WHY AND FOR WHAT PURPOSE CHOOSE LARCH BEAMS?
Larch beams have a cross-section of 100mm and larger (e.g. 150x150mm, 120x180mm and more), so it usually contains a centre in the axis of its cross-section, which results in larger extension cracks, which, however, in a limited amount does not affect the strength of the beam, it is more about the aesthetic effect.
Larch beams have a great application in all wooden constructions, both indoors and outdoors, for wooden roof trusses, larch ceiling beams and view trusses, pergolas, gazebos, fences, floors, terraces, facades and many others. At the customer’s request, we deliver larch beams planned, sanded, milled edges to the radius. Larch beams, but also smaller beams are widely used in the production of structural elements of various building structures.
Larch has a very nice and decorative appearance, but especially high durability when used outdoors. Larch lumber has the highest weather resistance of our coniferous woods. Larch lumber has a high durability even without surface treatment, due to its high content of resin and oily substances, which impregnate larch so well that it repels water. We also cut larch timbers to order in whole metres up to 12 metres in length.
LARCH WOOD FOR THE GARDEN
Larch beams are a cheaper option to oak and are just as incredibly durable and will obviously last for many years to come, and get even more beautiful with age. We can make larch beams with four sharp edges or just the required sight edge or side. The other edges can be rounded with bark.
Choosing larch timber beams is a neat way of landscaping your garden.
Whatever you need, a border, a vegetable or flower raised bed, steps, seating or even a pond, then our larch timbers are perfect for your project.
LARCH BEAMS FOR BUILDING RAISED PLANTERS?
A raised planter is perfect for the eco-friendly gardener, ideal for vegetable beds if you are thinking about self-sufficiency, offering more space for growing flowers and fruit or even creating a beautiful ornamental feature.
They are the perfect way to introduce a different type of soil to your garden and can help improve drainage for plants. Their relatively small footprint also makes them easier to work with and maintain.
We offer a range of shapes and sizes to suit your needs and available space, with pre-cut wooden components that make their construction quick and easy.
WHICH LARCH BEAMS CAN WE PRODUCE FOR YOU?
Rustic look with more knots and curves
Rustic larch beams highlight the natural beauty of larch wood without the perfect industrial edge treatment. Beams treated in this way will transport you back several centuries to a time when perfection was not emphasised. The more or less bark-free edges, small and large healthy knots remind you every time you look at this beautiful piece of wood that in the beginning it was a tree that grew for decades, with a natural curve rising behind the light with a lush branching in the crown. Logs with more branches (knots) cut off and not completely straight are used to make larch beams with a rustic look.
Rustic larch beams are suitable for larger square and rectangular dimensions of 150mm and more, e.g. in the form of a solid bench, table, design element in the interior and exterior.
Viewpoint sharp-angled appearance with fewer twists
In the production of the look larch beams and beams, we place emphasis on the quality of workmanship so that all edges are sharp without curves and a large number of large knots. The clean appearance and quality of the larch beams show the beauty of the larch wood and are suitable for structural and design elements of various small and large building elements.
The logs used for the production of larch look beams are the first and second pieces from the bottom of the tree with fewer cut branches (twigs) and minimal curvature.
View larch beams and prisms are suitable for use from smaller square and rectangular dimensions of 80mm and more, e.g. massive chairs, tables, design element in interior and exterior – gazebos, pergolas, view trusses and other massive structures
Freshly sawn (tarred) larch beams with unspecified moisture content
The disadvantage of using untreated sawn timber may be the high water content and the consequent volume changes and deformations when drying to equilibrium moisture content. The higher water content can also be problematic in terms of increased risk of attack by wood-boring insects, moulds and fungi, but this is to a small extent in larch, as larch is resistant to these attacks, as is oak.
When buying raw timber, it is a good idea to choose the right quality for the application. In general, centre sawn timber, ideally radial with no pith content, will be the strongest and most stable.
On the other hand, incorporating elements made from uncured timber with pulp content can cause undesirable effects in the form of twisting, drying cracks, etc.
This product of basic sawmill processing is not losing its popularity in traditional carpentry constructions, where a relatively wide range of cross-sectional dimensions is applied – their use is in gazebos, pergolas, trusses, exterior constructions, larch beams in the garden.
Technically dried, planed larch beams
The profiles are manufactured from technically dried larch sawn timber with guaranteed moisture content (usually 15% ± 3%). For larger dimensions above 120mm, they are produced as centre sawn timber or for smaller dimensions, the primary cutting of the log is done with care to cut through the pith (centre of the log). This guarantees higher dimensional stability.
