Modern garage doors: flush, grooved and full-view glass

Flush, grooved, wood-look and all-glass doors, and what each one does through a Canadian winter, from Garaga's and Amarr's own specifications.

A modern garage door has a flat or lightly grooved face rather than raised panels or overlays. Three kinds cover most of them: a flush door, a grooved or wood-look plank door, and a full-view door of aluminium and glass.

The first two can be insulated steel up to R-16. The glass door cannot, and that is the choice to make first.

Protech Garage Doors sells, installs and repairs all three. The range we fit is on garage doors in Ottawa, with garage doors in Mississauga and garage doors in London for the other two branches. The figures below come from Garaga's and Amarr's own specification pages and brochures.

What makes a garage door modern

Garaga sorts its whole residential range into three styles: Traditional, Carriage House and Contemporary. Its residential page says Contemporary, also called Modern, doors have flat or lightly grooved surfaces, to match a house with square lines and large windows.

Its Modern Garage Doors collection has eight designs:

Flush: a flat face.
Grooved, 2 Grooves and 4 Grooves: a flat face cut with grooves.
Moderno 2 Beads and Moderno Multi.
Plank: wide, varied wood-look boards in printed finishes.
Vogue: Garaga's own design, which it calls exclusive.

The full-view door sits in a collection of its own, the California All-Glass door, and Garaga's new-styles page pairs it with Scandinavian and Japandi houses.

Amarr's modern doors are the Vista, a full-view door, and the EOS, a smooth flush door of 1 3/4 inches of polyurethane at R-13.5 in black or white. Amarr sells the EOS only in listed markets, and its May 2025 list names Abbotsford as the one Canadian location. In Ontario, confirm an EOS can be ordered before planning around one.

Flush and grooved steel doors

A flush or grooved door is built like any other steel door, so the insulation is a separate choice from the look. Garaga's construction page offers four builds behind the same faces:

Standard+: 1 3/4 inches, two steel skins with injected polyurethane, R-16.
Acadia 138: 1 3/8 inches, polyurethane, R-12.
OBI 2025: 2 inches, one steel skin with polystyrene, R-7.2.
OB 2025: one steel skin, not insulated.

There is an aluminium version too. Garaga's H-Tech is 1 3/4 inches of polyurethane in aluminium, rated R-16, and comes in Flush, 2 Grooves and 4 Grooves layouts.

Full-view aluminium and glass doors

A full-view door is a frame of aluminium extrusions holding glass across the whole face. On the California, rigid PVC mouldings hold each pane. It is 1 3/4 inches thick and is built 8 to 18 feet wide and 6 feet 6 inches to 8 feet high, in 1-inch steps.

Garaga offers more than 20 glass and glazing options for it, single-pane, insulated or tempered. Amarr's Vista lists 11 glass designs in single-pane, insulated and laminated glass, plus polycarbonate and acrylic panels, and WaterLok seals at the joints and around the glazing.

Why a glass door behaves differently in winter

A full-view door gives up insulation for light, and both makers' documents show it. Garaga's construction table puts the California in the non-insulated column. Its only insulation option is in the glass. Neither maker's page for its full-view door gives an R-value.

The glass figures make the gap plain. Garaga's LOW-E Argon page rates a sealed unit of two clear panes at R 2.0. With one Low-E pane and argon gas between them it rates R 3.6. The best of the two is under a quarter of the R-16 in a Standard+ section.

The frame matters too. Garaga's guide to all-glass doors calls aluminium a great thermal conductor, so the frame brings the outside cold to the inside face. In Ottawa that is not an occasional night. Environment Canada's 1991 to 2020 normals for the airport count 67.6 nights a year below minus 10 °C, and 15.6 below minus 20 °C, 8.1 of them in January.

Condensation on the glass

Large glass is the coldest surface in the room, so it fogs first when warm, damp air reaches it. Garaga's guide compares a full-view door with a patio door here, and its advice is the same: vent the dryer, the stove and the shower outside, and keep the room's humidity down.

Fog between the two panes of a sealed unit is a different fault. Garaga's January 2026 warranty covers its sealed glass units for 10 years against condensation forming inside them and 1 year for the thermal break, when Garaga or an authorized distributor installs them. A broken unit is not covered once the job is accepted.

Where a glass door fits

So a full-view door suits a detached or unheated garage, a workshop you heat only while you use it, or a room where you accept a cooler wall for the light. Over a heated garage with a bedroom above, an insulated flush or grooved door gives the same clean face at R-16. Insulated garage doors works through how much insulation a garage needs.

How to choose glass for a full-view door

Three questions settle the glass: how much privacy, how much safety, and how much heat you want to keep.

