GGR Glass brings you this blog post, to explain what a window finishing trim is and what it is used for, so read on for more information on this.



Window Finishing Trim - What Is It Used For?

Finishing trim is used to hold windows and doors in place. Finishing trim is otherwise known as window sealant or caulk. The window finishing trim or sealant not only makes window fitting look nice and neat in your home but it serves a purpose too.

Sealant trim is there to make sure that no air or moisture passes through, ensuring your home is watertight and weatherproof.

Without window trim, your home could be subject to draughts, moisture and mould spores can form as a result. Window trim is therefore an essential part of window fitting.


What Is Window Trim Made Of?

Window trim can be made from a variety of materials and is usually white in colour. One of the most common materials that window sealant is made of is silicone or acrylic latex.

Silicone sealant is the most popular type in the glazing industry. This is because it is highly versatile, it is extremely weather resistant, waterproof and long-lasting too. These are features that must-have qualities for a sealant that needs to secure windows and doors.

Silicone is a popular type of sealant that is used all around the world. It not only is useful in the glazing industry on windows and doors but thanks to its useful properties, it can also be used and is the perfect accompaniment to sealing in kitchens and bathrooms too.

Silicone sealant is constantly used to seal sinks, taps, toilets, baths, showers, lights, and anything related - the list goes on! This makes it a popular caulking material to use in the construction and plumbing industries too.

Silicone sealant can be more expensive than other types of sealants, however, it is worth the investment because it is so durable and long-wearing.


Why Window Trim Is Important

Creating a trim around your windows is important for a number of reasons. Not only is keeping the weather out including the rain and wind, but it is also essential for keeping your home as energy efficient as possible.

Many homes that have old sealant or windows suffer from energy wastage through air escaping from aged window trims. This causes homes to lose heat and makes energy bills increase as people continue to turn up their heating - ultimately causing a larger carbon footprint.

Protecting homes with window trims that are fresh, current and durable helps homeowners benefit from this energy bill and other reasons as discussed. Energy bills stay low and you have a warmer home overall, with no mould spores brewing.


How to Get the Perfect Window Trim

We will go over some of the top tools that you can buy, that can help you create the neatest and most importantly, functional window trim that is weatherproof and airtight.
