Being wind and watertight can be critical to financing a self build project, and can play an important role in managing energy use for the building ongoing.
Carpenter Oak work with several types of insulating panels which use a range of materials to suit different building specifications and budget. These can be preinstalled off-site to a bespoke design, saving build time on site and ensuring a perfect fit. U-values for panels vary based on their construction. We work with Warmcell to provide a natural fibre panel but also work directly with a range of synthetic materials also.
Carpenter Oak have extensive experience in integrating panels and timber frame design. This means that we utilise the quality and strength of both for complete building integrity. With 30 years of bespoke projects under our belt we can work with complex project design, and support self-builders to reach stage 4 of a self-build mortgage where needed.

Structural Insulated Panels (SIPs) are formed of an insulating foam core sandwiched between two layers of board, typically OSB (orientated strand board). We use these panels for walls, floors and roofs. They are manufactured under factory controlled conditions and can be fabricated to fit nearly all building designs.
Carpenter Oak Ltd have developed strong professional partnerships over the years with SIPs companies and can recommend a company to you to get the best quality and value for money – contact us for more information.
The main advantages include speed of build and better thermal and air leakage performance.
When used in conjunction with a frame, steel beams and glu-laminated beams are no longer required as the oak frame can support floors and roof panels.
With a pre-manufactured oak frame and pre-manufactured SIPs panels, a build can be made watertight in a matter of 5-6 weeks reducing labour costs and time lost to bad weather.
“With correct installation, the result is strong, energy efficient and cost-effective.”

Panels can have polyurethane or polystyrene cores, or panel systems are available with greener insulating materials such as shredded cellulose (Warmcell) or wool bats. The former have better insulating properties (lower U value) therefore make thinner panels, typically 142mm. The latter, less insulating materials may need to be 200 or 225mm thick to achieve the same U value.
Bearing in mind that the U value required for new building is due to increase to a higher standard, panels and therefore wall thicknesses will need to become thicker to comply with new regulations.
We have worked successfully with many SIPs panel manufacturers. The coordination between the frame and panels has to be exact; this is performed using CAD software. We make a model on the computer and send it to the SIPs manufacturer who then clads the frame with the panels. They then send their drawings to your architect to be checked over.

Please pass on our thanks to everyone who contributed to the work. We are aware that behind the people we speak to there are others who cut timber, drill joints and raise rafters, among other essential things, so our thanks to everyone involved. The oak frame is everything we expected.
I visited Chalkhill Cottage at the end of June 2010 to inspect the progress of works. I am extremely pleased to advise that my clients, together with myself, are delighted with the Green Oak Frame and wish to extend our thanks to Carpenter Oak. I understand that the frame erection caused much interest in the village and indeed whilst I was there people were stopping and viewing the works from the road and also a neighbour’s driveway! The extra mile that Carpenter Oak went, particularly with the client’s children, taking time to explain about oak, giving them hands-on opportunities, allowing their involvement in the construction, then finally issuing them with “apprentice certificates” was very much appreciated. Please pass on this note of thanks to all involved on the project and I personally look forward to working with Carpenter Oak on many projects in the future.
To the eye the quality of the finished product is excellent. Only time will prove how it works with the timber frame kit, but we love it! The carpenters were phenomenal! They are your best advert both in terms of their ability and approach. Led by Alex, with Geoff, Graham and Fergus from your yard at Loch of Lintrathen, Kirriemuir, Angus the frame was put up in the worst possible weather conditions. It was driving rain for the whole day, with the north east suffering flooding, but the team were as helpful and cheery at the end of the day as when they first arrived …real heroes