Privacy first. Garaga rates its glass from 0 to 5 for privacy. Clear glass shows the whole garage to the street, and more so at night with the light on. Sandblasted glass turns the door into a lit panel after dark instead. The California is offered in:

Clear: the most light and the least privacy.
White Sandblasted: frosted glass that lets the light through and hides the inside.
Black Satin: a black mirror effect that turns dark grey when lit from behind.
Grey, Mirrorpane, and four tints: Tinted, Dark Tinted, Bronze Tinted and Green Tinted.
Niagara, Diamond and Screen.

Amarr's Vista names its own set: Clear, Obscure, Frost, Snow, WhiteOut, Black Ice, Grey Lite and three tints, plus its ThermaPro Low-E glass.

Safety second. Tempered glass is heated and cooled until it is four to five times stronger than ordinary glass, and it breaks into small dull pieces. A sealed unit can be tempered on the inside pane only or on both. For an all-glass door, Garaga suggests both, which matters on a driveway where children play hockey.

Heat third. Low-E with argon costs almost no light: Garaga's figures give 79% of the light through, against 81% for two clear panes, for nearly twice the R-value.

Colours and finishes that suit a modern door

Garaga's modern doors come in more than 20 colours and wood tones, and the two it names first are Black and Iron Ore. Its new styles page calls Iron Ore the solid colour trendier than black: a warm grey with softer contrast, which it pairs with warm whites, beiges, blond wood and red-tinted brick.

For a wood look without the upkeep, the steel doors take printed finishes:

Natural Oak HD, offered across many designs, and Dark Walnut.
Cedar HD, Dark Acacia HD and Carbon Oak HD, exclusive to the Plank design.

The California frame comes in black, white or anodized as standard. Its semi-custom colours, from Iron Ore to Positive Red, are a liquid acrylic paint rather than the standard finish. Repainting any door yourself changes what the warranty covers, and garage door brands sets out how for each maker.

Modern doors Protech has fitted

The job photographs on Protech's own Business Profiles show each of these looks. One is a black full-view door with tinted glass under a grey stucco bay, beside a black front door with frosted inserts. Another is a pair of dark grey raised-panel doors replaced with two full-view doors in black aluminium frames, next to a front door with long glass inserts.

Others are grooved: black doors with horizontal grooves and a column of frosted or narrow windows at one edge, replacing white, beige or slate grey raised-panel doors. One more swaps a black raised-panel double door for a grey flat-faced door with a row of frosted windows.

Two of them, the full-view door under the stucco bay and a pair of black grooved doors, are among Protech's own photographs on the garage doors page.

How to choose a modern garage door, step by step

Settle what the garage is for. Heated, attached or under a bedroom points to an insulated flush or grooved door. Detached, unheated or a room you want filled with light can take a full-view door.
Measure the opening, not the door that hangs in it. Standard garage door sizes covers the clearances.
Choose the face: flush, grooved, plank or all-glass.
On a glass door, choose the privacy level, ask for tempered glass on both panes, and decide on Low-E with argon.
Choose the colour, then try the whole door on a photo of your house in Garaga's Build Your Door designer.

Then see it in person. In Ottawa, the showroom at 46 Grenfell Crescent, Unit A, in Nepean is open Monday to Friday from 8 to 6 and Saturday from 9 to 2. The opening is measured before anything is ordered, for garage door installation in Ottawa or at the other two branches.

Questions people ask

Short answers to what comes up most often.

What is the new trend in garage doors?

On Garaga's own new-styles page, it is wood-look planks and warm greys: the Plank design in Cedar, Dark Acacia and Carbon Oak printed finishes, Natural Oak HD across many designs, and Iron Ore, which Garaga calls trendier than black. Full-view glass doors sit on the same page.

Are glass garage doors insulated?

Not like a steel door. The frame is aluminium and the insulation comes only from the glass. Garaga rates its best sealed unit, Low-E with argon, at R 3.6, against R-16 for its Standard+ steel door, and publishes no R-value for the full-view door itself.

Are garage doors aluminium?

Most residential doors are steel. Aluminium is used for full-view frames, such as Garaga's California and Amarr's Vista, and for Garaga's H-Tech, an aluminium door with polyurethane inside rated R-16.

How thick is garage door glass?

In Garaga's sealed windows for its 1 3/4 and 1 3/8-inch doors, each pane is 3 mm, with a 1/2-inch air space, for a unit 3/4 of an inch thick. The California full-view door itself is 1 3/4 inches thick.

What is the most popular colour for a garage door?

No maker publishes a ranking. On its modern doors Garaga names Black and Iron Ore first.

What is a sandwich garage door?

A door with insulation held between two skins. Garaga's 3-layer doors are two steel skins with polyurethane injected between them, at R-12 or R-16. A 2-layer door has one skin with polystyrene and a backing.
