Double glazing is made up of two layers of glass, with a layer of argon gas in between. This type of glass can be used in Aluminium windows. The gas is a poor insulator, helping heat to stay in your home and making your windows more efficient. As well as trapping the argon gas, the second layer of glass reduces the amount of noise that enters your property, and helps to make your windows stronger and more secure.
Y Felinheli
Y Felinheli, formerly understood in English as Port Dinorwic, is a town, area as well as electoral ward beside the Menai Strait between Bangor and also Caernarfon in Gwynedd, north-west Wales. The population of the village was 2,284 at the 2011 Census. Y Felinheli has its beginnings in two communities, Tafarngrisiau near St Mary's Church and also Aberpwll to the north-east where there was a mill on the Afon Heulyn. The mill was reconstructed closer to the sea in 1633 and provided its name to the settlement. The location was mostly farming up until the location was changed by slate quarrying in the 19th century. A brand-new dock was built in 1828 when lime was extracted at Brynadda and also slate and lime were filled and culm (coal dirt or anthracite slack) was brought in to fire the lime kilns. The owners of the Vaynol Estate, the Assheton Smiths, possessed a lot of the land in Y Felinheli and also created the Dinorwic Quarry in the late 18th century, They also built the harbour to export slate carried to the quay by the Dinorwic Railway, a narrow gauge railway that was consequently changed by the Padarn Railway. Industrial development offered Y Felinheli (Felin-hely, 1838) the different name Port Dinorwig or Port Dinorwic.
