WHY USE CAPPING?
Whatever type of glasshouse you already own, or are contemplating purchasing, a important aspect is to save convected heat being transferred to atmosphere. One of the best ways of doing this is to have a Griffin glazing bar capping system fitted.

Using our patented snap-on capping in white or grey rigid PVC, we not only provide efficient, energy-saving insulation for the aluminium bar but also help to reduce glass slip and water leakage problems, prevent the growth of moss and algae on the glazing section, and dramatically improve the appearance of the whole structure. The capping will firmly hold glass of almost any thickness in position, and is supplied to the exact lengths required. If, for example, it is intended to cover a 20 ft span, then depending on the make and type of house, the bar capping would be 12 ft long and fit firmly onto the glazing surface from ridge to eaves.

Griffin bar capping is available for glasshouses by Cambridge, Robinson, Hancock, Alitex, Byron, Frampton, Wright Rain and possibly other makes. Certain profiles can also be applied to wooden glasshouses.

Our latest Class I LUXURY GLASS STRUCTURE which has been specially designed to comply with the demands of Building Regulations and, at the same time, have a very attractive appearance with novel features. It is aimed at the market of modern Garden Centres, special glass rooms for the domestic user and swimming pool cover. We have limited the range, at present, to 20 ft and 31 ft spans, and our normal doors are of the double glazed, toughened, patio type. The trusses are of a smooth, single portal design, leaving the entire roof space uncluttered. One very special feature worthy of note is that, within the thickness of the glazing bar (nominal 2 in) we are able to incorporate as standard, a special fire retarded insulation giving the skin a thermal insulation value equivalent to that of an 11 in cavity wall. Our unique reverse double glazing feature, gives the purchaser the ability to add a second internal skin of glass or virtually any substance for either achieving extra heat savings, safety or reducing solar radiation. This can be fitted at the time of erection or, some time (years) after the installation has been completed. We can often provide this same service to glasshouses of other manufacture.

Over a period of time, glass will inevitably become dirty and weatherstained, resulting in loss of light transmittance and possible breeding grounds for spores that will attack plants.

To combat these problems, Griffin offers a full glazing bar and glass cleaning service using high pressure jets perating between 750 and 1500 lb/in² to remove, as far as is practicable, accumulated moss and other debris, and to clear and wash out the drainage channels in glazing
bars.

Additionally, the Company is also equipped to carry out acid cleaning, both internally and externally, usually resulting in a house restored from the ravages of climate and organic deposits, and presenting a pristine "as new" appearance.
