Build Better, Build R-WALL!

Why R-WALL?

R-WALL Insulated Concrete Formwork offers a low carbon, environmentally friendly, quick build technique without compromise, producing high performance homes, with zero cold bridging, outstanding strength, performance and longevity. Building has to change to meet new ever increasing performance regulations, now's the time to be part of the future!

What is R-WALL?

R-WALL is a National and International, multi award winning Non-modular, Insulated Concrete Formwork (ICF) build system. Outer layers of R-Board (Extruded polystyrene XPS) are bound together by R-Rails and R-Ties. Courses are formed to desired height and the shuttered cavity is filled with concrete and allowed to set. This is now your finished wall resulting in a monolithic structure ready for render or cladding systems to be applied externally and plasterboard application/ first fix services internally. The R-Rails running horizontally through the system form convenient fixing points for plasterboard and claddings. R-WALL benefits from zero cold bridging, and performs as one of, if not the most energy efficient ICF's on the market. R-WALL can meet building regulations compliance with a 309mm wall further enhanced with exceptional PSI values. R-WALL can achieve U-Values as low as 0.1, easily achieving Passive house standard and below.

What makes R-WALL different?

So what makes R-WALL different to other ICFS on the market? R-WALL is non modular (not preformed blocks) which improves versatility and makes both the design and construction process much easier. The formwork uses a closed cell insulation which is up to 3 times the strength of other ICF systems, much more energy efficient and unaffected by water, ensuring both continued thermal performance and reduced build delays. R-WALL has zero cold bridging and therefore exceptional PSi values. Unlike most ICF systems R-WALL is fully UK based and produced. To find out more choose your Chanel from the options below;

Technical: Architect & Engineer

Design without restriction. Straight walls, curved walls, any angle of corner, change core sizes as required, alter insulation thicknesses internally and externally to achieve desired U-Values or aesthetic appearance. Easily achieve building regs compliance with zero cold bridging, U-Values as low as 0.1 and super airtightness characteristics.

Construction:
Developer & Builder

A quick build system that can be built in all weathers reducing construction delays! No requirement for heavy lifting equipment, improved health and safety on site and homes which out perform other build methods with little to no after care requirements. Easily meet building regulation compliance.

Performance:
Homeowner

A light weight build system which is versatile and easy to use. Onsite fully comprehensive training and support. Meet build schedules regardless of weather, be less reliant upon skilled labour.

The Future of Building

The building industry must change to build a better world for our future generations. Traditional construction and timber frame will struggle to meet the ever increasing energy efficiency standards. R-WALL is that solution, building homes more quickly with exceptional performance and expected longevity. Don't compromise with old traditional out dated techniques, future proof with R-WALL.

What can you build with R-WALL?

Residential

Detached, semi-detached and terrace houses. Flats (up 11m in height), extensions. The R-Boards can be rasped or modelled to mimic Victorian or Cob features.

Basements

R-WALL is unaffected by water therefore it is one of the few ICFs which can be used underground. R-WALL has exceptional strength creating retaining walls which also form the main structure of the home.

Commercial

R-WALL buildings are great for commercial use due to the exceptional sound attenuation and energy efficiencies of the buildings.

Pools & Ponds

Unlike EPS based ICF systems, R-WALL has very little compressive creep meaning the internal layer of insulation can remain in situ, forming a wall for liners or tiles, speeding up the build process and creating more energy efficient pools.

Retaining Walls

R-WALL has exceptional strength making retaining walls much quicker and easier to construct. Unlike modular ICF systems R-WALL can easily switch from one core size to another saving money and maximising build space.

Curves / Angles/ Cantilever's

With R-WALL their are no restrictions, the product can be used to create any angle of corner and any degree of curve!

R-WALL is made up of 4 components and with these 4 components you can build anything! The 4 components and their functions are detailed below.

1. R-Board
- Select your R-Board to select the energy efficiency of your superstructure

R-Boards are the insulation to your home and consist of XPS (Extruded Polystyrene) supplied in sizes of 2500mm long by 298mm high with thickness options as follows;

Eco -50mm (0.25 U-Value)

Standard - 75mm (0.18 U-Value)

Supreme -100mm (0.14 U-Value)

Superior - 125mm (0.11 U-Value)

Ultimate - 150mm (0.09 U-Value)

Any combination of board can be used internally or externally to the concrete core to achieve desired U-Values. This allows designs to better utilise Thermal Mass or altered for aesthetic purposes (e.g. adjusting insulation thickness to account for thicknesses of finishes).

2. R-Tie
- Select your R-Tie to determin your concrete wall thickness

R-Ties provide the strength during pour of concrete and their length dictates the wall or concrete thickness. The options available are as follows;

105mm or 4"

159mm or 6"

212mm or 8"

262mm or 10"

313mm or 12"

Any combination of board can be used internally or externally to the concrete core to achieve desired U-Values. This allows designs to better utilise Thermal Mass or for aesthetic purposes (e.g. adjusting insulation thickness to account for thicknesses of finishes).

3. R-Rail
- binds coursing horizontally and becomes a fixing point to internal and external finishings

The R-Rail is a recycled plastic length 1250mm in length which attaches to the selected R-Ties and sits into the R-Boards to bind coursings. The R-Rail after pour becomes fixing points for plasterboard (no dot and dabbing just screw straight in!) and claddings.

3. R-Corner
- a quick convenient way to form the perfect 90 degree corner

The R-Corner inserts into the formwork to fix and create easily the 90 degree corner. If alternate angles are required the R-Rail is extended into the corner and simply mitred to the desired angle. Easy!

R-Floor - Under slab Insulation System

To further compliment the R-WALL Formwork, why not choose the R-Floor Under slab system. The system seamlessly connects to the R-WALL, encasing the entire build in a full thermal envelope, preventing cold bridging and further enhancing the resulting energy efficiency of the home. Is this wasn't enough the R-Floor system is laid directly onto a sand blinding reducing concrete usage!

What our customers say

Mr Cummins

Brilliant product and exceptional customer service from Matt. So quick and easy to build and incredibly strong. This has got to be the future of building.

Mr Curtis

We wouldnt hesitate to recommend R-Wall. Fantastic service from start to finish with excellent on site assistance. This system is the future of building!

Mr Erwin

We couldn’t be more pleased with R-Wall. We have used other ICF systems in the past, but this system not only looks the best during construction but the strength of the product is amazing. Pour day was nothing but a pleasure, as was dealing with R-Wall from quote to completion. We would use them again and highly recommend to anyone wanting to build with ICF.
