Double glazing has become a vital component for homeowners looking to enhance their property’s energy efficiency and comfort. Here at Andover Glass, we are a family-owned business dedicated to providing top quality double glazing solutions tailored to the unique needs of Portsmouth residents.
Double glazing features two panes of glass separated by a sealed gap filled with insulating argon gas. This advanced design significantly reduces heat transfer, helping to maintain a comfortable indoor temperature throughout the year while also lowering consumption. At Andover Glass, our years of industry experience and commitment to quality mean every installation is carried out with precision and care. We take pride in our expert craftsmanship and personalised service, ensuring each product meets the highest standards and enhances both the performance and appearance of your home.
