Secondary Glazing Benefits

Secondary Glazing Styles

80% SOund insulation
Significantly outperforming double and triple glazing, well-fitted secondary glazing offers the most effective noise insulation. From noisy roads to noisy kids, our internal windows can reduce noise levels by up to 54dB.

Secondary Glazing continues to grow in popularity, in no small part thanks to its unique soundproofing capabilities. The key to minimising noise levels is to install an extra barrier that sound waves find it difficult to pass through .

To achieve optimum acoustic performance, we advise that the secondary glazed window is installed with an air cavity of 150mm – 200mm from the primary window. Blinds and ornaments can still be displayed on the windowsill as JMP’s secondary glazing is slimline and discreet.

Just 64dB of noise can be problematic, whilst levels between 70-125dB can be painful, disrupt sleep patterns and increase levels of stress, a passing diesel bus may reach up to 85 dB.

Sound can penetrate the smallest of holes, JMP’s secondary glazing is manufactured on state of the art CNC machinery, and this ensures a tightly sealed frame. This teamed with correctly specified acoustic glass and a high-quality installation will significantly reduce the volume from external sources, eliminating it or reducing it to a whisper

Special laminated acoustic glass is used to maximise the noise reduction from all types of obtrusive noise. JMP has cured noise problems for 1000’s of homeowners covering all of the UK.

Working with our trade partners, we can guarantee the highest levels of product quality, a discreet installation and exceptional customer service.

65% thermal insulation
The installation of secondary glazing acts as an insulating barrier, with the correct glass and air cavity, the results will create a warm and secure home often reducing heat loss by as much as 65 perfect.

Warmth is a valuable commodity and creating a second barrier to the elements is an ideal way to reduce wasteful thermal heat loss. In fact, there are few better ways. A large proportion of heat is lost through your existing windows. Installing secondary glazing will ad an extra barrier to prevent heat from escaping.

JMP’s secondary glazing is supplied with an FSC approved timber subframe. This timber subframe acts as a thermal barrier preventing cold transference, this can reduce levels of existing condensation and increase thermal insulation.

To offer optimum thermal insulation we recommend that secondary glazing is fitted with an 80mm air cavity, low-E glass is often the best choice as it reflects heat back into the room. It has been designed and engineered to provide:

  • The very best thermal insulation
  • Maximum energy conservation
  • An extremely discreet installation
  • An environmentally friendly solution
  • An affordable investment with quick returns

Whether it’s for the added security, noise reduction or energy efficiency, our secondary glazing is backed up by an industry-leading five-year warranty on frames and glazing and a two-year warranty on moving parts.

Ensuring total quality, our products are manufactured in house at our 50,000 square feet manufacturing facility. With an on-site powder coating and arching facility, we can customise our windows to match the look, style and function that you require.

We have partnered with over 1000 local trade installers that cover the whole of the UK. Our network of trade partners install on our behalf and offer the very best thermal and acoustic installation.

JMP’s products not only provide excellent thermal and noise insulation, our choice of finishes and styles have a discreet, unobtrusive finish that is sympathetic to the surroundings and most existing window styles.
