Quattro Seal Questions Recently asked by a Client

  • The seal is applied between the window frame and opening casement/sash, but still allows the window to open, is that correct?

Yes, the seal is applied in such a way as to provide an airtight gasket unique to the profile of the individual window, ensuring gaps of different sizes and shapes are treated effectively, whilst still allowing the window to function normally.

  • Is the product suitable for any window opening type i.e. outward opening, inward opening, sliding?

Quattro Seal is designed for use with any window type or profile where there is a rebate including hinged, sliding or pivot type windows.

  • Can it be used on any frame material?

The process allows us to use Quatro Seal on any frame construction including Timber, Aluminum, Steel, uPVC and Glass. The method of application may vary slightly with each window frame material but the net effect is exactly the same.

  • What preparation is required, and will the window need repainting after application of the seal?

Our trained and highly experienced installers will treat each window on merits by assessing the required amount of preparation depending on window condition. Generally, the area to be treated will be washed down, cleaned, dried and in the case of timber windows, may be lightly sanded and filled if applicable. The preparation is key to ensuring the efficacy and longevity of the product.

  • Is the seal always applied from the inside or does that depend on the type of window?

In the vast majority of cases the product is applied from the inside. There may be circumstances where external application would be required but this is rare and usually assessed at survey stage. Where external application is required, we would specify required access equipment to H&S standards.

  • Is the seal paintable or does a colour matched option need to be used? If so, what is the standard colour range?

The seal is normally white which is suitable for the vast range of applications. We can also provide translucent sealant where appropriate. Where specific colour matches are required, we would discuss the options following a free survey of the building. We do not recommend painting of the seal, although this may not damage the seal, it can look unsightly if the paint begins to crack and peel over time.

  • Does the seal dry with a gloss or matt finish and does it clean easily? Does it stain or discolour with age?

Quattro Seal cures to a matt finish but will normally blend well with the existing windows, which is why it is popularly used with Listed buildings. Any discoloration will depend on the environment surrounding the window and generally this would affect the window material equally.

  • What is the expected life expectancy of the seal and is it resistant to damage?

Salix have given Quattro Seal a persistence factor of 29+ years and Ofgem have given a lifetime of measure factor of 15 years. This ensures the product is firmly established as a long-term effective measure, unlike standard draught strips which will traditionally last a much shorter period and lose efficacy much more quickly, requiring new applications much more frequently. Quattro Seal is 2-3 times better than traditional draught proofing in the Carbon League Tables. The Energy Savers offer a standard 5-year guarantee with all applications with an option to increase to 15 years if required. This primary guarantee covers both materials and labour and, unusually, covers malicious damage also.
