The customer must compute the attic’s insolation and ascertain the necessary air exchange rate based on the room’s intended use before selecting the preferred translucent element model.

Features of measurement and calculation

In order to measure the window blocks for the Velux attic, the following adjustments must be made:

• The pitch between the rafters is measured “cleanly”, taking into account the movement of structures during operation by 1 – 3 mm.
• The lowest point of location of the horizontal impost of the attic window is determined – the height from the floor, the distance from the junction of the inclined part of the roof with the wall or floor of the attic.
• The required distance from the bottom of the future translucent structure to the top of the element installation is determined.
• The result obtained is recorded on paper.

After taking measurements, the following procedures must be followed in order to choose a window unit:

• A sketch of the window structure is drawn up based on the measurements taken.
• A window unit with identical or similar dimensions is selected from the catalog.
• The dimensions of the window are taken based on the mandatory organization of the installation gap between the profile and the rafters – 15 – 20 mm.

If the window frame’s modular size differs from the rafters’ pitch, the supporting structures may need to be rearranged, which compromises the integrity of the structure as a whole. In this sense, it is advised to first set the rafter pitch with the window unit installation in mind.

Installation Rules

The following prerequisites must be met in order to install Velux windows, according to a previously created technological map:

• The opening must be decorated around the entire perimeter, cleared of old structures.
• A vapor-permeable waterproofing membrane is tripled along the perimeter of the window block.
• At the corner points of the profiles, as well as along their length, in increments of 300 – 400 mm, anchor plates are mounted.
• The window is tried on between the rafters and orthogonal coverings.
• The structure is wedged in the body of the opening using plastic elements.
• The alignment of the window block and rafter legs is checked.
• If necessary, the position of the frame is adjusted with a rubber hammer.
• Anchor plates are fixed to the roof rafters.
• The wedges are removed from the gaps, which, in turn, are subject to filling with polyurethane foam.
• After the foam has polymerized, its remains are cut off with a knife, after which a vapor-permeable tape is glued to the inside of the seam,
• Insulation and other layers of the pie are laid on the outside of the roof, after which the finishing coating is applied with the design of the junction unit.

The best course of action would be to hire professionals to handle the installation and positioning of these window units due to their increased complexity. They will finish the job quickly and efficiently and will offer a long-term guarantee on the outcome.

Adjustment

Velux windows are user-friendly because sophisticated fixtures can be readily adjusted with a slotted or Phillips screwdriver in your hands:

• If the mid-pivot sash is skewed, at each of the points of its attachment to the fixed window frame there is an adjusting screw, when turned, the structural element moves in the longitudinal direction.
• By turning the adjacent screw at the attachment point, the user can slightly correct the misalignment of the mechanism.
• When the screw of the clamping pins rotates, the pressing force of the sash changes.
• If the window is blowing or leaking, it is necessary to change the position of the counter plates for the trunnions on the fixed frame by turning one of the two screws.

Because the screws are extremely sensitive, adjustments must be made by hand only after the mechanism has rotated 90 to 180 degrees. This allows for precise control over the sash’s opening and closing.

What slopes are suitable?

Regarding Velux roof window systems Slope framing elements of the following kinds are appropriate:

• For classic products located in a roofing pie, with a rafter slope of more than 35 degrees, it is recommended to arrange inclined slopes from 15 to 60 degrees, to allow morning sun exposure.
• If the thickness of the roof does not exceed the size of the window frame, it is better to make the slopes straight.
• In the living rooms of wooden houses, the best solution would be to install frames made of boards or lining, if such a style is consistent with the interior design.
• When decorating a room in a modern style, a frame made of plasterboard sheets with painting is allowed.
• For energy-efficient windows, it is recommended to ensure excellent thermal performance of the installation stacks by organizing slopes from sandwich panels.
• In bathrooms and other rooms with high temperature and humidity conditions, slopes should be made of waterproof materials – plastic linings or ceramic tiles.

The final slope framing is determined by the thermal requirements, temperature, humidity, and interior design style.

Possible problems and their repair

Every product supplied is covered by a multi-year warranty from the Velux manufacturer. Simultaneously, not a single roof window is protected against unintentional breaking:

• The sash is skewed – adjustment of the fittings is required with repeated control of the opening of the moving element.
• Leakage from under the movable sash – it may be necessary to clean the inner plane of the profile from ice, or replace the sealing tape around the perimeter of the junction.
• Leakage of a window block at the installation joint – it is necessary to remove the lining at the junction of the roofing pie and the window frame, and then seal the joint, with its preliminary cleaning and drying.
• Blowing from under the sash – it is necessary to adjust the trunnions and clamping bars.
• Cracking of the outer part of the translucent structure from the sun and precipitation – wooden profiles are subject to periodic maintenance and, if necessary, restoration of the surface.

If a window unit breaks down, it is best to get in touch with the brand’s service center while it is still under warranty. In the event of significant malfunctions, independent structural intervention may result in the loss of free service.
