Siberian Larch (Decking Boards)

Siberian larch is a coniferous species with high density and natural resin content, used outdoors primarily for decking boards under pergolas and around saunas and hot tubs. Slow growth in a cold climate produces a dense, finely structured wood grain with higher mechanical strength than common Central European conifers. High resin content acts as a […]

HARVIA Lighting

Harvia lighting is a range of lighting solutions from the Finnish sauna technology manufacturer Harvia, designed for both sauna interiors and exteriors. It includes light strips, spotlights and fibre-optic sets that are installed into the ceiling, benches or around the cabin door. The products are designed to operate at the high temperature and humidity of […]

RGB Lighting (Wellness Technology)

RGB lighting is a colour LED lighting technology based on combining three primary colour diodes, red, green and blue, which mix to produce a wide spectrum of colours and shades. In hot tubs, saunas and cooling tubs, RGB diodes are integrated into the structure, most often below the waterline, into benches, or into the cabin […]

Pine Cladding

Pine cladding is an interior or exterior covering made of pine wood, used for the walls, ceilings or facade elements of saunas, pergolas and wellness structures. Pine is a softwood species with a light, strongly figured surface and visible knots. In its raw state, it has higher thermal conductivity and resin content than species intended […]

PVC Flooring (Wellness Areas)

PVC flooring is a polyvinyl chloride wearing layer intended for areas in permanent contact with water and high humidity, such as shower zones, the surrounds of hot tubs, or the technical areas of wellness cabins. The material is supplied as homogeneous or heterogeneous sheets or tiles, which are welded into a continuous, watertight surface without […]

Ventilation (Sauna and Wellness Cabins)

Ventilation is a system of controlled air exchange in a sauna or wellness cabin that supplies fresh air and removes moisture and heat once use has finished. In a Finnish sauna, air flows from the inlet vent near the heater towards the outlet vent on the opposite side of the cabin, creating even airflow without […]

Shower Zone (Wellness Area)

The shower zone is a functional part of the wellness area intended for rinsing the body before and after sauna use or bathing in a hot tub. For hygiene and operational reasons, it is separated from the sauna and hot tub by its own floor covering and drainage, capable of withstanding permanent contact with water. […]

PAROC 10 cm Insulation (Roof and Floor Insulation)

PAROC 10 cm is a 100 mm thick stone (mineral) wool insulation used mainly for the roof and floor in sauna and wellness cabin construction. The roof and floor face a larger temperature difference against the exterior than the walls, so they require a thicker insulating layer to maintain a stable cabin temperature. The material […]

Drainage System (Pergola and Terrace)

A drainage system is a set of structural elements that carry rainwater and condensation away from a pergola, terrace or sauna roof, clear of the structure and its foundations. In aluminium pergolas, a drainage channel carries rainwater from the closed louvres through the supporting columns directly into the ground or into a connection to the […]

Spruce Wood (Cladding and Structure)

Spruce wood is a softwood species commonly used in Central and Northern Europe for wall cladding, structural elements and exterior decking on saunas and pergolas. Spruce has a light colour, a straight grain and a lower density, which makes it easier to work and reduces structural weight. In its raw state it has higher thermal […]

Aspen Wood (Sauna Benches)

Aspen wood is a soft hardwood commonly used for sauna benches, backrests and other interior contact surfaces, thanks to its low thermal conductivity and light, even appearance. Aspen contains no resin, which eliminates the risk of a sticky surface or heat-induced staining. The wood has a low density and a fine grain, keeping the surface […]

Lime Wood (Sauna Interior)

Lime wood is a soft hardwood used in sauna interiors for wall and ceiling cladding, and in some cases for benches. Lime has a light, almost white colour, a fine, even grain with no pronounced knots, and a low resin content. These properties reduce the risk of staining or a sticky surface at high sauna […]

Metal Roofing (Saunas and Wellness Structures)

Metal roofing is a covering made from shaped metal sheet, most commonly coated galvanised steel or aluminium, used on saunas, pergolas and wellness structures. It comes as trapezoidal profile, standing-seam panels or tile-effect sheets, with individual strips joined by overlap or seaming that keeps the roof watertight without fasteners penetrating the covering surface. Compared with […]

PAROC 5 Insulation (Wall Mineral Wool)

PAROC 5 is a 50 mm stone (mineral) wool insulation used mainly for wall cladding in sauna and wellness cabin construction. The material is produced by melting basalt and other mineral raw materials at high temperature and spinning the melt into insulating fibre boards. The fibrous structure traps air in small pockets, which limits heat […]

Bitumen shingle (Hexagonal)

Bitumen shingles (hexagonal) are roofing materials made from a glass or organic base mat impregnated with oxidised or modified bitumen and coated with mineral granules. The hexagonal shape creates a distinctive honeycomb pattern, which ensures even overlap and effective water drainage. This type of roofing is used on the roofs of saunas, pergolas, garden sheds […]
