The Comar 7Pi LS+ lift and slide gearing are said to provide smooth operation for door configurations up to 12 metres wide and 3 metres high, creating glazed sliding walls. For the summer months maximise the opening space with the three-track slider which creates two thirds clear opening, whilst in the winter the lowest U-values are said to keep out the cold.
Optional slim interlocks are said to maximise the homeowners view out when the doors are in the closed position keeping the slim sightlines of Comar 7Pi LS+ doors with the lowest U-values, so, according to Comar, even in the coldest winter months daylighting is maximised and warmth assured. For a standard CEN size set of doors U-values are down to 1.4 with a 1.0 centre pane and using glass technology and Comar’s Enhanced Thermal Foam U-values of 0.74 are achievable.
According to Comar, the real advantage of this system is it’s ‘smooth and easy lift’ operation. Another advantage is said to be the ability to lock the door in an open position anywhere along the track which means that the homeowner can open the door for ventilation without the risk of small children and toddlers exiting the doors.
Comar Systems says it utilises multi-function profiles which means that from a minimum stock, all configurations of this system can be fabricated. Installers with the Comar Easyfit components can reportedly minimise time on site and disruption to the homeowner whilst maximising returns.
The company says that feedback from the UKAS Accredited Test House was that “it is the best they’d ever seen”, as it passed BS6375 Parts 1, 2 and 3 with no water leakage at 1050Pa. The hardware, has been tested to over 50,000 open and closing cycles.
