FAQ Category
Residential Windows
Are Morrison windows custom made?
Yes. Morrison manufactures residential vinyl windows to suit project and opening requirements rather than limiting customers to a small set of stock dimensions. Available sizes, configurations and performance limits vary by product series.
Do you manufacture windows for both renovations and new construction?
Yes. Morrison supplies window systems for renovation, replacement, new-construction and multi-family applications. Some series are specifically positioned for renovation work, while others can be configured for different installation conditions.
What is the difference between a casement window and a slider window?
A casement window is hinged and opens outward, allowing the sash to close against compression-style weather seals. A slider moves horizontally within the frame and does not project outward, which can be useful beside decks, walkways or other areas where exterior clearance is limited.
Which Morrison window series are casement or awning style?
The residential catalogue includes casement and awning families such as the 400, 4007, 762 and 775 Series. The best choice depends on the installation type, desired frame profile, glazing requirements and project goals.
Which Morrison window series are sliding style?
The residential catalogue includes slider families such as the 500, 508 and 550 Premium Series, with additional product families shown in the residential catalogue as they become available.
Can fixed windows be combined with operable windows?
Yes. Many projects combine operable casement, awning or slider units with fixed or picture windows to balance ventilation, view and architectural composition. Available combinations depend on the selected series and opening size.
Can Morrison make bay, bow or special-shape windows?
Several residential window families can be coordinated with fixed, picture, bay, bow or special-shape configurations. Feasibility depends on dimensions, glass, structural requirements and the selected product family.
Do you offer window screens?
Screens are available with applicable operable window and door products. Screen type, colour and configuration should be confirmed for the specific series and opening.
How do I choose between the 400, 500, 550, 762 and 775 Series?
Start with how you want the window to operate, whether the project is renovation or new construction, the desired sightline, glass package and performance requirements. The product pages explain the main differences, and Morrison can help narrow the choice once the opening and project requirements are known.
FAQ Category
Glass, Energy & Design Options
What glass options are available?
Depending on the product series, insulated glass can be configured with Low-E coatings, argon gas and different insulated-glass thicknesses. Decorative glass, grille patterns and other options may also be available. Confirm the final glass package for the selected product and project.
What does Low-E glass do?
Low-emissivity (Low-E) coatings are designed to manage heat transfer through the glazing. Different Low-E coatings can be selected to balance insulation, solar heat gain and visible light for the orientation and goals of a project.
What is argon gas in an insulated glass unit?
Argon is an inert gas commonly used between panes of insulated glass to improve thermal performance compared with air-filled cavities. The exact benefit depends on the complete glass make-up and window system.
Do you offer different Low-E coating choices?
Morrison product literature includes multiple insulated-glass options for different solar-control and thermal-performance goals. The appropriate coating should be selected based on orientation, climate, comfort priorities and project requirements.
Can I choose different frame colours?
Yes. Interior and exterior colour choices are available across applicable residential products, and commercial aluminum systems can be supplied in standard anodized or mill finishes with custom painted finishes available for many applications. Availability varies by system.
Do you offer grilles between the glass?
Grille patterns are available with applicable residential window and door products. Pattern, colour and compatibility should be confirmed for the selected series and glass configuration.
Why does condensation sometimes appear on windows?
Condensation can occur when warm, humid indoor air meets a colder surface. Indoor humidity, outdoor temperature, glass performance, air circulation, window coverings and installation conditions can all influence condensation. It does not automatically indicate that a window has failed.
Can you recommend a window based only on U-value?
U-value is important, but it is only one part of product selection. Air leakage, solar heat gain, glass choice, operation, installation, orientation, comfort and project-specific code requirements should also be considered.
FAQ Category
Residential Doors & Large Openings
What residential door systems does Morrison offer?
The residential catalogue includes sliding patio doors, multi-slide configurations, lift-and-slide systems, folding sliding doors and swing/French-door families.
What is the difference between a standard sliding patio door and a multi-slide door?
A conventional patio door typically uses a smaller number of panels in familiar sliding arrangements. Multi-slide systems use additional or larger panels to serve wider openings and create more flexible architectural layouts.
How does a lift-and-slide door work?
Turning the operating handle lifts the active panel slightly away from its seals before it slides. This reduces operating resistance for large panels. When the door is closed, the panel returns to its sealing position.
How does a folding sliding door work?
Multiple connected panels fold and stack toward one or both sides of the opening. This can clear a much larger percentage of the opening than a conventional slider and create a strong indoor-outdoor connection.
Are folding doors only for very large homes?
No. Folding systems can be useful anywhere a wider clear opening and indoor-outdoor connection are design priorities. The practical panel count, size and configuration depend on the opening and project conditions.
Can large-opening doors include a convenient everyday access panel?
Some folding and multi-panel configurations can be planned so normal day-to-day access does not require opening the complete system. The exact arrangement depends on the selected door and panel configuration.
Can patio and large-opening doors use energy-efficient glass?
Applicable residential door systems can be configured with insulated glazing appropriate to the product. Glass thickness, Low-E coating, gas fill and size limits should be confirmed for the chosen system.
