Hammerglass® is a silica-coated polymer product – 300 times stronger than glass. Surface coating provides UV, chemical and abrasion resistance. The Hammerglass sheets are flat and come in standard thicknesses of 4, 6, 8, 10, 12 and 15 mm. Other thicknesses are also possible. The sheets can be hot-rolled, cold-bent, laminated, edge-polished and more. Hammerglass sheets are extruded by rolling liquid plastic granulate to the right thickness and then cooling it at room temperature. Black soot stains from the heating, dust particles, unevenness and rolling defects may occur, but should be sorted out in production control. Hammerglass AB has established levels for permitted variation in thickness, permitted black dot size and maximum distortion level (dioptre level). After extrusion, the sheets are coated with a double-sided Hammerglass coating, and further quality control is performed. Faults in the sheets might nonetheless occur. The purpose of this document is to set out guidelines for the quality assessment of products and the handling of complaints. The guidelines are based on the assessment of flat glass, described in EN 572.


Labelling and dimension specifications

With the exception of projects such as noise barriers, bridges and roof solutions, where it is easy to determine the installation time afterwards, all Hammerglass screens have their logo, manufacturing number and security class (if applicable) laser engraved. Labelling facilitates traceability in warranty cases, and supplier identification. In dimension specifications, the outer dimensions of the glass shall be given as Width*Height, expressed in millimetres.

Return of Products for any reason whatsoever shall require prior written approval of Hammerglass.

6. Warranty

Hammerglass warrants the Products will conform to the Specifications, unless otherwise agreed to in writing by Hammerglass in the Order Confirmation. Should Products, as delivered, be shown not to conform with the Specifications or the specification otherwise agreed in writing, as the case may be, or the quantity of delivered Products be shown to deviate from the agreed quantity, Hammerglass shall, at its own discretion and at its own costs, as the sole remedy of Purchaser, either (i) deliver new Products; (ii) repair the non-conforming Products; or (iii) refund such proportion of the purchase price received which correspond to the non-conformity or the shortage.
