Fascias, soffits and barges

WOF-Roofline

The term roofline is used as a generic term to describe the fascia, soffits, bargeboards and cladding that form the frontage adjacent to the roof and the eaves of most homes.

The difference between an attractive roof and an unsightly roof is often as simple as the appearance of the soffits and fascias and Welsh Oak Frame’s can provide a range of options that complement and enhance the overall design of your new home.

WOF-Joist 2

Unless your project is single storey, your oak frame will require a structural floor system which in essence will add further rigidly to the frame strength and offer a bearing surface for you to mount your chosen flooring material to.

Welsh Oak Frame offers a choice or combination of the following flooring products:

1. Softwood joists

Timber floor systems remain a popular choice amongst self-builders, probably due to the fact that they are a relatively inexpensive option as well as being straightforward to build and easy to adapt on site.  They typically span up to about 5m between structural walls with the end needing the support of galvanised steel joist hangers or built into the walls.
To prevent joists deflecting or moving, bracing in the form of herringbone strutting needs to be inserted between the joists, usually comprising purpose-made steel X struts and wooden noggin offcuts. Steel straps also help prevent movement by tying floors to the main walls.

2. Engineered I-joists

Also known as I-beams, this flooring system is strong and lightweight and can span 6m or more without support from internal walls or beams. They can also be installed in half the time. Their superior rigidity and strength-to-weight ratio makes for easier handling, and feature pre-formed knock out panels designed for pipes and cables to be threaded through. They can be cut to length and the webs can be drilled. I-joists are not prone to shrinking and warping making them perfect for quiet floors and therefore a popular choice for self-builders.

3. Open metal web joists

Open metal web joists feature a wavy metal web centre and are extremely strong and capable of achieving unrestricted spans of up to 7.5m. They are light enough to easily carry up a ladder with one hand and installation is quick. There is no need for bracing which helps to reduce labour costs and like I-joists they have the benefit of not being prone to shrinkage related problems.

Because the whole system is open, they can accommodate bulky service runs so are particularly suited to mechanical ventilation ducting and full bore 100mm waste pipes.

WOF-Glaze

Our own PAS24:2012 accredited direct glazing system certified by UKAS accredited test laboratory, Build Check Ltd.

WOF-Glaze

Today’s oak frame homes are notable for their large areas of glazing creating a seamless flow between the interior and garden space, truly bringing the “outdoors, indoors”.

Essentially, oak frame structures are built with “green oak”, which simply means that the timber will move slightly (shrink and expand) as the moisture content in the wood fibre changes. This has no impact on the structural integrity and strength of the frame however glass is a very rigid material, and if installed wrongly,  as the timber moves it could impose forces on the glass, which may crack or shatter at worst, or at least leave gaps for cold air draughts or rain water ingress.

Your oak frame can be designed to receive either pre-manufactured joinery products such as casement windows and doors, or you may wish to opt for a direct glazing system.

Welsh Oak Frame’s direct glazing system overcomes these challenges, where the glazing can be directly fitted into large frame sections, giving aesthetically appealing “walls of glass” which are structurally sound, weatherproof and draught proof. We use up to eleven separate elements, including different sealants, membranes, gaskets and foam adhesives, as well as specially kiln dried oak beading.

To meet Parts K (barrier) and Part Q (security) of current building regulations, Welsh Oak Frame have had their direct glazing system fully tested by UKAS accredited test laboratory, Buildcheck Ltd and now holds PAS24:2012 certification giving you peace of mind and the assurance that your glazing and oak frame will work in harmony together.

WOF-Wrap

External wrapping for airtightness

WOF-Wrap

Building regulations are constantly pushing towards building homes which are more airtight. The emphasis on the source of energy supply has now become subservient to levels of insulation and more increasingly, degree of air/wind tightness. For the healthy ‘breathing’ of the home there needs to be adequate means of controlling moisture levels within the house and fabric of the walls in order to avoid dampness and potential growth of fungal spores harmful to materials.

Your oak frame is no different from any other form of construction in terms of its ability to be wrapped. Air tightness tapes and membranes offer a simple way of achieving high levels of building air tightness. In order to gain optimum air tightness results, Welsh Oak Frame have developed a unique relationship with Ampack whose range of tapes and membranes are ideally suited to our style of oak framing and your choice of walling both internally and externally.

Welsh Oak Frame are happy to offer the full service for designing and fitting any external wrapping or provide on a supply only basis – the choice is yours.

WOF-Wall

WOF-Wall

When your oak frame is constructed you will need to think about what walling system you want to adopt. Inevitably the choice of external finish will be an aesthetic decision based upon the vernacular of your region or it may well be a planning condition which you need to adhere to. Either way, the external ‘skin’ is after all only a facade and a great deal of consideration will need to be given to the inner wall make up which provide any or all of the following:

  1. Additional structural stability to the oak frame
  2. Insulation layers to meet minimum Build Regulation requirements
  3. Moisture and vapour control and air tightness barriers
  4. Ease of construction

We are able to tailor a precise walling solution which meets our customer needs. There are many ways with which an oak frame can have a walling system attached to it which offer varying degrees of thermal performance, structural strength and aesthetic appeal. The two primary materials of choice within the WOF- WALL range include:

  1. Softwood frame
  2. Advanced softwood frame
  3. Structurally Insulated panels

Welsh Oak Frame’s team of oak frame designers ensure that our walling systems work seamlessly with your new home in terms of efficiency and air-tightness, at the same time not interfering with the overall design.
