76 STRUCTURAL ELEMENTS; EXTERNAL ENVELOPE
Aluminium curtain walling sets new standards in house building
with residential designs. Nonetheless, technical developments have gradually extended their scope, first to multiple occupancy housing projects and subsequently to architect-designed homes. Curtain walling has positive benefits in
M
terms of installation speed and cost. A facade frame of metal, PVCu or timber has vertical or horizontal elements which are anchored to the supporting structure to provide a non-load bearing external wall. Though PVCu is still used extensively in such situations it has drawbacks in terms of expansion and contraction. Aluminium is highly stable and offers a
far longer design life, its inherent strength and light weight enabling systems to be installed in spans of up to ten panels, each a metre wide. On bi-folding sliding doors, slimmer frames provide a sleek, unobtrusive
ention curtain walling to any specifier or house builder and it’s odds on they won’t associate it
transfer. Add to this the total recyclability of low environmental impact of aluminium and it has a high sustainability rating. Modern powder coating techniques now
appearance, a correspondingly larger glazing area removing any obstruction of sight lines to the external landscape. The resulting streamlined appearance is enhanced by the option of a low threshold with 13mm step for compliance with AD Part M. The thermal performance of aluminium
systems is also a commonly cited reason for their use. Those from Kestrel Aluminium retain heat effectively thereby limiting its
provide a standard of coating stability which retains the as-installed appearance for many years. Kestrel not only produces any RAL shade to meet project-specific requirements but dual colours to complement existing or planned facets of design. CALA Homes’ development of five and six bedroom houses on the Coton House Estate near Rugby has a Kestrel Aluminium 100mm box and plate curtain walling system incorporating 60mm casement windows. The dramatic frontages provide high thermal efficiency through use of polyamide thermal breaks and low U-value double glazing units. The end result is secure, energy efficient and stylish.
