If you have been looking at ways to make your deck, patio, pergola, or outdoor living area more comfortable through Alberta’s summer months, you have probably come across two products that keep appearing in the conversation: power screens and side guide blinds. Both block UV radiation. Both provide shade and privacy. Both are available in various fabric opacities to suit different sun-blocking needs. But they are different products with different mechanisms, different strengths, and different use cases, and choosing the wrong one for your space means spending money on something that does not quite fit what you needed.
At Canfab Products, we fabricate and install both power screens and side guide blinds for Edmonton homeowners, and we answer the question of which one is better on a regular basis. The honest answer is that it depends on your space, how you use it, and what you are primarily trying to achieve. This guide breaks down both products clearly so you can make that call with confidence before you commit.
What Are Power Screens?
Power screens are motorized retractable screen systems that deploy and retract at the push of a button or remote control. The screen fabric rolls down from a housing mounted above the opening, guided by a track system on either side that keeps the fabric taut and the edges sealed as it descends. When fully extended, the screen creates a full-width barrier across the opening that blocks UV radiation, filters direct sunlight, keeps insects out, and provides a degree of privacy while maintaining visibility through the mesh fabric.
The motorized operation is the defining characteristic of power screens and what distinguishes them from manual screen alternatives. A power screen covering a large patio opening or a floor-to-ceiling window can be deployed or retracted in seconds without any physical effort, which makes it practical to adjust the screen multiple times throughout the day as the sun angle and your preferences change. For homeowners with larger openings or with accessibility considerations, this ease of operation is a significant practical advantage.
Power screens are available in a range of mesh fabrics with different openness factors, meaning different proportions of the fabric surface that are open to airflow. A tighter weave with a lower openness factor provides more UV blockage and more privacy but reduces airflow and visibility. A more open weave lets more air and light through while still blocking the most intense direct UV radiation. Canfab Products helps homeowners select the right fabric specification based on the orientation of the space, the intensity of sun exposure, and the balance of shade, airflow, and visibility they are looking for.
What Are Side Guide Blinds?
Side guide blinds are fabric shade systems that deploy vertically in a guided track on either side of the opening, held in position by a locking mechanism that allows the blind to be set at any height and locked in place against wind movement. Unlike power screens which roll down from a top-mounted housing with a motor, side guide blinds are typically operated manually, pulling the fabric down from the roll and securing it at the desired position using the built-in lock.
The built-in lock is the key distinguishing feature of side guide blinds and what makes them particularly well suited to open-sided spaces like pergolas, deck posts, and outdoor structures where wind is a consideration. A side guide blind locked in position stays put in moderate wind conditions without flapping or billowing, which is the failure mode of many simpler outdoor shade solutions that use straps or ties rather than a proper locking track.
Side guide blinds are available in the same range of fabric types as power screens, from open-weave solar meshes that filter UV while maintaining views, to denser privacy fabrics that provide a more complete visual barrier. The fabric choice significantly affects how the blind performs in terms of airflow, visibility, and sun protection, and selecting the right fabric for the specific orientation and use case of each blind is as important as the product selection itself.

| Investment | Higher — motor and track system adds cost | Lower upfront — simpler mechanism |
When Power Screens Are the Better Choice
Large Openings That Would Be Impractical to Operate Manually
Power screens come into their own on large openings where manual operation would be physically demanding or awkward. A screen covering a four to six metre wide patio opening or a full-height glass wall is simply more practical to operate with a motor than with manual effort, particularly if the opening needs to be adjusted frequently throughout the day. The motor handles the weight of the fabric effortlessly and deploys or retracts the full width of the opening simultaneously in a smooth, consistent action that manual systems cannot match at large scales.
Patios and Balconies Where Insect Control Matters
Power screens with a sealed track system on both sides create a more complete perimeter seal around the opening than most side guide blind configurations, which means they are more effective at keeping insects out while still allowing air movement through the mesh fabric. For homeowners who want to sit on their deck in the evening without mosquitoes or other insects, a properly fitted power screen provides meaningful insect control alongside its UV and shade functions. This combination of insect protection and sun screening with motorized convenience makes power screens a popular choice for deck and patio applications across Edmonton’s summer season.
Windows and Glass Doors Facing Intense Afternoon Sun
Power screens installed over south and west-facing windows and glass doors intercept solar heat gain before it reaches the glass, reducing the interior temperature rise that drives air conditioning energy use during Alberta’s summer afternoons. Because they deploy and retract automatically or at the touch of a button, they can be easily adjusted as the sun position changes through the day without interrupting whatever is happening inside the home. A homeowner who wants to block the afternoon sun but allow morning light can deploy the screen in the early afternoon and retract it in the evening without thinking about it.
When Side Guide Blinds Are the Better Choice
Open-Sided Structures Like Pergolas and Covered Decks
Side guide blinds are particularly well suited to pergolas, covered patios, and outdoor structures where the shade system needs to be mounted on posts or side walls rather than in a framed opening with a header. The guided track and locking mechanism allows a side guide blind to function effectively on a freestanding post installation in a way that power screen track systems are typically not configured for. The ability to lock the blind at a specific height and have it stay reliably in position through moderate wind makes side guide blinds the practical choice for these open structural applications.
Multiple Narrower Openings Where Motor Cost Per Opening Is High
A pergola or deck with multiple defined bays or openings between posts may benefit more from side guide blinds than from individual motorized power screen systems because the cost of motorizing each opening individually adds up quickly. Side guide blinds provide comparable shade and privacy performance at a lower per-opening cost, and the manual operation is entirely practical on smaller openings that can be reached easily and adjusted without significant physical effort. When budget is a consideration and the openings are not so large as to make manual operation inconvenient, side guide blinds represent genuinely strong value.
Spaces Where Wind Resistance in the Extended Position Matters
While power screens retract when winds become strong to protect the mechanism, side guide blinds with their built-in locking system can remain extended in moderate wind conditions without damage. For homeowners who want shade protection that stays in position through the variable breezes of an Alberta summer afternoon without needing to retract and redeploy as conditions change, side guide blinds offer more flexibility in how they are managed across changing weather conditions.
Fabric Selection: What Both Products Have in Common
Whether you choose power screens or side guide blinds, the fabric selection is the decision that most directly affects how the product performs in your specific space. Canfab Products supplies both products in a range of fabrics with different openness factors and sun-blocking values, and selecting the right fabric is as important as the product choice itself.
For spaces that face intense afternoon sun and where the primary goal is to reduce heat and glare while maintaining a view through the screen, an open-weave solar fabric with an openness factor in the range of five to ten percent provides good UV filtering while keeping the space feeling open and bright. For spaces where privacy is a higher priority alongside sun control, a denser fabric with a lower openness factor or a semi-opaque privacy fabric provides more complete visual separation while still allowing some natural light to filter through.
Insect screen mesh is a separate category of fabric used primarily in power screen applications where the goal is to keep insects out while allowing maximum airflow. This fabric provides minimal solar shading but keeps the space insect-free, making it ideal for evening use in screened-in deck or patio applications.
Can You Use Both?
Absolutely, and many Canfab Products clients do exactly that. A common configuration for a large outdoor living area is power screens on the primary south or west-facing opening where motorized convenience and insect control are priorities, combined with side guide blinds on secondary openings between pergola posts or on side elevations where the structural situation suits a guided blind better than a framed screen system.
The two products use compatible fabric ranges and are available in coordinating colours and finishes, so combining them in the same outdoor space does not create an aesthetic mismatch. Canfab Products designs installations that treat the outdoor space as a complete system and specifies each product where it fits best rather than defaulting to a single solution across the entire space.
