WPC Square Louver
Clean square-section grid.
The TSS WPC Square Louver is a wood-plastic composite profile with a clean, equal-sided square section, engineered to build crisp linear grids across ceilings, partitions and feature screens. Spaced on a regular pitch, the square bars read as a calm, contemporary rhythm that organises a space, conceals ductwork, lighting tracks and services overhead, and filters daylight or artificial light without fully closing the plane. The composite construction pairs the warmth and grain of timber with the dimensional stability of a polymer matrix, so the finished grid holds its line where natural wood would move.
The TSS WPC Square Louver is a wood-plastic composite profile with a clean, equal-sided square section, engineered to build crisp linear grids across ceilings, partitions and feature screens. Spaced on a regular pitch, the square bars read as a calm, contemporary rhythm that organises a space, conceals ductwork, lighting tracks and services overhead, and filters daylight or artificial light without fully closing the plane. The composite construction pairs the warmth and grain of timber with the dimensional stability of a polymer matrix, so the finished grid holds its line where natural wood would move.
Manufactured from a homogeneous blend of wood fibre and virgin polymer with UV stabilisers and coupling agents, the louver resists moisture, splitting and insect attack and carries its colour through the section rather than as a surface coat. This makes it suitable for interior schemes and for sheltered exterior applications such as soffits and covered façades, where it weathers predictably and needs no painting or sealing. Surfaces arrive in a range of natural wood tones with a fine embossed grain.
Supplied to TSS Building Material Division across Europe, North America and beyond, the WPC Square Louver ships with full technical documentation and is dimensioned to mount quickly onto battens, sub-frames or proprietary track. Sections, pitches and tones are coordinated for repeatable, low-tolerance installation on projects of any scale.

▸Ceiling features
Suspended square-bar grids that define zones overhead while concealing ducting, sprinkler runs and lighting tracks.
▸Room dividers
Free-standing or floor-to-ceiling screens that separate spaces without blocking light or sightlines.
▸Reception screens
Feature backdrops and counter screens that give arrival areas a warm, contemporary timber rhythm.
▸Soffits
Sheltered external undersides and covered walkways where a weather-stable grid finishes the eave or canopy.
▸Feature walls
Vertical batten-grid panels that add depth and texture to lobbies, corridors and retail fit-outs.
▸Crisp grid
Equal square sections sit on a regular pitch to read as a clean, precise linear pattern.
▸Hides services
The open grid masks ductwork, wiring and fixings while keeping access from above.
▸Durable
Moisture-, split- and insect-resistant composite holds its shape far better than natural timber.
▸Quick to mount
Consistent sections fix rapidly to battens, sub-frames or proprietary track with minimal cutting.
▸Through-colour
Wood tone runs through the section, so knocks and cut ends stay discreet and need no painting.
EN 15534
Composites made from cellulose-based materials and thermoplastics (WPC) — characteristics and test methods for profiles and cladding.
EN 13501-1
Reaction-to-fire classification of construction products; WPC profiles of this class typically achieve Euroclass D-s2,d0.
EN ISO 16474 / ASTM G154
Accelerated weathering and UV exposure test methods used to verify colour and surface durability for exterior use.
CE marking
Declaration of conformity to the applicable harmonised requirements for placing the product on the European market.
ISO 9001
Quality management system governing manufacturing, inspection and traceability of supplied material.
- ▸Acclimatise bundles flat on site for 24–48 hours before fixing, and leave a small expansion gap at runs and abutments to absorb thermal movement.
- ▸Mount onto a true, level batten or sub-frame at regular centres; pre-drill and use corrosion-resistant fixings, allowing clearance holes for movement on longer runs.
- ▸Set out the grid pitch from a datum line and work to a story pole so spacing stays consistent across the full plane.
- ▸Cut with fine-tooth carbide blades for clean square ends; de-burr edges before assembly.
- ▸For sheltered exterior use, ensure the sub-frame is ventilated and drained, and keep profiles clear of standing water.
- ▸Wipe finished surfaces with a mild detergent and soft cloth; no sealing, oiling or painting is required.

Stock tones and standard sections typically dispatch within 7–10 working days, while bespoke sizes, pitches and colour matches are made to order on a 3–4 week lead time; physical samples and tone swatches are available for approval before commitment. Every consignment ships with full documentation — a Technical Data Sheet, reaction-to-fire and weathering test reports, a Declaration of Performance with CE marking and a product warranty — and TSS Building Material Division supplies the WPC Square Louver across Europe, North America and beyond with complete export paperwork for each shipment.
WPC Square Louver
questions.
Yes, in sheltered exterior positions such as soffits, canopies and covered façades. The UV-stabilised, through-colour composite weathers predictably; it should be installed on a ventilated, drained sub-frame and kept clear of standing water.
A 50 x 50 mm square section in 2.9 m standard lengths is typical, with 40 x 40 mm and 30 x 30 mm options. Profiles can be cut to order, and grid pitch is coordinated to your setting-out.
WPC profiles of this class typically achieve Euroclass D-s2,d0 to EN 13501-1. The applicable classification report is issued with each order; confirm the rating required by your project specification when requesting a quote.
No. The wood tone runs through the section and the surface is finished as supplied, so the louver needs no painting, sealing or oiling — only an occasional wipe with mild detergent.
It mounts onto battens, a sub-frame or proprietary track with corrosion-resistant fixings. WPC has measurable thermal movement, so leave expansion gaps and use clearance holes on longer runs as set out in the installation notes.
Standard tones include Teak, Walnut, Oak, Coffee and Charcoal, and bespoke colour matching is available to order. Request swatches for approval before placing a production order.
Yes. TSS Building Material Division supplies across Europe, North America and beyond, and every shipment includes the Technical Data Sheet, test reports, Declaration of Performance with CE marking, warranty and full export documentation.
