01 · Lift + slide
Watch the panel lift, then slide.
The handle does the work: it raises the panel clear of its seal, the panel slides, and closing the handle lowers it back into the seal.
LIFT + SLIDE · SLIDING FAMILY
Open a wall.
Keep the envelope.
Wide glass panels move with a turn of the handle, then settle back into a firm perimeter seal. Choose Lift + Slide for expansive openings or Easy Slide for a simpler, smaller-format sliding door.

HOW LIFT + SLIDE MOVES
How a lift + slide door works
One handle controls the whole movement.
Turn, move, and settle the panel back into its seal. The sequence is simple enough to understand at a glance.
Lift
Turn the handle to lift the operable panel off the track.
Slide
With the panel lifted, slide it to open the passage.
Seal
Return the handle to lower the panel into its closed position.
THE DIFFERENCE IS IN THE FIRST TURN
Lift + slide vs a traditional slider
A traditional slider moves against its track and seals. Lift + slide changes the movement first: the handle raises the panel clear of the seal, then lowers it back into place when closed.
LIFT + SLIDE
Lift first. Then slide.
- Operation
- A handle turn lifts the moving panel clear of its seal before it slides.
- Effort
- The raised panel moves easily, even when the glass is large.
- Sealing
- Closing the handle lowers the panel back into the perimeter seal.
- Wear
- The panel is not dragged against the seal while it moves.
TRADITIONAL SLIDER
Move against the track.
- Operation
- The panel rides directly along its track under friction.
- Effort
- More friction means more force is needed as the panel grows.
- Sealing
- The panel continues to move against its sliding seals.
- Wear
- Repeated movement keeps the track and seals in contact over time.
SUPERIOR BY DESIGN
Four details work as one system.
Innotech frames its Lift + Slide design around the structure, glazing, hardware, and choices that shape the finished opening.
- Made in Canada
- NFRC and NAFS tested
- 2, 3 or 4 panels
- Widths up to 21 feet and heights up to 10 feet
Hybrid frame
Deep hybrid frames pair galvanized steel reinforcement with unplasticized (uPVC) profiles. Fusion-welded sash corners, a multi-chamber design, and triple weatherseals add strength and protection from air, water, and noise.
Advanced glazing
The frame is engineered to carry the weight of a high-performance insulated glass unit, with a wide glazing cavity, a stainless-steel warm-edge spacer, and thick panes with a choice of Low-E coating.
Innovative hardware
A turn of the large handle disengages the lock and lifts the door. With a gentle push, it slides open.
Flexible design
Choose 2, 3 or 4 panels in equal-width or off-centre configurations, double or triple glazing, and a frame finish and handle style suited to the project.
THE LARGE OPENING, THREE WAYS
Three ways to open a wall
Start with how you want to use the opening.
Compare the movement, the space each option asks from the room, and the kind of everyday use it supports.
Which to choose: Lift + Slide prioritizes the widest view, Easy Slide keeps the format simpler, and French doors suit familiar everyday hinged access.
NFRC tells you how efficiently the door holds heat. NAFS stress-tests what the whole opening can handle.
NFRC measures energy performance. NAFS evaluates the complete sliding door for air leakage, water penetration and structural load. Read both before deciding whether two doors truly perform alike.
Build the complete door. Put the complete door under pressure.
Sliding-door performance belongs to the assembled unit, not the glass alone. The system, panel arrangement, opening size, sill and hardware all travel with the NAFS class and grade.

Sliding-door anatomy
What's inside a Lift + Slide door.
The movement and the seal come from one complete assembly, from insulated glass and reinforced frame to lift hardware and perimeter sealing.
- Insulated glazingBoth models accept double or triple glazing, selected with the energy target and final configuration in mind.
- Steel-reinforced hybrid frameGalvanized steel reinforces the deep frame and supports the large sliding assembly.
- Lift hardwareThe handle raises the operable panel clear of its seal before the panel moves.
- Perimeter sealingReturning the handle lowers the panel back into the closed seal around the opening.
- Soft-close controlEvery Lift + Slide door includes soft-close hardware to manage the end of the panel's travel.
Opening capability
When the opening becomes part of the architecture.
The 88LS is the step-up model for the largest Lift + Slide openings.
This is an opening-width capability, not a structural test dimension. Panel arrangement, glass, handling and the wall assembly are resolved for each project.
PANEL LAYOUTS

