What to look for when choosing a window frame sealant
It’s always beneficial to have a choice in life, but when you’re faced with a whole host of products, making a decision can be tough.
There are various factors you may wish to consider when narrowing down your options and trying to choose the best window frame sealant product.
One of the most important considerations should be the materials used to create the frame.
Some window frame sealant adhere to certain materials better than others.
It’s also wise to think about the location of the window.
Although many products are suited to both external and internal use, some may have properties that are better suited to outdoor use.
If you’re sealing external frames, it’s best to go for those that are designed to weather the elements.
The type of joint is also an important factor.
If the frame is going to move as a result of changing weather conditions, for example, using a window sealant that is suited to high-movement or expansion joints is beneficial.
It’s also wise to look at aesthetic options.
If you’re desperate to preserve the aesthetic appeal of a property or facade, for example, you may wish to go for the product that offers the closest colour match to the frame.
If you’re trying to blend in with brickwork, for example, it’s advisable to opt for a sealant that comes in a range of brick-coloured shades.
Cost may also play a part, and it’s worth comparing prices and bearing your budget in mind.
