Birtley Timber Frame Lintel TF50

Timber Frame Lintel with Expanded Polystyrene. Special features include lack of baseplate and factory fitted insulation; which reduces thermal bridging and post-fabrication galvanizing, leaving no surface with inferior paint protection. For installation use lintel clips at <600mm intervals, not more than 225mm from each end. As well as this, lintels over 1200mm must be propped until masonry is fully loaded and cured, with a 150mm minimum end bearing.
