Drilling holes in your window frames? You’d rather not. Not in a rental property where it’s not allowed, not in listed buildings where it’s simply prohibited, and not in uPVC frames where it can cause cracks, leaks, and void your warranty.
Fortunately, you don’t have to. In this guide, we compare all the ways to install sun shading without drilling and help you choose the best method for your situation.

Rental property: landlords often don’t allow drilling into window frames. Suction cup sun shading is fully removable and leaves no marks, so you avoid extra costs when moving out.
uPVC frames: drilling into plastic (PVC) frames is risky. It can cause cracks and leaks, immediately voiding your warranty.
Listed buildings: with protected heritage properties, you’re not allowed to alter the facade. Suction cup sun shading is mounted on the glass, not on the frame or facade.
French doors: with traditional screens, you often can’t open the door when the screen is down. Suction cup sun shading is attached directly to the glass and moves with the door.
Flexibility: in autumn, you simply remove the screens and store them in the included box. In spring, you reinstall them. This way, they last for years.
There are several ways to install sun shading without drilling. Not every method is equally effective or suitable for every situation.
| Suction cups (on glass) | Velcro | Clamps | |
|---|---|---|---|
| How does it work? | Vacuum suction cup directly on the glass | Adhesive strip on the frame | Clamp grips onto the frame |
| Adheres to glass? | Yes | No (frame) | No (frame) |
| Drilling required? | No | No | No |
| Leaves marks after removal? | None | Adhesive residue on frame | Possible scratches |
| Withstands strong wind? | Yes (vacuum system + extra suction cup per running meter) | May come loose in strong wind | Moderate |
| Suitable for rental homes? | Yes | Not ideal (adhesive residue) | Not ideal (risk of scratches) |
| Suitable for uPVC frames? | Yes (attaches to glass, not the frame) | No (can damage PVC) | No (clamps onto PVC) |
| Non-standard window shapes? | Yes (triangle, trapezoid, semi-circular) | No | No |
| Reusable? | Yes, for years | No, single-use | Yes |
| Price | 10–15x cheaper than electric screens | From €5 (excluding screen) | From €10 (excluding screen) |
Suction cups are the only method that attaches directly to the glass, keeping your window frames completely undamaged. Sun Eclipse’s vacuum suction cups are firmly tightened onto the glass, ensuring a secure and reliable fit.
An additional suction cup is added per running meter, providing extra support. This makes them the ideal choice for rental properties, uPVC frames, and listed buildings.
uPVC window frames are sensitive to damage and have angled edges. As a result, suction cups, clamps, and Velcro don’t adhere well to the frame itself. The safest option is sun shading that attaches directly to the glass, not the frame.
The glass surface is completely flat, providing much better adhesion than uPVC frames. If the frame is less than 2 cm deep (which is common for uPVC), the screen is automatically made 1.5 cm larger on each side. This prevents light from leaking in around the edges.
As a tenant, you want to leave your home in its original condition when you move out. That means: no drill holes, no glue residue, and no damaged window frames. Suction cup sun shading is fully removable. You can take the screen off the window in just a few minutes, leaving no traces behind. Plus, you can easily take it with you to your next home.
For a student room, this is especially useful: rooms are often small, poorly ventilated, and frequently south-facing. In rental properties, drilling is usually not allowed, and buying an expensive air conditioner isn’t a realistic option for most students. With a Sun Eclipse screen, you can instantly make your room much cooler — and it’s 10 to 15 times cheaper than an electric screen.
With no-drill sun shading, you can choose between installing it on the inside or the outside of the window. The suction cups work effectively in both positions.
| Outdoor installation | Indoor installation | |
|---|---|---|
| Heat reduction | Most effective: heat doesn’t reach the glass | Less effective, but still a noticeable difference |
| How does it work? | The screen releases heat outside before it reaches the glass | The screen blocks sunlight |
| Easy to access? | Ground floor: yes. Higher floors: more difficult | Always easy to access |
| Best screen color | Dark (Anthracite, Black, Concrete) for best heat reduction and visibility | Light (White, Boulder) to maximize heat reflection |
| Ideal for | All accessible windows, living rooms | Apartments, skylights, hard-to-reach windows |
Our recommendation: choose outdoor installation where possible, and indoor installation where the outside is difficult to access. In both cases, you attach the screen using the same vacuum suction cups — without drilling.
Traditional electric screens can easily cost hundreds of euros per window, excluding installation. On top of that, you pay for a professional to measure and install them.
Suction cup sun shading is 10 to 15 times cheaper. You save not only on the product itself, but also on installation and measuring costs — because you do everything yourself.
Sun Eclipse is the most affordable provider on the market, the originator of this concept, and the only one offering custom solutions for non-standard window shapes. Delivery takes just 3 to 5 business days — no long process of quotes, measurements, and waiting.

Yes, the vacuum suction cups are attached directly to the glass. They are tightened onto the surface to create a strong vacuum, ensuring a firm and secure hold.
They are also fully removable and leave no marks behind.
Absolutely. Suction cups are ideal for uPVC frames. They attach to the glass, not the frame itself. Due to the angled edges of uPVC frames, other mounting methods often don’t adhere well. On glass, adhesion is optimal.
The vacuum suction cups are designed to withstand storm conditions. They are tightened onto the glass, creating an extra strong and secure hold.
An additional suction cup is added per running meter for extra support. Because the screens are mounted close to the window, they catch very little wind.
