StromaContracting
As the name suggests, STROMA Contracting provide a range of subcontract packages on large building projects, such as:
Dry-lining,
Partitioning,
Suspended ceilings,
Passive fire protection cavity barriers
& Acoustic or air sealing.
By working alongside our testing & consultancy operation (Stroma Technology), we can install these products to the required specifications while maintaining air-tightness.
STROMA are preferred by many of the UK's largest contractors and housebuilders. Our success is largely down to our wide ranging scope of products and services, together with a hard-earned reputation for customer support.
Stroma Contracting - Further Information
By using experienced operators and appropriate materials, we can cost-effectively deliver compliance for both Building Regulations Part B and Part L (with respect to air-tightness).
Stroma Contracting frequently carries out remedial air sealing work in completed buildings that have failed their air test. We typically work alongside our air-tightness testing colleagues to determine where air-sealing is required and even use test fans to constantly monitor our work and to ensure no air leakage paths remain.
Stroma Contracting provides all forms of passive fire protection on all types and sizes of buildings. Materials and methods can be selected to also satisfy the air sealing requirements.
Our service offering includes:
- Application of Intumescent Paint to Structural Steal The DFT (dry line thickness) is calculated using the HP/A (heating perimeter over area) as per BS 476 Part 21. Applied using an airless spray pump, the DFT will vary from 5 to 200mm, depending on the size of steel. A top-seal can be used for extra protection.
- Fire Compound to Vertical or Horizontal Penetrations The thickness of the fire compound will depend on the fire rating required. It is tested for up to 4 hours integrity and by including reinforcing steelwork within the compound, most products can become load bearing.
- Cavity and Void Barriers The installation of fire barriers to void openings can prevent the lateral spread of fire. Many types of barrier are used, from mineral fibre, woven glass to rigid boards. It can be an important part of the air-barrier.
- Sealing Service Penetrations Sealing service penetrations through any fire wall is important to maintain its integrity. This is usually carried out by sealing the void internally using coated fire-batts. For plastic and cast pipes, graphite collars are used to plug the hole. For cable trays requiring service accessibility, intumescent pillows can be used.
- Steelwork Protection using Rigid Boards Using the same method as with the paint (HP/A), we can calculate the type and thickness of board to provide the correct integrity. Various fixing methods can be employed from mechanical to dry fix.
Air Sealing: Whether as an integrated air-sealing and fire protection installation, or remedial works, perhaps following a failed air-leakage test, our extensive experience in both areas ensures a cost effective solution. Working with our air testing colleagues, we often use test fans to pressurise the building. This enables us to “find and fix” the problem areas using smoke pencils.

Dry Lining: All aspects of dry lining from walls, shaft walls to column encasements are undertaken.
