Slate or acrylic house number

Updated: 22 October 2026

You are choosing the face of the house number, not the whole comparison. A 1930s semi and a new rendered wall do not want the same surface, and neither slate nor acrylic has a weathering test in this set. This page holds that fork: what each face is, how heavy it is, how the characters are made, and which front it suits. There is no single winner. The twelve-row table is the [house number comparison](/hub/garden-decor/house-number). Shops that say both materials last ten to twenty years are talking about their own stock. That lifespan is not adopted for these ASINs.

What each face is in this set

The slate listing is one row. EDSG, B0875QF9G1, is £13.99, natural slate, UV printed, 4–6 mm thick, 410 g, with the title saying it is hand finished in the United Kingdom. UK reviews describe an earthy texture. One buyer wanted it for a 1930s semi rather than a glossy modern board. It is 4.6 from 4,008 reviews. The black glass-effect plaque, B06ZZGMWJM, is £7.99, acrylic and alloy steel, 240 g, 4.8 from 8,594 reviews. The clear Perspex plaque, B016OW4O0E, is £7.99 and 100 g. The floating Exalted board, B08LVTFS7N, is £7.99, and reviews describe a thin skin over a plastic core. Adhesive digits stay out of this fork.

Weight, thickness, and the size conflict

The slate is the heavy board, at 410 g, against 100 g for the Perspex plaque and 240 g for the glass-effect plaque. A 4–6 mm slate is a different fixing from a 15 mm acrylic sandwich. The EDSG title says 20 by 15 cm. The item-dimensions line says 30 cm by 20 cm. Measure what arrives. Outdoor and weatherproof questions are unanswered. Which front should buy which row is on the best house number plaque page.

Which front it suits

Choose slate when the front should read as stone, as in the 1930s semi in the EDSG reviews. You pay £13.99 and you accept a size line that contradicts itself. Choose a glass-effect board when the front is modern and £7.99 is the budget. Choose the laser-cut mirror face when you want the 300 mm cut-out. The film belongs on the how to fit a house number page. If you have not yet separated the job from the material, start with the house number buying guide.

Common questions

Which listing in this set is the slate plaque?
EDSG, B0875QF9G1, at £13.99 with 4.6 from 4,008 reviews. The title says natural slate, UV printed, hand finished in the UK, in a 20 by 15 cm rectangle. Thickness is 4–6 mm and the weight is 410 g. It is the only slate row. The other faces are acrylic, Perspex, composite, or two-part aluminium.
Is slate thicker or heavier here than the acrylic plaques?
It is heavier, at 410 g, than the 100 g Perspex and composite boards and the 240 g glass-effect plaque. It is not thicker in the way the 15 mm acrylic sandwich is. The slate line is 4–6 mm. The glass-effect and Perspex plaques are listed at 15 mm deep. Weight and thickness are answering different questions, and neither is a weathering result.
Do acrylic letters stay white?
Not in every review in this set. The black glass-effect sample includes print that looked blue-grey rather than bright white. The floating composite sample includes pale grey or blue lettering. The Perspex sample includes lettering that started peeling after about 5.5 years, beside a 10-year Perspex claim on the listing. The white in the photograph is not a guarantee.
What does composite aluminium mean on the Exalted board?
The spec table says aluminium. A UK review of B08LVTFS7N describes a thin aluminium skin, about 0.5 mm either side of a plastic core, and dips over the holes. Treat composite as that sandwich, not as a solid plate. The Paramount at £8.99 is the two-part aluminium sign, and it has its own complaints about print and about grey that looked purple.
Is a laser-cut mirror back the same material as a printed acrylic face?
Both are acrylic in the spec tables, and they are not the same face. The Bellisima rows are laser-cut, 300 mm by 160 mm, with a copper mirror at £14.99 or a silver mirror at £16.99, sharing 4.5 from 1,472 reviews. The £7.99 boards are printed glass-effect, Perspex, or composite faces. Cut-out lettering can still sit on a backing that reviews found too dark to read.
Will slate or acrylic fade?
This set cannot say either will not fade. No weathering test was run. A slate buyer hoped the print would survive winter, which is not a failure and not a pass. Acrylic reviews include peel, blue-grey print, and an expectation of fade on the composite. Shop claims of ten to twenty years are those shops' claims.