Four-sided planing or sanding and chamfered edges are a matter of course – for ceiling beams and other visual elements we supply larch beams with planed, sanded, decoratively milled edges, grooves or hand planed.

TREAT THE LARCH BEAMS OR LET THEM TURN GREY?
Larch does not need surface treatment in outdoor conditions because it will last about 15 to 25 years without decay without direct contact with the ground. Untreated larch will turn grey in about 2-3 years due to sunlight and moisture. The colour changes first from the points that are most exposed to the weather and evens out over several years, depending on the conditions. The greying of the wood can be slowed down by treating the wood with transparent wood preservatives. A beam made from larch also does not need to be surface treated, as the larch material can withstand UV and moisture stresses. Over the years, however, the wood will turn grey. Remember that during greying, the tone of the surface may be uneven.
HOW LONG DO LARCH BEAMS LAST?
Larch beams, known for their natural durability and weather resistance, can last 20 to 30 years without significant wear and tear, as long as they are not in direct contact with the ground or moisture. In such conditions, it is recommended to use pressure-impregnated timber, which ensures a longer service life
Key properties of larch wood:
Natural durability: Larch contains a high proportion of resin, which increases its resistance to rot and pests.
Weather resistance: even without chemical treatment, larch is suitable for outdoor use
Aesthetics: larch has an attractive appearance that changes over time to an elegant silver-grey patina
To prolong the life of larch beams, it is important to regularly check their condition and apply protective coatings where necessary. These coatings help protect the wood from moisture and contamination
DO LARCH BEAMS NEED A PROTECTIVE COATING?
Larch beams usually require a protective coating to ensure their longevity and weather resistance. Protective coatings help protect the wood from moisture, which can lead to rot and other undesirable effects such as swelling
Types of protective coatings:
Lasers and oils: These products penetrate the wood and provide protection against UV rays and moisture. They are suitable for both indoor and outdoor use.
Impregnation: special impregnation, protects wood against mould and fungi
It is recommended that the condition of the coating is checked regularly and renewed as necessary to ensure maximum protection of the larch beams.
HOW TO CARE FOR LARCH BEAMS AFTER INSTALLATION?
Larch beams are a popular material for various construction projects due to their strength and durability. Once installed, it is important to pay attention to proper maintenance to ensure their longevity and preserve their appearance. Here are the key steps on how to care for larch beams:
Maintenance and treatment
Cleanliness: remove dust, dirt and bark residues regularly. This will help prevent rot and pest infestation.
Chemical treatment: it is recommended to use biocidal products that protect the wood from wood-boring insects and mould. These treatments should be carried out on the entire surface of the beams
Finishing: The application of protective coatings such as oils or varnishes can extend the life of the wood and preserve its natural appearance. These coatings should be applied regularly as recommended by the manufacturer
Inspection and repairs
Regular inspection: Inspect the joists regularly for signs of damage or pest infestation. Early identification of problems can prevent major damage
Repair: If you find damage such as cracks or rot, it is important to make repairs as soon as possible. You can use wood fillers or replace damaged parts
Weatherproofing
Covered location: if possible, place the larch beams in a covered area to protect them from direct sunlight and rain. This will help minimize warping and loss of color
Ventilation: Ensure good ventilation around the timbers to minimise moisture which can lead to rot
By following these recommendations, you can ensure that your larch beams remain in good condition for many years.
WHAT TO DO IF MOULD IS FOUND ON LARCH BEAMS?
When mould is found on larch beams, it is important to follow a systematic approach to ensure effective protection and prevention of future mould. Here are the recommended steps:
Identify and remove the mould
Mechanical removal: first, the affected areas must be mechanically cleaned. Use a scraper or brush to remove visible mold residue and contaminated wood parts.
Use a fungicide: Apply fungicide to the cleaned areas. Apply it to the affected area and leave it on according to the manufacturer’s instructions.
Maintenance and protection of wood
Impregnation with a protective product: After removing the mould, it is important to treat the wood with an impregnation. This product provides chemical protection against further mold and fungal infestation
Application of the coating: After the impregnation has dried (usually 24 hours), you can apply the primer to the wood and then the final coat
Prevention of future occurrence
Ensure good ventilation: make sure the area around the timbers is well ventilated to minimise moisture which can promote mould growth.
Regular maintenance: check the condition of the timber regularly and carry out preventative impregnation treatments at least every few years.
By following these steps, you can effectively remove mold from larch beams and protect them from future infestations.
