Gealan S 9000 Base
The entry model of the Gealan S 9000 uPVC window, with a bevelled face that makes the frame look slimmer.
Gealan S 9000 Base
The Base is the simplest version of the Gealan S 9000 uPVC window profile: 120 mm frame depth, Uf 1.10 W/m²K, and a sash that slopes away outwards at 15°. That bevel is not decoration but a trick of the light — the shadow on the angled face makes the 119 mm sightline look narrower than it is. Of the S 9000 versions this is the least expensive, and technically it is the equal of the others.

How much does a Gealan S 9000 Base uPVC window cost?
What comparable projects cost typically £320 to £448 per unit, excl. UK VAT and import duties The spread is too wide for a single amount; this is the range they fell within. for a unit of 1,000 × 1,400 mm measured on 94 quotes from our own archive This is a guide price, not a quote and not a final price. The amount for your own sizes is in the made-to-measure quote, which you request through the configurator.
The price of an S 9000 Base window depends on four things: the overall size, the layout (fixed, tilt and turn, door), the glass and the colour. If there is an amount above this section, it is a guide price from our quote history — not a quote and not a final price; the configurator itself shows no amount. You put your window together, send it as a request, and the price for your sizes is in the offer — you'll hear from us within three working days. Prices in GBP, excl. UK VAT and import duties, which are payable on delivery. Hardware and any discount are in your made-to-measure offer. Delivery to the UK is quoted with your offer. We supply, we don't install, and we don't charge for installation.

You are looking at 120 mm frame depth — the distance from inside to outside — with a 74 mm outer frame and 119 mm of it visible from the inside. The two drawings below are not a stand-alone profile sketch but a joint: how two S 9000 Base sections connect to each other. A separate 1:1 section of the outer frame on its own, without a joint, is something we have not yet found for this profile — see the note with each drawing.
Horizontal section through the mullion that joins two S 9000 Base sections side by side. Left and right you see the same tilt and turn frame, rebated; the mullion itself is 152 mm wide. This is the drawing you need to read a window with more than one section — most of our photos show a coupled window like this.
Vertical section through the transom that joins two S 9000 Base sections one above the other — for example a tilt and turn window with a fixed top light. The transom itself is 142 mm high; the frame around it keeps the familiar 120 mm frame depth.

Uf 1.10 W/m²K is the heat loss through the profile, not through the whole window. How well the window insulates in the end also depends on the glass (Ug) and on the ratio between profile and glazed area; that combination is called Uw, and it comes out of the configurator, not out of this table. The 120 mm frame depth decides how far the window sits into the reveal — measure that before you order.
This is a schematic cross-section, built from the measured frame depth, frame width and sightline. The chamber layout, seals and reinforcement are not measured — they come from the supplier's technical drawing.
S 9000 Base compared with Haax and Slim
Same size, same specification. Only the profile differs.
| Specifications | Gealan S 9000 Base | Gealan S 9000 Haax | Gealan S 9000 Slim |
|---|---|---|---|
| Material | uPVC | uPVC | uPVC |
| Uf | 1.10 | 1.10 | 1.10 |
| Frame depth | 120 mm | 120 mm | 82.5 mm |
| Sightline | 119 mm | 119 mm | 119 mm |
| Maximum size | 3,200 × 3,200 mm | 3,200 × 3,200 mm | 3,200 × 3,200 mm |
| Why something else | Same frame depth, same Uf, but square-edged instead of bevelled. Choose it if the window should sit flat in the elevation. | Same system, 82.5 mm instead of 120 mm frame depth. Shallower in the reveal, the same sightline. |
Side by side, true to scale
The same scale for all three, so what looks deeper here is deeper.
Where does the S 9000 Base fit?
New build
Suitable. The 120 mm frame depth fits the usual Dutch cavity-wall details; check it against your own wall build-up.
Renovation
Suitable, provided the existing structural opening is within 3,200 × 3,200 mm.
Listed buildings and conservation areas
Talk to your local planning authority first. A bevelled uPVC face is rarely allowed on a listed building or in a conservation area; in that case look at timber, which we don't supply.
Standards and Building Regulations in the UK
In the Netherlands, quality assurance for windows and doors runs through KOMO. It is not a standard but a certification: an independent certification body assesses a manufacturer against a set of assessment guidelines — for uPVC windows and doors that is BRL 0703 — and then issues a product certificate. What is certified is not only the finished product but also the production and the manufacturer's own quality control. KOMO is a Dutch scheme, not a British one.
SKG is the Dutch rating for burglar resistance. SKG stars sit on the hardware, not on the frame. For new-build homes, Dutch building regulations require windows and doors that can be reached from outside to meet class 2 of NEN 5096 — in European terms RC2 to EN 1627. Note what that says: it is a requirement for the complete window or door, including the hardware and including the way it is fixed. A window tested as RC2 but fitted wrongly is no longer an RC2 window. These are Dutch and European classifications; we make no claim about British security standards.
The fitting itself matters as much as the window. The Dutch fitting guidelines for uPVC windows and doors (VKG) come down to what good practice asks anywhere: the opening must allow an airtight, watertight, flat and square joint, and the loads on the window must be carried through fixings into the structure. We supply, we don't install, so this part is your installer's work.
In England, Approved Document L sets the limit for replacement windows in an existing home at a U-value of 1.4 W/m²K or WER band B; for doors it is 1.4 W/m²K or DSER band C (more than 60% glazed) or DSER band D (other doors), and a replacement may not perform worse than what it replaces. That U-value is for the whole window (Uw). The Uf on this page is the frame profile alone, so on its own it doesn't tell you whether a window complies; the Uw of your window is stated in your offer. Replacing windows is notifiable building work in England and Wales: an installer registered with a competent person scheme, such as FENSA or Certass, notifies it, or you notify building control before work starts. Because we don't install, that sits with your installer. Scotland and Northern Ireland have their own rules. We don't give Building Regulations advice — check with your installer or building control.
What we do not claim here: that our windows carry KOMO or SKG, or any British rating such as a Window Energy Rating. Those marks belong to the manufacturer and its production line, and we have not yet requested the details from our suppliers. Once we have them, they will be listed here with number and expiry date. Until then we only say what the marks are, not that we have them.

