In 1981, the first Energy Doctor retail center and factory opened in Prince Albert, Saskatchewan in northern Canada and soon Ram Manufacturing Ltd. became synonymous with energy efficient acrylic windows throughout North America.

Ram Manufacturing Ltd. premiere products included interior insulating acrylic windows that performed well in reducing drafts and condensation in not only the chilly northern Canadian winters but in all climate conditions. Within six months of the opening of the factory and first outlet center, Ram expanded their distributorships across Canada with the US following soon after.

Seven years later, Ram Manufacturing Ltd. entered the three-season Solarium industry trading as Northern Tropic Solariums™. Homeowners looking for an additional room where they could enjoy the feel of the outdoors while in a wind-free environment clear of bugs soon latched onto the Northern Tropic Solariums as the ideal solution for their needs. Featuring stunning three-season wood beam solariums with maintenance free aluminium exteriors, Northern Tropics soon became the industry standard and premiere three-season room in North America. 

The latest advancement of Ram Manufacturing’s product line is the four-season cedar beam sunroom – a new alternative that brings clients year round enjoyment from their new addition. Sunrooms come with a variety of performance glazing options to suit all customer and distributor needs while guaranteeing the unparalleled quality expected from all Ram Manufacturing products.

The success of the Ram Manufacturing Ltd. is attributed to the small town values that staff members bring with them to the job. Most of the original staff that began their careers with Ram Manufacturing Ltd. in 1981 still work for the company and maintain the exceptional standards that helped make their company an international success story.

Today, over twenty-five years later, Ram Manufacturing Ltd is still the North American leader in energy efficient products for both your home and business.

From the designers to the carpenters through to the management staff, Ram Manufacturing Ltd. promises their dealers and clients delivery of top quality products with exceptional customer service and small town integrity every time.
