Alpha Plus Modular Sunroom Kits

Three & Four Season DIY Sunrooms

Insulated Pre-Fab Patio Enclosures

 

Alpha Plus is HPPK’s original, proudly American-made modular DIY sunroom line, designed as a high-quality, more affordable option for creating a 3-season space and configurable for some 4-season applications. This do-it-yourself modular sunroom is classified as a “materials supplied” kit.

 

The Alpha Plus™ sunroom line is constructed with our 3 1/2” thick insulated aluminum wall system. Sitting on top of the walls is our exclusive, patented roof-lock WeatherGuard structural insulated roof system, available in 3″, 4″, and 6″ roof panel thicknesses. This allows you to design your sunroom for your particular climate. Whether hot summer sun or deep winter snow is your concern, our WeatherGuard roof is designed to provide the protection you need.

 

Designed as an efficient alternative to stick-building a full addition, the Alpha Plus system brings high-quality sunroom construction to homeowners in a modular, do-it-yourself format. It is suitable for 3- or 4-season applications.

Alpha Plus Sunroom Walls

Insulated R-14 Sunroom Walls! Low Maintenance!

Extruded aluminum structural framing, a 1.5 lb. EPS core with our patented Tuffcore vinyl laminated on both sides makes for the ultimate in wall panels.

 

The exclusively formulated vinyl framed windows come in either a fixed or sliding format with a choice of clear or Low E glazing. Our single pane or argon sealed double pane windows allow for a 3 or 4 season room construction.

Kick Panels & Transoms

All Weather & Indestructible! Low Maintenance!

Our TuffCore panels form the solid wall areas of your sunroom wherever glass isn’t used. Available in white or almond with stucco or pebbled finishes, they’re durable, easy to clean, and designed for a finished, low-maintenance look.

 

The TuffCore finish also helps improve the panel’s insulating performance, making it a strong choice for comfortable, long-lasting patio room construction.

Alpha Plus Door Systems

Full-View Pedestrian and Sliding Door Systems

Our 36″ wide pedestrian doors open like conventional doors and are available in either an in-swing or out-swing design.

 

We also offer a French double-door configuration, allowing both doors to open and lock independently. Our sliding patio doors operate like standard patio doors and create a smooth transition between indoor and outdoor living spaces.

Alpha Plus Windows

High Quality Vinyl Windows Choice of Glass Packages

All sliders include our EZ Glide Quad Roller system, available exclusively through C-Thru. It uses twice the rollers of many competitors to reduce sash racking and provide smoother operation.

 

Condensation inside a dual-pane window usually means the seal has failed. Our high-performance dual- and triple-pane glass uses advanced insulated glass seal technology.

How Does the WeatherGuard Roof System Work?

Strong Enough to Walk on! Low Maintenance!

Our WeatherGuard Insulated Roof System has a patented snap locking system (joining the roof panels together), eliminating exposed screws and unattractive obstructions in the ceiling. Our exclusive, patented snap-lock system, designed with internal weep channels, helps prevent unwanted water from leaking into your room. Making it hands down the industry’s most state-of-the-art system.
