Panels
Timber frame panels are manufactured in the factory for accuracy. All frame timbers are structural grade C16. Frame studs are usually @ 600c/c although internal sheathed panels have studs @ 400c/c to prevent deformation of the sheathing. Panels generally do not exceed 3.6m long to aid handling on site by erectors but panels can be made larger if and when required.
External wall panels utilise 90 or 140mm studs with an external layer of sheathing. Corovin Breather paper is then fitted using polypropylene tape and stainless steel staples.
Internal load bearing wall panels usually utilise 90mm studs but sometimes comprise of 140mm studs. Engineers may also call up studs at different centres to increase load bearing or wind resistance capacity.
External and internal load bearing panels as called up by the engineer have softwood or engineered timber lintels and in some cases steel lintels are used, these can in most cases be factory fitted.
Internal non-load bearing wall panels utilise either 90 or 63mm studs. These are left unsheathed but have a central row of noggins to help restrain them.
Insulation can be supplied by Taylor Lane. We supply, as standard, insulation which adheres to the Robust details E-WT-1. Acoustic and Thermal Compliance can be seen below.
Thermal Compliance:
We currently achieve the following U-Values:
Standard Panels 90mm 0.35 W/m².K ~ ISOWool HP Batts
140mm 0.30 W/m².K ~ ISOWool Standard Batts
The above are based on a timber frame wall with studs at 600mm centres, sheathed with 10mm OSB board, a nominal 50mm clear cavity and 100mm facing brick.
Acoustic Compliance (Party Wall Construction):
We achieve the current requirements specified by Part E of the Building Regulations and adherence to Robust Detail E-WT-1, through our stipulation that dry lining to party walls with a minimum mass of 22Kg/m2 per unit area, must be provided. Any joints in boards to be in staggered layers with intermediate insulation in each leaf to be 10 to 60Kg/m3.
