Medium Duty SBMkl Curtain Wall
Designed	for	applications	spanning	up	to	three	floors,	 the	versatile	SBMkl	system	successfully	combines	 high	performance	features	with	architectural	flexibility	 for	efficient	yet	economical	building	solutions.

Features
•	 A 	 vailable	both	single	and	double	glazed,	 the		system	is	thermally	improved	and	can	 accommodate	infill	panels,	fixed	and	opening	 lights. C 	 lean,	narrow	(45mm)	sight	lines	and	slim	 profiles	for	visual	appeal. T 	 here	are	four	size	options	for	the	SBMkl	-	50mm,	 75mm,	100mm,	140mm	and	a	range	of	four	cap	 sizes	for	maximum	design	flexibility. T 	 he	robust	construction	uses	aluminium		spigots	 and	is	easy	to	fabricate. T 	 he	system	is	fully	compatible	with	other	 Technal	products	including	entrances,	doors,	 and	windows	and	will	accept	a	wide	range	of	 architectural	hardware.

Purpose	designed	fixing	brackets	to	suit	project SBMkI	(Scale	1:3)

Construction
The	SBMkl	Curtain	Wall	comprises	a	split	tube	 mullion	construction	with	a	"screw	on"	external	 pressure	plate	system	and	a	selection	of	clip	on	 covers	to	produce	strong	yet	slim	aluminium	sections.	 The	split	tube	system	also	has	the	added	benefit	 of	concealing	all	the	fixings.	When	necessary,	steel	 strengthening	members	can	be	accommodated	 without	the	inconvenience	of	forcing	them	inside	a	 hollow	profile.

Size and Weight Limitations
The	critical	factor	in	designing	a	curtain	wall	screen	 is	wind	loading.	BS6399:	Part	2	(Formerly	BS	CP3:	 Chapter	5:	Part	2)	may	be	used	to	ascertain	the	wind	 loadings	applicable	to	the	given	location.	This	should	 be	specified	to	enable	the	designer	or	fabricator	to	 select	the	correct	profiles	for	the	project.	Design	 criteria	are	available	upon	request.

Glazing Specification
Glazed	to	BS6262,	SBMkl	can	accommodate	glazing	 or	panels	between	6mm	and	28mm.	Technal	windows	 can	be	inserted	into	the	curtain	wall	system	to	permit	 ventilation	or	smoke	venting,	as	required. The	glazing	uses	a	pre-shimmed	tape	inner	seal	and	 a	black	nitrile	to	BS7412	gasket	for	the	outer	seal.

Weather Performance

Heavy Duty SBMkll Curtain Wall
Mastic
The	SBMkll	is	a	heavy	duty	64mm	framing	system	 specifically	designed	for	applications	where	large	 inter-span	modules	are	required.	Through	the	 efficient	use	of	aluminium,	the	system	is	a	highly	 durable,	aesthetically	appealing	and	cost	effective	 curtain	wall.