Gealan S 9000 Base: frequently asked questions
Can you deliver this profile to me in the UK?
We are a Dutch supplier and deliver to the Netherlands, Belgium, Germany and France. Delivery to the UK is quoted with your offer. Production time for the Gealan S 9000 Base is 6 to 8 weeks. You enter your postcode with your quote request. The route always ends at the quote request: not a guessed price, but a quote for your sizes.
What sizes can I order?
This profile goes up to 3,200 mm wide and 3,200 mm high. The widest opening part is 1,400 mm. At the small end: the narrowest section that can be made is 200 mm, the narrowest door section 600 mm, the narrowest side panel next to a door 180 mm, and a door section is no taller than 2,500 mm. That limit comes from Gealan's size table and applies to every colour; in white the system allows more, but we keep to the size that always holds. If you are close to the limit, ask us.
What is the lead time?
Production time is 6 to 8 weeks, the same for all our suppliers (our figure as of 15 September 2026). Delivery to the UK is quoted with your offer. The quote itself is quicker: you'll hear from us within three working days of your request; if it takes longer, you'll hear that within the same three working days, with the date it will be ready.
What exactly will arrive?
What you put together in the configurator is what arrives: the profile you chose, in your size and layout, with the glass and colour you picked. The summary — the last step before your request goes out — lists line by line what your configuration contains, and anything not listed there doesn't come with it. So you know before you unpack, not after. How and where it is delivered in the UK is set out in your offer.
Do you install it as well?
No. We supply, we don't install. That has one consequence you need to know: in England and Wales, replacing windows is **notifiable building work** under the Building Regulations. An installer registered with a competent person scheme, such as FENSA or Certass, notifies it; otherwise you notify building control before work starts. What we don't do is give Building Regulations advice — check with your installer or building control what applies in your situation.
Which glass and colours can I choose?
We offer six types of glass: HR++ double glazing (Ug 1.1), triple glazing (Ug 0.6), satin obscure glass in double and triple, and laminated safety glass class P4A in double (Ug 1.0) and triple (Ug 0.6). For colour there are through-coloured uPVC, dark and other foils for uPVC, and smooth or textured powder coating in a RAL colour for aluminium. Which combination is available on this profile is shown by the configurator — it refuses a combination that doesn't exist rather than quietly supplying it.
Can I send it back if I don't like it?
No. A window made to your measurements is made to order, and made-to-order goods fall outside the right to cancel. We say so before you order, not in the small print. In return, we take the risk out at the start: a size guarantee, a sample pack so you can see the colour in your own light, and a fixed procedure if anything is broken on delivery.
What if something is damaged on delivery?
Check it with the driver before you sign, and have any damage noted on the delivery note. Until the window is in your hands, damage in transit is **our risk**, not yours — we ship on DAP terms, so the risk stays with us until delivery. If you still find visible damage when you unpack, report it with photos **within two working days of delivery**. What you can't see on delivery isn't covered by that: for hidden defects your statutory rights apply unchanged.
