Roof and Patent Glazing

Patent Glazing is the perfect way to let natural light into your property. It can also be used to reveal that panoramic view that has, up until now, been largely hidden by your conventional tiled roof. Whatever the results you are trying to achieve, the Lonsdale Patent Glazing System is the perfect choice.

The Thermgard system incorporates a thermal break for improved performance and greater condensation control, double glazing, argon gas filled insulating units and contemporary clean looking powder coated aluminium profiles that can be finished in a huge range of RAL colours to achieve the perfect result. The system also offers an optional integrated guttering system to ensure that your roof will always be weatherproof and watertight.

There are many different glass options to choose from and different factors should be taken into account when making decision on which type to choose – we will of course make our best recommendations to assist those decisions that you make. For example factors that should be considered are:

Will the proposed roof glazing face southward or will it be exposed to large amounts of sunlight during the day? Does the proposed roof glazing face north or will it be sheltered for much of the day from the sun? Will the proposed roof glazing be above a habitable room? E.g. dining area

Glass units are available with:

- Tinted interlayers with a choice of blue, bronze, green, grey and neutral tints. These are particularly beneficial in south facing areas to reflect sunlight and stop the area below heating up too much.
- Low emissivity coatings on inner sheets and argon gas filled cavities to stop heat escaping from the room.
- Low iron glass on the outer sheets to maximize solar gain.
- Self cleaning, Pilkington Activ or Saint Gobain Bioclean units that breaks down dirt deposits and then washes glass during rainfall.

Lonsdale Patent glazing is perfect for new build projects. Take a look at some examples of our work below.
