We can even undertake installation if required, so we really do provide a total quality service.

Spandrel Panels

Spandrel panels are supplied as fire and sound rated timber frame panels, made to the profile of the roof. They remove the need to build up masonry party walls into the roof space and can therefore save weeks on a build programme. Supplied with built-in lifting straps they are installed alongside the trusses to form a fully compliant dividing wall.

Manufactured from a range of materials including plywood, OSB and plasterboard, the panels can be filled with solid-slab insulation and fire-treated as required. They are clad using the Fermacell panel.

Engineered Products and the Environment

At Alco Timber, environmental issues are important to us. We are pleased to say that our engineered products meet our high standards in this area.

When producing the engineered joists, an efficient process and reduced wastage mean that only 1/3 of the quantity of trees is harvested when compared to traditional timber methods.

The joist manufacturing process is also environmentally efficient, minimising water usage and recycling waste wood. The timber species used in the manufacturing process is abundantly available and sustainable, being self-rejuvenating and extremely fast growing, thus absorbing more CO2 greenhouse gases in the process.

Our suppliers implement regular ‘forest environmental quality’ reviews to ensure that all sources of timber are managed to acceptable environmental standards.
