Lift Out
Series 41: Heavy duty framing using Series 41 hinged profiles without hinges. Suitable for very large and curved windows; supports thicker glass for higher noise insulation.
Ideal for applications where access to the primary window is only required for cleaning and maintenance purposes. Larger glazing beads accommodate the use of sealed units.
Series 41 Heavy Duty
A version of the heavy duty Series 41 casement system without hinges that is suited to larger shaped and circular windows or those requiring thicker glass specifications. Release of catches allows the panel to be removed for occasional cleaning.

A Series 41 lift-out will reduce heat loss by up to 50% using standard glass, up to 65% with a thermally efficient glass (low-E). High performance compression seals will almost eliminate drafts and ensure much greater comfort near the window.
The effectiveness of the insulation is measured by U-values, the lower the figure the better the insulation.

A Series 41 lift-out set 100mm apart from the existing window will reduce noise levels by 45dB (decibels). In most circumstances this will achieve World Health Organisation guidelines for quiet living and working environments and the twin compression seals remain very effective over long periods.

The Series 41 lift-out is not designed for security but it is fitted with simple storm catches and, if glazed with laminated glass, will provide limited resistance to forced entry.
