Blue at the core, green at heart, versatile by nature

Thanks to its close collaboration with industry professionals for nearly 4 decades, the wedi brand is well known for its high-quality, reliable XPS solutions that are easy and straightforward to fit offering fast installation and unbeatable durability.

Innovative wedi solutions - from building board systems through floor-level shower elements to preformed partition walls and functional design elements – have been under-going continuous development in order to fulfil the ever growing demand for sustainable, convenient and versatile system solutions in building construction.

wedi’s XPS elements are not only 100% waterproof to their core but also have the best BBA accredited vertical loadbearing (133kg/m²) and thermal (0.036 W/mK) properties amongst common foam tilebackers. They are manufactured with 100% green energy and with at least 25% recycled XPS foam material in a completely environmentally friendly process. What‘s more, wedi building boards and shower elements have internationally recognised Environmental Product Declarations that provide quantitative information of the environmental footprint throughout the entire life span of these products.

At the base of the wedi system is its core product the wedi building board. Exemplifying the word versatile, this XPS tilebacker is a true all-rounder:

• its 4mm thick version is perfect for floors
• used in 6mm thickness it creates a completely flush, levelled surface to existing tiles
• 10mm upwards it is perfect for use beneath electric underfloor heating
• its 12.5mm thick version provides a flush transition to existing plasterboards
• from 20mm thickness it is used for uneven wall surfaces
• 30mm upwards can be used to create bathroom furniture such as benches, niches, washstands etc.
• from 50mm it is approved for use as a free standing partition wall

In addition to the standard building board, the wedi system has more to offer. Prefabricated solutions, especially developed for different applications also play their part.

A building board with a pre-integrated vapour barrier, the wedi Vapor 85 building board provides an SD value of 92, making it ideally suited to high chloride environments. It guarantees an all-round protection: not only prevents water damage to the structural envelope of the building and maintains interior humidity levels in steam rooms, but also prevents heat loss and can be directly tiled onto. Due to its vapour retardant properties, the board can assist in protection of steel frames as well.

wedi PreLine building boards feature factory integrated grooves for the easy laying of hot-water pipes for underfloor heating systems. The reinforced surface then simply gets backfilled with flexible cement based tile adhesive and tiling can commence. Available in thicknesses of 30/40/50/60mm, thanks to its excellent thermal properties it reflects the heat back into the room, and as a result it improves underfloor heating systems response time by up to a staggering 70%!

The wedi Sanwell Wall is the perfect solution when looking for a ready-to-fit partition wall with integrated storage. Thanks to its 100mm thickness, this robust element includes a convenient niche and is available in two widths: 900 or 1200mm. With both the wall dimension as well as the niche dimension being customisable it truly offers a practical and straightforward solution for segregating different areas of the bathroom.

Quality, reliability, functionality and design paired with a straightforward, safe and quick installation form the basis of wedi Fundo shower systems. Whether a conventional shower element or a complete system with integrated drainage with either classic point or elegant linear drainage – the right flush-to-floor shower element can be found in the Fundo series. Featuring precise integrated slopes and 360˚ dry-fit drain technology, there a 10 designs, 3 different drain locations and numerous sizes to meet the high demand of planners, contractors and installers.

Benefits at a glance:

• No additional waterproofing or priming required before tiling– shortening the installation time, cutting back on labour and keeping required accessories to a minimum
• Direct-bond to metal and wooden stud frames – eliminating the laborious, time-consuming and risky steps to seal penetrations resulting from mechanical fixing
• Comprehensive seal owing to the waterproofness and low thermal conductivity of the material – offering throughout protection against mould and fungi as well as contributing to an energy efficient home

The watertight nature of wedi products is further enhanced by system accessories filling the ‘gaps’ – from Subliner sealing & decoupling membranes through specialist sealing sets to the industry famous wedi 610 for example – providing a systemised sealing solution that wedi is renowned for: the wedi system.

As a perfect complement to wedi building boards, wedi’s Subliner membranes (prefabricated waterproof membrane with a solid material thickness of just 0.5-0.8mm), can be used on existing substrates to waterproof, decouple or both.

The wedi Wall sealing set is a specially tailored set with all necessary components required for the reliable sealing of shower wall surfaces. It contains wedi Subliner Dry, wedi 520, wedi Tools sealing tapes and wedi Tools sealing gaiters.

Strength is in the details - required accessories by joint type:

wedi-to-wedi joints:

• for wet areas wedi 610 Adhesive sealant + self-adhesive Joint reinforcement tape
• for areas with constant high-humidity levels wedi 620 Sealant + Waterproof fleece tape

Transition joints a.k.a. wedi-to-non wedi joints:

• for up-to 10 linear metres: wedi Fundo Sealing set (Waterproof fleece tape + 520 Flexible sealant)
• for excessive joints (up-to 70 linear metres): 520 Flexible sealant + Waterproof fleece tape

Furthermore, wedi is the only XPS manufacturing company whose products have received the European Technical Approval for sealing of floors and walls in wet rooms – as a result, no additional sealing is required and the enclosure would be awarded not only with a full system warranty signed and sealed by wedi but also a CE mark.

Declaring the utmost quality of its products and hence the functionality of its systems, far beyond the manufacturer’s warranty wedi also offers a ‚voluntary‘ 10 year product quality guarantee on its entire standard product range.

High-quality installations however depend not only on great products but also on knowledge and experience using them and so, in order to deliver the systemised sealing solution, the brand is renowned for, wedi offers training sessions and even on-site training for qualifying projects.
