Sound Proof Glassclose
Sound Proof Glass
-
200__orig_350x2631
Sound proof glass is achieved by reducing the vibration through a sealed unit, the most effective way to do this is to differentiate the two panes of glass. i.e. 4mm to the inner pane a 6.3mm to the outer. this breaks the sound waves passing through the unit and greatly dampens noise transmittance
Astraseal double glazed units are available in a number of configurations to reduce decibel penetration and give good acoustic performance. Glass units are available that will reduce not only background noise from the modern world but also to specifically reduce noise from road, rail and air traffic. If you have specific performance criteria that need to be met, simply let us know and we will endeavour to compose a sealed unit that will meet the requirements. -

Composite doors are now manufactured in-house and provide a fantastic way to make a real entrance to your home
An important factor in the Astraseal strategy for providing a comprehensive service to customers is the ability to remain as autonomous as possible. This philosophy extends not only to the in house manufacture of sealed units but also includes the recent commissioning of a glass toughening plant which enables the company to produce its own safety glass units within short lead times and at stable prices. To further compliment the Astraseal product range and in order to enhance price and delivery times the company has commissioned a new composite door manufacturing line producing a range of GRP slabs into Rehau frames with Winkhaus locking mechanisms. This initiative has enabled Astraseal the ability to offer a selection of six different door styles in four stock colours and two foiled options. This product is further enhanced by the in house glass manufacturing facilities through which we have created an exclusive selection of glass designs. Astraseal can now offer a high quality composite door produced at competitive prices with delivery times within two to three weeks of receipt of an order. This exciting prospect is further enhanced by the launch of the ‘ASTRAFLAME’ thirty-minute fire door and screen which is available in exactly the same design range as the standard composite but is an ideal solution for doors located in communal areas where there is a need to protect fire escape routes. A new Astraseal composite door brochure will be made available to trade customers together with samples and technical literature. The range of doors can be viewed on the Astraseal web site and prices can be obtained through direct contact with the trade office. The competitive pricing has been calculated to offer an attractive proposition for retail customers as an alternative to standard PVC panel doors but with reduced price disparity. -
