Flooring Systems

Stressline’s extensive range of prestressed flooring products allows estimators and designers to determine the most economical solution to satisfy your loading and span requirements.

Our flooring solutions include beam and block flooring, thermal flooring and hollowcore flooring. Full technical support and advice is available from product suitability, through to detailed design calculations, all free of charge.

Beam and Block

Stressline’s beam and block flooring system is a staple part of UK building. It is a robust, high quality system that can span up to 8 metres. It is generally designed for ground floor installation but can also be used for first floor installations in certain circumstances.

Thermal Flooring

The thermal flooring option is a lightweight, easy to install option that will help reduce the cold bridging in floors. Using Stylite T-beam technology, we offer a range of thermal flooring options which are used to help you achieve the required U-values for your project.

Our hollowcore flooring system is designed for first floor use, and is specifically designed with a self-weight of 300 kg/m2. This means both the 150mm and 200mm types will comply with the latest Building Regulations. Refer to part E for more information.

Thermal Flooring Installation

Our 3D Thermal Flooring Installation video is a step-by-step guide to help you understand how our thermal flooring works, and how it should be correctly installed.

Our Thermal Flooring uses Stylite T-Beam technology to reduce the cold bridging in floors, and improve the efficiency and ecological status of the build.

As well as Beam and Block, Hollowcore and Thermal Flooring products, we also offer an installation service for all our flooring items and bespoke precast stairs that perfectly compliment our flooring solutions.


Stressline has an on-going commitment to improving both product and management systems:
  • BSI Quality Assurance Accreditation to ISO 9001
  • BS EN ISO 9001
All of our products are delivered on flat bed articulated or rigid lorries, with the option of either self offload or crane offload.
The current lead time for flooring is 5-10 working days or 4-6 weeks for hollowcore.
A membrane is normally only required if there is a Radon or gases issue to deal with.
A void depth of 225mm is from lowest part of underside of floor. This would be underside of beam for beam and block floor or insulation panel for a thermal floor. Each is at a different level.
As part of floor components package we supply EPS strips to place around the edge of the floor. This is to create a thermal barrier with the perimeter walls.
Floor beams are manufactured in accordance with BS8110 which stipulates max camber of span divided by 300 i.e. 6.0m span divided by 300 = max camber of 20mm to be allowed for in construction
Our floors are designed to support the loads advised by the architect or structural engineer. The higher the imposed and line loads the more it effects the span the floor beams can achieve.
Yes, it is good practice to always lay a Damp Proof Course (DPC) beneath the floor beams and blocks bearing onto walls.
There are a variety of blocks available from lightweight aircrete to dense concrete. The weight of block will affect the span the floor beams can achieve. We normally design for 1350kg/m3 density. We would ask you to advise us if something different is needed.
The end panels are supported by the floor beam and pushed tight to the foundation wall. The friction between the deep panel and wall surface retains the panel whilst structural topping is applied.
Yes, it is good practice to bed the planks onto the supporting walls to seal any gaps from air, heat and sound loss into the cavities.
