Window frames
Frames that combine comfort with character
High-quality Aluplast frames, precisely measured and expertly installed for lasting comfort.

- 42 mm triple glazing as standard
Triple glazing comes as standard on our new frames. Where it does not suit the opening, we look at whether HR++ works better.
- Low-maintenance and durable
uPVC frames never need painting. Cleaning is enough, and the colour stays stable for years.
- Tailored personal advice
We look at how each room uses its window, then match the profile, colour and glazing to it.
- Installed by our own team
No subcontractors: the people who measure are the people who fit, so one company stays responsible.
The benefits
Why choose uPVC frames?
uPVC frames insulate well, are easy to clean and remain neat for years without painting. With the right colour, texture and layout, they suit both modern and existing homes.
- Low-maintenance: no painting required
- Strong thermal and acoustic insulation
- Resistant to moisture and the elements
- Choice of colours, textures and window layouts
What you save
Where the savings come from
New frames pay you back in two ways: the maintenance that timber frames demand disappears, and you heat less because the glazing and profile hold the warmth inside.
Timber frames need repainting outside every five to eight years, and sooner on the sunny or weather-facing side. Skip a round and rot follows, at which point repair costs a multiple of what painting would have. uPVC frames never need painting; water and a mild cleaner are enough. Across the life of a set of frames, that is several painting jobs you no longer schedule and no longer pay for.
The second saving is insulation. Single glazing and older double glazing let a lot of heat through, and with old frames more warmth escapes around the joints. With triple glazing in a well-insulated frame you notice the difference in the draught by the window, the noise from outside and how long the heating stays on. How much gas you save depends on your current glazing, the square metres of glass, the type of home and how you heat it; Milieu Centraal publishes current worked examples per property type. We would rather not quote a figure we cannot guarantee — but the quotation states exactly which insulation value you get.
- No repainting every five to eight years
- No rot, and therefore no repair costs
- Less heat lost through glazing and joints
- Less draught by the window and less outside noise
Our core system
Aluplast Ideal 7000 NL: German top quality
We frequently use Aluplast Ideal 7000 NL, a profile system of German top quality. It combines insulation, security and a neat finish. During the advice appointment, we determine the right configuration for every window or door opening.
- German profile system by Aluplast
- 120 mm installation depth
- 42 mm HR+++ glazing as standard at Soleca
- Closed steel reinforcement in the frame
Tailored finish
Colour, texture and window type
The appearance is determined by more than the profile alone. We match the colour, woodgrain, window layout and operation to your home and how you use each room.
On colour you are not limited to a short standard list: every RAL-certified colour is available. Cream, white and anthracite are chosen most often, but if you want the frames to match a specific colour on your home, that is possible.
- Every RAL-certified colour available
- Fixed windows, tilt-and-turn windows and doors
- Ventilation grilles and insect screens available
- Coordinated with the façade and front door
Glazing guide
Which glazing suits your home?
For new frames, HR++ and triple glazing are the relevant choices. We assess each room to determine what best suits your insulation goals, local noise and existing façade.
HR++ glazing
High-performance double glazing, often suitable where triple glazing is not technically necessary or possible.
42 mm HR+++ glazing
Three panes with two insulating cavities. This is Soleca's standard for new window frames.
Specialist glazing
Solar-control, acoustic or safety glass where the location or use of the room calls for it.
Pricing
What do new frames cost?
The price depends on the dimensions, window layout, glazing, colour and optional extras. A fixed window is usually more economical than a tilt-and-turn window with additional hardware.
After advice and measuring, you receive a transparent tailored quote clearly listing the selected frames, glazing, options and installation.
Front doors
A front door that matches the frame
New window frames deserve a front door that matches them in colour and detailing. We work with EkoLine door panels, available in a wide range of styles: from flat, modern panels to classic versions with glazed sections and decorative mouldings.
During the advice appointment we look together at which panel suits your home and how to match it to the colour of the frames. The brochure shows the full range, so you can take your time over it at home.

Flat and classic versions, with or without glazed sections and decorative mouldings.
Matched to your frames
We choose the colour and detailing so the door and frames read as one whole.
Measured to fit
The door is manufactured to the final dimensions of your specific situation.
Fitted by our own team
The same installers who fit your frames also hang the door.

Security
What we look at for burglary resistance
With uPVC frames, quality and security go together. That is why we fit SKG**-rated locking hardware as standard. If you want the highest level of security available, you can choose SKG*** for a small additional cost.
Which measures make sense in your situation depends on where the frame is: a first-floor window at the back calls for something different from a front door on the street. During the advice appointment we go through this opening by opening.
SKG** as standard
Every frame is fitted with SKG**-rated locking hardware as standard.
SKG*** as an option
For a small additional cost you move up to SKG***, the highest class available.
Reinforced profile
Closed steel as standard in the frame makes it stiffer and harder to force.
Assessed per opening
Accessible windows and doors get more attention than a roof window at height.

We had window frames installed by Soleca. We had pleasant contact with Mathis and then had the pleasure of welcoming Willem and Willem to our home for the installation. I would definitely recommend the guys!
Milan Breedveld
After searching for weeks for a company willing to install our window frames at a reasonable price, we finally ended up at Soleca. It was well worth the wait! I was skeptical due to previous experiences with contractors, but that proved unfounded. The window frames were installed very neatly and quickly. I recommend this company to everyone!