FAQ Category
Skylights & Daylighting
What is a curb-mount skylight?
A curb-mount skylight installs over a raised roof curb prepared as part of the roof assembly. Morrison offers curb-mount daylighting options in fixed and venting configurations.
What is the difference between a fixed and venting skylight?
A fixed skylight is designed primarily to bring daylight into the space. A venting skylight can also open to provide natural ventilation. Manual and powered operation may be available depending on the model.
What is a sun tube?
A sun tube is a compact daylighting system that captures light at roof level and transfers it through a reflective tube to a ceiling diffuser below. It can be useful in halls, bathrooms, closets and interior areas where a conventional window or large skylight is impractical.
When should I consider a sun tube instead of a skylight?
A sun tube can be a good option when the goal is daylight rather than a roof view, when roof or ceiling space is constrained, or when a smaller roof opening is preferred. A skylight provides a larger daylight opening and, in venting models, can also provide ventilation.
FAQ Category
Commercial Glazing Systems
What commercial aluminum systems are available through Morrison?
The commercial offering includes curtain wall, storefront, commercial entrance doors, thermally broken operable vent windows and drainable louvers for commercial building applications.
What is the difference between storefront and curtain wall?
Storefront is generally a shallower framing approach commonly used at ground-floor commercial entrances, retail façades and interior glazing. Curtain wall is a building-envelope system designed for larger exterior glazed façades and incorporates drainage, pressure equalization and structural design considerations appropriate to the system. Final selection should follow the project drawings and specifications.
What curtain wall systems are available?
The commercial catalogue includes the 2000 non-thermal curtain wall and the 3000 thermal curtain wall family. The 2000-T thermally improved curtain wall is currently in final development; contact the commercial team for current availability and project timelines. Each system has different depth, thermal and application characteristics, so project specifications should guide selection.
What does the 2000-T curtain wall offer?
The 2000-T is a 2-inch sightline thermally improved curtain wall in final development, with a 4-inch back section and approximately 6-inch overall depth. It is designed around 1-inch dual-glazed infill, concealed shear-block joinery, a continuous gasket thermal break and pressure-equalized rainscreen principles. Validation testing and technical documentation are still in progress.
What storefront systems are available?
Commercial storefront options include thermal and non-thermal systems. The thermal T451 storefront uses a 2-inch sightline and 4-1/2-inch frame depth for 1-inch glazing infill. The non-thermal 450 storefront uses a streamlined 1-3/4-inch by 4-1/2-inch profile for 6 mm glazing infill.
When would a thermal storefront or curtain wall be considered?
Thermal systems are generally considered where energy performance, interior comfort or condensation resistance are important project requirements. The final system must still be selected to satisfy the architectural drawings, specifications, code requirements and project-specific engineering.
What commercial entrance doors are available?
Commercial entrance systems include the 400T thermally broken medium-stile door as well as Series 200 narrow-stile and Series 300 medium-stile non-thermal doors.
What are the main dimensions of the 400T Thermal Door?
The 400T uses a 3-1/2-inch (88.9 mm) medium vertical stile and a 2-1/4-inch (57 mm) door depth, with 4-inch, 7-1/2-inch and 10-inch bottom-rail options. It can accommodate 1-inch double glazing and 1-1/2-inch triple glazing, subject to the approved door configuration.
What is the difference between Series 200 and Series 300 non-thermal doors?
Series 200 is the narrow-stile option with a slimmer vertical stile, while Series 300 is the medium-stile option with a wider, more substantial profile. Both are non-thermal commercial entrance-door systems and can be selected based on appearance, hardware and project requirements.
Can commercial vent windows integrate with storefront and curtain wall?
Yes. The 8000 Series is a thermally broken operable vent window designed for integration with storefront and curtain wall using appropriate subframes. It uses a polyurethane pour-and-debridge thermal break, overlap vent construction, rigid corner-key joinery and 1-inch glazing infill.
Are the 8000 Series vent windows performance tested?
Published product information identifies structural, air and water testing for the 8000 Series. Project teams should use the applicable current test reports and approved product configuration when confirming project requirements.
What is a drainable louver?
A drainable louver is designed so its blades collect and direct water toward the jambs and sill while allowing ventilation through the assembly. The commercial 2-inch drainable louver is designed to integrate with curtain wall or storefront systems.
What are the basic features of the 2-inch drainable louver?
The system uses a 2-inch-deep extruded aluminum frame, 2-1/2-inch blade spacing and concealed screw-spline blade attachment. Published product information also identifies bird-screen or blank-off-panel options and an 8-inch by 8-inch minimum size.
Can commercial systems be supplied in different finishes?
Commercial aluminum systems are available in system-specific standard finishes such as clear anodized, black/dark-bronze anodized and mill finish, with custom painted finishes available for many products. Custom finishes can require additional lead time.
Can commercial doors, vents and louvers integrate into the framing systems?
Many of the commercial systems are designed as coordinated families. Doors, vent-window subframes and louvers can be integrated with applicable storefront or curtain wall assemblies, but compatibility should be confirmed against the specific system details and project requirements.
