Which Sealants are ideal for uPVC Windows and Doors in India?

In old windows, silicone sealants are still in use. But are they effective? As people move towards alternatives like uPVC windows and doors, it is natural that sealants of an improved quality will perform better. Double glazing fixtures are very efficient but a bad sealant can lower its performance in terms of energy efficiency, blocking harsh sunlight and rain moisture from entering the home. Indian homeowners need to ask the right questions from the uPVC windows and door sealant manufacturer to get the best results.

VEKA, is one of the excellent quality uPVC windows and doors suppliers in India. We take pride in fitting advanced fixtures across the country.

This blog post throws light on the need for sealants on window edges. If the sealing is incomplete, heat seeps inside. During the summer season, it is of nuisance value and defeats the purpose of a uPVC window.

The key role of sealants

A uPVC windows and doors sealant manufacturer knows the importance of covering the joints existing between window frames and external/internal walls. When double or triple-glazed glass is used, proper sealing is even more vital.

VEKA not only offers a proper design but also requires guidance to match the room requirement. A prospective customer gets solutions for:

• Drawing of the style chosen.
• Recommended sealant.
• Substrate tests.
• Experiments with compatibility adhesion and pollution.

For systemic applications used in windows and doors, sealing is part of the process. We use products that bond with the nature of the uPVC material being used.

In which room fixtures silicone sealant is used?

Owners can choose to have double-glazed windows across the home. The bathrooms and the kitchen are two locations that require a long-lasting finish around the windows. When used in the outer walls where the windows are fixed, the sealant should be very durable. It will have to resist outside weather and pass the test of rainfall, sunlight and moisture. Water ingress brings down the very purpose of a window, thus sealing it is important.

The choice of the sealant should be:

• Ideal for external applications.
• It should have multi-purpose properties to keep windows and doors safe.
• The sealant should be suitable for porous and non-porous surfaces.
• If it has antifungal properties it is good for bathrooms. Moulds do not appear easily.
• They also do a good job of closing gaps and cracks.
• After curing the sealant can be painted for additional security (only in case of interior application).

Are acrylic-based sealants good?

Yes, they have several benefits if you ask uPVC windows and doors suppliers in India. They are:

• Colour fast, dry and easy to apply.
• Ideal for an interior application as it can be painted to match the wall colour.

We also believe that a sealant is an important part of window installation for the following reasons.

• It takes care of the expansion & contraction of uPVC frames due to temperature differences by allowing flexible joints.

• It is applied on the perimeter of the window frame from inside and outside.

• Outer sealant needs to be a neutral

• The inner sealant can be acrylic-based so that it can be painted.

• It adds aesthetic value to the window when applied correctly.

VEKA technicians use the best products to conceal the gaps and make joints more strong. This is a prime requirement for uPVC windows and doors to function well. Get natural light and darkness as required. We help you to prepare better with the right product applications.
