What Is a Facade Surround (Söve)?
Definition of the surround, its exterior and window use, types, the advantages of polyurethane, installation and the factors that determine its price — a comprehensive guide from a surround manufacturer.
A surround (Turkish: söve) is a decorative architectural profile applied around facade openings such as doors and windows, framing the structure. It both adds an aesthetic look to the facade and protects the window and door edges from external factors such as rain, wind and sun. Today the most preferred option is polyurethane surround — lightweight, waterproof and easy to install — although EPS (styrofoam), plaster and stone surrounds are also available.
What Does a Surround Do?
A surround serves both a functional and an aesthetic purpose:
1. Aesthetic frame: It emphasises windows and doors, adding depth and movement to the facade and giving the building character.
2. Protection: It protects the window edge from external factors; the sill (bottom surround) directs rainwater away from the facade, preventing the wall from getting dirty and damp.
3. Proportion and order: By organising the openings on the facade, it balances the architectural proportion of the building.
With these features, a surround is an indispensable decorative architectural element in both new buildings and facade renovation projects.

What Are the Types of Surround?
Surrounds vary by location of use, shape and material:
- Window surround: The most common type, wrapping around the window.
- Door surround: Frames entrance and interior doors to create emphasis.
- Sill (bottom surround): The sloped profile placed under the window that directs water away.
- Arched surround: Produced for arched and curved openings.
- Keystones and corner elements: Complementary details used together with the surround.
By material, surrounds are divided into polyurethane, EPS, plaster and stone. On facades, polyurethane and EPS are most common; indoors, polyurethane and plaster are preferred.
Why Is Polyurethane Surround Preferred?
Polyurethane surround is the most preferred material both on facades and indoors:
- Lightweight: Easy to transport and install, it does not load the facade.
- Waterproof, rot-proof: Resistant to moisture and frost; long-lasting on facades.
- Paintable: Can be painted any colour with facade paint.
- Ready-sized: Produced in standard profiles at the factory and simply cut and bonded on site.
- Detailed: Because it is moulded, fine ornamentation and sharp lines are preserved.
Compared to plaster it is far more resistant to breakage and moisture, and compared to EPS it is superior in impact resistance and detail sharpness.

How Is a Surround Installed?
Polyurethane surround is installed in simple steps:
1. Surface preparation: The application surface is cleaned of dust, grease and loose paint.
2. Measuring and cutting: The surround profile is marked to the window/door size; corners are cut at a 45° mitre.
3. Bonding: A polyurethane-based mounting adhesive is applied to the back of the surround and pressed onto the surface.
4. Mechanical support: For large profiles, additional support is provided with screws/dowels.
5. Joints and filling: Joints and corners are filled with filler and sanded.
6. Painting: The surface is painted with facade paint to complete the application.
The right adhesive and a clean mitre cut ensure a long-lasting installation.

What Determines Surround Prices?
A surround price cannot be expressed as a single figure; it depends on several factors:
- Profile size: As the width and height of the surround increase, the price per linear metre rises.
- Model complexity: Plain profiles are economical, while ornamented and arched models cost more.
- Material: Polyurethane, EPS and plaster fall into different price ranges.
- Quantity: The total length varies according to the project.

Frequently Asked Questions About Surrounds
What is a surround in short?
A surround is a decorative architectural profile applied around doors and windows, framing the structure. It adds aesthetics to the facade while protecting the window edge from external factors.
What is a surround used for on facades?
On facades, a surround is used to emphasise windows and doors, add depth to the facade, and — with the sill (bottom surround) — direct rainwater away from the wall.
Is polyurethane or plaster surround better?
On facades, polyurethane surround is better; it is waterproof, frost-proof and lightweight. Plaster surround is moisture-sensitive and brittle, so it is generally preferred indoors.
How is a surround installed?
The surface is cleaned, the surround is cut to size with a mitre, polyurethane mounting adhesive is applied to its back and it is pressed onto the surface; large profiles are supported with screws, then joints are filled and painted.
Can polyurethane surround be painted?
Yes. Polyurethane surround can be painted any colour with facade or interior paint. It is recommended to paint after installation and joint filling.
Is surround resistant to water and sun?
Polyurethane surround is waterproof, rot-proof and frost-resistant. When painted with suitable facade paint, it delivers long-lasting performance against UV and weather conditions.
How is the window surround size determined?
The window surround size is determined by the width and height of the window opening. The surround width is chosen according to the facade proportion; exact dimensions are planned per project.
What do surround prices depend on?
The surround price depends on the profile size, model complexity, material and total quantity. Because products are made to order, the price is given on a project basis.
