Over recent years, industry professionals have increased the size of external wall studs from 90mm to 140mm in order to improve timber frame U-values and create an effective insulation wrap. Unfortunately this has caused wall thickness to increase dramatically.
Celotex XR4140 timber frame insulation slab is an easy and quick installation solution with superior thermal performance, fire classification and acoustic properties. Furthermore, this product boasts significant environmental advantages with an A rating from Green Guide.
Rigidity
With 140mm timber frame insulation, you can build advanced timber frame wall constructions that meet UK thermal building regulations. These systems typically come equipped with foil-faced insulation that remains in place even as timber studs move. Furthermore, this technology helps create walls with low construction U-values resulting in lower energy costs for your energy consumption needs.
Earthwool Frametherm 32 between studs and clad can help achieve an outstanding U-value of 0.17 W/m2K while simultaneously permitting deeper window reveals.
Kingspan ThermaWall TW55 insulation boards provide another viable option. Designed for use between timber and steel framing wall studs, the product features cores with facings resistant to mold, fungi, vermin and damp. Furthermore, their aluminium facings have low emissivity surfaces to further decrease heat loss.
Durability
Timber framing is highly durable and, when treated appropriately for climate conditions, can last an impressively long time. To maximize longevity of timber frames it is vital to identify and assess risk factors during construction such as termites, moisture issues and condensation absorbing insulation. Furthermore, extra termite protection might be required; in such an instance it would be wise to research different options as soon as possible before selecting one treatment type over another.
140mm insulation utilizes materials like Isover Timber Frame Batt 35, an advanced glass mineral wool slab designed to friction fit between timber studs of external walls, to meet Part L Building Regulations. When combined with PIR (polyisocyanurate) rigid foam insulation it achieves impressive U-values (calculated and published by one of the leading manufacturers) proving timber framed buildings can match steel-framed ones when designed properly – showing timber’s ability to achieve energy performance comparable to that of steel framed buildings when properly designed – unlike steel-framed buildings – while Kingspan ThermaWall TW55s core/facings provide non-hygroscopic properties while not providing food value to vermin populations either!
Thermal conductivity
Timber frame structures utilize an air gap between their inner structural panels and outer cladding skins for ventilation purposes. To optimize performance of timber frame walls, the space can be insulated to add insulation but must remain free from obstructions such as obstructions and materials that block ventilation.
Published data indicates that walls made with 140mm Earthwool Frametherm 32 insulation with brick veneer can achieve an outstanding U value of 0.17 W/m2K; an impressive feat given that gaps must remain clear.
Glass mineral wool insulation boasts low thermal conductivity and excellent acoustic properties, in addition to having outstanding fire resistance – earning Euroclass A1 fire classification status.
Pre-cut to 570mm wide for easy installation between common stud spacings with friction fit, this insulation comes ready-cut and requires minimal on site cutting or wasteful wasteful cutting to install between common stud spacings with minimum effort and waste. Made from 84% recycled glass material for reduced carbon emissions. Additionally it acts as a barrier against air infiltration and moisture vapour movement while offering zero potential ozone depletion potential or negative carbon footprint.
Fire resistance
This BBA-certified product combines excellent thermal and acoustic performance for timber frame walls, making it suitable for meeting Part E of England and Wales Building Regulations. With an extremely low thermal conductivity of 0.03 W/mK and resistance to moisture vapour vapor intrusion limiting interstitial condensation risks. Cut easily using fine tooth saws or knives with sharp scoring edges; comes supplied with durable foil-faced facing.
This product is ideal for use as insulation between studs in new conventional timber-frame walls of residential buildings up to 18 m in height, featuring masonry outer leaves. It meets Euroclass A1 fire resistance criteria, is non-combustible, has high water resistance, can withstand compression without creating air gaps that reduce thermal efficiency, is rot proof and offers good durability.
