If there’s an architect on the project, the glass door spec usually goes through them. That’s the right path. Done well, the architect handles the spec language, the homeowner gets a coherent design, and the supplier delivers what was specified. Done badly, the spec is too vague, the supplier interprets in ways the architect didn’t intend, and the homeowner finds out about the gap on install day.
Here’s how the collaboration should run on a Jamaican custom build or major renovation.
When the spec actually gets done
The right window for finalising glass door specs is the second half of the Design Development phase. The building plans are settled, but construction documents haven’t gone out yet. By that point the architect knows where every opening goes, what surrounding finishes exist, and what the structural framing supports.
Spec too early and the design keeps moving under you. Spec too late and the construction documents go out without door details, leaving the supplier to make decisions the architect should have made.
On a Jamaican custom build, this usually puts the glass door spec conversation 2 to 4 months before construction starts. On a major renovation, it’s a few weeks before demolition.
What the architect specifies
The architect’s job is to specify the design intent in a way the supplier can quote and fabricate without ambiguity. The spec should cover:
The door type and configuration. Sliding patio, hinged french, pivot, frameless shower, etc. Panel count, swing direction, which panels are operable and which are fixed.
The opening dimensions. Width, height, head height above finished floor.
Frame material and finish. Aluminum profile family, finish colour, thermal break or no.
Glass spec. Tempered single pane, insulated unit, Low-E coating, laminated, frosted, reeded.
Hardware. Handle style, lock type, hinges, closers. Often specified by brand and model on premium projects, by category on value projects.
Performance requirements. Hurricane rating, acoustic rating, fire rating if applicable.
What the architect doesn’t usually need to specify: install methodology (that’s the supplier’s domain) and every fastener (that’s in the manufacturer’s installation manual). But the spec should be detailed enough that two different suppliers quoting it would deliver functionally equivalent doors.
What gets unclear in practice
A few patterns where the architect’s spec leaves room for misinterpretation:
Finish colour drift. “Black aluminum” can mean RAL 9005 matte, RAL 9011 gloss, or any of half a dozen other blacks. Different suppliers stock different blacks. Unless the spec names a specific RAL or BS colour, the delivered colour is partly luck.
Spec category vs spec product. “Low-E coated glass” is a category. “Guardian SunGuard SNX 51/23” is a product. Categories let suppliers substitute; product callouts force them to deliver that specific glass.
Hardware “or equivalent”. “Mortise lock by Schlage or equivalent” gives the supplier permission to substitute. “Schlage L9080” doesn’t. The architect should be intentional about which.
Performance ratings without test references. “Hurricane-rated” without specifying ASTM E1886/E1996 or Miami-Dade NOA. Different suppliers interpret “hurricane-rated” differently.
Missing details. Sealants, weatherstripping spec, threshold details, drainage paths. Easy to skip in the architect’s spec, but they’re where leaks come from.
The architect can leave some of these gaps deliberately (often the homeowner is making the final call on aesthetic items). The gaps should be intentional and labeled, not accidental.
The supplier’s submittal
After the architect’s spec goes out, the supplier responds with a submittal. That’s the supplier’s interpretation of the spec, with specific products, dimensions, and details called out for the architect to confirm before fabrication starts.
A good submittal includes shop drawings showing every glass door with dimensions and components, manufacturer technical data on the proposed products, certifications for performance ratings, and any deviations from the architect’s spec called out explicitly.
The architect reviews and either approves, requests revisions, or rejects. This is the moment to catch mismatches between intent and proposed delivery. Two or three iteration rounds before approval is normal.
The common failure mode is the submittal getting waved through without careful review, then problems showing up on install. The architect’s review fee for submittals is small compared to the cost of correcting an install built from an under-reviewed submittal.
Where the homeowner fits in
The homeowner is the client, but the architect mediates most of the supplier conversation. The homeowner engages directly on:
Aesthetic decisions. Finish colour, hardware style, glass type (clear vs frosted, reeded vs flat). Taste decisions the architect presents but the homeowner picks.
