Panels

Ready surface-treated panels are suitable for roof and wall paneling for residential rooms. Fully-painted panels
are suitable for dry rooms. Varnished, white-coated and sauna-protected panels can also be used in wet rooms.
Here are the formulas that can help you calculate product use, including loss:

15 x 95 – > square meters x 12 = required number of linear meters

14 x 120 -> square meters x 10 = required number of linear meters

With lumber, the amount of loss should always be estimated to be at least 10%.

Baseboards

Our baseboards are subject to a great deal of wear and tear. As a manufacturing material we use only high-
quality wood and hard MDF. Additional protection against chipping is provided by our special coat of paint or
varnish. This guarantees the longevity of the baseboards and the attractiveness of your home for their part.

Exterior cladding

Exterior cladding is the face of your home to the outside world. It is easy to make a home personable using
exterior cladding. Wood is easy to work and, when treated properly, is a good exterior cladding solution.

When choosing a suitable exterior panel, attention should be paid, for example, to the weather resistance,
serviceability and suitability of the panel in relation to the architectural details of the house. Ready-to-use
exterior finishing boards and panels must be primed before final surface painting. Surface painting must be
carried out twice. This will ensure the long-term durability of the cladding.

Pressure-impregnated wood

Pressurized wood is the absolute choice if the wood will be in contact with water or earth or constantly exposed to the elements. It is also advisable to use pressurized wood in weather-protected areas if, for structural reasons, the wood cannot easily be replaced or repaired.

How can pressure-impregnated wood be recycled? Or can I dispose of it myself by burning it or burying it?

Impregnated wood waste should always be taken to the recycling point at lumber yards or waste disposal facilities. They will ensure its
further delivery for energy recycling. Impregnated wood can only be burned in incinerators that have been issued with an
environmental permit. Impregnated wood must not be burned in home fireplaces and must not be buried. Impregnated wood
contains metal compounds that will spread into the surrounding nature if it is burned in an ordinary fire.

Can pressure-impregnated wood be painted? If so, what is the best type of paint to use?

Yes, as long as the wood to be painted is dry (humidity less than 18%). It is generally advisable to choose the summer following
construction to paint pressurized wooden structures. Garden furniture can be painted with oil paint, alkyd paint, translucent and
opaque wood stain or wood oil, although water-based latex paint should not be used.

Can pressure-impregnated wood be varnished?

The materials mentioned in the previous comment, i.e. outdoor paints and wood preservatives are suitable for processing.

How is pressure-impregnated wood labelled?

A label is attached to the wood at the impregnation plant. It displays, for example, the name of the relevant impregnation plant and
the wood preservation class of the impregnated lumber, which is also visible from the color of the label. White means Class A
impregnated wood and yellow Class AB.

Why is pressure-impregnated patio furniture the best choice?

Because non-impregnated wood cannot withstand the vagaries of weather. It begins to decay when the moisture content of the
structure rises above 18%. The moisture content of patio furniture often rises to over 20% and, in the case of ground contact, even
over 30%.

Will impregnated wood deteriorate or mildew if it is not looked after properly and maintained?

It will not decay or mildew. Mildew is prevented by the mildew-resistant substance used in the impregnation process. However, if the
conditions are very humid and ventilation is poor, mildew spots may appear on the surface of the wood. This kind of surface mildew
can be washed away with a mild detergent and a brush.
The surface of planed, impregnated wood can also lint and splinter as well as turn gray in sunlight, unless it is surface treated. Thus,
impregnated wood should be regularly oiled or protected using other surface treatment methods. It is a good idea to move patio
furniture inside for dry storage during the winter.

What is the best way to prevent pressurized wood from cracking?

Surface treatment after the wood has first been given time to dry.

How is patio furniture impregnated?

The material used is Class AB treated wood and copper compounds as an active substance. This kind of patio furniture is suitable for
all kinds of outdoor use and lasts 4–5 times longer than patio furniture made of untreated wood.

What causes the green color in treated wood? Is treated wood available in a different color?

The green color comes from the copper in the impregnation agent, but treated wood is also available in brown. Treated wood
becomes brown when brown pigment is added to the impregnation agent. Protecting wood with tinted wood preservatives is
worthwhile because brown wood tends to lighten in sunlight. The resistance of brown-treated wood to deterioration is comparable to
that of green- treated wood.

What changes have been made/will be made in relation to the impregnating agents used? Will the sale of pressurized wood continue?

Pressurized wood will continue to be sold. For over 50 years, CCA-impregnation agents with copper-chromium-arsenic compounds
have been used for impregnation. Arsenic is no longer used. Instead, it has been replaced by more environmentally-friendly
compounds.
