Fixed Insert Secondary Glazing

Our premium standard glass option, perfect for most applications. It delivers around 50% + enhancement in thermal insulation and with the right air-gap 45dB sound reduction. If your primary window is 4mm or you have standard double glazing, we recommend mixing glass thickness for optimal performance. 4mm toughened glass is 2-4 times stronger than ordinary glass (float/annealed glass) of the same thickness. This safety glass meets building regulations for health and safety considerations, including distance from floor and doors.

This is 50% more material than the 4mm option. It can offer around a 50% + enhancement in thermal insulation and provides excellent sound reduction performance, with the right air-gap 49dB +. 2-4 times stronger than ordinary glass (float/annealed glass) of the same thickness, providing enhanced security and health & safety.

(widely known as Pilkington K glass) This is a thermal performance enhancing coating applied to the glass. The coating is an invisible, proven technology capable of increasing the insulation performance of the glass by 65% up to 10% more than a non-coated option, this is equivalent to a mid ranged double glazed sealed unit with a certificated U-value of 1.868 W/m²K. With special thin-film metallic or oxide coating allowing short-wavelength solar energy to be transmitted into a building, but preventing long-wavelength energy of the heating systems within a building from escaping; so conserving heat, it also reduces UVA & UVB solar radiation. Available in 4mm, 6mm toughened glass and 6.4mm Laminated glass offering the same strength, safety, acoustic and security performance as their equivalent non-coated versions. This is a hard coat application with a degree of robustness, but can be scratched if abrasive cleaning materials are used, see maintenance.

2 sheets of 3mm plate glass with a sheet of 0.4mm transparent ethylene-vinyl acetate (EVA) between. Moulded together under heat and pressure. The glass will crack without shattering. Also known as shatterproof glass. This thickness is considered a Class B safety glass (2B2). Enhanced sound proofing properties, equivalent or marginally better than a 6mm version.

Specially developed acoustic glass comprises of a PolyVinyl Butyral (PVB) interlayer which acts as a dampening core to prevent sound frequencies from vibrating from one pane of glass to the other. This absorbs and weakens sound energy, helping to act as a barrier to noise. This plastic interlayer also has the additional safety and security properties of laminated glass. This thickness is considered a Class B safety glass (2B2). Stadip Silence acoustic glass offers optimum sound reduction performance approx 51 dB to 53 dB is possible. However, it is a premium product and priced accordingly.

2 sheets of 3mm plate glass with a sheet of 0.8mm transparent ethylene-vinyl acetate (EVA) between. Moulded together under heat and pressure. The glass will crack without shattering. Also known as shatterproof glass. This thickness is considered to be a Class A safety glass. Enhanced sound proofing properties, equivalent or marginally better than a 6mm or 6.4mm versions.

Specially developed acoustic glass comprises of a PolyVinyl Butyral (PVB) interlayer which acts as a dampening core to prevent sound frequencies from vibrating from one pane of glass to the other. This absorbs and weakens sound energy, helping to act as a barrier to noise. This plastic interlayer also has the additional safety and security properties of laminated glass. This thickness is considered a Class A safety glass (1B1). Stadip Silence acoustic glass offers optimum sound reduction performance approx 51 dB to 53 dB is possible, It also has a slightly better performance with higher frequency sounds. However, it is a premium product and priced accordingly.

Heavy-duty laminated glass offering exceptional acoustic and safety performance. Available in standard, Low-E, and acoustic variants. The increased thickness provides superior sound reduction and enhanced security properties. Perfect for high-performance applications where maximum acoustic and thermal benefits are required.

Maximum acoustic performance glass designed for the most challenging noise environments. The substantial thickness combined with specialized acoustic interlayers provides exceptional sound reduction capabilities. Ideal for properties near busy roads, airports, or other high-noise areas where maximum soundproofing is essential.

Advanced double glazed sealed units available for Hinged Unit HD systems. Features two panes of glass with an insulating gas-filled cavity, providing exceptional thermal performance. Perfect for heritage properties or applications where maximum energy efficiency is required. Price on application due to custom manufacturing requirements.
