OVER SILL ANTHRACITE 2.5m 170mm DEPTH

The Over Sill Anthracite 2.5m 170mm Depth carries a window sill out over the face of an insulated, rendered wall: one 2.5 m length of dark profile at 170 mm depth, the third of four. It carries a dark sill line across the opening, part of the oversill range, sold alongside the matching verge trim and end caps.

The Over Sill Anthracite 2.5m 170mm Depth Profile

The product image shows a flat sill board with a short upstand along its back edge and a front edge turned down, pictured with an end cap fitted at each end. The same picture stands on all four anthracite depths, so it shows the shape of the family rather than the 170 mm size. The listing gives three facts about the item:

• Length: one 2.5 m length.
• Depth: 170 mm, the third of four depths in anthracite and the second deepest.
• End caps: the title names the profile only, and the range sells the caps as their own item, the anthracite end cap pair, listed for the sill profiles and the verge trim of the same colour.

Four Depths in Anthracite

The same anthracite profile is listed in four depths, all on the 2.5 m length, and 170 mm is the third of them. The other three are:

• 110 mm: the 110 mm anthracite over sill, the shallowest of the four.
• 140 mm: the 140 mm anthracite over sill, one step shallower than this one.
• 220 mm: the 220 mm anthracite over sill, the deepest of the four.

The listing does not say what the depth is measured across, or which wall build-up each depth is made for. Where two depths both look possible, the deeper of the pair is not by default the safer pick; the build-up on site decides.

Settling the Depth Before You Order

No build-up is named for any of the four depths, so the depth is settled with the counter. Two measurements from site make that a short call:

• The new build-up: the thickness of insulation and render going onto the wall at the opening, measured on site rather than taken from the drawing.
• The existing sill: how far the current sill stands out from the wall face today.

Ring Renders World on 023 8200 2442 with both figures and settle the depth before the order goes in. Where the openings on one elevation differ, give the figures for each.

How Many Lengths and Caps an Opening Takes

Measure each sill and divide by the 2.5 m length, rounding up: a 1.2 m opening takes one length cut down, and a 4.1 m opening takes 4.1 ÷ 2.5 = 1.64, so two lengths. Then count open ends, not lengths:

• One opening, two open ends: one end cap pair, however many lengths the sill is made of.
• A bay of separate sills: each separate sill with two open ends takes its own pair.
• Openings wider than 2.5 m: the range lists no joint piece, so settle how two lengths meet with the counter before ordering.

The Dark Trim Family

The sill profiles belong to one colour family. In anthracite the range also holds:

• Verge trim: the anthracite verge trim with an upstand, for the top edge of the wall.
• End caps: the anthracite pair, listed for the sill profiles and the verge trim.

Each end cap pair is sold for the trim of its own colour, so a dark sill takes the dark pair.

Anthracite or White

The 170 mm depth is listed in two colours, and the colour of the scheme decides:

• Anthracite: this profile, with the anthracite verge trim and the anthracite end cap pair.
• White: the white 170 mm over sill, with the white verge trim and the white end cap pair.

Fitting the Over Sill

The listing gives no fixing method, sealant or sequence for the profile. Two guides cover the work at the openings:

• The sill profiles: measuring, cutting and closing runs, in the guide on how to install window sill extensions.
• The openings: how sills, beads and render meet, in the guide to render detailing at door and window openings.

FAQ

Which insulation thickness does the 170 mm depth suit?

The listing names no build-up for any of the four depths. Ring 023 8200 2442 with the insulation and render thickness and the current sill projection before ordering.

Does the picture show the 170 mm profile?

It shows the family shape. The same image stands on the 110, 140, 170 and 220 mm anthracite listings, so the depth comes from the title, not from the picture.

Is the profile aluminium or uPVC?

The listing names no material, coating, colour code or thickness. Where the material matters to the specification, ask the counter before ordering.

Are end caps included?

The title names the profile only; the range sells the anthracite end cap pair as its own item. Order one pair for each sill with two open ends.

Is the 170 mm depth sold in white?

Yes, as the white 170 mm over sill, with its own white end cap pair.
