Other Materials

The beauty of Oak, and timber generally, is its versatility.

It can be used to sympathetically restore or extend historic buildings, or be harnessed to create striking modern spaces when partnered with steel, glazing, or insulated panelling.


Making complex or expansive timber framed spaces possible, steel can work as a subtle part of the construction, or a feature in its own right.

Our carpenters are experienced in combining timber and engineering, and in working with specialists to ensure quality and compliance in all our structures.

Steel can simplify structures by supporting clear and impressive roof spaces and arches. At the detail level, bolts, fixings and joints can be sleekly integrated, or used as character features. Steel provides additional strength, so is often partnered with timber in large or complex structures.

Being versed in the potential of timber engineering, our team can offer a wide range of structural solutions, design detailing and specifications that could not be achieved with wood alone. We ensure quality and compliance in all our structures.

Just like our wood, we only use quality steel materials. Our specialist suppliers also produce high specification fittings for yachts that are out in the elements all year round. In a building, these steel elements last a lifetime and beyond.



Timber framed buildings are energy efficient and comfortable places to live and work. Add thoughtful glazing design, and you can create truly impressive and light spaces with stunning views.

Our 30 years of experience means we are skilled in considering how glazing can best add to the atmosphere and performance of timber frame structures. We supply joinery for a range of fittings and fixtures which integrate glazing seamlessly into timber design.

A whole range of standard frames are available in double and triple glazing. Bespoke windows, panels and doors can also be included, depending on design and budget. We can also advise on solutions for managing solar gain or glare.

Structural Insulated Panels

To ensure air tightness, a stable internal temperature, and superior energy efficiency, many timber framed houses integrate a bespoke building wrap using Structural Insulated Panels or SIPs. These are wooden panels with a core of insulating material.

SIPs are made to measure, so can be used to create perfectly fitting floors, walls and roofs within the strength of an Oak frame. A range of insulation options are available. Synthetic insulation delivers good U-values and thin panels. A range of natural options, such as Warmcel (cellulose) or wood fibre, are increasingly competitive in terms of U-values and cost.

We use computer-aided design (CAD) to support the frame design process. This allows the frame designer, architect and SIP manufacturer to work together to ensure an exceptional fit.

SIPs, their role in your project, and the choice of insulating material can be discussed during the concept stage. The exact specification can be adjusted as the design evolves

Laminated Veneer Lumber (LVL) and Cross Laminated Timber (CLT)

LVL or CLT can form the internal element of an integrated insulation panel for wrap around building protection. Engineered from thin layers of wood, they provide an innovative approach to interior panelling for almost any house design.

Carpenter Oak’s unique specialisms within the commercial and residential sector are opening up new applications for LVL and CLT to enhance timber framed buildings. The use of LVL and CLT can enable a truly connected approach to timber-led design. This includes simplifying frame structures, and potentially lowering costs or build time through pre-installation.

These materials work exceptionally well in providing lateral support within timber frame buildings, as well as a beautiful finish – an effective and environmentally conscious alternative to plaster boarding.

LVL and CLT materials and their application has been more heavily developed across the channel. Our European cousins have found the potential to support a whole range of designs.

The use of LVL and CLT are swiftly becoming established building materials.
