Materials & Sustainability

ALONG WITH BEING RENOWNED FOR ITS STRENGTH AND AESTHETIC APPEAL, OAK IS INCREDIBLY SUSTAINABLE.

AT RICHOAK WE SELECT THE HIGHEST STANDARD MATERIALS TO ENSURE OUR CUSTOMERS RECEIVE EXCEPTIONAL QUALITY IN OUR PRODUCTS

We use both English and European oak in our frames, the only real difference being in the methods of cultivation. We prefer English oak, cultivated in local PEFC Accredited, mixed and deciduous woodland.

European oak, though genetically identical, to English oak, is cultivated in single species forests. This in turn creates competition between oak trees in growth, producing trees with much longer, straighter trunks ideal for use in the oak framing industry. English timbers seen in older oak framed buildings were traditional cultivated with this same method.

Green Oak

‘Green oak’ is oak in its most malleable form. It is recently felled and unseasoned so it retains moisture, it is this that results in it being more adaptable. Although being heavier than seasoned oak, green oak is regarded as being relatively easy to work with. As green oak dries over time, it strengthens and twists making the joints tighter and more robust.

Green oak is typically used in oak framed buildings for its strength and durability, but also for its attractiveness and fantastic weathering qualities. The timbers can be exposed both internally and externally and require no preservative treatment.

Steady Timber

After undergoing the initial drying out period, Green oak timbers become what’s regarded as “Steady timber”. Steady timber (due to its reduced moisture content) has been allowed to shrink, enabling cracks and defects in the timber to be identified. Detecting these areas enables us to eradicate unsuitable timbers, or incorporate them into the frame in a more convenient position.

Steady timber is used in areas where shrinkage and cracking could compromise the structural stability of a building, for example as lintels and where glazing is fitted. Where beams are to be internally exposed, steady timber is often used so as to provide an overall aesthetically pleasing appearance.

TILES & SLATES

We use both new, and reclaimed handmade clay roofing tiles and slates on all our buildings.

Handmade tiles add further beauty and character to any oak framed building giving an effect that cannot be replicated by any other roofing material.

Whether we’re restoring an existing roof, or installing a new one, the tiles we use are sure to improve the style and elegance of the building.

CLADDING

External cladding provides an ideal weather-sealant for any timber frame. It allows the frame to breathe, leaving ample room for insulation, and any movement or shrinkage of the timbers does not affect the weather-proof seal.

The cladding we use include seasoned oak, fresh oak butted boards and green English Douglas fir and cedar.

GLAZING

At RichOak we use certified triple glazed argon filled glazed units in all our buiildings.

We believe triple glazing is of higher quality than double glazing as it provides better thermal and sound insulation making it more energy efficient. We use three different methods of glass installation depending on your required aesthetic look and the positioning of the glass in the frame.

FULLY BEDDED GLAZING

This is a more attractive method of installing glazing into an oak frame. The glazing is applied directly into rebates within the frame. This method involves the use of quality oak, precise jointing and a low modulus silicon in a wide bead to increase flexibility as the oak shrinks and moves around the glazing over time.

DIRECT GLAZING – BY FAR OUR TRIED & TESTED PREFERRED OPTION

This method involves the glazing being fixed directly onto the outside surface of the oak frame. The glazing is secured to the frame using oak cover boards, these maintain the overall appearance of the oak frame. This technique allows the oak frame to move behind the glazing as it settles over time.

We also use the ‘normal’ framing method. Here windows and doors are installed into the oak frame in their individual frames. This means the glazing is not directly attached to the oak frame and therefore cannot be affected by the settling of the frame.

Sustainability

Timber is recognised as one of the only available renewable materials in construction. Along with being renowned for its strength and aesthetic appeal, oak is incredibly sustainable.

As trees grow, carbon dioxide is “locked up” in the wood, reducing atmospheric levels. This carbon dioxide remains in the timber until it is either released through combustion or returns to the natural carbon cycle.

At Richoak we are passionate about oak conservation and sustainability. We source the finest structural graded, green, English and/or European oak from our trusted suppliers.

All of our structural graded oak and softwood originates from sustainable and well-managed (certified) forests.
