Benefits of installing windows with frame screws
Programa Plus frame screw – our best tips
Programa Plus reduces the risk of the frame cracking and allows installation without packers. What is more, you can adjust the frame afterwards without damaging it.

Advantages of the frame screw
Easy subsequent adjustment and removal without damage
With the frame screw you can install windows and doors without packers. The installation is therefore fully adjustable, and you can easily remove it at any time without damaging the frame or the substrate.
Lower risk of the frame cracking
The frame screw creates a clean entry hole thanks to four cutting grooves on the sleeve, which cut through the wood fibres as it is screwed in. This minimises the risk of the frame timber cracking when the frame screw is too close to the edge. You will not notice a cracked frame straight away, but only after several months, when the door starts to become hard to close.
Lower risk of stripping the sleeve
If you tighten the frame too much on one side without loosening it on the opposite side, there is a risk of stripping the sleeve. The perfectly round Programa Plus sleeve greatly reduces this risk. Thanks to the thicker sleeve wall, the risk of the sleeve cracking in an angled installation is also much lower.
Easier insulation around doors and windows
The frame screw improves and simplifies insulation – when installing with frame screws, you can fill the gap continuously with mineral wool or gun foam.
What you can install:
* front doors
* interior doors
* windows
* glazed walls
Which wall materials can you install into?
* wood
* concrete
* solid brick
* lightweight concrete
* hollow brick
* expanded clay aggregate concrete
Recommended for:
* frame renovation
* installing frames in old houses
* installing frames that are out of true

Frame installation – choose the right screw length
Frame screws come in different lengths, and it is important to choose the right one for your installation.
The length depends on the gap width and partly on the material you are fixing the frame into. The gap width is the space between the frame and the wall. The Programa frame screw comes in four lengths – so you can install the frame comfortably even when the gap varies in width on different sides of the window or door.
| Gap width | Screw length |
| 0 – 5 mm | 50 mm |
| 5 – 15 mm | 70 mm |
| 15 – 35 mm | 90 mm |
| 35 – 85 mm | 140 mm |


Installing a frame into concrete and brick?
If you are installing a window or door into concrete or brick, disregard the table above. The fixed recommended screw lengths in the list below apply. And remember: always use a plug!
- Installing into concrete with a plug: use a 90 mm screw
- Installing into lightweight concrete or hollow brick with a plug: use a 140 mm screw
Positioning the frame screws
For a compliant frame installation, install in accordance with Swedish standard SS 81 81 43:2020. Here are three principles from this standard that must be followed in every frame installation.
Frame height
If the window is taller than 1300 mm, there must be at least 3 fixing holes in each side jamb of the frame.
Frame width
If the window is wider than 1000 mm, frame screws are also fixed in the head and sill of the frame. If the frame has a centre mullion, the screw is fitted 100 mm from it.
Frame depth
Frames less than 130 mm deep have one row of fixing holes. Frames over 130 mm deep have two rows of fixing holes.
