WPC Rectangular Louver
Bold horizontal lines.
WPC Rectangular Louver is engineered for designers who want bolder rhythm and longer clear spans than a slim batten can give. The flat-faced rectangular profile casts strong, well-defined shadow lines across a façade through the day, reading as a confident horizontal grain on entrances, screens and balustrade infills. Built from wood-plastic composite, it pairs the warmth of timber tones with the dimensional stability and weather resistance of a polymer matrix.
WPC Rectangular Louver is engineered for designers who want bolder rhythm and longer clear spans than a slim batten can give. The flat-faced rectangular profile casts strong, well-defined shadow lines across a façade through the day, reading as a confident horizontal grain on entrances, screens and balustrade infills. Built from wood-plastic composite, it pairs the warmth of timber tones with the dimensional stability and weather resistance of a polymer matrix.
Because the section is deeper and wider than a standard square batten, fewer pieces are needed to close a given area, which speeds installation and keeps the supporting framework economical over large elevations. The material is colour-consistent through the profile, resists splitting, warping and insect attack, and needs no painting, staining or sealing once fixed — only occasional washing to keep the surface fresh.
Supplied to representative EN and ASTM performance criteria with CE marking and a documented quality system, the louver is delivered across Europe, North America and beyond as a complete screening solution with fixing guidance, matched accessories and full technical documentation.

▸Façade screening
Wide rectangular sections close large elevations efficiently while delivering strong, architectural shadow lines.
▸Entrance features
A bold horizontal screen frames lobbies and main doorways with a warm timber-tone finish.
▸Car-park screens
Durable, low-maintenance louvers provide ventilated visual screening for decks and parking structures.
▸Balustrade infills
Horizontal louver fields create privacy and rhythm to balconies, terraces and walkway edges.
▸Boundary and plant screens
Conceals services, bin stores and compounds with a clean, weatherproof finish.
▸Wide spans
The deeper, wider section bridges greater distances so fewer members and less framework are required.
▸Strong shadow lines
Flat rectangular faces cast bold, defined shadows that shift with the sun for a dynamic elevation.
▸Weatherproof
The colour-stabilised composite resists moisture, rot, warping and insect attack outdoors.
▸Low upkeep
No painting, staining or sealing — an occasional wash keeps the surface looking fresh.
▸Colour-consistent body
Tone runs through the profile, so cut ends and minor marks stay visually discreet.
EN 13501-1
Reaction-to-fire classification of construction products; this louver is typically supplied to Class E, with a B-s1,d0 grade available on request.
EN 15534 (1 & 5)
Wood-plastic composites (WPC) for construction — material characterisation and requirements for profiles and cladding/decking applications.
ISO 9001
Quality management system governing manufacture, inspection and documentation for consistent, traceable supply.
CE marking
Conformity with the applicable European product and construction-product requirements for placing on the EEA market.
ASTM D7032
Performance rating method for WPC products (mechanical and durability classification) for North American specification.
- ▸Fix to a true, ventilated aluminium or steel sub-frame; do not mount directly onto sealed wet substrates.
- ▸Allow expansion gaps at member ends and abutments to accommodate thermal movement of the composite.
- ▸Use concealed clips or manufacturer-recommended stainless fixings; pre-drill and avoid over-tightening face fixings.
- ▸Set consistent gaps between louvers with spacers to keep shadow lines even across the run.
- ▸Support long spans at recommended centres to prevent deflection and maintain a flat, aligned face.
- ▸Store flat, bundled and supported off the ground; protect from prolonged point loads before fixing.

Popular profiles, lengths and wood tones are typically held in stock for short lead times, while bespoke sections, colours, fire-rated grades and cut-to-size orders are produced to order with indicative lead times confirmed at enquiry; representative samples and finish swatches are available before commitment. Every consignment is supported by full documentation — technical data sheet, reaction-to-fire and WPC performance test reports, CE declaration and a product warranty — and is delivered with appropriate export crating across Europe, North America and beyond, with complete shipping and conformity paperwork.
WPC Rectangular Louver
questions.
The deeper rectangular section spans further than a slim batten; exact unsupported spans depend on the profile chosen, so we confirm framework centres and section against your elevation at enquiry.
No. The wood-plastic composite is finished and colour-stable from manufacture; it requires no painting, staining or sealing — only periodic washing.
Profiles are typically supplied to Class E under EN 13501-1, with an upgraded B-s1,d0 grade available where the project specification requires it.
Yes. They are exterior grade with a colour-stabilised polymer matrix that resists moisture, UV, rot and insect attack; stainless fixings are recommended in marine environments.
Yes — lengths can be supplied cut-to-size, and standard tones include walnut, teak, oak, charcoal and grey, with embossed or brushed matt surfaces.
They mount to a ventilated aluminium or steel sub-frame using concealed clips or recommended stainless fixings, with expansion gaps and even spacing for consistent shadow lines.
Yes. We supply across Europe, North America and beyond with full documentation — TDS, test reports, CE declaration and warranty — and appropriate export packaging.