FINISHES + GLASS
Colours and glass
Coordinate the frame with the room, the exterior, and the view. Use screen swatches to narrow the direction, then choose glass and grilles with the full elevation in mind.
A coordinated finish programme
Use these screen approximations to narrow the direction, then request a physical sample before making the final selection.

NAFS classes compared
Four NAFS classes. One letter is never the whole story.
Class describes the demands of the test program. Grade belongs to a particular system, panel arrangement and unit size, so the complete sliding-door configuration stays attached to the result.
| Class | Test-program position | Common fit | Lift + Slide results |
|---|---|---|---|
| AW Architectural | Most demanding class Lifecycle stress and repeat checks | Projects with increased loads, tighter deflection control and frequent or extreme use. | |
| CW Commercial | Commercial class Higher loading and heavier use | Larger openings and harder-working low- or mid-rise applications. | 76LS · 88LSconfiguration-dependent results |
| LC Light commercial | Bridge class Above the residential program | Larger residential and lighter commercial openings. | 76LS · 88LSconfiguration-dependent results |
| R Residential | Residential class Entry point in the class hierarchy | Many one- and two-family dwelling applications. |
How to read the proof
Read the complete sliding door, not one headline.
- 01System
76LS, 88LS and Easy Slide are different assemblies.
- 02Panel arrangement
XO and OXXO layouts do not share one blanket result.
- 03Unit size
A larger opening can carry a different grade within the same model.
- 04Complete opening
Sill, glass, anchorage and installation belong in the final specification.

Reading a sliding-door rating
Four standards. Four different jobs.
Every mark answers a different question. Use the measurement behind it, then match that evidence to the exact model, glazing and panel arrangement being quoted.
What does a NAFS rating mean?
It evaluates the complete sliding door against air, water and structural demands in a defined configuration.
- Issued under
- The North American Fenestration Standard, which assigns a performance class and grade to the complete assembly.
- Look for
- System, panel arrangement, unit size and the complete class-and-grade designation.
For Lift + Slide doors, keep the panel code and opening dimensions beside the structural result.
Read the NAFS classesWhat does a U-factor tell you?
How quickly heat passes through the whole door, including frame and glass. Lower means less heat transfer.
- Issued under
- NFRC energy ratings for a defined door and glazing configuration.
- Look for
- Whether the value belongs to double or triple glazing and whether it matches the selected model.
What does ENERGY STAR mean?
A government-backed efficiency threshold, not a ranking of every door that clears it.
- Issued under
- The ENERGY STAR program and its current efficiency criteria.
- Look for
- The NFRC value and final configuration behind the mark.
What do building-program marks mean?
Net Zero, LEED and Built Green are whole-building targets or programs. The sliding-door package is one part of the envelope.
- Applied to
- The complete project, with requirements coordinated across design, materials and energy performance.
- Look for
- The project target and the door values the energy model or specification requires.

From quote to installed
How your project runs
Getting the opening level, square, dry, and ready for the panel weight is what makes the finished door move and seal as intended.
Consultation
Confirm opening goals, traffic, panel movement, furniture clearance, envelope targets, finish, glass, and whether plans or an existing opening govern the work.
Measure & configure
Verify rough opening, floor elevation, panel scheme, sill depth, drainage path, structure, glazing, hardware, and delivery access.
Manufacture
Freeze panel handing, sill, glass, finish, handles, hardware, and assembly details before the unit is built to order in British Columbia.
Install day
Confirm safe handling, protect the work zone, prepare the opening, set the sill and frame level and square, fasten to the approved schedule, and integrate water and air control layers.
Commission & care
Demonstrate lift, slide, lower, lock, and softclose operation; verify panel clearances, compression, drainage, and hardware adjustment; record the final configuration.