Budget decisions. Premium spec vs value spec on each door. The architect lays out the options; the homeowner sets the price point.
Specific brand preferences. If the homeowner has a strong preference for a particular hardware brand or glass manufacturer, that gets into the spec via the homeowner-to-architect channel, not directly to the supplier.
Final approval. The homeowner signs off on the spec before construction documents go out, and again on the submittal before fabrication.
The homeowner doesn’t drive the technical spec language. That’s the architect’s role. Reviewing and asking questions is good; rewriting the spec around the architect is a recipe for confusion.
When the supplier should engage with the architect directly
For most projects, the supplier engages with the architect (or the GC) rather than the homeowner. The right times for direct supplier-architect contact:
Pre-spec consultation, where the supplier advises the architect on what’s actually buildable, what lead times are realistic, and which spec items would substantially affect cost.
Submittal review and revision cycles, where the architect’s questions get answered with technical data instead of relayed through the GC.
Pre-install coordination, where the supplier confirms the rough opening dimensions before fabrication and confirms the install schedule with the architect or GC.
Post-install walkthrough, where the architect signs off that the installed doors match the approved submittal.
Skipping any of these in favour of GC-mediated communication tends to introduce delays and miscommunications.
What to ask the supplier as the architect
A few specific questions worth putting to the supplier during the spec conversation:
What’s the lead time for the proposed spec, both fabrication and on-site install? Confirms the project schedule.
What deviations from typical residential spec are needed for the site’s specific exposure (coastal, hillside, hurricane zone)? Surfaces upgrades the architect should bake into the spec.
What’s the warranty structure on the proposed products, and what’s required to maintain it? Affects the final spec language and the homeowner’s after-care expectations.
What’s the install crew’s experience with this product line? Some product lines need crews trained on them specifically; mismatch causes install problems.
What documentation will the supplier provide for permit submission and inspection? Confirms the paperwork side, especially for commercial work or hurricane-rated installs.

Frequently asked questions
When during a custom build should glass door specs be finalised?
In the second half of the Design Development phase, after the building plans are settled but before construction documents are finalised. For Jamaican custom builds, that’s typically 2 to 4 months before construction starts. For major renovations, a few weeks before demolition. Earlier risks the design changing under the spec; later means construction documents go out without door details.
What should the architect’s glass door spec include?
Door type and configuration, opening dimensions, frame material and finish (with specific colour reference), glass spec (single pane vs insulated, Low-E, laminated, etc.), hardware spec (specific brands or categories with substitution permissions), and performance requirements (hurricane rating, acoustic rating, fire rating if applicable). Detailed enough that two suppliers quoting it would deliver equivalent doors.
What’s a submittal and why does it matter?
A submittal is the supplier’s interpretation of the architect’s spec, with specific products, dimensions, and details called out for architect approval before fabrication starts. It usually includes shop drawings, manufacturer technical data, performance certifications, and any spec deviations called out explicitly. Catching mismatches at submittal review is much cheaper than catching them on install.
When should the homeowner engage directly with the glass door supplier?
On aesthetic decisions (finish colour, hardware style, glass type), budget decisions (premium vs value spec), specific brand preferences, and final approval. Day-to-day technical conversation should go through the architect. Homeowners who try to rewrite the spec around the architect tend to create confusion that costs time and money to resolve.
What if the architect’s spec is unclear and the supplier interprets it differently than intended?
That’s what the submittal review process catches. The submittal is the supplier’s interpretation; the architect reviews and either approves or requests revisions. Two or three iterations before approval is normal. Skipping careful submittal review is the most common reason installed doors don’t match the architect’s actual intent.
The next step
If you’re an architect speccing glass doors for a Jamaican project, the contact page is the way to start a pre-spec conversation. We can flag spec items worth being explicit about for the site’s specific exposure and walk through the products we typically supply.
For projects ready to quote against a finalised spec, the quote request form takes the spec package and the drawings.
The glass doors service page covers what we install.
Architect-led glass door projects go best when the architect, homeowner, and supplier each play their actual role and the submittal review gets real attention. Done that way, install day is anticlimactic, which is the goal.
