Have you ever wondered why some Roof Vents leak and others don’t?

To coincide with the launch of their new GlazaTherm™ Roof Ventilator, Lonsdale have published a guide entitled “Important Questions To Ask Any Roof Vent Manufacturer”. The questions are aimed to put manufacturers ‘on the spot’ and help designers and installers choose which vents have the necessary features to prevent leaks and offer durability for their clients.

Unreliable vents can prove costly due to the amount of ‘call-backs’ that installers might have to make in order to carryout remedial work to prevent persistent leaks, never mind damaging relationships with customers. The guide gives advice on what to look for in a vent to avoid such problems and further information about opening mechanisms, thermal performance and airflow. The different materials commonly used throughout the industry are assessed including pvcu and thermally broken aluminium using both the resin and the latest polyamide methods.

Lonsdale state Glazatherm™ is compliant with the latest requirements of Building Regulations Document L and is compatible with all the major domestic and commercial roofing systems currently available. Weather-tightness is of paramount importance and Lonsdale operate a 12 stage manufacturing process to ensure compliance with the Company’s vigilant quality control. Step by step installation instructions are provided with each vent to avoid mistakes and save valuable time on site.

Richard Burgess, Lonsdale’s Sales Director comments: “We can manufacture top or bottom hung vents suitable for both natural and smoke ventilation up to about 2.25m2 in area, subject to width and length ratios. Side hung is also an option where access may be required. These large vents are ideal for commercial installations, but as our prices are so competitive, GlazaTherm™ appeals to those conservatory companies unwilling to compromise on quality.”
