TIMBER FRAMES

TIMBER FRAME SPECIALISTS

Timber framed buildings have become increasingly popular due to the well established benefits of on-site construction speed and price predictability.

The environmental credentials of using sustainable resources are also becoming more and more important to everyone involved with the procurement of construction projects.

SticX is a specialist structural timber company.

We design and build timber frames and other timber structures, including floors and roofs, utilising timber and engineered wood products.

Our structurally graded timber is imported from Scandinavia from demonstrably sustainable sources carrying PEFC certification.

We also design structures incorporating Glulam Beams and Cross-Laminated Timber technology.

Our designers work with the latest 3D CAD software packages, capable of integrating with the main architectural design software. We are also able to work within projects operating BIM.

SticX Open Panel Timber Frames – Prefabricated or Sticx-Built

This is timber framing in its simplest form. Purely the structure of the building, ready for insulating and first fix. It’s quick to site and can be prefabricated or SticX-built to suit the project.

Sticx Closed Panel Timber Frames – Prefabricated

Closed panels are simply prefabricated panels that have been insulated in the factory. The exact construction detail is determined by the level of insulation that the client requires.

The advantage over open panel systems is that it removes the process of having to install the insulation on site, which reduces site time and provides a superior standard of insulation. We take care to provide closed systems that help maintain air tightness whilst providing suitable space for cables and pipes to be run without damaging the vapour barrier.

Closed panel solutions also lead to a reduction in waste and, given enough space to site a crane, reduces the amount of manual handling with large sections of the building being lifted into place.

We are able to provide closed panels that achieve high levels of insulation with or without the use of PIRs.

Sticx Total Panel Timber Frames - Prefabricated

For clients looking for a total off-site wall panel solution, SticX is able to offer SticX Total Panels.

For projects with a high degree of repetition and standardisation, it makes sense to develop detailed wall designs, sufficient that entire walls of the building can be constructed off-site.

SticX takes its Closed Panel solution and adds to the prefabrication by delivering to site walls incorporating:

  • Windows and external doors.
  • First Fix electrics and plumbing.
  • Fixing points for kitchens and bathrooms.
  • Boarded internally for skim or paint finish.

A building utilising SticX Total Panels is ready for second fix and finishes, taking months off the build programme and managing quality and site risk more effectively.

The other advantage with this method is that it eliminates the need for dealing with risk associated with fire-during-construction– the product is enclosed with non-combustible boards.

Sticx Floor Cassette Systems

SticX utilises different joisting products on a project-by-project basis, including standard timber joists, pressed-web joists, metal-web joists, glulam beams, cross-laminated timber.

For most of our projects we look to pre-fabricate whole sections of floor, or cassettes as they are called in the industry. This can be done in the factory or, if there is sufficient space, on-site. The sections can be lifted into place by crane providing a safer and quicker method of erection.

QUESTIONS & ANSWERS

STICK-BUILT TIMBER FRAMES

Stick building is simply the construction of a timber frame on site utilising loose timber. It is a flexible system that avoids the need to pre-fabricate panels in a factory and is therefore cheaper, easier and quicker to procure.

PERFORMANCE

We can build anything that can be built in timber frame, including:

  • extensions;
  • bungalows;
  • houses; and
  • multi-storey buildings.

We have built frames up to 7 storeys.

We have a series of standard details for meeting clients’ thermal and acoustic insulation requirements. The end product is a timber frame, so robust details apply.

We have a specialist timber frame design engineer who provides us with the design and, as part of our service, carries out site inspection of the installation to check conformity with the design and standard detailing.

We don’t believe that SIP panels offer best value for money. Our frames are cheaper and easier to procure, yet can still achieve the necessary insulation values.

A frame’s sole purpose, after all, is to hold the building up; it isn’t on display, so why pay more?

QUALITY

We don’t believe that it is. We believe that off-site manufacture leads to compromises due to forming unnatural joints between panels. It’s very difficult to lap around corners or overlap fire protection boards when you have pre-manufactured panels.

Our experience is also that factory manufacturing doesn’t account for building tolerances. Often panels are altered on site to accommodate substructures which, whilst within site tolerances, mean the panels won’t fit.

We practise strict quality control with the materials that we use, the designs that we produce and site quality audits.

All of the structural timber that we use is treated with preservatives (Vac-Vac).

When stick-building we fit the boarding to the structure last, after the frame is up, and immediately fit the breather membrane. This means that the boarding is not subject to weather for long periods of time. Prefabricated panels have the external boards fitted in the factory and the boarding is therefore exposed to weather throughout the construction of the frame.

PROGRAMME

We believe that our system gives many programme advantages:

  1. The lead-in time is vastly reduced. We can turn a design around in a fortnight and, assuming everyone is happy with it, we can start straight away. We don’t have to fit in with a factory slot, we’re on site building.
  2. We can vary the speed of installation simply by boosting or reducing the number of operatives. The speed of panel construction is dictated by the number of cranes on site and their susceptibility to inclement weather and space restrictions.
  3. Similarly we can adjust our programme without worrying about factory production. We simply send more timber and more operatives... or vice versa. This helps with projects with a programme dictated by sales, for example.

COST

Stick-built frames will generally be 10-15% cheaper than prefabricated frames, because:

  1. We have no factory overhead.
  2. We have reduced crane costs.
  3. We use less timber.
  4. We have reduced transport costs.

HEALTH & SAFETY

We don’t believe that there are any significant disadvantages. The only real difference is that we do not rely on cranes for panel erection. This is because we are not dealing with the risk of manhandling large, heavy panels. We use the same tools and material as any other timber frame project.

SUSTAINABILITY

Timber is a sustainable resource and will assist anyone looking to achieve highly in BREEAM or the Code for Sustainable Homes. We believe that stick-building introduces a lower carbon footprint by not transporting material to and from a factory. Timber comes loose and is sourced locally to the site resulting in far fewer delivery miles.

Stick building also uses less timber as we don’t need to double up on studs to close panels, as a panel fabricator would. Subsequently we produce less waste and generally find we can use off-cuts for noggins and other site practices.
