Should I use poly or a smart membrane?

Most straightforward The Orchards At Ellerslie walls are fine with 6-mil poly, continuous and sealed. A variable-permeance membrane is worth it on retrofits and some basement details because it gives the assembly a drying path in both directions.

Does it matter where the sheets overlap?

Yes. A lap must land on solid framing and be sealed with acoustical sealant compressed between layers. An unsupported lap taped across a cavity flexes with pressure changes and works loose.

Can you install the barrier if someone else did the insulation?

Yes, but we check the insulation first. A barrier over a poorly filled cavity locks the problem in, and once the board is on neither can be corrected without opening the wall.

Does it matter where the sheet meets the ceiling and floor?

It is the whole job. Left loose at the top or bottom plate, warm air simply goes over or under a perfectly installed sheet. The junction into a vaulted ceiling is the most commonly skipped and the wettest point in the room.

Can I add poly over insulation that already has a facing?

Usually no. Two retarders leave any moisture that gets in with no direction to dry. We check what is already in the wall before adding to it rather than assuming the cavity is bare.

Will this stop water coming through my basement wall?

No, and installing it would hide the evidence. Water coming through a wall is a drainage and waterproofing problem. Vapour control manages moisture in the air, not liquid water, and we will say so rather than board over it.

Vapour barrier in The Orchards At Ellerslie, sealed as a continuous plane

A vapour barrier only works as a continuous plane. In The Orchards At Ellerslie the failures are almost never the sheet itself — they are the electrical boxes, the top and bottom plates, the window returns and the penetrations, where the poly is cut and not resealed.

Inspection, and leaving it visible

It gets checked before it is covered

Vapour barrier and air sealing in The Orchards At Ellerslie are inspected before drywall covers them. We sequence to your inspection date rather than boarding ahead and covering something the inspector needs to see.

If it does not pass

We want the inspector's note directly. Most failures are specific — an unsealed box, a floating seam, a torn return — and they are corrected faster from the actual note than from a second-hand summary.

Top plates, bottom plates and the perimeter

The edges do the leaking

The continuous joints at the top and bottom of an The Orchards At Ellerslie wall are longer than every box and lap put together, and they are the easiest to seal well or badly.

What good looks like

Sealant on the plate, poly laid into it and compressed by the framing or the board above, carried around corners rather than cut and butted at every change of direction.

Electrical boxes, the usual failure point

A hole in the plane

Every outlet and switch in an The Orchards At Ellerslie exterior wall is a cut in the poly. Left unsealed it is a direct path for moist air into the cavity, and the boxes are usually the coldest spot on the wall.

Poly hats and sealant

Boxes get a poly hat or an air-sealed box, and the poly is sealed to it rather than simply cut around. It is a small detail repeated dozens of times, which is exactly why it gets skipped.

Laps, and the framing member behind them

Where sheets meet

A lap needs to land on solid framing and be sealed with acoustical sealant compressed between the layers, not taped in mid-air across a cavity.

Why it fails otherwise

An unsupported lap flexes with pressure changes and the seal works loose. In an The Orchards At Ellerslie build the sheets are planned so that laps fall on studs rather than wherever the roll ran out.

Where the barrier meets the ceiling and the floor

The two continuous edges

A The Orchards At Ellerslie wall barrier has to be sealed at the top plate and the bottom plate. Left loose, warm air simply goes over or under a perfectly installed sheet.

Cathedral and vaulted areas

Where a wall runs into a vaulted ceiling the junction is awkward and often skipped. It is also the warmest, wettest point in the room because that is where the air collects. It gets detailed properly or the rest of the sheet is decorative.

Renovations, and meeting an existing barrier

Continuity across old and new

In an The Orchards At Ellerslie renovation the new poly has to tie into whatever is already in the wall. A new sheet stopped at the edge of the work leaves an open seam inside the assembly.

What we look for

Whether an existing barrier is present at all, what condition it is in, and whether there is a second one somewhere that would trap moisture between the two. Older renovations quite often have both, and finding that before boarding is worth the hour it takes.
