WINDOW INSTALLATION

When installing windows, it is necessary to follow the Building Regulations ST 2491109.01: 2015 Installation of Windows, Doors and their Constructions.
ORDER OF WINDOW INSTALLATION WORKS

  1. Check the components and dimensions
  2. Determine the number of fitting points and method of installation
  3. Place the support and mounting blocks
  4. Place the product on the blocks
  5. Using the spirit level and changing the height of the blocks adjust the vertical and horizontal alignment of the product
  6. Place the product inside the hole
  7. Remove unnecessary mounting blocks
  8. Seal the gaps between the window frame and the edges of the hole

The specific mounting unit is selected for each customer individually, depending on the given situation. Sealing tapes and other additional materials are not included in the standard window installation.
NOTE. Before using the selected sealing materials, it is necessary to read their instructions for use.

OPERATING CONDITIONS FOR WOODEN WINDOWS AND DOORS

When using wooden windows, it is necessary to understand that this is a high-quality product that requires more maintenance than plastic windows. Installed products are often damaged during finishing works – products are sprayed with plastering mortars, glass units and frames get scratched, particles of construction waste enter the moving parts of the fittings; windows or doors get deformed and swell without observing the proper indoor microclimate (temperature and humidity). The relative humidity of the premises must not exceed 60%.

  • Ensure that the room is adequately ventilated and dehumidifiers are installed during finishing (plastering, concreting, puttying) and for several months afterwards, as increased humidity can cause mould on the frame, windows can get deformed (become leaky, difficult to open), varnished surfaces can turn white, the colour of wood can change. The shade of the coating and wood may change depending on the building materials with which the products are sprayed or have any contact. In this case, the products are irreparably damaged.
  • During finishing work, it is necessary to cover the products with transparent film, cardboard, etc., so that plaster, putty or paint does not get on painted, varnished surfaces, glass, locks, hinges and other fittings. Do not leave the film on for more than 3 days. After installation, be sure to make a tear in the film so that moisture does not accumulate between the film and the product.
  • Scratching the glass unit or frame will damage the product aesthetically. This type of defects can also rarely be eliminated without replacing the product or part with a new one.
  • If dust and particles generated during the plastering, puttying and sanding of walls get inside the fittings, they can get blocked, become difficult to use and, sometimes, even break. In addition, poorly closing sash can get deformed.
  • One of the most commonly overlooked conditions when using wooden windows and doors is the ambient microclimate. In case of unsuitable microclimate, the products swell and become deformed. As a result, they can start to rot, mould, become leaky and difficult to use.
ATTENTION.
  • Condensation on the inside of windows is one of the signs that the temperature-humidity ratio (microclimate) is inappropriate. Wooden windows and doors must be operated in rooms where there is no excessive moisture, as condensation formed on the windows or doors can affect the formation of mould, deformation of the glass units and the frame.
  • When finishing or repairing the premises, it is necessary to protect the windows accordingly so that the anti-corrosion coating or fittings are not damaged.
  • If you cover windows or doors to protect them from damage during construction or if you use shutters, be careful not to damage the glass and product frame.
  • To prevent the window or door fittings from breaking, do not overload the window sash, do not support it or lift it with additional objects.
  • Do not place any additional objects between the sash and the frame (do not jam wires, cables), as this may deform the window or door frame, fittings.
OPERATING THE INSULATING GLASS UNITS

Insulating glass units do not require any special maintenance. They need to be protected from factors that can result in cracking. Insulating glass units must be protected against slamming of the sash, which can be caused by drafts. Do not leave windows or doors open unattended. Leave them closed on very windy days.

  • All glass cleaning products are suitable for cleaning insulating glass units.
  • Do not use abrasive tools, razors, strong alkaline solutions, acids or hydrofluoric solutions to clean insulating glass units.
  • Do not attach any films to the glass (especially tinted glass). At different thermal stresses, the glass unit can crack.
  • The entire area of ​​tinted glass must be in the light or in the shade. With only a certain area in the shade, unevenly heated glass will crack.
  • If the glass is exposed to a temperature difference of more than 36°C, the probability of thermal cracking of the glass is greatly increased.
  • The distance between the heating appliances and the glass surface must be at least 20 cm.
  • Stoves, refrigerators must be at least 30 cm away from the glass surface.
  • The temperature generated by heating appliances near the glass must not exceed 65°C.
  • When you start heating the room, raise the temperature gradually, not abruptly.
  • Do not direct a stream of warm air at the glass when using heaters.
  • Refrigeration and air conditioning equipment near the glass can also cause the glass to crack.
  • Thermal cracking of the glass can also be caused by insufficient heat in the room (especially if it is not heated in winter).
  • The glass surface should never come into contact with the internal and external blinds – differences in surface temperatures may result in the glass unit cracking.
  • The distance between the blinds and the glass surface must be at least 2 cm.

Thermal cracks, cracks due to pressure changes or impacts are not covered by the warranty.
Cover the cracked glass with thick adhesive tape in various directions across the crack and cover the floor with cardboard or something else so that the falling glass does not damage the flooring. Contact professional glass installers or P. Varkojis ir Kompanija UAB.

MAINTENANCE OF WOODEN WINDOWS AND DOORS INCLUDES:
  • Maintenance of exterior and interior paint or varnish coatings
  • Checking and adjusting the functioning of the fittings
  • Checking the gaskets
  • Cleaning the gaskets, water drainage holes
  • Checking the glass
  • Applying a special care agent to the outside coating (not required for aluminium covers)

ATTENTION! Be careful when cleaning the windows, do not tip over. If necessary, use longer window cloths. Do not leave children unattended when cleaning open windows.

