass, these doors offer enhanced security against forced entry. Additional features such as anti-lift mechanisms, security bars, and laminated glass further strengthen protection. For added peace of mind, optional smart lock technology allows for remote monitoring and control, ensuring your home remains secure while maintaining a sleek and sophisticated appearance.

Single-point Locks

Standard locks from most manufacturers lock up rather than down (an anti-lift deterrent).

Single-point locks

Kick Locks or Security Bolts

Manufacturers have ingeniously integrated features such as kick locks or security bolts, which can be standard components or optional add-ons, offering homeowners an added layer of security.

Deadbolt lock

Keylocks

Keylocks can be installed both inside and outside the patio door – check with the manufacturer if you want both.

Keylocks

Multi-Point Locking Systems

As an advanced security measure, multi-point locking systems engage multiple points along the door frame, resulting in an impressively robust protection barrier.

Multi-point locks

Reinforced Metal Sashes

To further enhance security, the incorporation of reinforced metal sashes within the door frame adds a substantial boost to the overall structural integrity of the door.

Safety Glass Variants

The availability of safety glass variants, such as tempered and laminated glass, adds an extra dimension to security measures, fortifying the door against potential break-ins and ensuring peace of mind for homeowners.

Weatherproofing and energy efficiency

The contemporary sliding patio door has embraced a commitment to climate resilience and energy efficiency, accomplished through features that can withstand the elements while also conserving energy:

Weatherproofing Innovations

The incorporation of innovative elements like sloped sills and meticulously engineered weather stripping ensures that the interior environment remains comfortable, even when faced with adverse weather conditions.

Advanced Glass Solutions

Beyond the confines of standard glass, the options of double or triple glazing and specialized coatings empower homeowners with control over light, temperature, and energy consumption. Some variants even boast enhanced sound insulation properties, creating a cocoon of tranquility within.

Materials

Sliding patio doors come in a variety of materials, each offering unique advantages to suit different needs and preferences. Here’s a closer look at some of the most popular options:

Vinyl

Vinyl sliding patio doors are renowned for their energy efficiency, low maintenance, and cost-effectiveness. They offer a practical solution for homeowners, providing excellent thermal insulation and durability while being resistant to the elements. Vinyl doors are easy to care for, making them a popular choice for those looking for a hassle-free, affordable option.

Fibreglass

Fibreglass sliding patio doors boast exceptional durability and weather resistance, making them ideal for homes in areas with extreme weather conditions. These doors can mimic the charm of wood, offering the aesthetic appeal of natural materials without the associated upkeep. Their resilience makes them a long-lasting investment for homeowners seeking performance and style.

Aluminum

Aluminum sliding patio doors are known for their lightweight nature and durability. They offer a sleek, modern look while being resistant to corrosion and humidity, ensuring long-lasting performance. Aluminum doors are a great choice for contemporary designs and homes in regions with varying climate conditions.

Clads

Clad sliding patio doors combine multiple materials, offering the best of both worlds in terms of performance and aesthetic appeal. These doors typically feature a durable exterior (often metal or fibreglass) combined with a wooden interior, providing excellent insulation and low-maintenance benefits alongside the warmth and beauty of wood.

Wooden

Wooden sliding patio doors bring timeless elegance to any home. Beyond their aesthetic appeal, they offer natural insulation properties, making them an energy-efficient option. Wooden doors are highly customizable, allowing homeowners to stain or paint them to match their decor, adding a unique touch to the home.

Steel

Steel sliding patio doors are known for their strength and security. These doors are particularly well-suited for modern or industrial-style homes, offering an added sense of protection and durability. Steel doors are ideal for homeowners seeking robust security without sacrificing style.

tip-lightbulb

Consider sliding door materials based on climate: In extreme climates like Ottawa’s, opting for fiberglass doors can offer superior insulation and resistance to weather. Vinyl doors are a cost-effective choice, offering good thermal performance and low maintenance. Aluminum, while sleek, may require additional insulation for better energy efficiency in harsh temperatures.

Ultimately, the choice of material for your sliding patio door comes down to a balance of aesthetics, performance, and maintenance. While vinyl doors are low-maintenance and cost-effective, materials like fibreglass, steel, and wood may require more upkeep but offer higher performance or unique design benefits. Consider your climate, security needs, and long-term maintenance preferences when making your decision.

Framing

Not all frames are created equal, and while it may not seem significant at first, the frame plays a crucial role in durability and energy efficiency. A well-insulated, high-quality frame is essential. Look for a multi-chambered design to enhance structural integrity and minimize thermal exchange. Additionally, aluminum reinforcement helps maintain strength and prevents sagging over time, ensuring long-term performance.

Glass innovations

Glass sliding patio doors create a seamless connection between indoor and outdoor spaces, flooding your home with natural light and offering unobstructed views of the outdoors. This design enhances the beauty of your home while strengthening your connection to scenic surroundings. Current glass technology offers a wide range of options, allowing homeowners to tailor their doors with various thicknesses, coatings, tints, and glazing to create the perfect ambiance. Whether you are seeking enhanced privacy, energy efficiency, or a touch of elegance, there’s a glass solution to suit every need.

Integrated mini-blinds

A standout feature of modern sliding patio doors is the integration of mini-blinds within the glass panes.

Grills, hardware, screens, and colour

Customisation for sliding patio doors goes beyond functionality — it's an opportunity to transform your space and infuse it with style. From intricate details to finishing touches, every aspect of the design can be tailored to match a unique vision.

Grilles with Character

Optional grille designs, such as Colonial or Prairie, bring architectural sophistication to your sliding doors. These classic patterns add visual interest while enhancing the overall charm of the space, offering a subtle yet impactful nod to traditional design.

Sophisticated Hardware

Handles and locks are not just functional elements — they’re key to elevating the door aesthetic. Choose from sleek white or bold black finishes to complement your interior decor and create a cohesive look that ties together the door’s design with your home's overall style.

Seamless Screen Integration

Durable screens are essential for maintaining a connection between indoor and outdoor living, and their design should reflect your tastes. Available in a range of colours and materials, screens integrate smoothly with your sliding door’s appearance while providing unobstructed views and keeping insects at bay.

Exterior Colours

Colour is a fundamental facet of personalisation. Exterior colour palettes vary with the type of material and typically offer more options than interior colours. For instance, wooden sliding doors provide a broad spectrum from deep hues to natural wood stains, creating a lasting impression from the outside. Aluminum doors offer a selection of 10 to 30 powder-coated, typically earthy colours, adding a modern and vibrant touch. Vinyl doors are generally available in 8 to 10 standard exterior colours through vinyl spray or laminate finishes.

Interior Customization

Patio door interiors come in various finishes to match your home’s décor. While white is the standard colour, many manufacturers offer customizable options. Wooden doors can be stained or painted to complement interior trim and furnishings. Vinyl doors often feature faux wood finishes or paintable and stainable surfaces to achieve a natural wood look or match your preferred colour. Aluminum doors are typically white inside but may have select colour options. Whether you prefer the warmth of wood, the elegance of simulated finishes, or the sleek durability of vinyl, there’s a style to suit your space. To ensure lasting beauty, check the manufacturer’s colour warranty - There is a difference.

Warranty

Labour & Materials

Some companies offer lifetime labour and materials warranty while others may charge extra for materials and charge by the hour for labour.

Installation, maintenance, smart homes
