I-Joist Flooring Systems
Our Engineered Timber Department was launched over 25 years ago and has grown to become one of the largest suppliers of Steico manufactured I-Joists, I-beams and laminated veneer lumber (LVL) in the North of England.
At JT Atkinson, we design and cut all of our I-joist flooring systems using innovative Steico I-Joists, Posi-Joists & Simpsons Strongtie Joist Hangers. Today JT Atkinson supply hundreds of sites across northern England.
What is an I-Joist?
I-BEAMS AND I-JOISTS ARE A STATE OF THE ART SOLUTION FOR ROOFS, FLOORS AND WALLS
An I-Joist is an engineered wood joist, designed to eliminate the problems that occur when using timber joists. I-joists are quick and easy to install and do not distort or split like traditional joists. With virtually no shrinkage, there is little risk of developing bouncy or squeaky floors.
The functional principle for I-joists is as simple as it is impressive: reduction. Where no material is needed, no material is wasted. The result: improved properties with low weight, low primary energy consumption and maximum energy efficiency.
Applications of I-Joists.
Our I-joist systems can be used wherever conventional load bearing structures made of wood are used – in wall constructions as well as in roof and floor constructions. I-joists are a great alternative to timber joists.
I-joists are the most common way to structurally frame an upper floor in a residential building. I-joists are also commonly used in flat roofs for both residential and commercial buildings and are used for:
- Floor joists
- Roof rafters
- Wall studs
Benefits of I-Joists
Easy handling & installation
Minimises thermal bridge
No shrinkage or twisting
Long continuous spans
Reduced site wastage
Environmentally sustainable
Benefits of I-Joists
How I-Joists are made
I-Beams for Floors
Engineers have long recognised the advantages of an I-section in structural elements. Suitable material is only used in those places where it meets the needs, resulting in a slender and economical building element for floors, walls and roofs. Modern structures require high performance and cost efficient constructions in which shrinkage and movement are a thing of the past. The carefully selected components used in the flange and web create a high quality engineered wood product. Our engineered wood joists are designed to reduce movement and other problems associated with solid timber floors. Thanks to its engineered properties the STEICOjoist is dimensionally stable, avoiding the need for mid span blocking to be installed and reduces the risk of nail popping in plasterboard caused by timber shrinkage. New floors are easily incorporated into renovation projects where access is limited and handling issues are important, due to the light-weight properties of our engineered timber floor joists.
I-Beams for Roofs
The STEICOjoist is a lightweight, high performance engineered wood joist for roofs. The easy to install rafters and can provide clear spanning solutions in excess of 10 m. This allows fast and efficient installation by the end user and provides highly insulated roof constructions.
I-Beams for Walls
STEICOwall is a slender engineered timber joist for stud wall construction that demands a high level of energy efficiency and strength. STEICOwall engineered wood joists are available as a pre-insulated version which facilitates easy insulation of the structure and contributes to cost savings.
Chipboard Flooring
We stock a wide range of tongue & groove particleboard flooring for domestic & commerical use. Our Egger Peel Clean Xtra flooring can be left exposed to the elements for up to 60 days and provides a clean finished floor with an added moisture barrier when the film is removed. Flooring, CLS, ironmongery and joists will all be delivered together in kit form.
Hangers & Ironmongery
When we design, spec and quote your floor we always include appropriate products for your project within your kit.
Everything you need arrives in one single delivery, and our range of ironmongery solutions are just the answer to ensure that your installation runs smoothly.
We will box all of your required ironmongery per plot.
Laminated Veneer Lumber (LVL)
LVL is one of the most stable wood-based materials. It consists of several layers of approx. 3 mm thick softwood veneers (spruce / pine) that are glued together. This spreads any imperfections evenly over the cross-section, making it as homogenous as can be.
Thanks to its unique structure of bonded softwood veneers, the result is a wood-based material with the highest strengths – for extreme load-bearing capacity where it counts.