HOW TO CARE FOR PAINTED, VARNISHED COATINGS
  • To keep your wooden windows beautiful and free from damage, you must take care of the varnish or paint coating every year – clean them with wood coating care products. These products create a protective layer across the surface that protects against dirt, the coating becomes more elastic and glossy. You can apply these products with a cloth or sponge. The surface does not require additional polishing. Be sure to read the manufacturer’s instructions before using care products. The paint coating should be cleaned and lubricated once a year (e.g., before winter) and the varnish coating twice a year (preferably in autumn and spring).
  • If the shade of your windows or doors has changed, this is a natural result of exposure to environmental factors (sun, air, humidity).
  • Remove dust and dirt from surfaces at least twice a year. Failure to clean them can cause mould and lichens. Use a water-soaked sponge or cloth for clean surfaces. Do not use strong household cleaners as they may damage the varnish coating or the colour of varnish and wood may change. In addition, strong cleaners can damage the glass and window fittings.
  • Please read the instructions of the detergent manufacturers carefully and follow them. When cleaning masonry or other surfaces near the window, cover or otherwise protect the window. If acid cleaner gets on the surface of the window, rinse immediately with clean water.
  • Do not use powder or other abrasive cleaners (coarse or containing solid particles).
HOW TO REPAINT THE WINDOWS

Acrylic paints and varnishes are most suitable for your products. They will not create any unwanted reactions with gaskets and previous window or door coatings. We recommend eco-friendly Sherwin-Williams paint.
Before painting or varnishing the products, please read the basic painting recommendations:

  • Do not apply paint to sealing threads, gaskets, locks, handles, plastic trim, silicone threads on the glass unit, insect screen and other moving parts. You can buy these products in specialised building materials, repair and household supermarkets and stores.
  • Before painting, prepare the surface: sand the previous paint or varnish coating with sandpaper or a sanding sponge.
  • Remove the dust with a dry, soft cloth. Do not use abrasive or other surface-damaging cleaners.
  • Make sure that the painted surface does not get damaged by touching other surfaces before the paint is completely dry.
  • Before painting painted or varnished sashes of windows or doors, lubricate the gaskets with grease (e.g., cooking oil) so that they do not rip off the paint or varnish coating from the wooden surface before the coating gets completely dry.

ATTENTION. Sanding, chemical cleaning, painting, varnishing and other finishing work must be carried out in a well-ventilated room. Only paint open windows and do not close them before the paint has dried. The degreaser or primer must be completely dry before painting.

MAINTENANCE OF PANEL DOORS

Check the surface of the door regularly for any cracks, damaged corners/edges.
To ensure that your panel door serves you for a long time, wash it several times a year with a mild water-based detergent using a non-abrasive cloth that will not damage the top coat of paint. This will help to protect the door from accidental damage.
In case of discolouration or cracks in the door panel, it is recommended to restore the panel door:

  • Light-coloured surfaces of panel doors should be inspected and serviced once a year, and repainted every 5 years with an appropriate colour.
  • Dark-coloured surfaces of panel doors should be inspected and serviced every year, and repainted every 2 years with an appropriate colour (if they are exposed to direct sunlight and extreme conditions).

IMPORTANT. Dark-coloured surfaces of panel doors require more maintenance than light-coloured ones. Dark-coloured surfaces absorb more sunlight and heat up more; therefore, the panel becomes less stable and the paint covering its surface may crack. In addition, due to various environmental factors, the top coat can thin up to 20 microns per year. Therefore, thin protective systems need to be replaced frequently to restore the lost coating thickness and ensure adequate protection of the structures.
WARNING. Claims regarding cracks in the top coat of paint or panel of a door painted with RAL group 3 dark colours will not be accepted.

USING THE FITTINGS

Regular (at least once a year) lubrication of the hardware ensures easy operation and helps to prevent premature wear of the hardware. For lubrication, use exclusively machine oil or acid-free grease. It is also advisable to check the stability of the bolts regularly and tighten or replace them if necessary.
The windows will function for many years and the safety of users will be ensured if the following instructions are followed:

  • Do not turn the handle when the window is open
  • The window sash must not be loaded with any additional weight
  • Do not push the sash close to the soffit
  • Do not place any objects between the window frame and the sash

 

HOW TO CARE FOR GASKETS AND WATER DRAINAGE HOLES

When cleaning the windows, be sure to clean the gaskets as well. Various debris can damage or deform them.
When checking and cleaning the gaskets, open the sash to easily check for clogged condensate drainage holes in the aluminium downpipe attached to the bottom of the window frame. If there is debris or dirt in the holes, be sure to clean it so that the water escapes to the outside, otherwise it may accumulate on the frame and will leak inside the premises.

The holes are in the sashes. If these holes are clogged, water will accumulate between the frame and the glass unit. Eventually, due to the water-soaked glass unit, condensation begins to appear between the glasses, the selective coating oxidises, and stains appear. In addition, the accumulating water soaks the frame (it starts to rot) and the glass strips (they deform).

HOW TO CARE FOR PLASTIC AND ALUMINIUM PARTS

Clean plastic and aluminium parts with a mild solution of detergent and water. Wash with clean water; you can add a small amount of neutral or slightly alkaline detergent. The temperature of the mixture of water and detergent used for washing must not exceed 25°C. Powder coatings should not be washed with water vapour. Washing will be more effective if you use a soft, non-abrasive cloth to clean the powder coating.

Clean plastic and aluminium parts at least once in 12 months.
WARNING. Abrasive cleaners can scratch the surface of parts and damage the paint. Aluminium parts must not be cleaned with strong acids, strong alkaline detergents that react with aluminium surfaces.
