Sealtite Acoustic and Weather Seals

Improve Acoustic and Thermal Insulation

Sealtite is a range of acoustic and weather seals that will improve the insulation in your home or office. This solution enhances the performance of existing windows and doors by applying suitable draught proofing strips that is appropriate for the window or door style while maintain easy operation.

Why Choose Magnetite

Noise Reduction

Window or door seals can give up to 3dB of noise reduction across both high and low frequencies.

Thermal Comfort

With draughts through windows and doors accounting for 15% – 25% of heating and cooling, seals are also an effective way to insulate your home in winter and summer.

Custom installation

Our acoustic and weather seals are custom-fit to your timber windows and doors. The installation is relatively quick and can provide immediate soundproofing.

How Sealtite Works

Magnetite can retrofit seals to all styles of doors and windows both timber and aluminium. Sealing your home is an easy and cost effective way to improve the comfort of your home and office. Our methods and techniques allow us to fit seals and cater for gaps large and small without changing the operation of the window or door meaning this solution is a must for leaky and rattly doors and windows. Our Sealtite range includes perimeter seals, door stop seals and bottom seal.

Noise Reduction Technical Data and Results

Proven Results

Noise pollution is one the biggest problems faced in the cities today, particularly in a high-density living. Unwanted noise can be responsible for sleep loss and lack of concentration. This can lead to a deterioration of health through increased stress levels, headaches, high blood pressure and loss of hearing.

Noise penetrates windows through leaky seals or vibrations through the window structure. To reduce noise, a window should minimise air infiltration, hold enough weight to limit vibration and allow a large air cavity. This cavity, or air gap, is the key to secondary glazing.

Expert Advice:

CSIRO Research by John Davy shown an air cavity can effectively enhance sound insulation performance. The larger the air cavity the more noise the window system can reduce. Results show a wide air gap of 100-125mm will improve sound insulation by an average of 7dB(A) more than windows with a narrow gap of 8-13mm.

Single Glaze 3mm	3	0	23
Single Glaze 6mm	6	0	27
Double Glaze Narrow Gap	9-12	8-13	31
Double Glaze Wide Gap	9-12	100-125	38

The human ear is less sensitive to low frequency sound. According to a study released by the CSIRO, the human ear needs a change of 3dB to detect a difference in noise levels and the human ear perceives a change of 10dB as a doubling or halving of the noise level.

If you double the thickness of glass in a window the noise level will decrease by 3dB the least amount possible to make a difference. If the glass is laminated there is no perceived difference in noise reduction.

National Acoustic Laboratory Testing:

Working with the principles of noise transfer, Magnetite® and Soundtite are designed for high performance, which is achieved by combining air tight seals with the ability to maximize an air cavity and the flexibility to vary glazing thickness to suit. Magnetite® is excellent at reducing general noise such as busy roads, commuter trains and noisy neighbours. Whereas, Soundtite works well to combat low frequencies noise such as garbage truck, freight trains or airplane during take-off and landing.

*The Weighted Sound Reduction Index (Rw) is a measure for sound insulation performance of a single building element such as windows. The higher the Rw rating, the better the sound insulation.
