Description:	Maximair 50 heavy duty extruded aluminium single bank louvre system.

Louvre blades mounted horizontally at a pitch of 50mm by means of aluminium clips onto extruded aluminium concealed vertical supporting mullions.

Blade joints are butted to give a continuous unbroken appearance, with thermal expansion gap.

Designed to provide excellent aerodynamic performance whilst maintaining above standard resistance to rain ingress. 

Accessories:		System has a wide range of accessories available including bird guards, insect mesh, single skin blanking plates, insulated blanking plates, mitred corners, perimeter flashings, integrated edge details to interface with all types of cladding systems and building constructions. 

		Louvres supplied as a series of fully assembled modules to form continuous louvre banks with an unbroken appearance .

		Single and double leaf louvred door sets either with stainless steel hinges, or with stainless steel pivots, stainless steel handles, stainless steel stops, stainless steel restrictors and euro-profile locks.

Finishes:		Mill finish extruded 6063 T6 aluminium alloy.

		-or-

		Extruded 6063 T6 aluminium alloy with a polyester powder paint finish (including Syntha Pulvin) in a wide choice of colours and gloss levels. 
		
		-or-

		Extruded 6063 T6 aluminium alloy with anodising in Natural Silver or coloured Anolok II.

Options:		Bird guards – 1.2mm expanded aluminium alloy, diamond mesh size 12.35mm x 35.05mm.

		-or-

		Insect mesh – perforated expanded aluminium alloy, diamond mesh size 3.5mm x 2mm.

		-&/or-

		Security guards – 1.6mm stainless steel, square mesh sizes 5.8mm x 5.8mm. 

Technical Information:-		Principle components manufactured from extruded aluminium for strength and accuracy to meet 6063 T6 specification.

		Clips are manufactured from aluminium for strength, durability and security. 

		Where appropriate, fabricated components are manufactured from 1.5mm thick flat aluminium BS EN 485-2 : 1995, material generally EN AW-1050A Alloy, H14 (Al99.5).

		Standard louvre depth including mullion – 100mm.

		Profile Thickness – 1.5mm minimum.

		Louvre blade vertical pitch – 50mm.

		Weather performance – subjected to rigorous independent weather testing carried out by B.S.R.I.A. (The Building Services Research Information Association) using a simulated 13m/s wind speed together with a 75l/hr/m² water supply directed onto the louvre face with a further induced core ventilation flow of 0m/s to 3.5m/s and measured to be up to Class B.

		Measured Free Area – 49%.

		Aerodynamic coefficient of 0.235 to be used to calculate pressure loss and airflow rates by the Project Mechanical Consultant.

Design:	All design details/specifications are to be approved by Architect/Agent before manufacture.
