Wall design
Provide sections showing framing, sheathing, membranes and finishes. Thermal, moisture, fire and acoustic requirements need to be considered at assembly level.

Commercial Stud Wall & Timber-Frame Spray Foam Insulation
Insulation for suitable accessible stud walls and framed constructions, coordinated with sheathing, services, membranes and linings.
Discuss your project →A specification built around your application
Stud-wall insulation needs to fit the complete wall build-up. Timber or metal framing, sheathing, external layers, internal linings and the proposed use influence product selection. Open-cell and closed-cell foams have different properties and should not be treated as interchangeable cavity fills.
Define whether the work concerns an open frame during construction or an existing lined partition. Exposed framing allows the substrate, services and installation depth to be assessed before spraying. An existing concealed cavity needs its own investigation and an appropriate installation method.
What shapes the insulation specification
Services and junctions
Coordinate sockets, cables, pipes, openings and interfaces with floors and ceilings. Components requiring access and specified gaps need to be respected.
Installation sequence
Agree when framing and preparation are ready, which inspections are required and when linings will be installed. Record the insulation before it is concealed.
Application photographs
Selected from the Duratite application library.

Read the project case study →From project brief to installation
Share the brief
Send photographs, dimensions, site location and the intended use. Include known defects and the outcome you need, such as reducing heat loss or addressing cold-surface condensation.
Assess the construction
The survey establishes the accessible substrate, preparation, moisture conditions and practical installation scope. Drawings and existing records help resolve interfaces with other parts of the building or vessel.
Agree the scope and price
Compare the complete work package: preparation, insulation, protective finish, access and reinstatement. Agree responsibilities and the programme before the work begins.
Record the completed work
Arrange inspection before the insulation is concealed. Keep the agreed specification, product details and installation records with the asset’s maintenance information.

Stud Wall & Timber-Frame Insulation questions
Should I choose open-cell or closed-cell foam?
The proposed construction and required performance should determine the product. The design needs to assess thermal, moisture, fire and any acoustic requirements.
Does foam replace fire stopping or acoustic design?
No. Fire stopping, linings and acoustic details remain separate design responsibilities. A foam product by itself does not establish the performance of a partition.
What affects the cost of stud wall & timber-frame insulation?
The treated area, substrate condition, specified thickness, preparation, access equipment and finish all influence the price. Include the work programme and any removal or reinstatement in the enquiry so quotations cover the same scope.
What should be agreed before installation?
Confirm the product and application, prepared substrate, intended thickness, junction details, protective finish and access arrangements. Ask for the relevant product information, installation records and the specific terms of any proposed warranty.
