Heavy building

• Formwork systems;
• Precasting.

Riga Poliform is a speciality formwork panel with superb mechanical properties and is designed to last longer with as many as 300 uses depending on specific end-use and site practice.

Features and benefits:

• Tough and impact resistant surface for smooth concrete finish.
• No rippling.
• As many as 300 reuses when correctly installed.
• Recycled wood fibres utilised in the wood-plastic overlay.
• Water resistant surface and weather resistant gluing.
• Surface is resistant to commonly used concrete release agents, diluted acids and alkalis, easy to clean with water or steam for repeated uses.
• Special solutions are available for applications requiring a higher surface elasticity such as nailing.
• Easy to machine and fix on site.
• Variety of standard sizes, cut-to-size and jointed panels available.
• Sustainable product with long life-span.

Further processing

Riga Poliform can be further processed according to customer's specification with cut-to-size, CNC, drilling, milling, jointing, edge machining, and assembling in sets.

Surface properties

The wood-plastic composite coating offers a highly durable, hard and dense surface, increasing panel resistance against mechanical damage and wearing. It resists concrete release agents, cement alkalis and other corrosive chemicals. The panels can be used within a temperature range from −40 °C up to +80 °C. Cold temperatures can reduce WPC flexibility making it less suitable for nailing. After use, panels release well and maintain their performance for a long time. Riga Wood experts will advise the most appropriate overlay depending on the end use.

Coating

The composite material is made of wood fibres and polypropylene, overlay thickness 0.8 mm or 1.6 mm. The coating covers both faces, upon request it is possible to coat the reverse side with film.

Two coating types available:

• WPC SP1 – high surface hardness for durability
• WPC SP2 – higher surface elasticity for nailing applications

Wear resistance

Surface hardness (Shore D Durometer) for WPC SP >72 HD; WPC SP2 >62 HD

Taber test (EN 438-2) up to 17,000 revolutions

Film colour

The standard colour is matt grey, other colours – blue, green, yellow, red, natural (without colour pigment).

One of the main components of the coating is recycled wood fibres (>40% of the volume). As wood is a natural material, changes in colour may develop during use, primarily as a result of sunlight exposure. Additionally, freshly produced panels may show slight colour

differences, as natural wood fibres can vary in tone.

Edge sealing

The edges are sealed with colour matched moisture resistant paint. Other colours are available upon request.
