ADVANTAGES and BENEFITS
Hambro® has superior U.L. Fire
Ratings for 1, 2 and 3 hours, and eliminates the need
for fire dampers.
Hambro® has an STC 57
– one of the highest in the industry - and an IIC
30 on bare concrete. Hambro®’s IIC with soft vinyl
is 55, and with pad and carpeting it increases to 69.
Features open web configuration, no bridging and 4’
to 6’ joist spacing accommodates MEP
Support (mechanical distribution) within the joist plenum.
Hambro® permits full-length ducts and pipes, and virtually
eliminates dropped ceilings and sofits.
A Variety of Bearing Systems:
Hambro® is appropriate for a variety of bearing
systems: steel stud, masonry, steel & concrete frames
and wood framing.
design provides a floor that is 2 to 3 times more rigid, with one-third the deflection of typical bar joist assembly. Hambro also provides 4' joist spacing without bridging and bracing. Typical bar joist assemblies are spaced at 2' or 2'-6" on center and require bridging, bracing and metal deck.
Hambro® reduces building height and develops savings in the
cost of skins and all other vertical components.
Ease of Installation
The Hambro® System is easily installed
by one of the many experienced installers who contract with
you directly and package related scopes of work, or by your
own forces if you choose.
Hambro® is well-suited to a variety of projects including Apartments & Condos, Assisted
Living, Highrise, Hospitality, Independent Living, Medical, Office,
Religious & Assembly, Renovation
and Schools & Dormitories.
Slab penetrations are
easy using either sleeves, styrofoam or wood blocking prior
to concreting. No tendons and fewer joists offer flexibility.
Slender 3,000 PSI slab makes coring simple, if necessary.
Details have been developed as an aid to specifying professionals
