Timber Engineering Notebook series. No. 11: Cross-laminated timber construction – an introduction

Structural insulated panels (SIPs) are engineered, load-carrying, timber-based panel products that can be used in walls and roofs of residential and light commercial buildings. These lightweight panels combine the structural and thermal envelope of the building; they are manufactured offsite in a factory and shipped to the construction site, offering advantages to the build programme. This panelised form of construction allows SIPs to be assembled to form highly airtight, energy-efficient building envelopes.

This article continues from the previous instalment in the series, and aims to guide engineers in assessing the extent of corrosion of steel frames and in selecting appropriate treatment methods.

A review of glulam in two of the most common structural forms: 'post and beam' and two dimensional rigid frames.
