Bubble Gasket

Bubble Gaskets are a well-known window seal that provides a compression seal when the window or door closes. This is achieved through a series of rubber or synthetic elastomer bubbles that extend across the length of the gasket. These 'bubbles' are made to expand under the pressure of the frame and sash, creating a high performance weather seal that helps stop air infiltration and draughts into your home.

They can easily be fitted into a groove in the frame or sash, without the need for adhesive. This makes it a simple and affordable solution to draughty windows, and reduce heating costs. As with all window seals, they are susceptible to wear and tear over time.

These tools are extremely beneficial for glaziers since they let them push the flat gasket spline into the window's groove without having to use ladders. They come in a range of sizes, and some come with a pointed end which is used to help push the gasket through awkward corners. This can help to reduce the amount of time needed to install windows, and it can also be used to make sure that the gasket is in line with the frame of the window.

Wedge Gasket

The wedge gaskets serve to seal the double-glazing unit and frames made of upvc to stop the entry of water, air or dirt. They are usually made of synthetic or rubber elastomers and have a wedge shape that gets narrower towards the end. They are pressed in place to create a tight seal. The wedge-shaped profile is compressed to give the necessary grip and to prevent leaks and drafts from escaping.

These kinds of draught-seals can be typically found in uPVC doors and windows, especially those with external beading. They are pushed in the groove or channel of the window, doorframe or sash frame to form the seal. They are easily changed if they need to removed for cleaning or repairs.

The draught-proof seal is wedge-shaped, like all other draught-proofing seals on the market, prevents wind gusts from blowing into the gaps between double-glazed windows that have plastic frames.

Most sealants on the market are available in a variety of different technologies that are further refined for specific uses like kitchen and bath, window & door or gutter installation. Contractors are prone to be stuck with one brand and not consider different technologies that can better meet their sealing needs on the job site. Hybrid sealants, because of their versatility are becoming a sought-after option for snagging among professional building tradespeople.

They combine the durability of silicones with the weathering resistance of polyurethanes. They offer premium performance characteristics that make them a good choice for building projects. They are tough weatherproof, paintable and weatherproof and can be used in many sealing applications, including expansion joints and splicing joints. They also have low odor and can be applied to wet surfaces.

They are able to adhere well to porous and non-porous surfaces, including concrete, masonry and brick, drywall and glass, wood, galvanized steel, aluminum, PVC, CPVC pipe fittings and boat hardware. They are made for use on wet or dry surfaces and are able to be used in temperatures as low as 20F. They are easy to gunned and feature smooth tooling. They also have a quick curing time which makes them waterproof and ready for painting in 30 minutes. They are low VOC and non-odorous, free of isocyanate, and mold, mildew and fungus-resistant.

They are also highly durable, UV resistant and weather-resistant. They offer an airtight barrier that is able to withstand and moisture penetration. They are also low in VOCs and contain a high amount of solids which means they won't shrink or break when exposed extreme weather conditions.

To make use of a hybrid sealant cut the nozzle of the cartridge or sausage to the desired bead size and apply a continuous bead along the perimeter of the frame and siding to create an impermeable seal. Utilize a caulk tool to smooth the bead, and ensure that it is neat and level. After applying the sealant let it cure for 24 hours before taking off any excess with a sharp blade or a scraper.
